Oh this is just cool. I look forward to something like this being commercially available.

Interesting. It will probably be massively expensive when it comes out, if it comes out, but it is an interesting idea none the less.

Did you scroll down? We'd need new LEDs or 4000 kilo weights to make it actually work.

If you scroll down further the 'inventor' admits the concept is fully flawed.

Well, not the concept. The concept works fine. As long as you have LEDs that are way more efficient than the ones that exist today.

LEDs, or an alternative, just like the one published on Slashdot today:

http://news.zdnet.com/2422-13568_22-192842.html (it's a one-minute video, so you know)

I grant you it's only a 2-to-1 improvement against LEDs, but seems they are on the right track.

That might be a distraction to drivers at night. It would ruin their night vision, wouldn't it?

No more so than current street lamps. Or LED traffic lights. The green light on those is uber-bright. I can't look directly at it.

I'm sure something like this *will* be *eventually* available. If not gravity-powered, then with wireless power (go MIT! Get it done!) or something. Anyway, what with OLEDs and nanoscale manufacturing and so on I'm sure we'll have LEDs that are efficient enough within 10 years.

It is 14*C/40*F outside and *pouring* snow...
