price/performance for ic engines?
a friend of mine sent me the following question. Anyone got any ideas?
Silicon chips have followed an exponential improvement – what’s it been for internal combustion engines? Of course, there are many factors that have to be traded off (fuel efficiency, emissions, power output) and so there isn’t a simple way to measure progress. But just take power to weight ratio. I assume it’s improved a lot. Is it still growing strong, or is it asymptotically approaching some theoretical limit?
