John B, and John G, and several others have made some good comments that supply a wealth of information about what makes a good system.
In my opinion,...."The weakness of any system"...ICE or Electric, is the lack of fully understanding the mechanics of what is being used.
At the base level of construction, ICE and Electric power units can in many cases be repaired and returned to minimum operation, using band-aids and shoe laces, in a manor of speaking.
An owner/operator of any power system should learn the basic reasons about what makes the unit(s) work, this will let someone know why a claim of 6.5hp for a motor operating from 120v @ 8.2amps just does not work.
I'm still trying to learn how to put my ideas into words and terms that others will accept and understand, my focus is now based on the simplicity of electric and compressed air only. I believe a break through design is at hand, so many design options have put my efforts at an extreme slow pace. The investor relationship that seemed possible has not materialized at this time, so my efforts are still limited to surplus and Harbor Freight (talk about band-aids and shoe strings) LOL.
I contend that batteries are needed, but not the big problem that their made out to be, lead acid will work just fine and pose very little problem if used in a proper cycle.
All I have time for, later
