We have these already .. that's actually half the problem:http://forums.whirlpool.net.au/archive/1304164
You see we are charged more for the peak rate because we have solar and thus a smart meter than we would be charged without it. I also live with my parents and they
will freak out if I am using their electricity to mine bitcoins. They actually want to see themselves getting a credit for the power they supply back to the grid rather than a bill for what they
draw. My mum goes mental if I leave a light on so I am doing my best to change most of the lights in the house to LED and I want to sell off all the LCD screens in the house and replace them with LED screens. I have started paying money on their power bill via direct debit from my bank account every fortnight but it still won't make financial sense at the rates we are charged.
I am also looking for other alternatives e.g. I live in a horse racing area and there is a lot of horse shit that the horse trainers can't get rid of fast enough. I would like to make
a horse poo - > methane -> electricity generator.
so then I have horse poo -> methane -> electricity -> mining rig -> bitcoins
Something like the examples here:http://www.builditsolar.com/Projects/BioFuel/biofuels.htm
or this story here:http://beta2.tbo.com/news/suncoast-news/2010/mar/05/wp-plant-turns-horse-manure-into-methane-powering--ar-73553/
I have been looking for open designs and resources like this:http://bio-gas-plant.blogspot.com/2011/04/homemade-biogas-methane-gobar-gas.html
and I'm looking up videos about the subject like this:http://www.bukisa.com/videos/331437_how-bio-gas-digesters-can-sell-energy-backhttp://www.youtube.com/watch?v=XJSmI-aONio
I will also need to buy, build or modify a gas combustion turbine.
I would probably make a very low power machine and still bitcoin on it and get it to hash even if its a very slow hash rate simply as a proof of concept.
A more exciting possibility is perhaps even using bacteria to produce electricity directly:http://www.youtube.com/watch?v=8n1LsafQ194
