By Jeremy Williams The transition to entirely clean and renewable electricity is well underway in Britain. Radiators might need to be upgraded. It can be disruptive, and then there are new habits to adopt around the different technology. Homes are all different, and there’s no one-size-fits-all technology for renewable heat.

The first thermophotovoltaic cells with an efficiency of more than 40% – higher than any existing solid-state heat engine, and exceeding even the average efficiency of turbine-based power generation – have been fabricated by researchers at the Massachusetts Institute of Technology (MIT) and the US National Renewable Energy Laboratory (NREL).

Devices known as optical rectennas show considerable promise for renewable energy because they can harvest energy from heat and convert it into electricity. Rectennas (short for rectifying antennas) consist of two parts: an antenna, which absorbs electromagnetic radiation, and a diode, which converts the absorbed energy into direct current.
