Why the WDG Might Put Traditional Engines to Shame
So at its basic level we have an internal explosion that produces energy that moves a mechanical system that can be used to move a car. Been there, done that. So how does the WDG actually improve on what we're currently using? Only by being a billion more times efficient, smaller, lighter and better for the environment. Alright, maybe not a billion but it's a lot, you'll see.
Like we said earlier, we can scrap the pistons, tranny, valves, crankshaft, cooling system and so on. We're saving a boatload in weight when we do this. Thirty percent to be exact and less weight helps us save fuel, which lets us go further. If we use the WDG, our vehicles could be 60 percent more fuel-efficient [source: ARPA]. At the risk of sounding like an infomercial: But wait, there's more! We're also going to reduce C02 emissions by up to 90 percent because the generator is more efficient with its fuel than traditional engines [source: Loveday].
So there you have it; a fuel efficient, lightweight generator with hardly any emissions. All this adds up to a propulsion system that's 3.5 times more efficient than current hybrids and 5 times more efficient than internal combustion engines [source: Loveday].
Oh, there's just one small thing. Nothing to be concerned about, really. It's just that we don't really know if...well, if it'll work on a real car.
