    You have big oil in direct competion, you know who won, its history. Nope its been proven by hundreds of people on a small scale and the scale that tesla was working with would cost upwards of billions today to reproduce because the actual transmission media is the earth and huge grounding rods are required to be dug in very deep in the water table.

    I dont know why you would say theory unless maybe you do not know that IEEE is?

    Well, for now, from a practicle use standpoint, it is still theoretical is all I'm saying, which is why I included the bit about we should have been researching/developing over the past century+.

    thats like saying a boat is not practical because you are not surrounded by them or there are none in your area. everything tesla did works, why you would think wireless transmission of power is not practical stymies the mind.

    Well, were it practicle, we'd be seeing it power vehicles now.

    I'm not saying abandon it, made that clear with the bit saying we should have beenR&Ding it for the past century

    it was practical in 1900 too, so where the hell are they? you are using flawed logic.

    It was proven & demonstrated that it could power vehicles for practicle purposes in 1900?

    You have a link?

    Do you have any comprehension of scale?

    small source for small cars big source for big cars, not much of a stretch.

    I have little patience for people now days who have little to no comprehension of the topics they engage in. find your own link, tesla remote controlled boat 1889.

    That's kinda funny. Apparently you don't comprehend practicle.

    My first reply to this line we're in, stated I'd research it further. Admittedly, due to IRL stuff going on right now for me, I haven't had the chance.

    Anyway, good chat.

    Id say more like you dont since its highly doubtful you have any idea what is required to pull it off yet you believe its not practical with no evidence to support your belief.

    As long as your 'now' is hypothetical that 'all cars are electric' it's kind of silly to leave out the other hypotheticals like greatly improved battery technology, like hybrid electric technology, like charging stations everywhere, like auto-charging through the road systems? Or why not hypothesize 'all' the cars are self-drivng and therefore can be more efficient and travel at much higher net speeds? Why not talk about an electric vehicle not needing to wait in hours-long gas station lines? So I have no problem imagining only electric vehicles 'now' but this must also be accompanied by imagining very efficient electric vehicle technologies and infrastructure...

    L M A O!

    I reviewed YOUR provided evidence, for YOUR claim.

    I see no practicle application for it, as it stands, in doing so.

    I've seen a few concepts for a Gasoline-Electric hybrid. Basically it's a gasoline turbine engine that spins an electric generator.

    Fuel economies were measured in Hours per Gallon and were pretty up there. Last one I heard about (forgot which TV show mentioned it...sorry) was getting three quarters of hour per gallon. So with a standard 12-gallon tank, that's 9 hours of operation and if you're doing highway speeds (say 65 MPH) that's 565 miles of range.

    Not too shabby and would make for a good bridge until recharge times and battery capacities can provide the range/charge times we need to get really viable.

    That's not what he is saying. He is saying that a diesel generator is versatile and in an emergency, you can consider alternative fuels. When everybody is fleeing a hurricane and the gas stations are empty, you can go to a grocery store and get a few gallons of cooking oil.

    The generator for a series hybrid can run at a constant rpm and be tuned for maximum efficiency and minimum noise. It can be turned on or off automatically or manually to improve efficiency. If you know you are a few miles from home, you can switch off the generator and charge at home for about a nickel/mile. It also only needs to be large enough to meet the average power demand of a car. 15-20 hp should be enough. The work is all done by the electric motor.

    like I said I have little patience for people with no tecnological background that are in over their heads. my advice is to get a degree in EE first then come back and continue your attempt on discussing feasibility.

    first off you wouldnt want to use a diesel or any ICE, you would want to use an ECE resonant stirling design for maximum efficiency and they can burn wood and anything thats laying around like road kill and other peoples car seats etc LOL.

    Maybe you should get an EE and get back to me on how that works.

    What about roads that charge the vehicles? Like the old race tracks we got whooped with? LOL I'm being serious though.

    then you may as well simply mount a generator on the car, and good luck with ever increasin entropy.

    "
    Dr. Leonardo Gasendo, a United States (US)-based chemical engineer who graduated from Adamson University in 1950, has been granted a patent for his Long Distance Electric Vehicle (LDEV).

    Gasendo said the LDEV uses two on-board battery chargers that convert wheel vibrations and cruising speed into electricity for charging the onboard battery.

    “Going downhill, the LDEV will convert the earth’s gravity into electricity for charging the onboard battery with zero consumption of electricity. It will travel 1,610 km without exhausting the electrical charge "

    They already do that on decel or coast, its called regen. Have to say the bumps idea is a really good one the rougher the roads the better. LOL That would work well, but I'd be curious how much power youd actually get from the bumps, I am not sure its worth the infrastructure required to achieve it. I suspect only a couple percent tops?

    Another one that could be a real payoff would be using the wind resistance of the vehicle moving through the air the same way so when you are pushing a tough wind but I cant imagine what kind of contraption could be designed to accommodate it.

    His design is pretty ingenius, I like it, but not sure how stable is is because first blush looks like its a floating platform?

    You know the more I think about the better it sounds, your tires are constantly bouncing around even on relatively smooth roads.

    You just keep giving "witty" responses and try to make yourself look smart by insulting people.

    Why don't you explain to me how it works, how it will be safe with an open flame in a moving vehicle, how far it can get on a "fill up", and what the emissions will be like? I've seen steam powered cars that run on firewood. How would your suggestion be any better?

    My suggestion is over 80++% efficient and it charges the battery and is not part of the drive train. Dont blame me you chose to 'argue' topics above or outside your knowledge base.

    Now if your name was Leonardo Gasendo you would have just recieved a compliment from me, but its not.
