Dr. Jon Major, a researcher at Liverpool University has recently made the discovery that the chemical used to make tofu, and bath salts, could also be used to replace one of the most toxic substances, namely cadmium chloride, that are used to manufacture solar cells. Using salts to replace cadmium chloride in solar cell production would also make them much cheaper. His study was published in the journal Nature.

Rooftop Mounted Wind Turbines That Make Homes Self-Sufficient

When it comes to renewable energy, wind turbines are certainly one of the greener and more sustainable options. Their biggest drawbacks is that they have to be large to produce enough energy, and that they make a lot of noise, which is why they haven’t yet been widely adopted by homeowners. However, The Archimedes, a Holland-based renewable energy start-up is currently working on a solution to this problem. They are designing a wind turbine small enough to be mounted on the roof of a typical home, but which is still highly efficient at converting wind to energy and does so nearly soundlessly.

The photovoltaic technology is frequently used to obtain energy these days. Since it was discovered in the 19th century that it is possible to get energy from sunlight, the ways of harnessing solar energy went through many different stages. The first prototype of solar cells was, for example, used to provide the satellite Vanguard I with energy in 1958 and the technology has been used in this area ever since.

Energy Harnessed From Waves Could be on the Horizon

A team of researchers at UC Berkeley is developing a hydraulic seafloor ‘carpet’ that could be used to harvest the energy of ocean waves and convert it to usable clean energy. Since waves are constant, as opposed to sun and wind, this could prove a viable source of carbon-free energy for coastal regions. Wave energy is considered a huge potential source of renewable energy, but the systems for harnessing it are still very underdeveloped. Since there has been a rise in population in coastal cities this form of energy harvesting could prove a great, and, more importantly, clean source of renewable energy.

This Week in Energy News – February 22, 2013

This week in Jetson Green Energy News, New York City is preparing for the next big storm and a California land rush could result in alternative energy providing the state with 100% of its power needs.

New York City East River Blueway Plan

Proposed: Four Miles of Manhattan’s East River to be Redeveloped with Storm Barrier

WXY Architecture + Urban Design, working with local officials and community groups, has developed the East River Blueway Plan to redevelop a stretch of Manhattan’s waterways to combat storm water surge, calling “for the creation of wetlands, parks, bicycle and pedestrian pathways and bridges, and the redevelopment of a disused beach under the Brooklyn Bridge.”
