Geoengineering is a set of emerging technologies designed to manipulate the environment and offset some of the impacts of climate change.

These technologies are typically split into two categories: carbon dioxide removal (CDR) and solar radiation management (SRM).

Thermodynamic Geoengineering (TG) is the third way.

It is the conversion of the heat of global warming to productive energy as was first demonstrated by the Greek, Hero of Alexandria, in the first century AD with his Aeolipile .
