I would like to import it to Africa. Is it available commercially for sell? I would like to import it to Africa.

Verry funny to turn it around for the next night. well, the calculated weight is somewhere around

About as technical as the wind-up torch. But a good idea. For this lamp to work it requires it a person to replace the energy used by returning the weight to the start position.

The weight falls for about 8 hrs, then stops when it reaches bottom. The unit is then inverted so that gravity can again power it by making the weight fall. This isn't a "perpetual motion machine" any more than a wind-up clock is. Dave: This is not a perpetual motion machine. The weight falls for about 8 hrs, then stops when it reaches bottom.

The laws of physics. This thing is a poorly done perpetual motion machine. I'd call it a scam, but I think the poor designer just never paid enough attention in Phys 101. It's sad that the people judging the contest obviously didn't either. You know what else will turn it off? The laws of physics. This thing is a poorly done perpetual motion machine.

So the question is how can it be turned off if we don't need it. Is there a power switch or anything, its written it uses the concept of an hour glass..
