It's been a long time since I have heard a peep about OTEC – Ocean Thermal Energy Conversion. How it works is simple, it uses the temperature difference between warm shallow water and the low temperatures in deep water. The limitation of this approach is that we go through a turbine run by steam so […]

I love the high tech in Solar but I really appreciate the simplicity of Wind turbines and Wave turbines. Here is a nice pilot project I came across being trialled just off the Scottish coast. North sea oil probably cost the Wave and Tidal power industries a couple of decades in delays. Now that we […]

Wind power got an early start on solar energy. The technology was simpler and the engineering was easy. So the turbines sprouted in hill fields and farms and then it got close to homes. That’s where the trouble started and where this film comes in…
