Engine with mechanical energy

Just as one can make steal a small airplane-toy by means of a propeller driven by a rubber band, one tried to create engines where a mechanical storage of energy was used instead of a thermal energy source, electric or hydraulic.

The field of the toys

It is simplest to implement simple of way these techniques, taking into account weak required energies.

Kinetic energy

Wheel-helicopter (“flying saucer”)
Car with friction

Compression of gases

self-propelled Ballon
Fusée with water (which reaches 10 to 30 m in height)
Moteur compressed-air

Elasticity of the solids

Airplane
mobile Vehicles with spring. In addition to the cheap mechanisms whose speed regulator was often a little noisy, one will be able to quote the very quiet cars Schuco . The famous play Meccano laid out him also of two engines with spring with its catalog, of which the Magic .

The field of transport

Kinetic energy

Vehicles at wheel of inertia

Compression of gases

Locomotive tires with the exposure of 1900

Advantages:

Silence relative of operation
Very few escapes at rest compared to an Electric fencer
Complete absence of Pollution

Disadvantage

Change of the bottles forcing

projects of pneumatic car

Advantages
Disadvantages

Vehicles with veil

Sand yachts
Sailing ships (fixes)
Sailing ships rotary: the rotary sail is a vertical roll of low diameter in fast rotation, of which the effect is to multiply the force of the wind being exerted on him. Ships of this kind actually existed. The navigator Alain Colas and the oceanographer Jean-Yves Cousteau carried there a great interest, each of both demonstrator the desire for being equipped some.
