Essentially, you’re describing a perpetual motion machine. But look at the issue Why Don’t Electric Cars Have Wind Turbines? However, you may believe that the turbine would not necessarily provide more charge to the battery than the motor consumed, implying that the automobile would not run indefinitely but would run longer than if you were not utilizing it.
Why Don’t Electric Cars Have Wind Turbines?
It may not be visible, but connecting an electric generator to a load (such as a battery) makes it much more difficult to turn.
You can give it a shot by purchasing one of those hand-crank emergency radios with a rechargeable battery. Turn the hand crank after disconnecting the battery.
It rotates quite effortlessly. Connect a drained battery and turn the crank once again. This time is much more difficult!
The same will be true with your windmill generator (which essentially has an electric generator in the middle).
It will become extremely difficult to turn after you attach it to the battery charger to charge the batteries.
Your windmill blades won’t turn unless you’re moving incredibly quickly, but even then, you’ll be creating a lot of wind drag on the car, which will seem like you’re driving around with the brakes on.
Why bother with the windmill blades, for that matter? Connect your generator to the wheel axle precisely at the center of the turbine.
This is more efficient because you can disregard the terrible aerodynamics of a large windmill on your automobile, but the result is the same.
The generator will operate as a gigantic brake (the same regenerative brakes on an EV). And instead of obtaining MORE range, you’ll get LESS range because there are always losses when converting from one type of energy to another.
Yet, there is one ray of hope for your plan. If you position your windmill so that it faces a VERY strong wind powerful enough to overcome all losses and inefficiencies; you drive slowly enough compared to the wind’s speed (we’re talking real slow here), and you might be able to keep your car going (at least until the wind dies).
Why Don’t Electric Cars Have Generators to Recharge Their Batteries?
Electric vehicles (EVs) are designed to be efficient and environmentally friendly. A common question arises: “Why don’t electric cars use generators to recharge their batteries while driving?” The answer lies in the fundamental laws of physics.
Understanding the Physics:
- Law of Conservation of Energy: Energy cannot be created or destroyed; it can only change forms. When an EV’s battery releases energy to the wheels, this energy is converted from electrical to mechanical form. If a generator is used to convert this mechanical energy back to electrical energy, it cannot produce more energy than it receives due to energy conservation.
- Second Law of Thermodynamics: This law states that energy transfer is never 100% efficient. Some energy is always lost as heat or due to friction. So, even if a generator is attached to an EV’s wheel, the energy it produces will always be less than the energy consumed by the battery.
The idea of using a generator to recharge an EV’s battery while driving might sound appealing, but it’s not practical.
Such a system would not only be inefficient but would also slow down the vehicle.
In essence, trying to use a generator in this manner is akin to attempting to create a perpetual motion machine, which is widely recognized as impossible.
Why Aren’t Their Wind Turbines On Electric Cars?
Potential Wind Problems
While there are challenges with renewable energy in general, there are also special issues with wind.
It’s a temperamental resource, so drivers would have difficulties if wind became a factor. Here are some things to consider.
Patterns Of Weather
Unlike hybrid or electric cars, when using wind, you cannot simply add a battery to the vehicle. It’s difficult and uncertain, especially when the wind doesn’t always blow.
You can see how you wouldn’t be able to drive without air movement if you envision a car with a fan propeller on the rear.
That is an accessibility issue, preventing you from going whenever you want.
Wind patterns have several characteristics that might influence how vehicles perform. Storms are crucial to consider since they can affect wind reliability.
Even though specialists can use technology and data to predict these trends, we are unlikely to be able to use the wind to power automobiles constantly.
Seasons are also important to consider. You’d be able to travel around easily in the winter because the wind is usually fiercest then, but once spring arrived, you’d have to adjust when and where you drove.
Furthermore, because weather patterns vary by state and region, drivers would have to assess whether they could travel to a given place.
Adoption Of Electric Motors
Remember that wind energy for vehicles assumes that each vehicle will have an electric motor. That is already an achievement that the United States has yet to achieve.
Electric vehicles account for less than 1% of all automobiles on American roadways.
How can we expect to explore wind if we can’t make energy a popular alternative to fossil fuels?
Demand For Energy
Estimates of how much power wind cars would require are also important. Every day, Americans consume 390 gallons of fuel.
Many kilowatt-hours would be required to meet the same demand as electric vehicles. When you consider the wind’s unpredictability, you can see how that amount can be intimidating.
As you can see, the wind has restrictions that need to be investigated before renewable resources can be used in automobiles.
It’s not all terrible, though, because the wind is still far better for the environment than any fossil fuel. Still, we need to work out the logistics before proclaiming wind-powered automobiles as a possibility shortly.
Here we conclude all about Why Don’t Electric Cars Have Wind Turbines? Because the turbine would force the car to slow down more energy would be required than the turbine had produced to restore the lost speed. You’d lose power more quickly.
It would also make it heavier (and hence less efficient), and it would be not easy to get into parking lots or garages.
A fixed turbine that uses natural wind to charge a battery would be a considerably superior alternative. You take the automobile to the battery and transfer the stored energy when you need it.
Frequently Asked Questions
Is it possible to power an automobile using a wind turbine?
It’s the world’s first official wind-powered vehicle. It’s a hybrid that runs on electricity and has a turbine on the outside. The turbine generates wind power to assist charge the car’s battery, expanding its range significantly.
Why don’t we use a cruising automobile to generate electricity using a wind turbine?
A wind turbine mounted on an automobile does not generate free electricity. Because the turbine causes drag, the engine needs to work harder to compensate, so instead of gaining free energy, more energy is expended than the turbine collects. There is no way around it; this is simple thermodynamics.
Why aren’t wind turbines used everywhere?
Renewable energy necessitates the utilization of a large quantity of land. Wind turbines must be evenly placed throughout farms. Therefore they can’t be packed into tight places. Solar plants are similarly inefficient and take up significantly more space than regular power facilities.
Is it possible to charge an electric car with a wind turbine?
The most obvious solution is directly connecting your car to solar panels or a wind turbine. This is feasible.
