Using a Thermal Imaging Camera to Identify Heat Loss at Home

By Guest Blogger Katherine Ogilvie

A badly insulated home is not only bad for the heating bills but also for the environment. More efficiently heated homes means less heating is necessary and thus there is less burning of fossil fuels to meet the demand for energy.

In the UK, heating homes is one of the main sources of carbon dioxide emissions; in 2004 it was found that roughly 30% of the entire UK’s emissions (that’s over 40 million tonnes of carbon) came from heating houses. Because of their significant environmental impact, carbon emissions from housing have been the target of government schemes with grants to aid individuals to make their homes more energy efficient (such as the Green Deal). However, many individuals are still unaware of how much heat their home is losing.

There are tools available to help, such as this calculator allows you to enter the dimensions of your home and estimates how much carbon dioxide and money you could save if you were to invest in insulation. For instance, for a medium size semi-detached house proper insulation could save over 10,000 kWh of heat loss, £510 per year and over 2,800 kg of Co2 – an overall saving of 76%.

What’s more there’s a general consensus on which parts of a home tend to lose the most heat; 25% of heat is lost through the roof, 35% through the walls, 15% through the floor, 15% through doors and 10% through windows.

While the generalisations of where heat is lost from most homes is good for giving you a rough idea of where heat could be saved, every home is different and is likely to be losing heat from varying locations. This is where a thermal imaging camera can be incredibly useful, it instantly provides a visual depiction of where heat is being lost in a specific home and therefore what home improvement could be of the most use.

There are various types of thermal imaging cameras which can be of use when identifying heat loss in the home:

FLIR Ex-Series

From $1200

The Ex-Series FLIR Cameras are easily the most popular in the thermal imaging camera market for those with a larger budget. Even so, several electrical test equipment outlets do offer them for hire but it is clear that you get what you pay for, especially when it comes to FLIR products. FLIR’s patented MSX technology displays thermal images of outstanding quality and in real time, making inspecting and observing a cinch.

The spotmeter function which comes on the E4, E5, E6 and E8 models allows the user to provide temperate information on every pixel. The key difference between each model is the thermal image quality which ranges from 80 by 60 pixels for the E4 all the way up to 320 by 240 pixels on the E8 (an image demonstrating the range of resolution can be seen below). The other differentiator would be the temperature differences from as small as 0.15 on the E4 to 0.06 on the E8. These easy to use point and shoot style cameras are ideal for detecting insulation loss.

Thermal Imaging Smart Phone Extensions

Currently there are two main contenders in terms of thermal imaging cameras as phone additions, the FLIR ONE and the Seek.

The specs of each model are equivalent to low end of the aforementioned Ex-series range, with the FLIR ONE with a resolution of 80×60 (same as the E4) and the Seek with a resolution of 206×156 (somewhere between the E6 and E8).

However it is worth mentioning that the FLIR one combines its infrared image with images taken from the visual camera, which helps to provide a clearer picture – providing outlines of objects. As you can see from the picture below even though the thermal image on the FLIR one has a lower resolution, when combined with data from the visual image the output is easier to interpret.

The seek has a similar feature that provides context to the thermal image, known as the thermal + mode. Which produces a spilt screen, half the visual image and half the thermal image, as you can see below:

These models are ideal for checking the heat efficiency of a home because they offer a practical level of resolution but are a much more economical option with the FLIR ONE priced at $349 and the Seek at $199.

If you are considering purchasing one of these, it is worth noting that the FLIR ONE is only currently available for the iPhone 5 and 5s, although they are planning to release an android version. However an advantage of the FLIR ONE is it doubles up as an iPhone charger whereas the seek takes up the port needed to charge the phone. The Seek has an android version and can be used on anything from an iPhone 5 onwards.

