According to the law of energy conservation, it is impossible to develop the last. It is only possible to transfer it from one look to another. There is a significant amount of ways of implementation of such transformation.
Instruction
1. To transform the chemical energy kept in combustible substance to thermal, burn it. The part of energy will be emitted at the same time in the form of light.
2. It is possible to turn thermal energy into mechanical in two ways. To use the first of them, burn substance in limited volume. Pressure which at the same time will arise use increase for movement of an object. The internal combustion engine works at this principle. For transformation of thermal energy in mechanical in the second way place liquid substance in limited volume and heat it in any way (not obligatory by burning something) to boiling temperature. Direct the turned-out steam to the steam-engine or the turbine.
3. For transformation of mechanical energy in electric construct the mechanism in which the mobile coil moves by a motionless magnet, or on the contrary. There is a set of designs of such mechanisms which are called generators.
4. To transform electric energy to mechanical, use the electric motor of any given design. Remember that, despite reversibility of the electromagnetic phenomena, as the engine not any generator, and only such in which when giving tension conditions for emergence of the rotating magnetic field are created can be used. For example, in the collector engine the continuous rotation is provided due to automatic switching of windings, and in asynchronous the rotating magnetic field arises thanks to food of windings of the stator three-phase alternating current.
5. For transformation of electric energy in light use various light sources: glow lamps, fluorescent lamps, light-emitting diodes, etc. Operate the last two types of light sources together with devices for restriction of current.
6. For development of thermal energy from electric use powerful resistors. It - perhaps, the only converter of energy with the efficiency close to 100%. In all other cases a part of energy when transforming is inevitably lost on allocation of heat.
