Heat Storage

When sunshine is intermittent through clouds it’s still possible to use solar heat by forming a buffer. Heat storage in molten salts have been studied since the early 1900s. Molten salts have a great heat capacity, act like a fluid and can get very hot. Most of the studies in the past have been concentrated on energy generation with concentrated solar power-plants and nuclear reactors. The pumping and heat exchangers made it very complicated and expensive. For pyrolysis we only need a well insulated pool where the pyrolysis chamber in can be submerged. For the pyrolysis process we need a temperature between the 400 °C and 650 °C. Higher temperatures can speed up the process, it take a while before the whole pyrolysis chamber is heated up. Higher then 800 °C makes it difficult to work with, stresses, wear etcetera become to great.

About Egidius Kuhlmann

Reading about peak-oil, overpopulation, “Terra Preta” and biochar in 2009 and after making batches biochar for soil improvement from garden residue, I thought, why not make biochar from corpses. Deeply worried about the unsustainable path 'we' as humanity have taken, I see a future where fossil fuels are scarce, the western economic growth model in tatters, the global temperature rises due to the CO2 concentration in the atmosphere with an growing population reaching billions more humans than is sustainable? Thinking along those paths, the question “how can we dispose so efficiently and with the least amount of energy of human remains” became the starting point.
