In this category, I will list some of the technologies that convert energy from one (unusable) form to a usable form in human environments.
Target technologies include:
Solar Stirling Engine
A solar stirling engine is a machine that concentrates the sun’s radiation through a parabolic reflector to a point of a stirling engine. As this point heats up, there is a heat differential, and air (or other gas) is compressed so that there is a net conversion of heat energy to mechanical work.
Microbial Fuel Cells
A microbial fuel cell is a system that uses bacteria or other microorganisms to drive an electrical current.
A wind turbine is a machine that rotates as wind flows through it, converting the wind energy first into mechanical work, which drives a generator and produces electricity.
Dinamo powered Generators
A dinamo powered generator is a machine that uses human mechanical work (or can be attached to other moving objects) and converts it into electricity.
Gravity fed Rainwater Generator
A gravity-fed rainwater generator is a machine that will collect rainwater in an elevated reservoir (with potential energy), and when the water is used it will flow through gravity through a generator to produce electricity.
Aluminium Can Solar Heaters
An aluminium can solar heater is a machine which re-uses aluminium cans by cutting and placing them into long tubes, painted black, so that they can absorb the sun’s radiation and transfer the heat into a fluid (air or water) going through the tubes.
A windbelt is a machine which uses the principle of aeroelastic flutter to trasnfer wind energy into a vibrating belt that is attached to a generator to produce electricity.
