Author Topic: Gravity-powered lamp Daniel Butler I'm a Singapore where is my boat Member # 1689 posted                       Oh this is just cool. I look forward to something like this being commercially available. Registered: Jul 2005  |  IP: Logged Sean First Tenor Member # 2010 posted                       Interesting. It will probably be massively expensive when it comes out, if it comes out, but it is an interesting idea none the less. -------------------- "Kosh, I'd like to introduce you to our Resident schmuck and his side kick Kick Me."-Ritten "Fighting for peace is like screwing for virginity". -George Carlin Registered: Jul 2007  |  IP: Logged bX Stopped.

It would ruin their night vision, wouldn't it? -------------------- "Kosh, I'd like to introduce you to our Resident schmuck and his side kick Kick Me."-Ritten "Fighting for peace is like screwing for virginity". -George Carlin Registered: Jul 2007  |  IP: Logged Fabrux Epic Member Member # 71 posted                       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 haul cardboard and cardboard accessories Registered: Mar 1999  |  IP: Logged Daniel Butler I'm a Singapore where is my boat Member # 1689 posted                       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...
