Meh. Tech wazzocks inventing yet more stupid gimmicky solutions when we already know exactly what to do and could do it now.
If we just insulated to passive house standards an average 100m2 British house would need about 1500kwh a year to heat it. With a modern air-water heat pump that’ll be less than 500kwh of electric burned. <£200 a year at today’s mega high prices.
Hefty

You and Yours on BBC R4 yesterday was interesting (there's a phrase you won't here very often):

It was about future house-building tech and how the Future Homes Standard (the new energy efficiency requirements which come in from 2025) will be met. Lots of interesting new heating ideas like infrared mirrors in bathrooms and heated metal skirting boards. Also a lot of emphasis on heating in a smarter way (such as aiming the heat at people not big spaces as I mentioned above).
