Light a candle in the darkness

As most of us know there have been significant improvements in  LED’s efficiency the last few years and now some of our basic needs are starting to be met by them. One of these is light without sunshine, batteries or water wheels. The Deciwatt gravity light uses a pulley system and a weight. The weight can be pretty much of anything – sack of sand or bag of rocks. Think power outage, camping or a romantic interlude. Soon as this becomes available I’m in.
