Can Self-Charging Electric Vehicles Reach 60mph Using Renewable Energies?

In summary, the car would need to look like the photo below and have no air conditioning, no passenger room, no cargo space and you have to lay down to drive it. It will go 60mph, but it'll take a minute or two to accelerate to it. That's for continuous driving. Either that or like mfb says, you can have a normal car that you can only drive an average of a couple of miles a day.

Would it be possible to engineer a self-charging vehicle... Harnessing kinetic, solar, and wind energy?

Not enough to be perpetually self charging unless you only drive it a few miles a week. For continuous driving you can't come close without major sacrifices.

You cannot violate conservation of energy. Harnessing kinetic energy doesn't work because you need the motor to gain that kinetic energy.
Wind and solar: Possible in principle. In practice the power is way too low to power a regular car that way. You don't want your car to charge for a week just to make a short trip possible.

What sacrifices??

A typical electric car will need something like 200 Wh/km at typical speed mixtures. If you cover 2 m2 with solar panels, and you live in a sunny area, you might get 2000 Wh per day, or 10 km of driving distance per day - but only if the sun shines.
Want to drive somewhere because it rains? Better hope you had good weather and didn't use your car the days before.
Want to drive for more than 100 km at a time? Then you have to charge for weeks and you'll need large, expensive and heavy batteries.

Wind would be even worse.

I think I see some foolishness in that photo, Russ. ?

Shouldn't the guy taking pictures have a PV system on his hat to recharge his camera battery ?

... and I'll bet Volkswagen is trying to cheat, too ?

Wait!... on second thought...

The world record for a vehicled powered only from PV (no batteries) is not quite there yet, 55 mph. No doubt the course was dead level with no headwind and the time close to solar zenith.

Add batteries and and the top speed is indefinitely higher, forcing the solar car competitions to use long distances to avoid nonsensical outcomes.

Related to Can Self-Charging Electric Vehicles Reach 60mph Using Renewable Energies?

1. How does a self-charge electric vehicle work?

A self-charge electric vehicle uses technology such as regenerative braking and solar panels to generate and store electricity, which is used to power the vehicle's motor and recharge the battery. This allows the vehicle to be driven without the need for traditional refueling methods.

2. What are the benefits of using a self-charge electric vehicle?

Using a self-charge electric vehicle can have several benefits, including reduced emissions, cost savings on fuel, and less dependence on traditional fuel sources. It can also potentially reduce maintenance costs and improve overall energy efficiency.

3. How long does it take to charge a self-charge electric vehicle?

The charging time for a self-charge electric vehicle can vary depending on the type of technology used and the size of the vehicle's battery. In general, it can take anywhere from a few hours to overnight to fully charge a self-charge electric vehicle.

4. Can a self-charge electric vehicle be used for long distances?

Yes, a self-charge electric vehicle can be used for long distances, although the range may be limited compared to traditional fuel-powered vehicles. However, advancements in technology are constantly improving the range and capabilities of self-charge electric vehicles.

5. Are there any drawbacks to using a self-charge electric vehicle?

Some potential drawbacks of self-charge electric vehicles include limited range, higher upfront costs, and the need for access to charging infrastructure. Additionally, the electricity used to charge the vehicle may still be generated from non-renewable sources, although efforts are being made to increase the use of renewable energy in the charging process.
