Every first year engineering student knows that you can generate a tiny amount of electricity from a thermocouple with one side hot and the other cold. But this effect has been so utterly inefficient that it is a novelty, not a useful process.
But that seems to have changed. This process is 40% efficient. Even a standard turbine generator, state of the art is only 35%.
This is phenomenal! If this proves out, it will be a revolution in energy generation. It means that heat sources, which are very plentiful in today’s world can be made useful.
I’m not sure I can explain the potential without the massive nerd speak of which I am capable, but believe me it is there.
