Maybe something like “Civilization” can be used too. It simulates an civilization from 4000 BC until 2100 AD. Fusion Energy is part of the achievable technology advances you can develop whilst playing.
There is an open source implementation called FreeCiv. Maybe it is possible to get them implementing a “grassroots fusion device”? A DPF? Requirements: Internet, Grassroots Collaboration, Search Engine, Plasma Physics.
BTW:
Question: What do you get, if you’re convincing people that energy will be eventually free?
Answer: They will waste more energy now, because tomorrow it will be free anyway. But how far is that tomorrow away? One year? Ten years? Fifty years? Thousand years? Million years? After the sun dies?
