Solar engines and thermodynamic systems with volatile gases. Nova Somor srl was founded with the intention of designing, creating, building and marketing products capable of fighting the unacceptable energy waste that has been going on for many decades. Thanks to a careful and innovative application of low-temperature thermodynamics, in many areas it is possible to replace electricity with sunlight, which is plentiful and free. In other situations, wasted and thus squandered heat may be used to increase the efficiency and ecology of existing systems, without forcing demanding changes. The area is that of bio-economy; that is an economy that for its actions takes into account any impact it generates on the ecosystem, the biosphere and people, and that especially focuses on the impact it has on future generations. The Somor of the 50s, of which we have picked up the history, carried its vision in its name: “Engines for recovering wasted and solar heat Company “.This is our inspiration as is fully described in our Manifesto. To Somor’s old slogan “cost effectiveness, practicality, utility and simplicity” we add “ecology and ethics”.
