Alternative power/recharging source?

[Ed Montgomery]

Came across this rather amazing item the other day,
and instantly thought this might be a very, very
useful power/recharging mechanism for the XO...

A lamp powered by gravity producing 40 watts over 4
hours...using gravity! :-) (Consider the XO using
about 2 watts...)
Not affected by weather/season/time of day (e.g.
solar/wind) or behaviour (animal/cow) or location,
etc.  An unlimited power source available anywhere
anytime!

Could this mechanism (which apparently is more durable
than the LEDs in the lamp!) be modified to power
and/or recharge the XO batteries, etc.?

A preliminary article about the gravity lamp can be
found here (from Virginia Tech):
