The fluid then squirts out through a rear-facing nozzle as the membrane contracts. To the team's surprise, the robot reached speeds of 10 body lengths per second with a peak acceleration of 14 body lengths per second squared. That's unprecedented in an underwater vehicle of this kind. What's more, the peak force experienced by the robot was 30 per cent greater than the thrust generated by the jet. The team think they know why and say the new technique could be used to design bigger subs capable of even more impressive octopus-like feats.
Reminded me of George Carlin...
"We're gonna go to Mars. And then of course we're gonna colonize deep space. With our microwave hot dogs and plastic vomit, fake dog shit and cinnamon dental floss, lemon-scented toilet paper and sneakers with lights in the heels. And all these other impressive things we've done down here. But let me ask you this: what are we gonna tell the intergalactic council of ministers the first time one of our teenage mothers throws their newborn baby into a dumpster? How are we gonna explain that to the space people? How are we gonna let them know that our ambassador was only late for the meeting because his breakfast was cold and he had to spend half an hour punching his wife around the kitchen? And what are they gonna think when they find out, its just a local custom, that over 80 million women in the Third world have had their clitorises forcibly removed in order to reduce their sexual pleasure so they won't cheat on their husbands? Can't you just sense how eager the rest of the universe is for us to show up?" - George Carlin, Complaints and Grievances
