I don’t know if you will respond, but I have had trouble finding people that can answer some seemingly obvious solutions to recharging batteries that could be used to power a electric vehicle (scooter etc) or whatever.
I am unfortunately required to drive quite a bit. When I think of the energy lost in the driving of a car it amazes me. Here are some questions or ideas: mini electric generating turbines: that could be easily mounted in the front grill etc. that could recharge batteries brake conversion kit- turn your car brakes into hybrid vehicle type brakes that would generated electricity that could recharge batteries
Sun blocking solar shields similar to what people use to keep the interior from heating up (I live in Florida)
So, lets say I buy an electric scooter. Instead of just recharging the batteries using my home plug, wouldn’t it be possible to have some sort of easy system of using my car to charge either a bank of batteries in the trunk, that could then be used to recharge the scooter (easiest solution) or having two sets of scooter batteries and recharging the batteries each time I drive?
I would imagine that this already exists, but when you think of all the energy that is lost involving a car….. kinetic, wind, solar, friction, heat, etc its amazing. I feel that our society is in this black and white way of thinking – using fossil fuels, or using alternative energy. Why not simply harness all the energy that is lost in a vehicle and use it to charge energy storage units such as batteries? In a way hybrids do this, but it is still very inefficient when I hear hybrids getting 40 mpg. There are plenty of gasoline vehicles that get that in Europe, and diesel that get 50 mpg. But if an energy efficient vehicle is completely harnessed, I do not see why 60 plus is not possible. I’m straying from my original question.
I hope you respond
Lots of questions!
Let me address your main points and perhaps this will help on the others. Yes, if you use dynamic breaking you can do some extra battery charging from this waste energy each time you slow or stop a car. All of the battery-electric and hybrid cars on the market today already do this. Yes, if you dark tint your car windows you can reduce the cooling loads, and most cars sold in hot climates already include tinted windows.
However, until somebody can void the laws of physics, anything you do to a car to charge a battery will require more engine power and in turn, more fuel. Adding a “wind turbine” to generate electricity will cause an equal amount of wind drag on the car which will lower the mileage. Adding a battery charger to re-charge scooter batteries in the trunk will not only require more horsepower to turn the car’s alternator to generate this charging energy, but the added battery weight will lower the mileage.
Making a vehicle go 100 miles on a gallon of gas is easy. Just get rid of all the weight, and decrease wind and rolling resistance by making it very small. However, you will always end up with a small flat box having no interior space, no crash safety, no heating or cooling, and with no acceleration.
Since I am asked this type of “free vehicle energy” question many times each year, I have a simple answer that may help you understand the concept of physics involved, and why this never works – Just take your 26″ bicycle and replace the front tire with a 16″ tire, then your bike will always be going downhill and you will never need to pedal!
Hope this helps,
