Well Stevie, welcome to Efficiency 101
Efficiency = Useful energy output/input energy.
n = Pout/Pin
Where n = Efficiency ( no units, expressed as %)
Pout = the useful power output
Pin = the total power input
EFFICIENCY-Multiple steps
n(total) = n(1) X n(2) X n(3)dots X n
Where:
n(tot) = the total efficiency of the process
n(1) = the efficiency of the first step
n(2) = the efficiency of the second step
n(3) = the efficiency of the third step
n(n) = the efficiency of the nth (last)step
(n = eta)
In your case this would be on the order of;
n(1) the efficiency of the IC engine used to pick up your "free oil"
n(2) the efficiency of burning wood to heat the oil
n(3) the efficiency of the the engine burning the oil to run a generator
n(4) the efficiency of the generator being run by the engine
n(5) the efficiency of the battery charger
n(6) the efficiency of the battery
n(7) the efficiency of the inverter
The only person obfuscating is you.
TANSTAAFL!
This is education.
How can you expect anyone to take your advice seriously if you can't
account for your own energy use.