The Seek also has various settings which could be of help when trying to identify heat loss in a home. For instance low mode, the camera will jump to and spot the coolest point in the field of vision – effectively finding the cold areas in your house so you don’t have to scan the photo/videos. There is a threshold mode which is applicable to this situation, you can set a temperature and get the camera to only show objects that are above, below or at that temperature. This could again be useful in locating cold spots, only highlight areas under room temperature for example.

The seek is the more affordable option, with better thermal resolution but a less professional final image. If you’re utilising the camera in a professional context (inspecting houses for their heat retention or as part of a property valuation) then it might be worth investing in the FLIR ONE for the extra cost, whereas if you’re just looking to evaluate your own home it could be worth getting the Seek. However, renting a professional thermal imagining camera on a single occasion is likely to be cheaper than both these options.

Thermal imaging cameras can provide valuable insight into home heat retention and are a key tool into ensuring homes are properly insulated which in turn can help to lessen our dependence on fossil fuels.

Aluminet Shade Cloths Review

Ever since greenhouses have been used for gardening, crop growing, and farming, many people have been finding new ways to yield better and healthier plants. However, it is difficult to find green technology in which truly combines cost-efficiency and eco-friendliness. In recent years, greenhouse thermal screens were invented and sold in the market to meet the growing demand of upgrading greenhouses and improving light diffusion. Also, out of all the greenhouse thermal screens released, Aluminet Shade Cloth remains unbeatable when it comes to its benefits, efficiency, and durability.

If you are considering getting shade cloths for your greenhouse, there are several things that you will need. An Aluminet Shade Cloth can provide your greenhouse with all the basic essentials. Not only does it equip you with all the necessities for growing crops and all kinds of plants, but it also has several features specifically designed to promote optimal plant growth and higher yield.

Significant Heat Reduction in Greenhouses

Greenhouses were initially designed to maintain static temperatures within the apparatus especially during winter in which temperatures are too destructive for plants. On the other hand, seasons such as summer and spring may cause the greenhouse to overheat thus causing detriment to the plants within. Greenhouse thermal screens were created to reduce the heat and to shade the plants from direct sunlight as it was found to be quite harmful for the growth of plants. In addition, shade cloths also make working within the greenhouse more tolerable at the peak of the heat. Gardeners and farmers will not have to leave periodically in order to cool down and have to suffer the dire consequences of being exposed to direct sunlight for long periods of time. Aluminet Shade Cloth is unparalleled to other greenhouse thermal screens available on the market. According to statistics, Aluminet can significantly reduce heat in greenhouses compared to other thermal screens.

State-of-the-Art Thermal Regulation

More often than not, the plethora of greenhouse thermal screens does not have features which can regulate temperatures within the greenhouse as effectively as it ought to. Aluminet Shade Cloth acts as a greenhouse thermal blanket. It controls the temperature of the greenhouse as well as normalizes the entrance and exit of infrared radiation. The drastic and rapid shift of temperatures in a greenhouse has been known to stunt plant growth and even prevent fruiting. Once you install Aluminet Shade Cloths you lessen the chance of experiencing leaf dry outs and soil corruption. If you want your greenhouse to be as efficient and productive as possible, only trust Aluminet greenhouse thermal screens to protect your plants.

Oh, and by the way, I have first-hand personal experience using this product and it really does work.

 

Hy-Cycle Fuel Cell Bike Reveiw

Commuting is a big part of everyday life, whether by train, car, or bicycle. Many travelers look to find a greener and more environmentally friendly way to get from point A to point B, but find that cycling can sometimes be too difficult or tiring. Cue the fuel cell bike. Fuel cell bicycles aren’t a new concept, however they haven’t really gained momentum in the consumer market just yet.

The process of making a fuel cell bicycle for practical use has been relatively difficult, which is perhaps why the market has remained stale. In 2006, a company known as Veloform was developing a methanol fueled three wheeler, which they called the City Cruiser II. Just a year later, a Chinese company, Shanghai Pearl Hydrogen Power Source Technology Co., introduced a hydrogen fuel cell bicycle that cost around $2,600, and had a fuel tank distance of nearly 60 miles.

