According to Dyen, a policeman was clubbing a student in the Yard during the bust. "A kid in a wheel chair, probably a friend of the guy being beaten, rolled up and pushed against the cop and told him to cut it out. The cop turned around and slammed the kid so hard he just sailed out of his wheel chair onto the ground...
...there in Harvard Yard on that raw April morning in 1969. I was standing in front of the east doors of University Hall and I witnessed the "wheel chair episode" from beginning to end. The facts are quite different from Dyen's malicious fable...
Near the end of the bust when the police were taking students out of the building, a student in a wheel chair did appear coming along the path from Memorial Church. No one was near him; he was propelling his chair by himself in the direction of University Hall. I remember thinking he looked extremely agitated. His head was swaying from side to side and he was shouting loudly. Still with no person close to him, he swerved up to the space between University Hall and Thayer. I saw him pause and look around to see if anyone was watching...
Among the most ancient of mechanical devices, the flywheel works on a simple principle: a rapidly spinning weighted wheel serves as a highly useful reservoir of energy. It has been put to work in a wide variety of ways. As a potter's wheel, it smooths out motion between movements of the foot pedal. On the crankshaft of an auto engine, it prevents uneven rotation that would result from piston strokes. But it is only recently that engineers looking for less polluting means of transportation have begun to give serious thought to tapping the whirling flywheel's energy...
...flywheel can be kept rotating longer if its weight or its initial rate of spin-or both-is increased. Trouble is, top speed is limited by the strength of the flywheel's material. Had the Electrogyro's wheel been spun much faster centrifugal force would have ripped it apart. In the vehicles being equipped by Lockheed for San Francisco, the flywheels will be revved up to 12,000 r.p.m.-fast enough to drive a fully loaded trolleybus (80 passengers) for six miles. To keep such fast-moving machinery in one piece, say Lockheed engineers, they will...
