Free electricity, will bt be profitable again?

[4g0tt3n]

Im currently running a 50 5830 rig site, recently just pulled the plug
for them
Switching into Fpga will put all my 50 card to a waste
solar panel is way too expensive to set up

Starting a project on setting up a solar stirling plant which
generates free electricity
tested on a small rig which cost $80 to DIY and it has enough energy
to run 9 of my card in 3 rigs

currently setting up a 4ft by 4ft site... 500MW solar power plant
cost is around $500

I'll update you guys here if I have any luck with it
