A solar boat is sailing around the Mediterranean to promote renewable energy and ocean conservation. Powered by light energy from our star. Yes, it's just one boat but it's the symbolic message that's important in this case (it is one cool looking boat anyway).
As I've wished aloud, it would be great if the Gulf disaster became the impetus to wean ourselves from oil. Although it doesn't look promising as the US Congress and the Obama administration seem incapable of creating any clean energy legislation without some major capitulation to the Money -- the petroleum and fossil fuel corporations and lobbyists. What will it take for them to see the light?
A picture of the sun boat and a short article about it from the Clean Technica site is here:
