Geothermal COP is at least 4!

[gravityblock]

My cousin uses geothermal for their home with 12" of foam insulation in the walls.  At Christmas during winter, our family gathers at their house.  They will have all the windows in the house wide open cause of the heat generated from all the people and the cooking........and it remains hot in the house even 4 - 6 hours after the cooking with the windows still open.  They have 5 bedrooms with 5 bathrooms and a full size basement with 2 double car garage attached.  It is not a small house, so what would happen if you did this with a smaller size house?  You probably wouldn't be able to live in it, LOL.

There's a total of 7 people who live there.  They're always sick due to the house being over-insulated.  They even have air purifiers and filters through out the house to help.

Over-insulating your home will make it a germ factory and you will be sick a lot, trust me.

Thanks for the reply Jerry.  Yeah i did some reading and can see that it is not feasable to use a goethermal system for generating electricity.
evogreen.ca

the ones for commercial power are used to generate electricity by drilling two holes, they pour water down one side, which hits the heat and vaporizes, and a fairly strong force of steam comes shooting out of the other pipe, which they use on a crank


for residential, i would go for something similar to a stirling engine, or any motor that works on variations in heat, which would work best in cold places, which can easily be used to generate electricity
