To heat a medium sized room, assuming it is averagely insulated will take in the region of 2 to 4 kilowatts of power assuming the outside temp is perhaps approaching 5 to 0 deg C.

i doubt your wind turbine will provide this.

IF you insulated the room to a high degree to prevent heat escaping then your body heat will keep it warm

Suggest you invest in a good blanket and sew it into a bag with arms so you can wear it when sitting down.

I'm in agreement with Karnuvap and  like the idea of 'b", but you'll need to ensure appropriate safety measures so you don't inadvertently create a fire hazard. Not trying to be a busy body, but it has to be said.

Regardless of it's ability to heat a gymnasium, any heat you add is a good thing. Obviously, a single car heater isn't going to make your home a hothouse, but every little bit helps.

Make sure to provide power regulation to the heater circuit as well. A high wind situation could otherwise cause your heater to fail or again become a fire hazard.

Thanks I will use 24x 12v, 1.5amp voltage regulators, bridge rectified and filtered and fused , sitting in a metal chair plus self cooling with a metal fan,  connected to a book size aluminum heat sink that I took out of a 5oow amp the other day...

sounds good.

Don't forget some overcurrent protection inline, ie, fusing for the supply lines to protect from any inadvertent short-circuit situations that *may arise...

How many watts of power can your wind generator provide?

12V heating elements - that's what they're designed for.

I vote "b"

But Rick is right. You are unlikely to get that number of watts from a wind turbine and you'd be amazed how much heat a body can generate if it is well insulated.

Good luck sorting out your Anaemia.
