Imagine if instead of very light legs, the centipede had 32 wheels with
heavy rubber tires. It would weigh much more and be much slower.
But if it only had 2 wheels it would be much faster... Name any animal
that can go 20mph on flat ground for 2 hrs, and do it more efficiently
than a human on a bike. .
Hasn't 6 legs won the evolutionary contest for the optimum number for
a bug? I think plenty of them would love to have wheels instead, but
that doesn't seem to be part of the biological possibility. I'd rather
have wings than wheels, though...
Yea, but build a deer powered bicycle and you'll have a deer going sixty
miles an hour for 4 hours.
I read somewhere that cockroaches if scaled up to human size, would be going
200 mph across a kitchen floor on their six legs, and while they can't go
that fast over rough terrain, they can handle most any terrain at high
speed. I think at cockroach scale wind resistance is minimized. The big
roaches would probably start to get slowed down by the air.
Wings are definitly a blast, but of course a lot of people have worked on
that. What they don't have is the manuverability and precision of birds. I'd
like to be able to land on branches and telephone poles. That sort of air
machine doesn't exist. Far as I know no plane flares it's tail feathers and
pulls it's tail down like most every bird does to land, nor do planes change
their wing angle radically on landing. Human machines make small adjustments
and do it very slowly which leaves our landings and takeoffs to huge
runways. Helicopters are so slow compared to pigeons.