The newest generation of fuel cell bicycles comes from a group of students at the University of New South Wales in Australia. The school researchers have developed the Hy-Cycle (pictured at top), a hydrogen fuel-cell bike that boasts an 80 mile fuel tank distance, which roughly equals about $2 worth of hydrogen. The fuel canister has a capacity of 2.5 kilograms, and it may take a little effort to fill, but researchers are now working on ways to increase hydrogen storage capacity.

The bicycle was designed and built by technical office Paul Brockbank from the University’s School of Chemical Engineering, and associate professor Kondo-Francois Aguey-Zinsou. The hydrogen cell makes climbing hills or long distance commuting easier on travelers by providing assistance with pedaling the bike.

Since electric bikes are already popular item on the market, critics of the fuel cell bike suggest that it makes more sense to use a battery to power the bike as opposed to hydrogen. However, the fuel cell on the Hy-Cycle can lead to the development of hydrogen powered bicycles to finally make their mark on consumers as a cheap and sustainable form of transportation. Aguey-Zinsou says that a key market for the Hy-Cycle are cities like London and Paris, which are currently renting bikes for hire for business people and the like to commute to and from work.

The biggest advantage to the Hy-Cycle is the ability to use hydrogen as a clean, sustainable, and safe source of energy. Hydrogen storage has been a researched topic for years, as scientists and engineers try to find a safe and effective method of storing compressed hydrogen. Because hydrogen is a light gas, it’s difficult to contain in a compact form.

The Hy-Cycle features a 2.5 kilogram canister located near the pedals. The fuel cell is under the seat, and aims to provide continuous recharging to the lithium ion battery that powers the Hy-Cycle. The developers are studying new methods to store 100 liters of hydrogen in the same canister, but while using only 30 grams of metal hydride, which makes for user-friendly and safe storage of the hydrogen fuel.

 

Spray-on Solar Cells – Go Paint Your Wagon

One of the hindrances of solar cells is their cost-to-power ratio where in most cases the cost of an effective solar panel simply is expensive compared to the power that is generated. While there are many efforts to increase the power generation of solar panels, other efforts are being made to reduce their overall costs.

One of the most interesting efforts is the development of spray-on solar cells that cost a fraction compared to solar panels, but cover a very wide area for maximum solar absorption. This new technology promises an incredible amount of potential for a relatively low cost.

Developed at the University of Sheffield by a team of scientists, this effort creates what’s known as perovskite solar cells which is a new material that holds a great deal of promise in the solar industry. This is because it overcomes one of the potential stumbling blocks of the otherwise high cost of creating solar panels.

How Perovskite Works in Harnessing the Sun

For years, scientists have been looking for a means of spray painting to create solar cells that use semiconductors of organic origins. Perovskite, a calcium titanium oxide mineral, represents a real breakthrough in creating a more efficient form that can be widely used.

First demonstrated in 2012, the perovskite proved to create efficient photovoltaics which are needed to capture and transmit solar power. The spray painting process works quite well because little of the material is actually wasted and it can be scaled for high volume manufacturing in a similar way to applying paints to graphic arts or to vehicles.

The interest in perovskite has been growing considerably since it was first demonstrated as it is very cheap to produce, yet it can be applied to a wide number of applications. This is because most solar cells use silicon which takes a great deal of energy to produce. Perovskites on the other hand take very little energy to create.

The Future of Spray-on Solar Cells

Where this form of spray-on solar cell will have its maximum impact is in the amount of energy that is created using a cheap form of materials. While perovskite is not quite as efficient in terms of energy conversion as silicon, the substantially lower cost of the materials has made it one that has generated a lot of interest from manufacturers.

Currently, perovskite generates about 19 percent conversion compared to silicon which is 25 percent in terms of absorbing and converting solar energy. Perovskite replaces the organic cells that were used as part of the light absorbing layer which previous versions were only about 10 percent in terms of absorption. Perovskite is not only more efficient, it is very cheap and will no doubt start replacing the organic light absorbing layers.

