    Well, this is exciting since Microsoft controlling the climate means that I could potentially destroy the entire world with a tiny bit of code submitted to the heavens. I like it. Let him have his Stratoshield. [insert evil laughter]

    As silly as it might sound, there is a lot of "crazy" ideas being discussed on how to save the planet from ourselves. That is the human way -- continue to live the lifestyle we want, and any problem that comes up we will leave it to the evil geniuses to fix for us. #stratoshield

    Global dimming was also something that was brought up before as well, since the added vapor in the air left in contrails from aircraft create more cloud cover and increase the earth's libido, or albedo, whichever matters more at the time.

    That has some great potential! Now we will just have to wait 4 decades for car companies to actually manufacture them.

    You can't much more efficient than a electric motor (80-90%), and since this uses electricity anyways I don't see why we don't just use electric motors instead.

    @stopcrazypp: Because as efficient as they are, electric motors are kinda shit at providing decent amounts of torque. This supplements a piston based design so that it may even run WITHOUT fuel.

    @Daniel Grinton: wrong. Electric motors produces gobs of torque, starting at zero rpm. The problem with using them in cars is storing the electric energy for use. Pound for pound, gas and diesel fuels have an energy density that is nigh unequaled. Batteries are very heavy and expensive and just don't hold nearly as much energy as a few gallons of diesel.


    Hence, hydrogen fuel cells are seen by many in the industry as a solution to make electric motors more applicable to powering cars.

    Do I simple not get the idea, or is this really as stupid as it sounds. They want to use electromagnetism for the compression/exhaust steps in the otto engine cycle? If all cylinders fire in sync you won't end up with an engine that produces much more vibration? And if they don't fire in sync why not let the crankshaft take care of it, i.e. leave it as it is?

    Many say that Otto engines are far from perfect due to that "slamming back", but this sounds seriously stupid with all the hybrid drivetrains being around that incorporate the perfectly efficient conventional electric engines.

    However, I'm sure someone here knows a lot more about the mechanics of car engines than me, so maybe someone can come up with some arguments for why this is a reasonable idea after all. Guess Gates can afford to hire some competent engineers..

    It matters not a whit if this is a reasonable idea, as long as that guy wearing the brainiac colander in the photo is behind it. Instant venture capital.

    @bosskev: Even without the support of the richest person in the world, if the idea has some merit, and fuel efficiency, which isn't the least important of a car's specs in the buyers' view, is improved, it would likely find a lot of capital. After all, there still are some car manufacturers that have some money.

    @William_III_Earl_of_Dastardshi...: Hybrids are a joke. They add large amount of complexity to a car's system without addressing the real problem - dependence on fossil fuels. The genius behind this is that it allows the combustion process to act as a fuel cell. This is one important step towards a vehicle that can take power from more than one source.


    As a side note, there's no reason this tech would only be restricted to auto use. If it could be scaled down enough, it could possibly be used for a laptop.

    The second image is the most intriguing to me since the "piston" looks to be free floating inside the cylinder walls. With combustion chambers on both sides (and no connecting rod) the power is actually transmitted to the wheels through electicity. The electricity is generated from the piston passing through the coils of magnets (I can't remember the scientific name for that). Basically its a linear induction motor in reverse. I'm not sure this would be more efficient that mechanically sending the power to the wheels, but it would allow for the car to be entirely driven by electric motors (perhaps in the wheel hubs) but you could still run it on fuel?

    @AmityCachinga: It's not efficient. You would have a gas electric generator running continously to power an electric motor for the wheels. Too much conversion, lots of energy lost especially on a stop&go situation.


    Unless they could put in an "energy buffer" (ie ultracapacitor)a lot of energy could be saved while putting a lot of power on the drive even if it has a low power generator.

    "Theoretically, the piston could operate entirely without fuel, using magnetism on both ends to rapidly repel and attract."
