    xns, I know that. This thread got out of hand, I was simply telling them what is true and because of that I am an ignorant moron. I never even wanted to use moon powered solar panels ,if you read the whole forum, I was proving they exist.

    proving it to who?

    for getting eco-friendly renewable power sources to power a seastead was “solved” long time ago. In the beginning diesel generators combined with PV solar panels and wind generators and in the long run hydrogen The new guys should read the old threads and get up to date with what was previously discussed and agreed here.

    Well it’s not that easy to find the old threads there are so many.

    Hmmm. You have to keep it aligned, though – not easy to do when floating in the ocean. Also, you can’t convert it all into energy; you could maybe get 10-20% efficiency, and you’re limited to an absolute maximum of 50% by the… Carnot efficiency? I’m not sure it would be worth doing more than some simple solar cells…

    If only we could get our hands on this…http://www.youtube.com/watch?v=TtzRAjW6KO0

    With a few elaberations we could convert all that into energy. There are other uses too like even a weapon, and they can be made pretty easily with the right supplies.

    You still need the same area, though. That it has to be lined up with the sun counts against it, since you have to track the sun to actually get some energy.

    For starting fires we have lighters, for weapons we have AK-47′s, for melting metals we have methane. I can’t see a future for concentrated solar thermal on seasteads…

    Well it has other uses too. Like a weapon, great for starting fires as you have seen, melting metal. Plus even though the thing must aligned with the sun, 5,000 suns is better than one.

    AKs dont have to be our only weapons I mean wecould set a whole boat of pirates on fire with this. Plus finding the sun is not hard to do and no that hard to line this up with the sun either. I know the pirates would need to be coming in the direction of where the sun is but if they are we got a nice way of getting rid of them.

    How do you intend to use it as a weapon? Unless you can change the focus of the dish, you can’t alter the point of maximum intensity, and since it has to be aligned with the sun, you’re very very restricted in where the dish can be pointed. It makes a lousy weapon system. If you have a steam turbine, though, you can use it for electricity generation.

    Yeah I know I wanted to use this for electricity.

    I disagree strongly. I see solar thermal as being the only viable energy system for seasteads. Molten salt solar thermal systems are far more efficient than photovoltaic systems, since the energy storage mechanism is built right in. No need for batteries or anything else.

    Also, there are multiple mechanisms for tracking the sun, and to be fair the seasteads are not going to be rolling around like crazy. If they are then nobody is going to be living there so we won’t have a need for large capacity energy systems. Either the seastead itself will be rock-steady in the water, or there will be a calm area encircled by a breakwater. Either way I don’t see tracking the sun, or stability as a whole, as a problem.

    Solar thermal systems are also much cheaper than photovoltaic systems, and the mirrors don’t need to be regularly replaced…unlike photovoltaic panels which wear out over time.

    Sandia National Laboratories National Solar Thermal Test Facility

    The current world record holder for the solar-to-grid conversion efficiency record is a solar thermal system: link

    Plus, it is the only solar system that can provide baseload electricity: 24-hours of solar power

    I see concentrated solar power with molten salt energy storage as the only viable energy system for seasteads, with some wind- and water-based systems as supplemental.

    A bicycle powered generator could help generater personal power for lights and tv but not to power the whole seastead. It would be used to help take some pressure off the solar cells and wind/water turbines.

    Bicycles could also be used to do laundry with to help keep even more electrical power from being used.

    TV’s on the seastead could also be powered with a bicycle generator

    Bicycle powered tools are also a possibility

    Here is a good site for wind turbines
