The design and production company "Motochrom" proposed the concept of a portable mini-thermal power plant for hiking and trekking expeditions. The idea for the device emerged back in 2018, the company reported.
According to the developers' concept, the device should consist of three main units. A stainless steel capsule with a volume of about one liter is intended for water. A 1.5-meter long, 3/4-inch diameter stainless steel bellows is screwed to it. An electric generator unit with a turbine, rectifier, and valve system is attached to the other end of the bellows.
The user pours water into the capsule, screws it to the bellows, builds a fire, and places the capsule in the fire. The water heats up and turns into steam. The main valve must remain closed until the pressure in the capsule reaches 30 atmospheres. When the pressure increases, the valve opens and supplies steam to the turbine, which rotates the generator rotor and generates electricity. When the pressure drops, the valve closes. A safety valve will release pressure if it exceeds 120 atmospheres.
The main advantage of such a system over solar panels is its independence from the weather. The concept suggests that the device will be able to produce up to 600 watts of power. The question of production remains open.
