Heat is the worst form of energy. It's super hard to extract energy at all from it. Basically, you can't extract energy from heat itself, you can only extract it through the process of heating something up. So you always need a cold component that gets heated up and a hot component that does the heating.

Without a cold component, you can't extract energy from heat.
