Perfect Insulation At least another 41% cut in CO2 emissions can be realised if we convert all houses and industries to near zero-carbon emissions. This does not have to be expensive. The cheapest and simplest method would be to paint the surfaces of all rooms with Starlite, invented by Maurice Ward; this would prevent heat escaping and so minimise heating requirements. As far as I am aware, the secret formula for Starlite was passed onto his immediate family members so has not been lost by his tragic death. Starlite can also prevent heat loss with attempts to store energy with molten salt, and Economy 7 radiators. If we can store all the excess capacity of electrical generation at night then we can cut the number of power stations needed so storage of energy is important. Maurice Ward Information See: https://www.starlitethermashield.com/ (This figure assumes that 80% of heating is by gas, and that domestic gas use is 29%, and industry heating is 22% of total energy consumption.)   An alternative to Starlite is Firepaste, invented by Canadian Troy Hurtubise, we were looking for financial backing for lab time so that he could make a household paint out of it when he died, a great tragedy not only for friends and family, but for the environment as well. RIP. As both Maurice and Troy said that they made their inventions out of household products I am attempting to get a government lab set up to recreate their inventions.  If you look at this YouTube video https://www.youtube.com/watch?v=aqR4_UoBIzY you will find the the likely components are 90% corn starch and 10% baking soda mixed into a putty using PVA glue. There may have been other components as well, because it has been made into a spray paint, and paint. You will need to crack the formula in order to make use of passive temperature control of buildings. You might even be able to improve upon them both.
