Worlds smallest drag racer- only drives on streets paved with gold

Big fat bucky-ball rear wheels with smaller p-carborane front wheels give it extra traction for better acceleration to it's top speed of 9 nanomiles or .0005 inches an hour.

that means it does the 1/4 mile in about 3633 years breaking the previous 1/4 mile record by some 300 years. (if you can find the drag strip with a 1/4 mile of gold lanes )

Cool. Can someone do the math for scale speed?

To make the new nanodragster, Tour's team started with a previously built, off-the-shelf short axle and front wheel unit in their lab, which is sort of a nano-Monster Garage.
...uh, a nano shelf? Is that OEM or Aftermarket? How is the warranty on that thing?

So lets say it has an awesome factory laboratory warranty of 10 years, 100,000 miles um... 3.6 Feet.

Or would that be 1.453 billion years, 100,000 miles?

yeah they have a buckyball nano parts bin they raid for stuff like this. you'd think for a purpose built racer they'd do custom. but that's American car companies nano-labs for you.

i wonder if they have a little carbon nanotube/buckball stig to drive the thing?

Human hair - 25.4 micrometers = 0.0000254

Vehicle = 25.4 micrometers/50,000 (width) = 50.8x10^-11

Assume the length of the vehicle is 20 times it's width (20 atoms vs 1 in the picture) = 10.16x10^-9

I don't know what the proper length of a drag car is. I'm looking at pictures, and I'll throw out the arbitrary length of 1.5xnormal car length.

Normal cars are 5.1 meters long, 150% of that is 7.65 meters.

Your scale would be 7.65 meters / 10.16x10^-9 meters = 753,000,000 approximately (rounding up after the third leading integer).

So it goes at 0.014 millimeters an hour * 753,000,000 = 10,541 meters/hour

A mile has 1,609 meters. So this thing is traveling at 6.5 miles per hour.

Can anyone check my calcs :D?

your math is off.

The tiny hot rods can also do tricks. "Because the front wheels don't stick to the surface as strongly, they're more prone to lift up, so [the nanodragster] does seem to pop a wheelie at times," Tour told TopTenREVIEWS.
******* bad ***.

also, if you read the article jin, it says it travels at 9 nanomiles (.0005") per hour.

He was trying to convert it to scale, so if you grew the nano dragster to the size of a normal dragster, and the speed at the same rate, what speed would it be going.



I am not going to even try to confirm his math

Yep, was trying to convert it to scale. I made assumptions of size for:
1) The nano-dragster (50,000 times thinner than human hair)
2) The width of human hair (25.4 micrometers - http://hypertextbook.com/facts/1999/BrianLey.shtml, seems like a reasonable value)
3) The length of dragster (randomly guessed this one, if someone actually know the proper length and of one I would be glad to know)

Slap some stickers on it and cut your 1/4 mile times

dragsters come in different lengths. (thats what she said.)

i think 15-20 feet is about right.

Ok, that's fine. I counted for approximately 24 feet, we'll chock that extra 4 feet to super cool aero parts.
