Re: Efficiency is NOT MPG
Agreed, MPG is not a complete look at efficiency; carpooling is another common example to demonstrate that issue.
3 tons of cargo in a trailer behind a 1997 half-ton pickup is not safe or legal.
It is very difficult to harvest all that waste heat but we often have discussions about ideas for it. Some of the issues include ancillary effects on upstream systems, cost to implement the waste energy recovery system, ways to store and use the energy, and space required for the system.
