what I was trying to do is test this theory with something I had around here. but I have come to the conclusion that I must use a synchronous generator because what I want to prove is that at low generator speeds (low voltage) I can get the 3.41Btu to Watt thru a element that can take the max...

I am making progress on testing this plan. I could use "engine block heaters" for the elements. I can get 200W to 1500w 120V or use the standard hot water heater elements. so the next thing is the generator this is maybe were you guys can help. I am trying to find something I might have that...

I am sitting here thinking how could this be. someone needs to come on here and say this won't work. so what you are saying is, If we put a given amount of voltage in a heater element made for 120V we would get the same amount of btu's if we put it thru a 240V element ?

That was a good link for building a wind turbine. I agree the test stand will only give voltage to RPM, the wind turbine will determin the amount of power at a given wind speed. I have all the flow charts and power curves for the turbine at different wind speeds. I know I can make power with...

You guys have got me really thinking ! I could throw together a hydraulic test stand together real easy. I would just need some type of generator that matches the wind turbine. then I could simulate wind speed with different hydraulic flows and try different elements. I am still not sure on the...

Russ, when I built my shop I ran 1200 ft of 1/2" "pecks" tubing in the concrete floor, 4 runs at 300 Ft each. the part that has heat in it is 32' x 40' and 6" thick. the concrete will crack if you get the water too hot. I run the boiler at 110 deg. the good thing is that once it is warm it stays...

Russ, I would agree with you if I was looking to make "domestic" hot water. my goal is to store the heat in the concrete floor. or hook it to any hot water heating system. it would be simple to turn on the curclutator pump when the water tank got up to 120 deg. my thinking is use this as a...

I have looked into some different types of water heaters. the instant water heaters or hot water on demand are huge energy users infact most times a normal household doesn't have enough power to run one. IE 200 amp service. I have also looked at a 3 phase hot water heater but they are all too...

It is funny you said that, I have been thinking the same way all morning. the wind turbine is a Synchronous permanent magnetic generator 3-phase 16 poles. I have all kinds of alternators from tractors and a 6000 watt gasoline powered generator to play with but I don't think I could make the same...

Well, I didn't think this was going to be so easy, or someone would have done it by now. I was a service manager in a standby generator company for a few years, but that was completely different. the voltage was always constant (with regulation) and the KW was relative to engine HP. with "wind...

That is a very good point ! I will have to take one out and look at it - see how it works. I just happen to have one in the shop now for a engine rebuild. the switch works thru the ground side and it is not very reliable, so a lot of guys just unhook the wire and check the coolant level by eye.

Hello, I repair farm machinery for living. most tractors have a switch in the top of the radiator for the coolant level. it is a 1/4 pipe thread with one wire connection when the coolant is in contact with the switch it is open, when the coolant level gets below the switch it closes. in a...

Wow! Everyone has been so helpful thanks. so here is what i am thinking: the turbine I will be using puts out 270V three phase at rated wind speed (28 MPH). I would need the turbine and a wind control unit to regulate the turbine speed or "over speed". then take 3 standard "off the shelf" 120V...

I agree that solar collector systems are cheaper. what i am working on is becomming a wind turbine installer. the "off grid' and "grid tie systems" are costly with all the controlers and batteries. but they are proven to work. I am just looking for a different angle, If I could set up a system...
