    Hey give the man a ceegar!!! Good point, wish I had of thought of that one!


    I suppose that will be the next logical step, now I wonder why all those dumb engineers didn't think of that too?

      These over unity systems are flat dangerous. Any time you arrive in the parking garage at work with more on-board energy than you left home with is a recipe for disaster. Why, imagine the hell to pay driving I-90 from Seattle to Boston and then getting hit by a bus full of school children there. The accumulated energy after that drive should be in the peta joules. You could blow a hole in Boston the side of Manhattan.

        Imagine no more oil changes or repair bills (except shocks, brakes, and tires). Imagine stable pricing that doesn't fluctuate $0.60 per gallon because someone farted in the middle east.
        You missed a few major points. It would be nice to own a pure (non hybrid) EV, but most folks simply dont have the power supply in their home to charge one. It doesnt really matter if the grid supply exists if you cant plug the vehicle in and make it charge.

        Beyond that, owners MUST change their batteries every few years, and other costs are insane as well. On mine, there is a recommended 3 year/36k mile battery change. 27 Nimh batteries = ~$6k a few years ago, which is why mine is part of my "collection" and not currently licensed. 3 battery changes in 100k miles = more $$$ than the fully loaded gasoline vehicle cost new. If you consider a significant loss of payload for a commercial vehicle (~1/3 in many cases), the cost adds up ridiculously quick.

          Looks like that old Chinese farmer is smarter than everyone is giving him credit for.
          He's got a nice little electric car that he's able to pick up cute dunces with.
          If she believed the fan/generator story...well he's probably got the ball rolling by now.

            Of course the Article is stupid,they are talking heads not engineers after all.It's comparing Apples and Oranges.

            First off it's not a car in the modern sense,it's simply an electric go kart.He stuck a window fan and a PM motor on the front as a half arsed range extender.It's pushing air out of the way,so why not have that air spin a generator and recouple some of the loss?Whatever,it's no different than the EV guys here adding a Honda generator to the trunk to top off while at work when they need to range more than 25miles from home.
            He's got no roof,no seat belts,probably no floor boards,no AC,no power steering,no cup holder or seat warmers and I didn't see a Heater either.It's a four-wheeled electric Moped

            Now lets look at the EV's produced by the major car companies.All are failures either in technology,sales or both and some are downright frauds committed on the taxpayers.
            The Volt-production suspended,more units were sold between dealers than to the general public.
            Nissan Leaf-less than 1,000 sold in the last 6 months
            Ford Focus electric none sold in the last quarter.
            The Fiskar-where did our money go and why is it on fire?

            The Chinese guy needs some capital,I say give it to him.For another $40 he can add a roof and some Chinese solar panels and extend his range even farther.It still won't be a car,but it will still beat walking and would easily out sell his competition
            I just need one more tool,just one!

              I think you may have missed my point, it's not the vehicle itself it's the concept that's just plain dumb. But of course the real point was not even the car it was the question of why on Earth did it rate a news article by a major news organization?

              Because the fan would add far more total drag compared to just a normal frontal area than the generator could compensate for, he is not taking advantage of wasted energy he is in fact attempting to use energy to make energy. This is the usual pitfall when some would-be inventor attempts to build something like this, I guess the reasoning is that since the wind would be blowing over the car anyway why not use it to produce power? They don't seem to understand that the spinning fan adds as much or more drag than a flat disc of the same diameter, in fact there would be far less drag if the blades were locked and not allowed to turn.

                The concept of an electric car itself is nothing more than a novelty,it's been attempted since what 1890?Still in the realm of tinkerers and rich folk who want a play toy.

                And it made the news the same way every puppy down a well,idiot who tried to drive through 15' of raging river in a Toyota or fast food joint burning down.People are bored and there isn't much else to report.

                Of course the fact we are talking about it here says what about ourselves?

                  Sheesh.....

                  people are ACTUALLY DISCUSSING this? As if there was anything debatable here?

                  it isn't about "pushing air out of the way"......or any other such horse hockey It's WAY simpler......

                  "Energy balance".....

                  If you move a wind turbine through the air on your car fast enough to make electric energy in its generator, you have to EXPEND ENERGY to do that.....

