Could a Tesla turbine recharge electric car battery?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of using a Tesla turbine to recharge an electric car's battery while in motion. Participants explore the potential range extension this configuration could provide, considering the principles of energy conservation and the impact of drag on vehicle performance.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant proposes a scenario where an electric car uses a Tesla turbine to capture wind energy while driving, questioning the potential range extension from this setup.
  • Another participant argues that even with 100% efficiency, the range would remain the same due to energy conservation principles, noting that the turbine would add drag and produce less energy than it absorbs from the battery.
  • A participant expresses confusion about the energy flow, clarifying that the turbine captures energy from the wind, not the batteries, and questions whether the drag from the turbine would exceed the energy gained from the wind.
  • Another participant compares the concept to turbo intakes, suggesting that they can improve fuel efficiency despite producing drag, and questions if the turbine could similarly produce more energy than it consumes.
  • One participant expresses skepticism about the range extension potential and shifts the discussion towards alternative energy sources, such as solar power, and introduces the idea of using a Tesla coil to capture environmental energy.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the effectiveness of the Tesla turbine for recharging the battery. There are competing views on the energy dynamics involved, particularly regarding the balance between energy gained from wind and energy lost to drag.

Contextual Notes

Participants highlight the importance of efficiency and energy conservation in evaluating the proposed system. The discussion includes assumptions about the efficiency of the turbine and the impact of drag, which remain unresolved.

Assuming you have an electric car that can go 100miles at 70mph on a single charge, what kind of range could you get with the following configuration? An electric car that runs off the main battery bank. Vents on the outside of the car funnel air to a Tesla turbine while the car is in motion. The Tesla turbine recharges the cars main battery bank. I'm not asking if the car will run forever, I'm wondering what kind of range extension, if any, would the car get from the Tesla turbine?

Welcome to PF!

Assuming the turbine was 100% efficient, the range would still be 100 miles. A real turbine with a lower efficiency would result in a lower range. Conservation of energy applies: the turbine adds drag and produces less energy than it absorbs from the battery.
 
I don't understand. The turbine doesn't absorb energy from the batteries. The outside wind goes through the vents to turn the Tesla turbine which turns an altenator which recharges the batteries. This is not an idea for a tesla turbine powered car. Its an idea to capture some of the energy from the outside wind and convert it to electricity to recharge the main batteries. I know the vent will produce some kind of drag so are you saying the extra energy required to overcome that drag is greater than the energy the wind speed could produce from the Tesla turbine?
 
On a similar note. Turbo intakes produce drag on a car but the turbo is still able to produce higher fuel efficiency. Don't they produce more energy than the drag removes?? Oh and thank for the welcome. Very nice forum board.

The batteries drive the motor, which drives the car, which creates the wind, which drives the turbine, which drives the generator, which charges the batteries. It's one big circle.

Yes. That's the basic scientific principle of conservation of energy.

A turbocharger is powered by the exhaust gases of the car.

You're welcome.
 
Sigh...thats what I was afraid of. Any chance of significantly increasing range with solar? Just curious, not interested in persuing that scenario. Tesla is more interesting. What about a tesla coil attached to the drive train, That would be capturing free electron from the environment wouldn't it? Ugh. I'd love to go electric but the range limitation just makes it implausible.
