Do you think wind turbine fitted on a car could work?

Friday, February 5th, 2010

Can it produce enough energy to power the radio, charge your laptop etc.?
Is it practical and worth it?
Do you want to install it on your car? Please state your reason.

it would produce considerably less power than the drag it caused, which would increase fuel use.

so no, i wouldn’t like it.
(It is cool to think about however. :-)

and, as warren said, it’s effectiveness would be very wind dependent.
freeway might be okay.
around town — not so much.
but still, in total, an energy waster.

 

Can a wind turbine placed on top of a small electric vehicle (100kg) charge a battery to drive the car?

Friday, February 5th, 2010

is it feasible to charge the battery with wind turbine instead of solar panels. would i get enough power from the wind to charge the battery? or the DC motor driving the car would consume all of the battery charge before it will get charged from the wind turbine??

what about the wind powered cars?!! www.windturbineracer.com
the cars move with only wind energy.why can’t we convert this energy into electricity to drive the motor?!!

Noway. The car would experience more drag. The energy of the wind turbine is far too little to charge the battery that would be fully exhausted in the end.

 

What is the exact definition of a Hybrid Car?

Friday, February 5th, 2010

I need to know what a Hybrid car is for a bet. Is it a combination between a Car and a SUV or is it the combination between a fuel and electric engine?

Thank You.

Super Solar Shower

No more cold showers when you’re camping. This low-tech invention uses solar energy to heat water for all your washing. Large 4-gallon capacity provides ample hot water for at least three hot showers. On a 70 day the Solar Shower will heat 60 water to 108 in only three hours. Great for camping, car trips or emergency use. Taiwan.

Play Smart Car

The “”kids”" who work in our office loved this amazing play car. Yours will, too! Like today’s energy-efficient hybrid engines, it harnesses inertia, centrifugal force and friction to propel riders into a world of fun. Free of batteries and pedals, just rotate the steering wheel from side to side and move forward or flip it 180 to go in reverse. The smoother the “”road,”" the faster the ride. But don’t worry; it won’t exceed a child-safe 6.2 mph. Supports 220 lbs. on smooth surfaces and 120 lbs. on rough surfaces. Assembly required. For ages 3 and up.

Can a wind turbine placed on top of a small electric vehicle (100kg) charge a battery to drive the car?

Wednesday, February 3rd, 2010

I want to do this as my BS project in mechanical engineering. i need to know if its feasible to charge the battery with wind turbine instead of solar panels. would i get enough power from the wind to charge the battery? or the DC motor driving the car would consume all of the battery charge before it will get charged from the wind turbine??

what about the wind powered cars?!! www.windturbineracer.com

Well, you can’t have a perpetual motion machine, as in the air flowing through the turbine is due to the forward motion of the car, sending power to the motor for forward motion.

But a wind powered car is possible.

How can i make a wind powered car out of a milk container?

Tuesday, February 2nd, 2010

I have a scool milk container. How would I create a car? My teacher will have a box fan in the back to blow, but that will be the only energy pushing the car. The car must have a axile, its own wheels, it can’t be sitting on top of another car. What can I do?

add wheels and a model plane propellor powered by an elastic band,.
