Like the title says I'm new and I have a project in mind. I know this must have been discussed plenty of times and I have searched but have not seen a specific answer that meets my specs/needs. I have a gasoline powered electric generator at a small vacation home which has a 10HP engine OHV/OVC it produces 5,250 watts running 6,560 watts max (Black Max brand with Subaru engine). It has a 5 gallon tank and lasts about 8-10 hours at half load. I have it connected to the house in case of power outages via transfer switch and runs the whole house perfectly (dryer and stove run on propane).. Can I use hho along with the gasoline to make it run longer? If so how much hho (lpm) would I need? or What type of system should I build (how many cells etc). I have to get this question out of my head also even though is not the immediate goal: Could it ever run on hho alone? Thanks for your time reading my newbie message.
