Yoshimar Lopez asked the Naked Scientists:
We have a ramp in puebla, mexico of 10 mts long 8 mts wide. The car that circulates there is precisely of 1910kg and it circulates 645 times through the ramp on one way and 645 times through the ramp on the other way. So we have cars of 1850kg that will step on the ramp 1290 times a day with an average speed of 15km/hr.
The Energy generated will be inyected to the power grid (grid tied). Wich could be of 1 phase 110volts ac. Or 3 phase 220volts or 1 phase 220volts or 3 phase at 440volts ac. 60hz. Any of those could be useful.
We would need the following:
Kwh generated by day.
What do you think?
-
The amount of energy produced each time a vehicle traverses the ramp is very small and the idea that it could be fed into the grid in real time would be a horrendous technical problem.
the best you could do is to store it in some way ,gravity, chemical or flywheel and feed it into the grid when the value of power is high.
The cost of the equipment to do this would be out of all proportion to the monies raised by selling the power.

It all depends on the vertical deflection of the ramp, which is not stated. In any case, it would be more efficient and a lot safer to burn the gasoline in a stationary motor-generator.
