Reinventing The Wheel.

[sandyRoe]

A ship with 'sails' to help reduce it's carbon footprint has just set sail on a voyage from Singapore to Brazil.
Nothing new under the sun, what?

[Khandro]

In a village near to me, a guy has a sawmill powered by a waterwheel on a small stream. - nothing new there ?

but instead of it being a direct drive the wheel produces electricity via a dynamo, alternator, or whatever, with storage system which then powers not only the saws but his house as well.

Cool?

This is an exciting innovation which looks to be able to make a difference. It is great to be British, and who knows where it may lead?.
