Rob I normally do not like to comment on references to wars, but you touched a sore spot here. For a war to be won; first tehr must be a clear cut objective and then there must be either an adversary willing to admt defeat or the total anihilation one side. I do not care if it is sticks against bombs, if the sticks are willing to wait long enough, centuries even, eventually the bombs will tire of the effort, declare victory and go away.
Guerilla tactics cannot win a war, it can merely prolong it until the other side tires of the exercise. Robert E. Lee saw that when he commanded the south to drop their weapons and go home, rather than continue to fight on a guerilla basis.
The anihilation tactic was evident in WW II. The Japanese had vowed to fight to "the last man" and the US demonstrated not only the ability, but perhaps even the willingness to kill the last man when Truman ordered the bombings of Hiroshima and Nagasaki. Only then did the Japanese government call an end to hostilities.
The reason for the ineveitable outcomes in Vietnam, Iraq and Afghanistan is because there are factions in each that are/were willing to wait as long as necessary while random bombings, suicide attacks and various similar tactics break down the will of the outsider's populace to support the activity.
My goodness, Ann. That's an impressive development. So potentially, a robotic earthworm could be created that would mimic two major aspects of an earthworm: the ability to burrow underground and the ability to process underground material into rich earth.
I'm not so sure that making topsoil from trash is a joke. A couple of different microbes have been discovered that can or have the promise to, digest plastic and make it compostable. Theoretically, armed with some kind of delivery mechanism, robotic earthworms could then make that idea a reality.
I understand, Ann. I'm just surprised the concept is getting tossed around. That proposed idea is an interesting application for robotic earthworms. I would certainly guess the notion of it making topsoil from trash is a joke. But who knows, it might show up sometime as a trash mining apparatus.
OK, Rob, you got me curious. Wouldn't you know, there's a combination of predictions from the World Future Society about robotic earthworms for landfills to help with biodegradability and extracting metals and plastics (Forecast #4--the whole list is interesting):
I agree about the serendipity of Lawrence's death, a freak accident after everything he had lived through. What a tragedy. I think Korda's book is an exceptionally good read and covers a lot of history in the process. Since Lawrence was busy making that history, that's not hard to do in a biography of him.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
