like most manufacturers he's talking waffle :

he makes a big deal that no gasoline is used, but what about the LPG that heats the water
and what is a 'a good vacuum' this could mean anything.
so on this 1 plug he is a running 2 pumps and hopefully 2 vacuums, (the water heater he uses requires no electric)
**************just looked at website**************
i can't see where he get the fact it will run off 1 power cord, all the arrangement he talks about have a miniumum of 2.
