Don't bother its above intellectual capacity of some folks he simply uses his car which he drives on fuel
Let me translate so its easier for your to understand.
When he drives his battery is recharged (for free , again some people can't conceptualize it but its fine)
When he comes homes , he (paid for fuel once for his car) but he has 4-5 hours of free electricity ... no need to pay electricity bill
His Monthly Bill
Car petrol (YES)
ELECTRIC bill (NO) he uses his battery in car to run stuff
The idea is 100% logical , infact NASA uses these same ideas in planning for basis on moon nd mars in future , conservation of energy
This is a very basic engineering principle .. physics
Convertying Mechanical Energy into Electrical Energy
You can get on excercise bike , and convert that motion into Èlectricity
So what he is doing is , using his car to
turn the wheels , which charge up his battery very simple idea
Draw back is he has to pay for petrol but he already pays for it because he has to go to work and come home , but he gets
FREE ELECTRICITY because he is smart .. and uses his brain
SIDE NOTE:
The battery in your car when you drive , it gets charged as you drive ... he simply is charging a second or third batty hidden in trunk .....
This second battery he removes form his trunk in car end of day and connects to his home
wires , which power his fan + lights + small radio etc
Instead of paying Saud Clan more money like our Ullo Government does paying money for no reason
Can you imagine if all cars in Pakistan had this battery system how every one will get a 30-40% of their Electricity free instead of paying CORPORATIONS large bills ?
