Whats more efficient in terms of power generation and maintenance, a wind turbine or a windbelt?

boisk2 asked:
I live in MT. I am looking for grants that would help pay for some or all of the cost to build and hook a wind turbine to power my house. The costs for wind turbine are expensive but I would like to try to find alternative energy sources for my home.

How to estimate the energy of wind turbine?
how do i estimate the annual energy output of a 5kw wind turbine in an area which has a average wind speed of 7.4m/s at 10m above ground level, and the rated wind speed of the turbine is 10m/s. there is no buildins around to interfear with the wind and the hub of turbine is 12m above ground level. and could you show me the formula for this sum.

iLuvJoBros asked:
I’m doing a science project with my best friend, and we want to see if we can convert wave energy into the kind of energy we can use, like a wind turbine. So, we want to know how a wind turbine can convert the wind into energy, then we can do the same with the wave energy. PLEASE help.

BishopSherry asked:
Assume a wind turbine with a hub 50.0 m above the ground, a rotor diameter of 50.0 m, and a wind-power conversion efficiency of 25%. The turbine operates in an area with an average wind-power density of 500 watts/m2 at 50 m altitude. How much electrical energy (in kWh) can the wind turbine generate in a year?

I was just wondering how many kwh or mwh a wind turbine can produce on a average day. Can anybody help me out?

The megawatt size wind turbine seems to be a standard so why not have the cost of these machines available to compare with other type of electric generators?

sally_dood asked: Is there an inexpensive wind turbine. The only one I am seeing is this air-x thing which only produces 400 watts at 28 mph winds. AND ITS 500$!!!! Is there a turbine that is around the 500$ range that produces enough power to power the whole house???? Or is there another alternative????
solar is probably out of the question as it is so expensive.
