Re: solar powered boat?

i cant wait for the ceramic engines to come along. no oil no coolant. after the oil companies release all of the patents that they have bought up over the last 50 years. maybe alternative fueled engines will come out.
as for solar, its ok, my neighbor where my cruiser is moored has solar everything in his house. if he goes away for a week, when he comes back....no joke....the water in the toilet will burn ya. sw florida sun is hot, thats the only problem. there is no way to controll the creeping thermal properties of that energy. unless you have substantial coolers as to say. but its great to keep the batteries charged up.
the problem with electic outboards is the batt gasses they give off. top that with charging as well as using them at the same time then the amount of gasses produced goes way up. and that my friend is worse than any gasoline explosion. not to mention the acid flying everywhere.
bio diesel is the next big thing i think though. as ive installed the system on three newer ford trucks so far. smells like mc donalds chuggin along. but its better than gettin chocked out by regular diesel smog right?
plus has anyone seen the sterling steam engine for gensets? those use a fuel burner to heat hydrogen instead of steam to say. the hydrogen is recycled from the hot side to the cold side back and forth. it uses a wobble shaft to transfer the energy to about 55kw of power. The advantages of a stirling marine power generator include high reliability with low maintenance, near silent operation with no vibration, extremely clean emissions with no odor and the ability to run on a variety of alternative and renewable fuels including hydrogen, alcohol, gasohol, biomass fuels, gasoline and diesel fuels, propane and solar power. so there ya go. they have stirling engines that run off the heat produced by the plam of your hand!!! so just having that goin is like using your big gas hog engines to charge the batteries.
you could use that to keep everything running clean and purty. not to mention almost near silent. with very low cost and no exta hours on that inboard. or loud as* genset....
now if you take that principle..add 7 cylinders to it. there you go a very low emmission, very low maintnence provided they have one liftime lubricant inside the engine, no byproduct of the combustion process is ever introduced into the rotating assy. therefore making the life of these engines so great. that they would last almost forever. they would be expensive. but after the initial fork over of lots of cash they would be cheap, low maint., and enviromentally sound. so there is alot of r&d goin on its just not public cause the patents would be bought out before they even went to development.

Re: solar powered boat?

I'm still waiting for the evil auto manufacturers to release the patents on the carburetors that allow internal combustion engines to run on water!!! Remember that comspiracy theory?

Come on - if ANYONE had the technology to make any of this stuff work they'd be producing and selling it to the entire world. What's the profit motive in buying up these patents and sitting on them? If the oil companies had these patents they'd transition their business from oil to the new-tech engines. Profit is profit - why would they care where it is derived?

It's fun to read about this stuff in Popular Mechanics but you'll know it's here and for real when you're reading about it in the Wall Street Journal.

Re: solar powered boat?

Surprised nobody has brought up Sterling cycle engines using a parabolic mirror solar collector for heat and the water for cooling.

Nice big difference in temperature (what runs the Sterling cycle) depending on strength of the sun, size of the collector and temp of surface water.

No "fuel" at all, no pollution at all (unless you consider discharge of warmed water pollution). Not very powerful or very "efficient", but the energy is free.

Re: solar powered boat?

Another interesting point electric and steam power develope their torque at 0 rpm.And as motor speed decreases torque goes up.My little 5 hp GEM electric car can chirp the tires off the line and that is with a gentle start progammed in the controller.As I undrestand it a 7 hp reprogammed can smoke the tires.

Interesting, Spike. The Sterling also develops max torque at 0 rpm.
