I presume you're using a heat exchanger to cool the exhaust and heat the discharging pellets. How big a temperature differential are you getting from the exchanger? How much extra energy do you need to put in for cooling? At switchover, how do you cool the pellets that you've just finished heating? Is the heating-compression cycle a lot faster than the collection cycle?
Given the overhead and hassle of putting small units on a huge number of trucks, how does this compare to just putting a small number of larger units on power plants or furnaces?
--How important is the CO2 concentration in the exhaust? Is this something that could be done just from atmospheric CO2, not on a concentrated source?--[Edit: Already addressed below.]
