I pitched a couple of bucks towards the project because I saw several other implementations of the exact same ideas work at Burning Man... a pathway that was lit by solar power, reacted to people walking on it, and involved interesting materials, science, electronics, and human interaction. And two of those projects survived the highly alkaline desert environment, and went back to Burning Man several times. So yeah... the technology works. It's not magic like cold fusion. But like I said in my other comment, I always saw this as a pedestrian thing, maybe with limited use on non-commercial-vehicle roads (like bike paths, parking lots, etc.). So yeah. I have seen similar projects work, and work pretty well. I was hoping that instead of an "artist" building an "art installation", something with proper funding would come up with something more resilient and commercially viable. I still hold that hope. Hell... how long has Moller been at it?
