I have been having some success heating my house with a device that consists of unpressurized proteins, sugars, starches, and waters that undergo heating via an electric resistance.
Here are the salient facts: Flour Eggs Water Sucrose Vaniila I mix these together in a reactor vessel constructed of stainless steel and place them in an insulated cabinate where they are heated several times for a period of time, and they undergo a transmutation. When the heater is turned off after ramp up the reactants change colors and their physical properties become different. I can then remove the reactor vessel out of the ramp up box and place it carefully on an insulated holder, but have to take great pains not to touch as temperatures are dangerously high. It smells quite delicious and remains quite warm for quite a period of time. After which even the heating box is now hot enough to comfortably warm the entire lab area. I'm considering the manufacture of these as the by product alone may feed an army. Any thoughts??