                  And, you have to expend the total power the generator produces, PLUS all the losses, AND you still have to expend the energy to move the car as well.

                  So, the generator produces 80 or 85 watts... which you have to supply in addition to moving the car.

                  The generator LOSSES amount to maybe 15 or 20 watts, which you ALSO have to supply.

                  When you add that all up, you have to put in 100 watts to the system for every 80 or 85 watts you get back. Plus you still have to move the car.

                  net result is that you LOSE MORE power than if you didn't have the silly generator and "fan".

                  You'd have better distance if you threw the fan etc into the trunk, or better yet, the ditch.

                    I hate to break the news to this Chinese guy since he's so excited and to Fox being so far behind the curve, but great minds and scientists pushing the envelope are on the verge of unleashing unlimited free energy. These guys can explain it much better than I can.

                    In fact, I can't seem to explain it at all. My sister buys into this and I can't seem to make any headway pointing out the paucity of real support or concrete information other than the assertions that "this is true".

                      Bit of a crock to kick only Fox when it is being trumpeted around the world by news agencies, globally. Better to say "par for news reporting". It probably indicates a quiet news day and nothing more.

                        I think you were supposed to tell from the silly music that they think this car is silly as well.

                          I would like to point out that this is a fraud website (in case that was not already clear). You can tell by the structure of the articles. They start off by saying things that are true, then saying things that are true, but not relevant, then saying things that are vague, then saying things that are false, and finally ending with making stuff up.

                            Imagine never having to stop at a gas station again. Imagine no more oil changes or repair bills (except shocks, brakes, and tires). Imagine stable pricing that doesn't fluctuate $0.60 per gallon because someone farted in the middle east.

                            Then there's the fact that electric cars give you torque on demand, not after you've waited for your engine to hit it's power band past 4k rpms. Or the fact that the traction control reacts 1000x faster than on an internal combustion powered vehicle.

                            Disclaimer: I do not own an electric car, they are still to expensive. However, I drove a Tesla Roadster and it completely changed my mind about electric vehicles the instant I pressed on the accelerator. There's no more VROOOM of the engine, it's more like a ZAP and you're gone. I also like how my wife described it, "it's like driving a laser beam".
                            Something about having #2000 of hazardous material in every car, the inability to just pull in and fill up, the need to have even more electronics on a vehicle turns me off. I personally don't need a lot more power than our tdi jetta has and 13 gallons of diesel takes me into 600 miles pretty easily. I would rather change oil than batteries.....the kicker is, I live where you could drive all day and never see a power pole or gas station....I can carry spare gas.

                            We get 3 foot snow storms most years, I still have to drive 28 miles to work.

                            Now were I to be where I lived inner city, I could see it your way. But out here, electric cars better have a backup plan or stick to town.

                              Jerry,we all already know this,it's just a Wednesday night nothing to do post/reply thing here.

                              Electric cars are the textbook definition of insanity.You know the one repeating the same experiment over and over and expecting a different result?
                              Well to expand on that there is actually a result.The experiment becomes increasingly more expensive.

                                Unfortunately it seems it's that way and very well may be destined to stay that way.

                                My cousin is into all kinds of nonsense and is often calling me (another guy sent me the link to the car however) with "proof" that some of the ideas he talks about are in fact possible, he is always trying to show me the newest "free energy" device and fully believes that big oil is behind keeping this technology suppressed. It's amazing just how many people cannot understand that it is impossible for a generator to produce more power than it takes to run it or that electricity cannot be simply "stepped up" (increased Wattage) by some kind of solid state device. The local power company a few years ago went around to shopping centers with a demo set up that was aimed at educating people on energy conservation, it was simply an exercise bike with a small generator connected to a series of 100 Watt light bulbs and people were invited to pedal the thing while the attendant progressively turned on the bulbs. A lot of people, most in fact, were shocked (sorry, pun intended but I couldn't resist that one! ) to see just how much effort it took to power just one 100 Watt bulb, never mind three or four, but even more shocking (ok I won't do it again, ) was that most people simply could not understand why the bike got harder to pedal as more lights were turned on!.
