    Heating water with a wind turbine

    Ask the supplier if a wiring diagram is available online to evaluate for your needs. I am not sure if you'll need excitation in the synchro generator from an electrical source? Here's a map of wind resource. I know a solar contractor who always puts up a tiny wind sensor on a tall pole to...

    Heating water with a wind turbine

    As I understand it, for heat production testing the plan is to run the electrical generator from a hydralic motor on a test bench to simulate output prior to building the actual rig. If you turn the squirrel cage with a drive torque it induces a magnetic field in the stator windings so the...

    Increasing entropy vs groundstate

    Here's an interesting link on the concept of a negative entropy source (the Sun): http://www.digital-recordings.com/publ/publife.html I recall a similar description in the book A Brief History of Time. My problem with entropy theory is that, if my brain recognizes a pattern, I call it...

    Heating water with a wind turbine

    abcrepair, Prairy Turbines sells a DIY system for direct grid-tie with a 3-phase motor. http://www.prairieturbines.com/theory.htm http://www.prairieturbines.com/purchase.htm Maybe there's some ideas here you could use.

    Heating water with a wind turbine

    I'm a firm believer that, in the future, green energy will be clean and widely distributed the way nature does it with chemical reactions powered by high energy electrons. Some have called this philosophy "the electron economy." I think the mechanical transformer (driveline) would be difficult...

    Heating water with a wind turbine

    Doing work directly on the water may be more efficient if the mechanical transmission is more efficient than the electrical transmission. The classic demonstration of the equivalence of work and heat is Joule's experiment of doing shaft work on a fluid inside a thermally insulated container...

    Heating water with a wind turbine

    In the moving air, a watt is proportional to the air density times velocity cubed. It hits the wind turbine and generates watts as torque times angular velocity, with some loss. It jumps the air gap in the alternator and converts watts to volts times amperes. So if you work backwards the volts...

    Heating water with a wind turbine

    Go to google and type "btu per watt hour". Result: 1 watt hour = 3.41214163 btu. This is just a unit conversion factor. It always holds. Your problem would be maximum rating of the heater element (high wind, high voltage, high current) and some estimate of the average watt hours (time...

    Heating water with a wind turbine

    From what I see here, the wind velocity probably has a v-squared impact on RPM, and the voltage is a linear function of RPM. The power output is a velocity cubed relationship. http://www.windstuffnow.com/main/wind.htm To rate the heater element begin with drawing a three phase source/load...

    Heating water with a wind turbine

    Not to discourage or encourage anyone, I offer a couple links to inform of current trends in energy efficiency. Generally the biggest gain in efficiency comes from using the heat load to also generate some electricity from the fuel (CHP, combined heat and power). In Europe and American cities...

    Heating water with a wind turbine

    I've been doing some multidomain simulations in the free version of DYNAST shell. The software has a learning curve, but provides a 3-phase source model that could probably be programmed to respond to wind speed. The loads are most likely simple resistors in a star or delta configuration, but...

    Heating water with a wind turbine

    The project is interesting and may have merit. As to why others have not thought of this? I offer some comments which you may or may not know. Generally a building, on grid or off, has an electrical load and a heat load. Efficiency improves by matching the load with a source. In a...
