Energy underneath your house?
I've being thinking on how to get off grid for a while now, in the first stage to use solar power to get the energy bills go down and in second place to get my stamp on earths energy consumption, using my house in a greener way.
So solar energy and wind energy are on my mind, but recently i started to think about more possibilities.
Like using my crawlspace to work for me.
Maybe its posible to make a wind turbine underneath the house, or use the constant temperature to cool my house during summer.
I've seen plans on the internet ( and cant find them anymore... ) about using a sort off vacuum chamber that has a constand wind flow comming in, trough a system of pipes that drive a wind turbine inside.
The idea is that, because of the vacuum effect, you need only a small gust of wind to power the turbine.
Where i live theres always wind, sometime a little, sometimes waaay to much.
The crawlspace i have isnt that high, about 50CM in hight, and during the Fall and Winter months theres a high level of water, about 25CM.
Durring summer its mostly muddy sand, so there's stil a lot off cool water trapt in there.
So about the idea on cooling my house, how about a water cooling system that runs trough the house?
How would you guys make such systems, have you already tryed this out, and are there some enthousiastic folks out there willing to go all the way and show these idea's are doable, so everyone can make it???
Hope to hear from you soon ;-)
