Comment Re:Cam shafts work without the battery (Score 5, Insightful) 383

But the failure of a mistimed valve is way more catastrophic than that of a misfiring injector or spark plug. Even if an electrically actuated valve system was to be used in production I'd expect it either to be supported by a backup mechanical system or to be designed never to interfere with the volume occupied by a piston. In the first case the electronic valve would be an additional cost only justified on high performance engines, in the second case it would affect the performance negatively. Perhaps this could work with sleeve valve engines?

Comment Re:that still doesn't help you catch the buggers (Score 2) 275

Something that can barely puncture through the skin of a missile takes a whole 747 to carry. I think something more reliable would be a detection system that pinpoints the origin coordinates and automatically signals the laser's origin to someone on the ground. With current GPS and mapping systems should be possible to get sub meter accuracy. A quick response drone could also be dispatched to take pictures to document the nature of the offender, for when he's then brought to court.

I was about to suggest exactly the same. You can do any sort of stuff on the Beetle, from fitting a Porsche engine in it, to replacing the entire front half with that of a chopper bike, to cutting the engine in half to use it on a microlight. And it will just run forever.

Comment How can you still keep a straight face? (Score 1) 187

Time and time again your forecasts about legal disputes have been falsified in court. How can you still offer your allegedly unbiased opinion as an expert on patent law and still keep a straight face? Aren't you perhaps confusing what you (or your sponsors) wish the body of the law is with what it actually is?
