« New Solar Hydrogen Production Method | Main | Brown Will Become More Green »

February 19, 2006



The formatting for the section starting with the bullets in the Gen 2 section and going to the "SolFocus competitors are Sunball..." line is way right indented and most of it is off the screen, at least on my browser.

Does it looked screwed up to anyone else?


(I'm seeing the same typesetting problems)

I was under the impression that the big challenge in solar collectors was not the cost of the collector array, but of the tracking hardware. I didn't see a mention in the article regarding whether they have addressed this problem.

I still believe the tech with the highest potential is in solid state systems, like holographic mirrors and lenses, which have no need to track the sun. One variation I found very interesting was a film that would redirect sunlight incident on a window at certain angles (think: 5pm or noonday sun glaring through the window) toward the ceiling. The biggest downside is that current prices dwarf that of tracking systems.

I don't have any formating problems that I can see when I view my blog. Anyone else having a problem?

As far as the tracking hardware, their only mention was "there have been a number of cost and reliability improvements, and trackers are commonly used in large field-based installations of even flat-plate PV....However, improved system features including lightweight trackers and recent technological advancements are allowing CPV to be mounted on rooftops where it can generate 10-100 kilowatts of electricity at many commercial sites or 1 MW or more on large industrial rooftops."

They havn't had much field experience, so it is too early to tell if they are having problems. They claim to have run reliability tests on all equipment, but from the context of that statement it is hard to tell if that was for modules or for the whole system.

I'm having the format problems too (viewing with Firefox).
This kind of idea seems a likely way forward to me. I'd previously wondered whether it would be possible to have cheap glass 'light-catchers' that sent most daylight via optic cables to a combined in-house PV unit. That way as much light as is available could be relatively easily captured and the light-electricity unit could be upgraded as more-efficient PV materials are created. Such a system would have the added advantage of being able to transfer light directly to luminaires (increasing efficiency).
The lack of sunlight in countries such as mine (U.K) could also be countered by the purchase of more fairly cheap, entirely glass panels. God knows I don't know how solar is ever going to be part of the mix here otherwise!


What about a liquid lens? Could be continuously adjusted.


I'm seeing that formatting problem too.

I am aware the problem still exists, typepad is trying to figure our what I did wrong, their first fix didn't help.


Sunflower uses glass mirrors, not plastic fresnel lenses. They agree that plastic fresnel is inferior.

Nick is right and I have changed the text to indicate this. There are just too many details that my old mind has trouble remembering and I really don't have time to check everything out. Thanks for keeping me honest.

It's a giant leap to say that Sunflower, IAS and Sunball are in production and way ahead of Solfucus. (Amonix, on the other hand, has been a major player for many years and is in production.) All are still in the testing stage and are, at best, in pre-production stage.


It seems to me that dealing with all the excess heat on the cells would be an opportunity to heat some hot water for the building as well. Heat the water, cool the cells and the costs can be defrayed even more, as well as increasing the life of the cells.

I was searching for some informaton about the optical and magnetic properties and solutions and i am glad that i have found your site.


I would like to buy stock in your company and promote its products in the Negev town of Arad in Israel. Please advise

I looked at all the glasses, but none seem to match your description.
(Your description was very good, by the way - I understood it!) :-)

If you can't locate the ones you want, you could try contacting the
