So a new manufacturing process can make graphene in unlimited lengths and you start rolling the stuff up on a 1 cm diameter roller, 1 meter in length and you start rolling up this graphene as it comes off the machine making it. Now we take graphene as being a 1 dimensional object, but it is in fact about 3 angnstroms thick per layer.
So starting with that first layer, how long it is when it reaches 1 meter in diameter? Like a long roll of toilet paper but of course a lot thinner.

2.6 million km would wrap around the moon and back three times!
I calculated the first cm on the roll and it came to about 2600 miles but was unsure of how to do the whole thing. I tried to go to your site but get an error message 'server error' or some such, tried three times. I wanted to see what this guy's equation would show for that first cm.

Originally posted by forkedknight As for the first cm, that calculator gets ~262km
Yeah, saw that a bit late.
That guy's Plymouth went through 6 engines but still, he got 278,000 miles out of each one on average. The piece says he changed the oil once a week! That must have been expensive, 52 oil changes per year. Oil must have been cheap in Canada back then.
