Unfortunately, a bunch of the claims in the article are just not true. The amount of energy available in the UV spectrum is extremely small compared to the amount in the visible range. There are a couple of nice charts here: http://en.wikipedia.org/wiki/Solar_radiation , especially the one in the "climate effect" section. The area under a section of the curve is proportional to the amount of incident energy in that wavelength range.
There is no way this can harness 500 times the light of a typical solar cell. Most current devices are around 10% efficient or more, which means they convert 10% of ALL of the incident solar radiation (including UV and infrared) to electricity. The record so far is about 40%. So there is no way this could get close to even 10 times as much conversion as a typical cell, or double the best proven technology. Could he have developed a more efficient design for a solar device? Maybe. Could the design be easier to install? Maybe. Is there something groundbreaking and new here that will completely change the solar industry on its own? I doubt it. Is it cool that this was done by a 12-year old? Sure, assuming it's true, and it still would be if he was a college student. I think that's the nice part of the story, even though the technological claims are questionable. -- Rich ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[email protected]> Sent: Tuesday, September 23, 2008 11:10 AM Subject: Re: [SustainableTompkins] inspiring solar tech news > Thanks Elan. > > It seem such a basic concept when you think about it.? > > And yet?it waited for a 12 year old to think there might be other parts?of > the light spectrum that could be utilized.
