Simple turbine turns dynamo powering a DC electric
heating element in insulated pipe, connected at entrance
to the solar heating storage in warm countries, or to the
hot water storage tank, in cold countries.
No need to connect to the current electric element, no on
grid considerations, no
need for special permits from
electric co. Safe, quiet, gives you hot water on cold days,
at an extremely low cost of production, installation and
maintenance.
Prior art: Wind driven heating piston, Wind heat, and the
baked Israeli product: Wind water heater. (All to be given
links soon)
Wind heater
MaxwellBuchanan's "better than electricity" idea - uses physics. Not this idea in any way. [pashute, Jul 09 2013]
Wind Driven Heating Piston
Bcrosby's mechanical energy idea I too have been thinking of since age 17, but it's not this idea... [pashute, Jul 09 2013]

(Hebrew) Wind heating water storage tank (Hebrew play on words with the name David Earning) Extremely expensive connects to a specific solar water storage tank. My idea does not use the existing electric heating unit, therefore it is faster to install, cheaper and simpler. [pashute, Jul 09 2013]

Water for cattle that freezes in winter could benefit from having a cow head size hole melted in the covering ice of the watering trough. |

although electricity>heat is pretty reliable and
efficient, wind>electricity is less so. So why not go
mechanical? Get the wind turbine to turn some form
of water-churny device? A propeller/centrifugal pump
or whatnot. The advantage being that the resistance
would scale with speed to some extent, so your
windmill would be naturally braked. You don't need
any swanky wiring/electronics/rare Earth metals etc. |

With either wind powered mechanical water heating or electrical water heating, it seems you ought to be driving a heat pump, not using resistive or friction heating. Sure heat pumps aren't cheap, but if you're going to go to the bother to construct a wind turbine, you might as well harness it well. Though the same argument could be made for simply using a quality inverter. |

Now if you're using rainbow wind wheels I can see how there might be an advantage to this solution. Pure mechanical heating would be much harder to hook up to a large number of small turbines, and the circuitry to convert the output of all those small turbines running different speeds could be expensive and not very efficient anyway, so using an individual resistive heater for each turbine might make a lot of sense. |

Water is nature's heat sink. There are more effecient
conductors, but none so enveloping. Developing heat is not
the issue; it's developing heat quickly and consistently. And
with that assertion, I cede the floor to the math guys. |

Seriously, its not doing it better, its doing it simpler,
cheaper, and with available parts. Images coming up
hopefully next week. |

Electrical energy is a bit like money; it is fungible (especially in the presence of a grid), there are various ways of getting hold of it, and the non-criminal ways are always costly. So "generate electricity by method X and use it for purpose Y" ideas tend to be a little tedious. |
|
| |
However, there just might be a case for dumping *surplus* electrical energy in a not-quite-useless way such as this, in cases where storing electricity is more costly than generating it (which I suspect is often the case), and there is no grid connection. |
