Efficiency games

New Solar Balloon Creates 400 Times More Energy Than The Average Solar Cell

I'll share because it looks and sounds fun, but the claims may need an eyebrow crank.

Concentrated solar is definitely a good prospect going forward - existing setups suffer from requiring many acres of flat land - but this one looks very intriguing, and potentially (at 1$ per watt according to their website) a much cheaper alternative form.
Interesting that the PR all claims '400 times more' yet their own FAQ's claim '300 to 400 times more'.
Like you though, I have to crank my eyebrow at such a claim, especially as their technology pages suggest that they are going to have to water cool the photovoltaic cells. Keeping water cool enough to cool down something inside something else exposed to potential temperatures of several 100 degrees sounds quite a challenge!

Definitely worth keeping half an eye on though.
