This Is Mind Blowing...

In 1994 Japanese researchers at Nippondenso Co., Ltd. fabricated a 1/1000th-scale working electric car.2351,2352 As small as a grain of rice, the microcar was a 1/1000-scale replica of the Toyota Motor Corp's first automobile, the 1936 Model AA sedan (Fig. 2.1). The tiny vehicle incorporated 24 parts, including tires, wheels, axles, headlights and taillights, bumpers, a spare tire, and hubcaps carrying the company name inscribed in microscopic letters, all manually assembled using a mechanical micromanipulator of the type generally used for cell handling in biological research (Chapter 21). In part because of this handcrafting, each microcar cost more to build than a full-size modern luxury automobile.

The Nippondenso microcar was 4800 microns long, 1800 microns wide, and 1800 microns high, consisting of a chassis, a shell body, and a 5-part electromagnetic step motor measuring 700 microns in diameter with a ~0.07-tesla magnet penetrated by an axle 150 microns thick and 1900 microns long. Power was supplied through thin (18 micron) copper wires, carrying 20 mA at 3 volts. The motor developed a peak torque of 1.3 x 106 N-m (mean 7 x 107 N-m) at a mean frequency of ~100 Hz (peak frequency ~700 Hz), propelling the car forward across a level surface at a top speed of 10 cm/sec. Some internal wear of the rotating parts was visible after ~2000 sec of continuous operation; the addition of ~0.1 microgram of lubricant to the wheel microbearings caused the mechanism to seize due to lubricant viscosity. The microcar body was a 30-micron thick 20-milligram shell, fabricated with features as small as ~2 microns using modeling and casting, N/C machine cutting, mold etching, submicron diamond-powder polishing, and nickel and gold plating processes. Measured average roughness of machined and final polished surfaces was 130 nm and 26 nm, respectively. The shell captured all features as small as 2 mm on the original full-size automobile body. Each tire was 690 microns in diameter and 170 microns wide. The license plate was 10 microns thick, 380 microns wide and 190 microns high.

SEE????????????????????????????????

How F****** clever is that??????????????????

Last time i worked with something that small, i was zipping it up!!!! :duh:

You know the toyota main dealer still quoted £300 a service.

Apparently on hearing the news gordon brown rushed in a new road tax, £80 for 30 microns and above, £70 for 15 microns and above.

---------------------

The greens rushed out a statement today saying they were outraged that cars would now be polluting the minature world as well as our. Their spokesman said today.

--------------------

"EVeryone knows that in the micron world a bike is much more environmentally freindly means of transport. The exhaust from one of those is at the level of bacteria, and who knows how they could be affected"

-----------------------------------------

Wandsworth council denied claims that one of their eagle eyed wardens had slapped a parking fine on the car, for illegal parking in a designated rice zone.

Any chance the alignment is correct ?

I reckon with the right air filter and engine remap you could gain another 0.1 x 106 N-m of peak torque. Now that's a bad boy.
