How a Seventh Grader May Have Just Upped the Solar Ante

Suffice it to say it won’t be surprising when the name William Yuan finds its place among the luminaries of solar energy research and development.  What makes this so remarkable is that he is in seventh grade, but with an intellect equal to those many decades his senior.  What Yuan has done is develop a 3D nanotube-based solar cell (originally invented by a team at the Georgia Tech Research Institute in 2004) capable of absorbing a much wider spectrum of light, while yielding 500 times the absorption of standard solar cells and nine times more than today’s most sophisticated 3D cells, a breakthrough for which he received a $25,000 scholarship from the Davidson Institute in Reno, Nevada.  To experts in the field, the 3D solar cell may indeed hold the key to the gain in efficiency that solar technology must make before it can become the truly viable alternative to fossil fuels, so it is exciting to imagine what breakthroughs like this may bring.  The only downside it may have however, are the long term environmental effects associated with both cadmium (a toxic component common to many solar cells) and nano tubes, which many fear could lead to problems similar to if not worse than those of asbestos, but if such drawbacks can be effectively addressed, the future of nanosolar technology may be that much brighter, thanks to the mind of William Yuan.

Ford to Generate Electricity…from Paint!

If ever there was a time to stand in awe of the world of science, it is now, in this burgeoning age of clean tech geniuses coming up with fascinating (if not mind-blowing) solutions to the energy and environmental challenges with which we’re faced.  One such remarkable solution is being launched by U.S. automaker Ford, whose own team of such geniuses have come up with a method of harnessing the electricity-generating potential of VOC’s in autobody paint.  To be launched at their Oakville, Ontario plant, the process called Fumes-to-Fuel involves the sequestration of VOC’s in a 2,000 gallon vat of carbon beads, where they are absorbed.  The carbon beads are then processed themselves, to release the VOC’s for conversion into fuel for a 300 KW fuel cell that will power the plant itself.  According to Ford, the electricity generated by the fuel cell is enough to power about 150 homes, and the process will result in an 88% reduction of carbon dioxide and elimination of nitrogen oxide, two negative aspects inherent in autobody painting.

By utilizing VOC’s for good, Ford has set the stage for other automakers to take up a similarly progressive clean tech mantle.  Reducing noxious gases and CO2 within their plants, and converting paint fumes to power their own facilities, are no small feats, however the automaker still must strive to quickly develop super-efficient vehicles in the same progressive vein.  In fact, it must do so to survive, as Japanese and German (VW and BMW) automakers are already making strides in alternative fuels and fuel efficiency.  Nonetheless, Ford’s Fumes-to-Fuel program is surely a sign of things to come, as more and more companies push the envelope, and emerge with the right solutions to our energy dependent world.

A Green Home Comes to Unst

No one said building a carbon-neutral house would be easy, so to build one in the often harsh conditions of Unst (100 mph winter winds!), the northern most island in the Shetlands, is a remarkable achievement indeed. Having retired from their former lives in Wiltshire, in Southwestern England, Michael and Dorothy Rea set out to design and build a house on the island that would be completely self sufficient or “off the grid”, incorporating renewable energy principles not uncommon to many of the innovative people inhabiting some of the remote islands off the Scottish coast. These include solar panels and wind turbines for power generation, a natural underfloor ventilation and heating system, a hydroponic greenhouse for vegetables, extensive reuse of rainwater throughout the house, and an effort to run the lights on no more than 100 Watts, through the aid of LED bulbs. The University of Delaware is even refitting an electric engine into a Toyota Yaris, which will be re-charged from power provided by the house itself.

It is no surprise that the house is fast becoming famous within the green building world, even garnering the attention of the Chinese Government for their planned eco-community in Guangzhou. With their Zero Carbon House Project, the Rea’s are demonstrating that homes can be built to have no negative emissions, and their website offers a number of ways to follow their progress, as well as many resources to learn about green building, alternative energy principles and technologies, and the many notable sponsors who have assisted in the process. You can even contact the Rea’s directly, so they seem to be making every effort to maintain a high level of transparency throughout the project. As Dorothy Rea exclaimed to the Guardian, “If we can do this here, anyone can do it anywhere”, so let’s hope that more homeowners take the sentiment to heart, and aspire to build their own zero-emission homes in communities throughout the world.
