I need to know what is the best energy out of wind, solar, hydro, nucular, coal, geothermal ("heat"), waves or tides before tomorrow so plz tell me and don't say none of them are more good than the others cuz I need one and one only

I am a farmer who is looking to retire. I would like to invest in an operation to feed the energy grid. A turnkey operation with available parts and sales reps? Or did I just invent a new industry? I want to retire to the desert southwest, USA.

I have to build a wind energy conversion device for my design subject. However, I can't use toothed gears, gearboxes, energy storage systems (e.g. flywheels, batteries, pressurised fluids, etc), rolling
element bearings and existing (pre-made) fan impellers.

So I need rough ideas on what are the things that can replace those items which can make the device moving.

A) length of time the wind blew and the wind speed
B) wind speed, water temperature and the density
C) wind speed, length of time the wind blew and the fetch.
D) the wind speed and the depth of the water

I am trying to find solutions on what people can do not use wind turbines because it has so many disadvantage of having it. I need solutions what can people do so we wont use them anymore.

I was wondering if it wold be possible to rig up a mini wind turbine on the top of a camper van so that when you are driving it would create energy to store in a battery.

Or would the extra energy needed to drive the van due, to the drag from the, any energy made by the turbine?

If so can you get mini camping turbines?

Thanks,
Martin.
Thanks for all your replies, they are great!

The plan is to use the turbine to charge a separate battery, not the actual one used to start the car. The second battery will then be used for music, laptop and other small electrical appliances.

I saw a guy on the UK version of Dragons Den who had a mini turbine but I was thinking that someone else must have done it already!

If anyone knows of any websites that sell them then that would be a great help too!

I look forward to your replies, thank you all so much!

Or is there that uses solar, electrical and fuel energy

produre harmful substances,
renew themselves very slowly,
are nonrenewable,
or vary from day to day.

now what i mean is that from which kind we can get maximum output....i don't care about today's technology what i want is from which we can get more....i think it should be solar because every photon has tremendous amount of energy which i think can't be harvested today but in future it can be...but my friends say its wind energy that is more....please help me out ..

would any of you be interested in asking your congressperson to maintain funding of these energy sources. by writing them or calling them or e-mailing them. if yes, why, if no why?

I have partnered up with a energy service that markets earth-friendly energy through a network marketing business model. I want to post flyers about it without violating any laws. what are some good places to post flyers about this specific category?

can not be already used!

i.e. the cost, efficiency and advantages of usin wind power instead of burning fossil fuels

i want to do masters in wind energy plz suggest me that wind energy has jobs in europian countries r in in any where ..

Please specify me the circuits.motor/dynamo etc.I need to achieve this please.
@booboo:but i need to make a portable one a hand held one.it needs to used while traveling in a bus or a train
Hello can any any one give me the idea???

I heard that the output was low, variable and the back up generators were on all the time - hence no reduction in C emissions and an unreliable wind energy input. Was this correct information?

I'm studying an article on wind turbines. The article says that for electricity generation, a wind turbine rotating at high speed providing a low torque is preferable to a turbine rotating at a low speed and producing a high torque. Can anyone explain why this is the case? Surely the speed could be altered easily using a sequence of gears before the generator?

and how does it get sent to people to use?
