Comments on: Old solar tech back in limelight

Start-ups focus on an old technique of concentrating sunlight to make more cost-efficient photovoltaic panels.

You Missed One - Green and Gold Energy in Australia

Fresnel lens concentrator. Currently in production (as far as I can
tell from their web site).

Interesting invention

Neat product, but for the people who did not follow the "New Inventors" show the website is a little lacking.

They have a pretty large following and I am sure someone would be willing build a more usable website for cheap or free.

After some digging I found more info on the "New Inevntors" website here: http://www.abc.net.au/newinventors/txt/s1487858.htm

The "Watch broadband video" link explains how it works.

a technology that overcomes limitations of PV

HI - two things -
1 - check out Stirling Energy Systems in Phoenix, AZ - utilizing the Stirling engine, limitations of photo V cells appears to have been overcome, effectively and efficiently...SoCal Edison has bought in big time!
2 - I want to work in a job that serves the solar energy field, potentially from the publishing perspective (editorial discussing the various competing technologies for the engineering and applications personnel serving solar ingenuity) and I'm curious if you can turn me onto some of the more reliable, reputable publications &/or publishers serving the field. Also, a research firm may be providing insights to companies either investing in or evaluating applying solar/renewable resource solutions.

thanks - John

Missed another one- Sopogy

I found another one. Sopogy, out of Honolulu, HI. They use concentrators to create power. This focus on alternative technologies is great and with the climate issues its wonderful to see the venture capitalist investing in these solutions.
