A long and boring video of first GEET and standard lawn mower test. The standard system won by far. But I don't think that this was a fair test as I could not bring both engine to rev at the same RPM. And I also could not see the actual gasoline volume in the standard tank. I forgot to open the gas valve as I warm up the motor (the motor dies prematurely and I thought the tank was already empty). There was more gasoline there than on the GEET one. I think I have to make another test using a transparent bottle as a gas tank for the standard lawn mower.
