Energy Is An Essential Part Of

Our Daily Lives and it has huge demand.

In 2002,power generation capacity stood at 120,000 MW which is far below peak demand.

We are not at all depending on renewable resources of energy.

As we know fuels are going to extinct in near future . we need to move on to renewable energy resources.

ENERGY FROM SPEED BREAKERS

Whenever a car slows down, it is dissipating energy through its Brakes.

Power generation from speed breakersThrough hydraulics.

WHY HYDRAULIC ? Hydraulics is used because of their proven reliability and

safety when properly installed.

We are using “incompressible fluid”.• resist compression under heavy load • minimal energy loss is experienced.

Hydraulic fluid operates very well • in a very hot working environment, • sustains its airworthiness viscosity, density & fluid

temperature even if it subjected under extreme heat.

The function of the hydraulic system is to capture and store theEnergy i.e low speed high force impulses and transduce it into ahigh speed rotational motion.

Schematic representation

• With a 3 inch stroke, it will take 10 cars (all 4 wheels) to fill the accumulator to working volume. A constant flow of traffic moving at about 16 km/h will be sufficient to keep the system operating at full capacity.• With vehicle weighing 1 ton pressure exerted vehicle on piston will be p = force x area. p = 1000 x9.8 = 9800 Nmm2 =8000 Nmm2 (excluding losses) Then actuator accompanied by accumulator will increase the pressure To required pressure.• If we manage to make the blade velocity move with 4m/s then with 10

strokes we can produce 0.19 watt.• 300 vehicles running 1 hour on a paddle for 14 hours can generate 80 watts of power.
