You are correct that the 737′s APU is gas powered, although it uses far less fuel than the main engines – and thus makes the WheelTug system much more fuel-efficient for taxiing than using primary engine power.

Some smaller turbine engines do use an all-electric APU for startup. I mistakenly believed that the 737 had this type of design, and I’ve updated the original article to correct this detail. Honest error – I certainly wasn’t trying to “make up facts”.

I'd love to see your news source for this APU that magically recharges is flight. Please do not make up facts. The 737 has a gas turbine APU. “Electric power comes from the plane’s existing auxiliary power unit, which in turn gets recharged from engine power during flight.”
