Bill Gates Patents Plasma Injector for Your Car

April 12th, 2009

Bill Gates’ vision is part of most home PCs, laptops, netbooks, and even cell phones with the Windows operating system. Now he wants to redesign how cars work.

Earlier today, a patent filed with the US Patent & Trademark Office was made available for public viewing, detailing an electromagnetic engine that could very well replace the traditional combustible engine, paving the way to energy efficient automobiles of the future. Among the ten inventors listed in the patent–as Searete LLC, part of Intellectual Ventures–is none other than Mr. Windows himself, William H. Gates, III, and Microsoft’s former chief technology officer, Nathan Myhrvold. The group originally filed the patent back in October 2007.

As the patent states, the electromagnetic engine “converts mechanical energy of a piston to and from electrical energy during each piston cycle.” However, the group also applied for two additional variants of the concept: free-piston and opposed-piston. While the free piston patent uses the same definition, the opposed piston electromagnetic engine is defined as an “engine [that] includes a cylinder having a two pistons slidably disposed therein, a port arranged to admit a reactant into the cylinder between the two pistons, and a converter operable with at least one piston to convert mechanical energy of the piston to electrical energy.”

While the patent mentions a “reactant,” that doesn’t necessarily indicate fuel used today. The patent talks about a liquid reactant injector and a carburetor that would deliver the reactant mixture to the first port of the engine. Another interesting note was the patent’s use of a “plasma injector,” a terminology widely used in the Star Trek universe. This device–whether its in the form of a spark plug, catalyst, particle beam igniter (that’s in there too), or the plasma injector– is referred to as a reaction trigger, an electrical igniter configured to initiate a chemical reaction in a reactant disposed between the first piston and the closed end of the first cylinder; the reaction trigger is located at the top of the cylinder.

But how does this engine actually work? The electromagnetic engine apparently doesn’t need alternating pistons, but rather a set of pistons fitted with electromagnets to speed up the recovery process. With magnets on both ends, the piston is pulled up and down the cylinder. Once the piston reaches the top and fires, it is immediately pulled back down into the cylinder by magnetic force, and then repeats the cycle. According to the patent, the pistons can use either electromagnets, permanent magnets, or a magnetically susceptible material such as an iron core. The energy generated from the reaction trigger could be stored in a battery, capacitor, or some other energy management system.

With that said, there’s a good chance an automobile using this type of engine will run on electricity and utilize a rechargeable battery. If the engine is capable of storing energy as the patent suggests, the automobile may not even need an alternator. That may be incorrect of course, however, there’s no mistaking that Bill Gates is once again trying to change how things work in everyday things: first with DOS, then Windows, and now with the electromagnetic combustion engine.

Audi 2009 S4 test drive in Majorca

December 9th, 2008

Majorca, Spain – You simply can’t have enough of a good thing, especially if it’s an Audi. The A4 was recently voted the 2009 Best New Luxury Vehicle in Canada by members of AJAC. Last month, Audi gave auto writers their first drive in its even more athletic sibling the new Audi S4.

While they look alike, the faster and more agile S4 and S4 Avant, its wagon-bodied edition, are the gifted jocks in the A4 family. A new supercharged V6 engine replaces the outgoing V8, plus Audi also has come up with new and clever ways to convert power into rapid, yet very stable, vehicle motion.

The new 3.0-litre TFSI engine combines direct fuel injection with a low-pressure supercharger. It can produce 333 horsepower, yet fuel consumption is surprisingly low. An official Canadian fuel rating, however, has not yet been established.

At the heart of the S4 is Audi’s brilliant Quattro permanent four-wheel-drive system that now sends 60 per cent of drive power to the rear wheels, during normal operation. A six-speed manual transmission is standard and a new seven-speed S Tronic automatic is an option.
New engineering tricks start with Audi Drive Select. The driver is given three driving-style choices that alter the working modes of the engine, the S Tronic transmission and a new optional Sport Differential.

In the “comfort” mode, safety and stability are priorities along with optimal suspension damping. The “auto” mode is a balance between all functions. And the “dynamic” mode emphasizes agility and the dynamic effect of the new Sport Differential.

The Sport Differential is actually a conventional differential with additional clutch packs and gear seats on each axle. An electro-hydraulic system is used to engage a clutch pack and this can increase the wheel speed of that axle by up to 10 per cent.

I got an opportunity to play with this system on a race-track, while on the island of Majorca. Heavy rain during our one-day stay in Spain (on a plain, wouldn’t you know) actually added to the driving experience and gave me a better appreciation of the Quattro drive and Sport Differential systems.

The Sport Differential can accelerate an outside rear wheel in a curve primarily to counter understeer (a tendency to run wide). The torque intervention enables the S4 to retain directional accuracy by “forcing” the car into a corner.

An advantage of supercharging over turbocharging is that the torque boost is immediate at low engine speeds. Maximum torque of 325 lb.-ft. is available between 2,900 and 5,300 r.p.m. The S4 can sprint to 100 km/h in just 5.1 seconds and it has an electronically governed top speed of 250 km/h. As already mentioned, the surprising part is that its fuel consumption has also been reduced, by 27 per cent, according to Audi.

Quick facts about the new Audi S4:

  • New 3.0-litre TFSI engine with mechanical supercharging delivers 333 hp and 324.53 lb-ft of torque.
  • Zero to 100 km/h in 5.1 seconds and it has top speed of 250 km/h (governed).
  • A 27 percent lower fuel consumption – combined estimate 9.7 L/100 km.
  • Six-speed manual gearbox as standard and an optional seven-speed S Tronic automatic.
  • Quattro permanent four-wheel drive with new rear-biased characteristics.
  • Optional sport rear differential.
  • Sports suspension with firm settings, optional Audi drive select dynamic driving system with adaptive damper control and dynamic steering.
  • High-performance brake system with large discs and black callipers.
  • Standard 18-inch wheels and optional 19-inch wheels.
