    Wind Power Udon?

    My gut tells me we don't have enough wind here to use this.

    Anyone know how much wind a turbine would need to supply a house with Aircon, ect?

    How would you determine what the average winds are here?

    I did locate a solar manufactor in Korat, but unfortunately they don't have a distributor in Thailand.

    There site mentioned selling power back to the electric compnay I know about this in the states but have not heard of it in Thailand.

    If you had the largest wind turbine available on the planet in the windiest part of the globe, you might power a 13,000 BTU a/c enough to drop the temp of an avereage size room a few degrees below ambient. You might power a microwave oven to bake a single potato in just under six months.

    This brings back images of Gilligan peddling a bicycle to power Skipper's television. Fantasy.

    Udon is windy (regularly) a few weeks per year, usually just before the rains. It's not enough to justify the cost of a wind turbine and batteries. Udon electric company does all it can just to keep power on, nevermind having users add power back into the grid.

    Actually if you were to have enough wind to drive a Siemens SWT-3.6-107 Wind Turbine you would generate 3600 Kilowatts per hout which would power at least three 13,000 btu air condition units.
    Of course, it would take about 999 years to get ur investment back.

    Don't want to burst your bubble.

    However, TD can't even figure out a roof fan.

    I've heard those windmill things can't even power a hairdryer.

    You might get enough wind to generate something on a twelve volt scale. Good for emergency lighting and powering small inverters. In any event is is going to be a large investment, just to see if it works. Try Googling 'Rutland wind charger' to get on to their website. They will be able to give you an idea of how much wind you will need to generate how many amps. To get anything like mains power, you are talking about living on the top of a high hill and having a 'mill' that has a vast wingspan. Good luck to you though, it is a nice idea.

    B and Q Wind Turbines and Solar - Wind

    here in the uk you can buy 240 volt /1kw wind gennys off the shelf

    do i get a green?

    Those little wind jennies we used on boats kept a trickle going enough to keep the batteries up to scratch.

    At least yes.
    More likely, it would be able to power 1000++ of them.

    Luckily Europe has nuclear power plants for feeding those huge outdoor fans

    And it might provide air conditioning for a very, very small turtle.

    The biggest problem with using wind power to run a/c is that on a cold and windy day you don't need the power, while on a windless, sunny and hot day, the power (wind) will not be there.

    Hence you have to factor in a hell of a battery storage system as well. Big $$!

    If you are serious about being green - look into solar power instead - at least that will give you the power when you really need it.
    Any error in tact, fact or spelling is purely due to transmissional errors...

    There is someone over here developing wind generators. In some parts of the country there is potential. From memory a 4K unit will be about 50K, which isn't that much. But if you're thinking about renewable energy for electricity, best to try and live without air con.

    Unfortunately , you'll still need the battery farm and the inverter.
    And it will be a lot of batteries if you want to get some real power out of it, or if you need power when sun has set.
    Solar power panels are still expensive - you'll need many.

    You can get rid of the storage cost if you sell your produced energy to a power distribution company, and then buy from them when you need power.
    The voices in my head are mostly kind, I also like the music.

    Really, so the others on this thread doubting the benefits of wind turbines are spouting poop then?

    Green for you.

    Apparently there is technology on the horizon that will allow solar panels to be printed from bubble jet printers. They will be 1% the cost of present panels with 70% the efficiency.

    This is the way to go, but I can't see Thailand doing this for a while. It's a shame they don't offer incentives for switching to solar, it could help develop an export industry.

    Can you provide a link to more information on this claim please?

    Current best prices are First solars 1.29$ per watt with 9% efficiency. there stock price has gone up like a zillion per cent in the last year.

    Please tell the name of the company who can print these!

    Sorry I can't give anymore info, actually I think you know more than I do! It's just something I read and am passing on. However if they are already making them with 9% efficiency, then I'm guessing there is potential for this to grow quickly. Technology moves fast, only 10 yrs ago a computer with 64K RAM was considered quick.

    When I say 70% efficiency, I mean 70% as efficient as present panels.

    Not neccesarily, since

    Exactly - and I believe Thailand actually has such a system in place.

    regarding batterys, they have to be deep cycle
    one solution is to use second hand fork lift batterys
    each one has a voltage of 55 volts and huge amperage , so once fully charged -last a long time
    you still need to invert the current to ac/50hertz though
    although you could still run some things on dc though

    From EC-ASEAN Green Independent Power Producers Network / page 3

    In Thailand, the Small Power Producers (SPPs) program was introduced in the early 1990s and is designed to promote grid-connected electricity generation from renewable energy and cogeneration. A flexible power purchase agreement has been introduced (firm and non-firm) to respond to the technical limitations of renewable energy technologies. Power purchase price is based on the utility’s avoided costs.

    In 2002, Thailand introduced a new framework that promotes small-scale renewable electricity generation known as Very Small Renewable Energy Power Producers (VSREPP). A VSREPP is defined as a generator with his own generating unit, whose power generating process utilizes renewable energy sources, agricultural and industrial wastes and residues, or by-product steam, and who sells no more than 1 MW of electrical power directly to a distribution utility. The VSREPP regulations allow for net metering arrangements and streamlined interconnection process and requirements so as to minimize the costs of connecting a VSREPP to the distribution systems. Generators with net generation can generate income by selling electricity to the distribution utilities at the latter’s avoided costs (the wholesale price that the distribution utilities pay to EGAT for bulk electricity). The main targets of the VSREPP Program are pig farms and food processing industries.

    Well for what it's worth guys I do know windpower does work. I came from the Palm Springs area where there are numerous wind farms, selling electricity to the grid. But those are huge machines. They are located in a area that is a virtual wind tunnel, a mountian pass into a desert. They work there but it is a definte windy area.

    I don't see those kinds of winds here. Cost prohibitive I would think so. These wind farms exist because of tax rebates to investors as well as funds paid from power generation.

    So it is doable. But. I don't think so here.

    To be honest it is not today I'm thinking about electricity is in fact cheap here compared to a lot of areas. I don't know what that will be tomorrow. Just thinking ahead a bit. Not trying to save the planet.

    I did find a site that talked about producing solar cells in much faster method located in Vhina apparently sate of art at the moment. so there are advances, but still very cost prohibitive still yet.

    Never hurts to ask only hurts to pull out the wallet

    Nanosolar Appears to have the technology that people are talking about. They are supposed to be shipping thier first commercial order.
    I hope someone comes up with somethig better than what we are using now!
