Don't know if they are intending to run from the back of a truck.
What you said about the amount of throughput (water/steam/compressor) needed for it to function would not fit into the footprint of a truck.
Seems the truck is just to transport it the unit to site.
Instead of having to build it on a site.
If they can do it though it would create a new world...
Lets hope that they can and then we can stop arguing about global warming.
It would be worth it if only that could be achieved ...lol