There is still work to be done in getting perovskite to becoming even more efficient, but the fact that it does cost significantly less than previous organic versions and is easy to apply is causing the solar industry to rethink how it creates panels for energy absorption. As a renewable energy source, perovskite is helping to overcome one of the main issues that have kept solar panels relegated to a supplemental source.

 

5 Amazing Eco-Friendly Technologies for the Future

It’s difficult to comprehend how quickly our world’s population is expanding. To put things into perspective, there were roughly half the number of people alive in the 1970’s compared to today. At this current rate, of roughly 80 million people being born per year, there will be 8 billion people living on our planet by Spring 2024.

This is a staggering influx and means that our natural resources are being stretched to breaking point. Throughout the world, from South-East England to South Korea, there is now an innumerate demand for clean water, affordable food, and sustainable energy.

As a result, one of the greatest challenges facing scientists and governments is finding clean and renewable energy resources. Money is being poured into research which can solve our eco problems, meaning that technology is now also developing at a phenomenal rate.

With that in mind, here is a guide to 5 of the most exciting and promising technological advances which could change the way to produce and consume energy in the future.

 

5. Microgrids

A microgrid is a small-scale version of the centralized electricity systems which are currently located throughout the UK. However, unlike their larger counterparts, these grids work on a local level and provide energy directly to a community. There’s no enormous startup costs and there’s no need to transport the energy over significant distances to reach consumers.

But how will microgrids change the way we produce energy in the future?

First of all, microgrids can help to reduce a community’s carbon footprint. Through harnessing solar energy, for example, a microgrid can produce only the amount of electricity needed by the community. Furthermore, it can capture any residual heat that is wasted and reuse the energy to fuel homes.

Most important of all, however, is that microgrids give communities the opportunity to produce their own energy; thus freeing them from dependence on large grid companies. This is a good example of ‘bottom-up’ consumerism and means that energy production will become an open market for all. Microgrids have already become popular in rural India, for instance.

In the future, microgrids could allow clusters of households across the world to produce their own clean and renewable energy.

 

4. Pelamis Wave Power

Pelamis is an Edinburgh-based company who have designed and manufactured an incredible piece of technology, the Pelamis Wave Energy Converter.

The Pelamis machine is made up of 5 large inflatable tube sections, each connected together by joints, which is then placed onto the ocean surface. As waves crash against the machine, the movement created within the Pelamis is converted into hydraulic power and then into electricity. This energy is then harnessed and sent back to shore using subsea cables.

The Pelamis machine generates green electricity which can be used for a variety of purposes. It can also be installed across the world, meaning that it’s not just useful in the North Sea.

This technology is still in its infancy, but the Pelamis has already demonstrated remarkable success and will potentially change the way we source our energy in the future.

 

3. Solar Cells

Everyone knows about solar panels, but it’s certain that this technology will see incredible advancements in the near future. Solar panels are being widely produced in China, allowing consumers in the East and West to purchase them incredibly cheaply compared to in the past. However, these panels are most commonly made from silicone cells. Silicone is cheap but it only absorbs a fraction of the sunshine which it’s intended to convert into electricity. That’s why solar panels are being revolutionized.

John Rodgers, a scientist from the University of Illinois, has devised a new kind of solar cell which is much more efficient at utilizing energy from the sun. Rather than using one cell, he has stacked four on top of another to create a ‘super’ cell. This might not seem terribly clever, but the results are staggering. His new cells are able to improve solar panel efficiency by 50% or more.

As more and more people embrace solar panels, it’s apparent that technology will continue to develop in a way that makes them much more efficient. This may include a gradual shift away from silicone cells to multi-layered cells.

 

2. Green Concrete

People have been producing and building with concrete ever since Roman emperors ruled the Mediterranean. However, concrete is one of the least environmentally-friendly products humans frequently use. Creating cement involves heating limestone to 1450 C and emitting a frightening amount of carbon dioxide in the process.

