@RHarrabin @GSmeeton @Policy_Connect Roger, did you really imply today on @BBCNews bbc.co.uk/sounds/play/m0… that heat pumps "were not very well developed"? The sadly departed Prof. David Mackay wrote in 2009 "heat pumps are already widely used in continental Europe, but strangely rare in Britain.” … I wonder why? 1/
@RHarrabin @GSmeeton @Policy_Connect @BBCNews He continued to explain that if you took the gas used in a home boiler, sent it to a gas fired power station then used the electricity to run a heat pump, the heat pump would be more efficient and hence lower in carbon foot print, p. 151:- 2/ 
@RHarrabin @GSmeeton @Policy_Connect @BBCNews It is frankly infuriating that not only you but also @theCCCuk are talking up hydrogen as a fuel when air-sourced heat pumps (note: not just ground sourced btw) are a proven, available technology. I wrote about it here essaysconcerning.com/2019/09/07/ren… 3/3
@RHarrabin @GSmeeton @Policy_Connect @BBCNews @theCCCuk withouthotair.com should be mandatory reading for anyone offering solutions to decarbonising our energy. He said he didn't want to push any overall strategy; but he did want people to respect maths (and physics). Is that so hard @BBCNews ?
