Eric, If you want to have flexibility, you should have a low temperature heating system and floor heating is ideal. To this you can have a larger number of heating sources to choose from and better efficiency. It is also wise to use the buildings accumulation potential, instead of being depen

Hi, to my mind, a car alternator will rev about 2-4 times the engine revs. The size of the alternator pulley is about 50mm & the crank pulley is 100-125mm. This gives 2+. A car alternator will rev fairly high, because the rotor diameter is only small: about 80mm from guess. Usually the slower

Commercially produced microturbines typically run at 20,000rpm or higher (I think some are 100,000rpm). Check out Capstone's website http://www.microturbine.com/prodsol/techtour/index.asp Perhaps that alternator is made for that but probably not. On 12/8/06, Hakan Falk <[EMAIL PROTECTED]

Hi Hakan; If the diameter of the pulley is doubled the circumference is doubled. Not 4 times. You must be thinking of area. Now if you double the diameter on a wind turbine you do get 4 times the power. Is this what you were thinking of? If a 3 meter turbine produces 1kw ( a safe guess

Joe, Twice the diameter, would be close to 1 to 4, right (THE SQUARE OF 2)? Agree that 2,500 might be close to normal speed. That would be something like 10,000 rpm for the alternator at normal speed. Talking about that the alternator would explode at 18,000 rpm is maybe an overstatement? Wi

Hi Hakan; I bet the pulley on the crankshaft is less than twice the alternator's pulley diameter. Also the amount of time your engine is reving above 2500 rpm is short compared to the normal. Anyways they talk about low losses but the gearbox required to turn the alternator that fast would b

Joe, How much are they spinning in a car? To me it looks like the wheel on the alternator is much smaller than the wheel on the car engine, could it be 1 to 4 or more? 4,000 rpm for the car engine is quite usual, so the alternator can not be far from 18,000 in normal conditions. Just a though
