How to make a program which generate electricity!?

Question

#-#=O

Answer 1

Yes, run the following
electrons = 2;
do {
electrons *= electrons;
} while(powerIsOn);

Answer 2

keep cpu and gpu running above70% use all available ram, and you will generate high electricity... bills.
Seriously, you can generate frequecies in software that can be emitted by an antenna. A grounded receiver antenna struck by the generated electromagnetic field would produce electricity through inductor coils.You can't expect to run your pc but with suitable circuitry, you can very slowly (and inefficiently) charge a phone that way.
you can also pulse the usb 5 volts through the coil of a transformer. The inducted electricity on the other coil will be the indirect output of your program
