]]> Comment on Can you use a car alternator to build a wind generator? by Tiago Silva http://www.earth4energytalk.com/wind-generator/can-you-use-a-car-alternator-to-build-a-wind-generator#comment-3558 Tiago Silva Tue, 25 Jan 2011 16:49:32 +0000 http://www.earth4energytalk.com/wind-generator/can-you-use-a-car-alternator-to-build-a-wind-generator#comment-3558 P.S. - If you want a system that can convert the energy correctly you should not use a voltage regulator, that just cuts the voltage when the wind is faster... Take the regulator off, add a full wave bridge rectifier and connect it to a DC-DC converter with a variable input and a fixed output (Ex. http://pt.farnell.com/sunpower/sds-060b12/converter-dc-dc-60w-12v/dp/1254997) but if you search a little you will find more DC-DC converters. Note: Using a DC-DC converter is the best way to harness all the generator energy, independently of the voltage it is generating! But for costs sake, you can use a simple voltage regulator (or many in parallel).

High voltage can be achieved with higher speed, but to achieve more current you must add stronger magnets and upgrade the wire to a more current capable wire, which will turn out to be thicker too. This will require some trial and error, but you will be able to make it work better than a commercial generator. To get some neodymium magnets in Europe check this site: http://www.supermagnete.de Also, there are some tutorials on the internet. Cheers. Well, to make the best out of a car alternator you should:

Otherwise you will be replacing them regularly. 2) Run the spin cycle on your washer twice. The more water you spin out of your clothes the less that will drip or need to evaporate. 3) Start your first load of wash before you sit down to supper. This way when you are done cleaning the kitchen you can set up a rack of clothes in there to dry through the night. Then the second load can be placed in the living room right before you go to bed. 4) If your clothes do not get dry overnight try leaving a ceiling fan or floor fan on for added air circulation. This does use a little bit of electricity but not near as much as a dryer.

But I am afraid that the way government's work is that they would not like to see this level of independence from mere citizens.

Also, there are many carcinogens and solvents in this type of oil. It would have to be significantly refined (at great expense) in order to be useful as a fuel.
