These technologies are existing since 115 years (heat pump) and have been mass produced in the 1950. The article is unwillingly misleading. It is not new technology per se, it is an improvement on a very old technology that is as simple as the Sterling engine. Britain (France) has been a massive adopter of this, having a paradoxal effect on aggravating the power peak in the morning inducing the use of coal plants to be massively used in the morning to face this peak since pump were electricity driven. But with mechanical wind mill, or solar power maybe they could finally become green. As usual evil lies in the details, and most new new techs are deceptive because we lack knowledge. This is an old tech, and we know the trap.
