Urban Kinetic/Electric Vehicle
I have plenty of ideas popping up, but as usually, the everyday work doesn’t give me any time to develop or even construct and test my ideas, so I came here to share it with you all.
Today I am going to talk about an Urban Kinetic/Electric Vehicle concept.
As we are all aware (or at least many people here at TED), the energy consumption must be lowered, to ensure a better future for all the people on earth.
Therefore I have upgraded the common Electric car with a kinetic energy storage system, or simply said, with a big flywheel.
The point of this idea is, to be able to use low cost gel batteries and mount them into a rotating array, and therefore use their WEIGHT not only for electric, but also for kinetic energy storage!
This would create a big and heavy flywheel, that would be mounted behind the front seats of the car, above the rear drive axle.
And this is how it should work:
1. When you start your daily commute, the flywheel is stationary and all the stored electric energy is used to get the car into travel speed of lets say 50 km/h.
2. When you are approaching the first red light in the city, then instead of heating up the brakes, you decrease your speed and transform it into the rotation of the flywheel and so you store the most of the previously used electric energy into kinetic energy.
3. When the green light lights up, you push your “gas” pedal and the kinetic energy of the rotating flywheel is automatically transferred onto the drive axle, and the car will start accelerating with very little
stored electric energy used.
I think, that this concept has a potential, to dramatically increase the “in city” travel energy consumption.
What are your opinions?
Can somebody do the math and the physics to check if my assumptions are correct?
I have the knowledge to design and maybe also build a prototype, at least a small one for concept proof, but I would like to see some calculations first and hear some good opinions.
