Question: when you make crystals and turn it into electricity , how long does it lasts???

It lasts as long as one side of the crystal stays hot and the other cold.
Maybe you have heard of the voyager space probes. They are the furtherst man made objects from earth- this is how they work. They were sent up with devices like the ones I make and a red hot nuclear soucre. The little devices harvest all the heat from the nuclear waste and turn it into electricity. That has been going on since the 70’s! and it will keep going until the nuclear part is as cold as space
