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.

I have a small remote cabin with good sun access and a fairly steady breeze that I visit about once a month. I want to install solar panels and a small wind turbine, but all the books I have read seem pretty complicated. I would like step by step instructions on how to install this system with recommendations on panels, charge controllers, inverters, and batteries. Also feel free to recommend low voltage appliances and lighting. Please feel free to dumb it down for me. I will be doing the instal myself as the cabin is only just now framed in with not interior walls. Thanks!

How small will a windturbine charge? Small turbine for small batteries?

And other alternative renewable energy sources?

I just do not understand. If you do not like it please tell me why, or if you do please give me your opinion why others do not?

Be nice & thanks
I actually like wind turbines, they are beautiful and look like giant pinwheels!
Seriously Andy? There is a thing called batteries..that is like saying 'I am afraid my cell phone won't work if its not plugged into the wall!'

And the environmentalists totally wants alternative energy.

I am making a small scale wind turbine for school as an independent study. I will be following the plans on the following sites/videos:

I will need a way of measuring the power generated and will probably require a battery bank to do this.
I'm sure it will depend on what motor (generator) I use. I was planning on using an old treadmill motor if I can find one and if not probably one of these:

My question is what form of battery should I use? I have a relatively tight budget and would need the biggest bang for my buck. Should I use a bunch of 12 volts? larger? when it comes to batteries I'm kind of clueless so any help is VERY MUCH appreciated.
It will be running for quite some time and I need to track how much energy I can generate over an extended period of time without using a logging tool (they cost too much)

just like they charge batteries by solar energy and make the car work on that battery....can they do the same with wind energy?

if not, why?

i mean scientifically or financially or commercially
but why can not we charge batteries by the wind energy, by wind generator i mean....just like we charge batteries by solar energy....and then we let the car work on the battery

Where is the new tech in solar, wind, electric, hydro, efficient batteries, etc? Why is everything developing so slowly?

The four choices are:

1. Graphene Based Ultracapacitors
2. Urea as a hydrogen carrier for fuel cells or Internal Combustion Engines
3. Rechargeable Metal Air batteries
4. Other - got your own idea

It would be nice if you could also explain why you think that energy storage method is more promising than the rest.

The use of the energy storage is mobile, such as vehicles.

If you there was a human sized robot in a space craft, what power supply would it run on? (Besides batteries/fossil fuels) As well, what power supply do nanobots run on?

It would seem logical that using energy from coasting downhill to recharge the batteries along with solar panels and some sort of wind recharging device could be manufactured for a really cool bike. Just a thought. Love to hear what you think!
As far as the solar element, they are now manufacturing "solar panel sheets" that are extremely light, almost like a saren wrap that would cut down on weight.

Can a small scale wind generator power enough batteries to power a 5 ton air conditioner? And if it can, how large of a battery bank would I need, and would a 220 power converter be good enough.

A company claims to have solved the problem of storing energy from renewable sources using giant gravel batteries:

What do you think?

just like they charge batteries by solar energy and make the car work on that battery....can they do the same with wind energy?

if not, why?

Alright, we cannot drill, we cannot have nuclear power.

I wish I could take a leak into my car and make it run, but the technology is not there right now.
How long before we can make semi-trucks and airplanes that can run on renewable energy?

I've seen these vehicles with 30 batteries on them, but they can hold no more than a suitcase (if they have a trunk at all) and the waste from the batteries is more toxic than gasoline emissions. By they way, they cannot run at freeway speeds.

I want to work on renewable energy specifically building science and renewable energy stores like sell solar VP.solar thermal,hydro,batteries,pumps,etc... but in building science I have to install those products so what should I study,which career fit better?

1. How do I set up alternative energy source using thermal energy?
2. What equipment do I need to support a 7000 sq feet of living space?
3. Where do I obtain the equipment and batteries?
4. Where do I obtain the technical know-how?

Stick your hand out the window, feel the strong wind flying by your car, why couldnt they install special vents on the front, side and back to funnel that wind into some type of turbine that would create enough party to continually charge batteries
