A New Way To Save Heat,

at the moment comes in the size of a small coin, but researchers at The University of Nottingham's Chinese campus believe that the properties of this material mean that it could be sprayed onto any surface like paint, it will allow walls to absorb heat during the day before slowly releasing it when the temperature drops, making your wall a radiator, the product, named non-deformed energy storage phase change material, or PCM, works by storing excess heat from a room, the material can be set to store the heat when a room's temperature passes a certain level, for example the optimum room temperature of 22c, above a certain temperature the particles within the spray melt, but instead of dripping, they are held in place by a special coating, the material then becomes a solid, releasing the heat into the room where it is being used,

the team, led by Professor Jo Darkwa and his colleague Oliver Su, have said that the material will work as a spray, forming a microscopic film on surfaces, also of interest as the British Government has slapped more 'green' taxes on aircraft tickets this year is the claim by Professor Darkwa who said, 'the construction industry produces more carbon emissions than any other industry in the world - even more than aviation', last time I looked air tax on tickets cost the UK's flying public £2.2 billion, of which little if any was spent on 'green' agendas, I wonder how much the building industry put into the government coffers?
