.on how to keep the house better insulated without actually tearing down the walls and stuffing insulation in themWe were going through one full tank of gas every two weeks this past winter and we can't do it again this yearI know that it is not the tank itself that is losing gas because one tank lasts us the whole summerThanks.
the curvature could be difficult you could look at a model shop they would have air plane propellers these would have a similar shape to what you need.making one yourself would be almost impossible as the shape changes along the whole length its almost flat at the tip if you havent started the project i would suggest using a very small motor engine one like a model race car has they have very very small torque and they also generate about 5 to 12 volts of dc which would be enough to see it works .
I would suggest using the spray foam in the attic and sealing all the cracks that you can findRemember, heat rises so you will lose most of the heat that wayThere is also is a liquid that you can inject into wallsIt takes time but what you do is drill a small hole in the corner of a wall (make sure that you are able to plaster the hole when finished) and you actually inject the wall with an expandable liquidIt turns into a putty/foam which fills all the cracks and travels upwards so that it will not push out the wallYou should definitely weather proof your windows by using a plastic wrap that keeps the cold air out or replace old windows if financially ableHeat can escape out of electrical outlets that are on outside walls as well so I would suggest using the plastic inserts to keep the ones that you do not use sealed in the winter.
Buy a fan from kmartPut it in a windy placeThe motor will function as a generatorMeasure the voltage and current produced at the plug with the fan turning with the windGet a light or some other load that will energize with the power you produceWrite a nice report on generators motors and reverse power.
