[KYHAM] "gas" vs. diesel gen-sets (was BPL, Ham radio and the EOC)

[Bill Fuqua]

how about gas vs diesel vs microturbine
They are expensive and consume more fuel but some new turbine technology 
has made
the newer ones attractive. Mostly practically zero maintenance. The air 
foil bearing technology has done
away with then need of lubricants ( no oil) and they can run off multiple 
fuels. Some units will run on either
kerosine or natural gas or propane. The generator is directly driven with 
no gear box and inverter generates
the  AC Power. They have been made more efficient by recycling some of the 
waste heat.
     Just change air filters once and a while.
Most are made for stationary applications.  The EV1 hybrid prototype car 
used a 30 kW Williams air foil bearing
turbine to recharge its batteries and extend its range.
