    Everything is not limited to considering just consuming energy. I know about the laws of thermodynamics. There are further features about the compressed-air propulsion. Reducing the pressure on the batteries, having their particular advantages, … I know their efficiency is 14% and the efficiency of the electric motors is 98%, but I think that system needs to be kept …
    I gain electricity by braking: regenerative, piezo, hydraulic, inductive, and thermoacoustic. As a coincidence, the electricity of grid (stored in batteries), sun, and rotating a handle is being pumped into the motors. How do I coordinate all these? I need to apply some electronics, circuits, …
    I meant damaging the tanks and other components, otherwise it's more attractive than batteries to charge a compressed-air tank during 3 minutes, much faster than any present battery. If you use manual compressors or compress the air gradually, that's OK, but if you do it fast, you should be careful.
    That's not so. Look at these cars separately. I assure you there is no innovation of mine about this. I respect the experiences of the auto makers which all of them have not been bad tradeoff.
    I'm telling we should apply useful complexity/simplicity, not useless simplicity/complexity. Grid, and solar are natural, bio-force devices won't be more than 10-15 kg, treadmill is a damn simple tool and you can use it even at home, windmill has nothing to do with the car, it's the government's business, cooling tools are already working in the hybrid/electric car. The compressed-air system is a bit problematic but not too much. The only complicated system is the solenoid electricity that could result in the most amounts of power …
    Actually, I didn't expect such a volume of objections to my plan. I thank all and I learned many points from you. Therefore, my document surely needs newer versions. I concluded the compressed-air tanks and battery packs should be away from each other.

    Please understand that this board is flooded with woo woos, nutjobs, Einstien wannabes, narcissists and all forms of crazyness proposing their theories and ideas. Don't take our criticism personally. Iron sharpens iron.

    Don't limit me on this very improbable example. Of course I would do at first what you said. You have nothing to say about the other quoted points? You're right about this, but disregarding this special case, you didn't object with whole of this method. It's good.
    The solenoids do not move at all. Read that section again to understand it.
    Maybe I should draw a schematic figure of that. Besides some calculations, etc, … I can't reply you for now, another time …
    Me: I accept this method is weak
    You: you completely ignored the fact that sound waves produce very little energy
    What's the matter? I know the sound waves are not atomic bombs. I have no interest to claim more than needed. I put two links for you from a British website about a related project. Read them if you want to know more.
    I am not so sure about the current technological capabilities of this item. Once again, you just emphasized on one corner of my remark. Only cabin & its nearby points. I pointed out tanks, tweels, … as well …
    You are quite right. I completely agree this: Iron sharpens iron.

    The human body is very limited on the amount of power that it can produce..compared to the amount of power required to move a car..adding "biopower" to the equation is irrelevant.
    Solenoids have to move to produce power. The body of a car doesn't move enough to generate enough power to be useful. Where does this movement come from?
    Please do..because your proposal of extracting a meaningful amount of power from the piezoelectric effects of the movement of a car chassis doesn't make sense.
    So you could consented that this method was impractical..but for some reason..you hold on to it.
    While I said your idea of extracting energy from the difference between the cabin temperature and the outside temperature was impractical...I still think this idea can be utilized with other higher temp systems.

    I'm glad to hear you say this..as an engineer...I want other engineers to point out the flaws in my design that I have overlooked...in the end, it makes for a better design.

    Charge/discharge efficiency of li-ion batteries at a .1c charge and .5c discharge is actually close to 90%.

    Agreed, that is a fast method of charging. But again, that's a huge amount of hardware (tanks, piping, refrigeration systems) to get an additional 20 miles (optimistically) of range. Is it worth carrying around 500 pounds of hardware to occasionally get a 20 mile range boost? Wouldn't it be more worthwhile to put that carrying capacity into more batteries, or a combustion engine that can supplement the batteries? That would give you a lot more than 20 additional miles of range. (And the larger capacity battery means you can get X miles of charge that much faster.)

    Agreed!

    Well, but your criterion is "useful complexity." A set of pedals will give you 100 watts, tops - and that's for a passenger who is willing to sweat hard in the closed environment of a car. And your gain? About a mile out of a 60 mile range. You will gain more range by not taking a passenger at all and saving the 170 pounds of weight.

    Not at the levels you're talking about. Providing 20 miles of range via compressed air is going to require a refrigeration system far, far larger than one intended to cool four occupants of a car. You could do it externally; have coolant lines that run alongside the compressed air hose. But again, that's complexity that most gas stations won't bother with.

    The "solenoid electricity" system is pretty easy to convert to usable power. The hardware is off the shelf. You're just not going to get any power out of it; you can't harvest power that isn't there.

    Prove this to yourself. Get one of those shaky flashlights you mention and mount it in a car somewhere. See if the LED ever comes on. If it does, you've got about 30 milliwatts. Then connect it to a volt and amp meter and record how much power you get. I think you will find that no matter where you mount it the amount of power generated will be effectively zero.
