If they can make a car go 70mph with an electric motor, why not an electric motor asist for large yachts,(50-60 ft) run off batteries that are charged off a solar array situated on the canopy. Seems like any assist would be worth while considering large yachts go thru 1000's of gallons of fuel. The problem is the speed/drag curve. At speeds most people want to travel, adding low power "assist" propulsion is basically adding more drag. There has been a 40 foot motor yacht that traveled at trawler speeds, totally solar powered. It was not a market success. That was about ten years, I suspect that technology could do a little better now. But it still won't produce a big heavy express cruiser that will plane. If you want a yacht assist that runs off of solar power, the cheapest, best tried and true method is called sails.  I thought sails used wind. Where do you think wind (or all weather, for that matter) comes from? Elves? DSK |

Wind is solar energy, it's the product of the sun heating air. Given that the sun puts down about 800 watts /m2 (1HP/sq yd of surface area) there's plenty of power "available" & it can keep the wind blowing even when in darkness, because of the aggregate huge amounts of energy that are deposited every 24 hrs.

So, you are, in essence, saying that the only component of fossil fuels is sun? |

I'm saying that the power in petroleum based fuel (I guess I should say naturally aged fuel) is just stored solar power from a long time ago. Steve |

Steve Typical response from the village idiot. Do you disagree with my statement that a very small percentage of the wind is a product of the sun heating air, or are you just being childish? |