Our demand for concrete is unlikely to decrease, but scientists have discovered a way of making cement which actually absorbs carbon dioxide. The blocks are made from magnesium and are actually much stronger than their counterparts. However, during the hardening process, the concrete absorbs carbon dioxide; thus helping to improve our atmosphere.

 

1. Hydrogen Fuel Cell Cars

Just as everyone is getting used to electric cars, it seems that hydrogen-fueled cars will become increasingly important in the future. Hydrogen is the most abundant element in the universe, so it only makes sense to utilize the element for our energy purposes. You can already lease hydrogen vehicles in California but they are not yet available for public purchase.

The great thing about hydrogen cars is that they run on hydrogen and oxygen from the air. As a result, they don’t send any dangerous pollutants into the atmosphere or consume finite fossil fuels. Some elite car manufacturers have already created hydrogen cars, such as Hyundai and Honda.

If you’re wondering where fuels cells come into this, then here is how the car works. The fuel cell uses hydrogen and oxygen from the air and uses this to create electricity. The hydrogen and oxygen recombine and is released back into the atmosphere through steam. This means that we won’t ‘use up’ any hydrogen or oxygen.

Electric cars are fantastic, but they are dependent on electric outlets and some consumer report “range anxiety” with battery electric vehicles. Hydrogen cars, however, have a greater range, can be refueled in 5 minutes or less and also have zero emissions.

 

Final Thoughts

There are numerous challenges currently facing humanity, and there have been incredible efforts in recent years to solve our energy crisis. In the future, we will produce and consume our energy in an entirely different way. Hopefully some of the technology mentioned in this blog will go some way in contributing to this change.

Shipping Container Apartments – Constructive vs. Destructive

Australian National University Prefab Container Student Apartments

If you live in or around a major seaport, you have probably seen your fair share of massive ships loaded with containers that contain all sorts of different products. Shipping containers have long been used to transports goods from port to port, but it turns out that they are finding a new lease on life when their transport days are over.

You may know that used shipping containers are being repurposed to create living spaces, which is actually not as ridiculous as it may sound. They are spacious, durable, and easy to convert into a very functional living space. And besides single family housing, shipping container apartments are on the rise in some communities.

One place where this trend has really taken hold is in China, as the influx of migrant workers has had the country scrambling for ways to house all of them. The Chinese have been seeing a major boom in their economy, with the high levels of trade leading to a huge number of shipping containers making their way into the country.

Rather than just have the containers pile up unused, the Chinese government decided to put them to use as housing for the migrant workers. It does not take much to make the containers into a functional living space, and the workers are left with an affordable way to live.

I’m sure that many people will hear about the use of shipping containers as a living space and imagine that the conditions are quite horrid. This is in fact not the case, as the containers are cleaned and made livable before they are put into use.

If you don’t believe that to be the case, you need to look at the shipping container apartment complex that is now being used in Le Havre, France. The boxy look of the apartments looks more like a cool architectural project than anything else, and you really have to get up close to see that it is shipping containers that were used to create the building. The big giveaway when you get close is the doors, as they have retained the original look of the shipping container.

The French version of the shipping container home is a whole lot more luxurious than what the Chinese have, but there is a reason for that. These units are being sold as high-priced apartments, with each of the containers made specifically for that project. The Chinese, on the other hand, wanted to make living spaces that anyone could afford, which is why they went the used container route.

The major benefit of putting shipping containers to use in this way is for the benefits that recycling has in regard to saving the environment. China could have had thousands of these containers just left to rot once their shipping days are over. So, why not do something constructive with them? Constructive versus destructive, you might say. What they have done is kill two birds with one stone, and the success of the project will likely mean that other countries will start to adopt this practice.

 

Ikea Goes Solar in a Big Way

With the global warming crisis, governments and businesses across the world are turning to alternative sources of energy to cut down on their carbon footprint. Solar power is an attractive option to many, due to its ready availability and the potential to generate a steady source of power. The only inhibiting factor is the one time set up and installation cost. Despite government subsidies, uptake of solar power is still slower than predicted. Recently, the Swedish furniture giant IKEA has become one of the first companies to contract a solar panel project without any form of public funding.

How IKEA Aims to Harness Solar Energy

IKEA installed a large solar panel system on one of the roofs of its largest Italian store in Pisa. Over 2700 solar panels were used in the project. These were hoisted onto special mounted frames and assembled on site. It is estimated that solar heat can generate 696.15 kWp of energy, powering all the electricity needs of the store. The amount of energy is estimated to be equivalent to the usage of 800 people, with the overall costs similar to that supplied from the power grid. It is also reported that solar O&M service from Martifer Solar would be part of this project. It is hoped that other businesses would follow in IKEA’s footsteps and set up similar units, especially in the developing world such as China or India.

IKEA has helped boost solar energy as a viable and cheap renewable energy source. Its stores are now selling affordable photovoltaic systems and helping individuals to build solar panels on their roofs. Harnessing power from the sun is likely going to be a popular option with rising energy costs and austerity measures. Significant savings can be made in electricity bills for ordinary homeowners. Technological advances have also meant a fall in the price of solar panels, making them more attractive than a decade ago. Though it takes a few years to recuperate the costs of the panel, this is outweighed by the benefits of long term energy savings.

And if this isn’t enough Ikea has also contracted for a 3.6-megawatt solar project in 7 stores in Australia to help reduce carbon in the atmosphere. When completed this will be one of the largest installations in the word. Ikea’s goal is to be energy independent by 2020.

Conclusion

The IKEA furniture store is investing in alternative energy in a big way by delving into the solar energy market. The company has showcased its commitment to sustainable energy with the installation of the new solar energy systems. The success of these projects will be a significant boost to the local industry and helps to set IKEA as an environmentally responsible business leader in the renewable energy market.

History of Earth Day – a Grassroots Effort

Earth Day 2014

Since tomorrow is Earth Day 2014, I thought it only fitting to write a short history of this special day. What’s the purpose of celebrating Earth Day on April 22 every year? How did it start? These are questions you might be interested in if you are a keen observer of the environment. This celebration is not to be confused with a similar event, the equinoctial Earth Day which is celebrated around March 20 every year.

Well, the idea of the April 22 Earth Day is said to have evolved over a period of 7 years, which began in 1962. For very many years, individuals had been going about the politics of the world while ignoring issues related to the environment they are living in. It was not until November 1962, when the issue was brought into focus, thanks to the founder of this special day, Democratic U. S. Senator Gaylord Nelson (from Wisconsin).

The idea was to convince President Kennedy (who was the United States President at the time), to go on a national environment conservation tour. At the time, Senator Nelson flew to Washington to discuss the tour with Attorney General Robert Kennedy.

Both the President and the Attorney General liked the idea very much. So the President started his 5-day journey across 11 states, with the aim of recognizing Earth Day. This trip was dubbed ”Conservation Tour”, and it happened in the year 1963. However, the tour didn’t succeed in putting the issue onto the limelight of the national political agenda.

But Senator Nelson didn’t give up on the struggle. Instead, he went ahead and talked to 25 more states about the issue. It was evident that the environment was degrading at a fast pace. America’s citizens were noticing this but the political establishment had not. At this time, most politicians simply refused to recognize it.

After the President’s tour, Senator Nelson was even more determined. He still had hope that the issue would somehow find its way onto the National political agenda. Six years later, he set out on a national conservation tour, speaking to people about the idea on a hot summer.

Senator Nelson traveled to champion for environmental conservation while an anti-Vietnam war demonstration was actively being carried out. It was given the name ”teach-ins”, and it had spread in college campuses all across the states. But then Nelson thought this was a good opportunity to organize a huge grassroots protest over the issues that were facing the environment.

