Make my own turbine or....?

I'm going to be building a charging station for my laptop, cellphone, ipods. I got the idea from the S.P.R.E.E. article but I want to incorporate a wind turbine into the system. I'm struggling to find a turbine that's small enough, or even a permanent magnet DC motor. Am I missing something or would I have to make my own DC generator? Thanks in advance!

Wind turbine to charge batteries

I have a solar electric system with a battery back up for power outages.(it is also grid tie) I would like to add a wind turbine to charge the batteries in extended outages with no sun and hopefully wind ( we normally have low wind but storm outages have lots of wind). The batteries are 12 volt connected in series to produce 48 volt. Can I, should I, get a 48 volt turbine and connect direct to the batteries or some other voltage and go through the inverter like the solar panels do and if so how and what voltage turbine?.. Chris

Tesla Turbine Bike

I was curious if anyone has created an air compressed tesla turbine bike. Using a 4500 , maybe even 2 4500 carbon fiber tanks. Something along the lines of this instructable Just curious if anyone has tried this, sort of thing and if it was plausible, and how long the tanks would last or if there was some other design such as directly hooking up to the gears.

Can you use an intermittent bursts of air to control the output RPM of a Tesla Turbine?

I've seen plenty of these projects using a constant stream of air to turn the turbine. Surely with the combination of rotational inertia and an intermittent jet of air a constant rotational force could be sustained whilst conserving the compressed air available?

Building a Wind Turbine for the first time

     I'm building a wind turbine for the first time and I want to share my progress and chat with people that have done the same type  of thing.       I'm a member of many different forums online and I value the information I pick up from them a great deal.  (OK here comes the question) I've been looking for an online community of people that share this interest (residential wind power) but I'm not finding any large groups,  or a central hub of knowledge. My question is ,  Does any one know of a large high traffic wind turbine forum ? My Googlefu seems to be weak in this area :(

3 phase bldc motors as a turbine. i am quite confused on how to determine which leads to us or how to configure them.

Ive got some electrical backround but dc seems to be where i get lost.  these motors i have were used in some sort of factory.  the motor has three leads and a ground. any help would be greatly appreciated

Wind turbine questions.

I am asking these questions on behalf of another member who has English as a second language. He is building a vertical axis wind turbine (savonius style, I think).  The mechanicals don't worry him, it's the generator and the windings. He wants to arrange six coils and six magnets.  The magnets are going to rotate with the turbine.  He has made the coils himself - each is wound clockwise, with 100 turns of wire. He assumes (and I agree) that the magnets should be separated by 60° of the circle, alternating which pole faces the coils (S-N-S-N-S-N) and the coils should also be separated by 60°. He would like to produce 12V DC, to be fed into a battery. What is the best, or most appropriate way to connect everything to achieve his goal? Links to sites that he can examine (and/or translate) at leisure would be nice.  Or sites in Turkish. (I suspect that Picoturbine documentation would help, but it's in long English.  Still, I've added it to the topic in case it is of help.)

Wind Turbine from a cordless drill?

Hi guys i have come across an old 18volt drill. i connected it to some small pvc blades about 12 inches long in the hope of generating some small amount of power. Pointed it into a reasonably stiff breeze but the blades wont turn due to the gears of the drill. Anyone out there got any ideas on how to make this work.  is there any way to free the gears so it turns easier or any advice on what size blades would be required to turn the motor. Any suggestions would be appreciated. sam301

variable output dc water pump for a wind generator

I'm interested in figuring out how to direct the energy produced by a wind turbine into a water pump. My goal is to pump water from a river to the top of a hill into a pond. then slowly release it through a variable water turbine so that the pond serves as a battery. i've seen pumps that work with the power take off(PTO) of a tractor that could be retrofitted if i had the right dc motor. i need to figure out what motor might work and what type of contolling i would need. also would it be better to use several smaller units that engage one at a time as the power input increases to keep the pumps closer to thier ideal operating range? The (PTO)water pump i saw operates between 17-23 hp or 20kw or less, which is perfect because the turbine is 20kw. the other thing is what if the pump operation starts at 17hp(?) then most of the power would need to be directed somewhere when producing less. maybe a series of different sized pumps and a controller to determine which pump(s) to engage to get the most water pumped.

Using a fan to drive another fan

Hi all, This may very well be a stupid question but after a quick bit of searching I cannot find an answer (which probably means it is stupid). I have been thinking about setting up a wind turbine to generate some electricity for my home. It occurred to my that it would be good if the wind turbine did not rely solely on the wind from outside so I started thinking about using another fan to blow air into the fan or fan used to create the electricity. Does anyone know if this is possible? I guess what would be ideal is if fan A was powered by the electricity produced by fan B but fan B also produced a little extra electricity that I could syphon off. This could then easily scale up to produce more power. [ fan A ] ~~~~~> [ fan B ] ~~~~~> electricity I suppose if fan A takes more energy to run than fan B can create then it won't work. Has anyone looked into this?

Since the whole unit turns 360 degrees, how do you keep the wires from getting tangled up ??

I did not see any set up where brushes are used to carry the current from the generator to the stationary unit (Batteries, inverter, etc)

I am trying to find out if wind turbine generators have a maximum rpm or if they just keep producing energy. if so, my next question would be, does generators maximum output have a maximum rpm. if it spins too fast because the wind is very strong that day, will it affect the turbine and cause it to overheat?
