The ISS is kind of heavy, it's the size of a football field and it has been a success, if they didn't have any problem with assembling the components I don't see why assembling the turbines would be more difficult, actually it would be easier. There have been 135 launches to the space station since the launch of the first module (by the way the 90 kilowatts of power for the ISS is supplied by solar panels). You can simply send on space sections of gigantic blades ready to assemble and spin at incredible speed generating lots of power, this is not Star Trek. For the space station they spent more or less $100 billion, which is nothing if you compare it with all the money we spend in oil and energy bills.

how you will spin at incredible speed to generating lots of power?????

as you study more you became more smarter .

as simple it is .

Absolutely agree - just giving one problem even if the sails were as large as ,say, an earth sized planet.

that is not feasible. the cost of that sails will be very very high.

instead of that using solar panel on earth will be cost effective.(which are not use due to its cost).

There seems to be an idea that solar sails might provide enough energy to rotate the windmill. A big problem, it seems to me, is that somehow the main body of the windmill needs to be firmly fixed to something. Firstly, you need to stop the solar wind from pushing the windmill along. Secondly, if the solar wind could cause the armature to rotate it would drag the body of the windmill around with it because taking energy from the windmill would cause magnetic coupling between the rotor and the main structure. If the whole thing rotates together then no energy will be generated.

wuz here and TonyMcC

if at all you installed so called space wind turbine it won't rotate because solar wind dose not have as much density as air,

The solar wind is a stream of charged particle it has very less density.

"At the orbit of the Earth, the solar wind has an average density of about 6 ions/cm3. This is not very dense at all!"(negligible)

the formula for wind turbine generation is

power=0.5*area*density*velocity³

hence your wind turbine will not get enough power to rotate.

moisture is presence of small amount of liquid in substance (especially water).

humidity is nothing but water vapor holding capacity of air. i.e when we say 60% humidity ,the air contain 60% vapor of its capacity and if there is 100% humidity the air can't take any more water vapor. hence when you will sweat in 100% humid air the sweat will not evaporate becaues air will not be able to take any more vapor .

you know when you are in AC room your body sweat's but sweat evaporation rate and sweating rate is same hence you fell cool and you don't understand that you are sweating.

relative humidity is the amount of water vapor in the air at a specific temperature compared to the maximum water vapor that the air is able to hold

myuncle,

your idea will not work because due to FRICTION between stator and rotor of generator it will stop.

there should be some energy input to generate energy, i.e you can convert energy from one form to another (energy neither be created and nor be destroy) .

you can't make perpetual machine.

hey i am tom redy. I am interested in energy related subject.
