CleanTech 100
Today’s The Guardian / Library House CleanTech 100 supplement (technology Guardian) contains several short pieces from me. CleanTech 100 is a list of 100 clean technology companies selected for their potential for future growth and beneficial impact on the environment. Follow the links below for more.
Odersun – Awarded first place in CleanTech 100
German company Odersun makes thin-film solar cells based on copper, indium, and sulphur using a worldwide patented process. Though not as energy efficient as silicon, it’s cheaper and can be formed into virtually any size or power.
An ultra-quiet wind turbine which combines good looks with high energy efficiency. It’s 20%-40% more efficient than an ordinary turbine in urban locations.
Quantasol (no link)
A spinout from Imperial College, Quantasol is taking solar cells to a new level of efficiency. By tailoring structures on the nano-scale, the gallium arsenide cells have efficiencies of 27% (silicon cells are around 15%).
There are several home energy monitoring devices available but none that aspire to being the “iPod of cleantech”. In January 2009, Onzo is launching products with an emphasis on a “stylish modern design” to give consumers the information they need about home electricity use.
