Solar Power Boat

They covered the craft, made from black carbon fiber, with 150 square feet of solar cells to power it at up to 35 mph.

Great idea. Now lets solve our problem in practical terms.

I think that this is a good thing, like the Tesla. Why not power a boat on solar energy? Maybe they will power some huge ships this way. I was thinking that a large container ship could make it's way across the ocean with wind, then use solar powered electric motors to get into port.
Why wouldn't that work?

That is probably exactly the way it will happen ... back to the 19th century. |

It's hard to keep a boat moving through the water because there is so much mass to push aside with the bow. My friend spends a lot of time on the water in a 26'. He says he averages 1 1/2 miles to the gallon.
I doubt that an electric motor could move anything larger than a kayak for a distance.

A solar-powered boat is called a sailboat.

| Solar is a good backup for when the wind ISN'T blowing. |

Container ships of those size don't need their 120,000 horsepower engines just for speed, that kind of torque is also usefull when manouvering in port. You'd need a hell of alot of solar panels, or some bloody huge masts and sails, let alone trying to keep service speeds of 27 to 32 knots, which the industry will want to maintain for reasons of efficiency. My bet is we'll see these vessels having their diesel plants converted to Nuclear steam plants, using much of the plant design specifications already in most LNG vessels, that burn the boil-off gas from their cargoes to produce steam.
Also, the hull design is completely wrong for sailpower.

That's why they are now starting to use those kites that help pull these ships along in the direction of the wind. It's not really sailing but it helps. |

I mentioned this one in a thread back in 2006;
solarsailor
It is a bit on the pricey side, but at least it is in commercial production.
I know some Swedish boat manufacturer is coming out with some recreational boats run with photovoltaics/batteries, early this autum, but unfortunately I haven't got their name yet. (They were shown on a video clip from an expo but no company name etc mentioned.)

Sorry to be a bit off-topic, but why do they use the boil-off gas to make steam and drive a steam plant?
You can use boil-off gas in the engine in addition to fuel oil (dual fuel). A ship engine should provide the ship with all the waste heat required for making steam and hot water for the crew. |

Actually if you stay below displacement speed it's pretty easy to move a boat. I can push a 30 foot boat through the water much more easily than even a small car on land. Working in a marina gives me daily opportunity to do so.

Nice thing about displacement hulled boats is they usually have lots of room for batteries and the extra weight doesn't affect the range very much, as long as you aren't trying to go fast.

MOST of our oil goes to cars so there's no point in throwing 80% of our efforts into 20% of our problems.
That and also
Contrary to popular belief ships are actually VERY energy efficient.
The cost of fuel relative to total cost of running a ship is very small unlike say the trucking industry.
BTW container ships must have open space above deck so the gantry cranes can load + unload containers. Where are you going to put the solar panels?  |

ding ding ding...
Lets not forget what these things are hauling to begin with! Mostly Chinese junk for the wal mart consumer. How about we build the crap locally and save a lot in transportation.
Problem solved dudes...

Personally I see it as a good way to get myself a cheap feed.
Once you get out on the water you catch more and bigger than from the shore....at least where I am.
So in the macro view it might not be so important but on an individual level it can be.

Big ships have to be nuclear like big aircraft carriers.
With the end of crude the big supertankers could be used as a nuclear cargo boats, and For small cargos we can use sails like in the 18 century and solar power.
the same for small fishing boats.
but i supose that strategic sectors can use biofuels . |
