I'm wary. Okay, so the point that it subtracts energy from it's surroundings had me confused. I'm not a scientist, I don't claim to be one so I don't know what can or can not happen, but it sounds very far-fetched. Until I see some published article about this, I'm not holding my breath. The idea is interesting in theory, but I often ponder on the future of mankind, so I don't want to "get my hopes up".