Though it was a big gamble because he was taking advantage of the situation to force issues onto the political agenda of the country, his idea was bound to succeed because he was channeling the energy of students to rightful use.

Nelson organized a conference in Seattle in 1969 to announce that there would be a countywide demonstration on behalf of the environment. That’s the time when the announcement started spreading like wild fire. The media was all over it, so the news about the conference was taken serious by the masses.

Because of the grassroots factor, the idea was able to take off successfully this time round. Millions of people showed up on college campuses, secondary schools and communities across the nation. Since that time it has spread to 192 different nations and is celebrated by over 1 billion people each year.

 

Advantages of Solar Chargers – You Got That Sun?

Technology such as computers, tablets and smart phones come with batteries that require charging. Due to their sophisticated functions such as phone calls, Internet access, photography and many others, the devices consume power fast and furious and require frequent charging.

The last thing you want to see when using your iPad is a low battery message. Having a handheld solar charger may come in handy at such a time. These photovoltaic chargers utilize energy from the sun to charge your device.

All modern electronic devices come with their own free battery chargers (USB or wall socket) so one might wonder why you need to go out and purchase an additional charger. After all, if you can buy a smart phone, you most definitely have electricity in your home or office.

First, using solar energy is environmental friendly because it is renewable. It is therefore the ultimate choice for the environmentally conscious individual. These chargers are not tied to the grid which uses mostly coal, natural gas and nuclear power for generating electricity.

Second, a solar charger is portable and can be carried anywhere. You can take it with you to a conference, a camping trip, on vacation or any place. It will work in any location where there is sunlight and it can come in handy when you find yourself far away from a socket. All you need is to expose it to sunlight, connect it to your device and voila, you are good to go.  You do not have to stop working or enjoying yourself even when you find yourself in the remotest of places.

The third advantage is that solar chargers are small and compact and are easy to carry with you wherever you go. You won’t have to lug a lot of extra luggage when you are out communing with nature.

In the long run, solar power will prove to be cheaper for you and the planet since it is a one off investment. If a large number of people were to use solar chargers for all their small devices, imagine the amount of energy and pollution we could save for our planet.

And, it you ever get the hankering to build your own DIY solar charger I’ve included a link on how you can go about doing this.

 

Solar Energy Breakthrough in Australia

Even though China thinks that their scientists are ahead of the rest of the world when it comes to developing solar energy, recent reports have proven otherwise. There is actually an expert team of scientists working hard at the University of New South Wales (NSW) located in Sydney, Australia that recently was able to gain one of the most prestigious awards, within the solar energy field.

A Major Discovery

Professor Wenham worked directly with his UNSW team in order to discover that hydrogen atoms that are capable of effectively countering defects located in silicon cells found within many types of solar panels. That discovery alone led to a vast number of improvements in the design of photovoltaic panels in general. This level of breakthrough was not expected to be discovered and developed for at least another ten years.

What is the Benefit?

The overall process that was defined and developed by Professor Wenham and his team makes it possible for cheap silicon to actually become much better at absorbing light than the very highest quality silicon. It was this discovery that led to this team being recognized publicly for their achievements and awarded an AF Harvey Engineering Research Prize worth $560,000 AU. They were also credited by the President of the Institution of Engineering and Technology (IET) as playing a major role in the overall development and implementation of revolutionary silicon solar cell technology.

Exploring the Actual Results

Thanks to the hydrogenation process that was developed by Professor Wenham’s team, traditional silicon is now able to achieve a high level of performance and efficiency that is equivalent to commercial-grade, high-purity silicon – something that was not possible before their hard work led to this major achievement in science and technology.


What Will Be Done with the Money?

After receiving such a major cash prize, the team has already decided exactly how it will be spent. According to an interview conducted with Professor Wenham, the money will be used to expand a major research area that made it possible for this successful team to win their prize in the first place and gaining 30-percent efficiency on their solar cells.
