Wow, it is less than a week away. Yahoo Green had a nice article about starting school. They cover everything from keeping Swine Flu in perspective to healthy lunches, recess, backpacks, vaccinations, and references to other good sources of information.

On August 4th I wrote about a solar company claiming 800x improvement on the power generated and made some points about how that was attained. The article is here "Solar Cell Power Production is Increased 800x?!?".

This article is about a breakthrough regarding the actual solar cell as normally exposed to light. The world record conversion efficiency was accepted by the scientific journal - Progress in Photovoltaics (PIP), which offers a forum for reporting advances in the PV industry and independently tested by Fraunhofer Institute for Solar Energy Systems ISE in Germany.

This is a new world record conversion efficiency of 15.6% on a commercial-grade multi-crystalline silicon PV module. This conversion efficiency surpasses the previous record of 15.5% set by Sandia National Labs 15 years ago.

You can see that this is significant, but without a breakthrough, we are very much at the limit for current PV technology. This increase took 15 years to achieve and represents a 0.1% increase in efficiency.

You can see why I was so quick to point out that in the previous article claiming 800x, it was not the solar cell but the light delivery that was actually increased.

This is not a new project, but a recent project. What is new is that they just crossed the Thames river with this machine! There is a great deal of information and photos at their website.

The Korea Advanced Institute of Science and Technology feels that an electric vehicle would perform better without batteries. As this is not a new idea, but an idea to get back to basics, they might be on to something. I remember as a kid, the buses in San Francisco had these long arms that reached up to wires overhead and asking my dad what they were. So we have had electric public transit for quite some time as this was over 30 years ago.
