Re: LCD lighting

Speaking of Real Goods, I just stopped by their Solar Living Center in
Hopland, CA on Monday.  If you haven't been and it isn't too far from where
you live it's definitely worth the visit.  (Especially if you are like me
still coming up to speed on implementing stuff like solar power and the
They run off of their solar and wind power and sell back their extra power.
also have various exhibits where you can play with solar panels and pumps
the like.  Really quite an impressive place.

Anyway, speaking of LCD lighting it reminded me of LED lighting.
In general I think the light is a bit blue for me, but we got this very
cool flashlight while at real goods.  The light itself is an led light and
the inside is magnite and a coil and a capaciter.  You generate power
by shaking the flashlight and the light lasts (at a readable level) for a
5-10 minutes and overall for probably about 20 minutes.

Anyway, gotta run now, but I thought I should send this out.
