Re: Alternative to Solar

Why be a pessimist, when the mechanical problem was solved some 60 years ago (self-winding wristwatches) and updated more than a decade ago with Seiko's "Kinetic" series, which use a small dynamo to generate electricity to power their watches the same way?

Bobbing, rocking, rolling, all could easily turn a dynamo and generate electricity. How much motion, how much bulk, how much cost, how much output, these are all trivial variables compared to the larger question of a tiny niche market.

There are much larger projects to use ocean tidal/wave motions to turn dynamos in a similar way. of course, they're on a much larger scale and unlike boats, those locations are chosen to be in motion rather than at calm rest.
