 So, how long does it take to charge it up, a year How long will it operate for, a full 24hrs And what environmental damage is done to make the batteries What is the life exepctancy of the batteries Can the batteries be recycled What is the carbon footprint of each of these machines And what is the cost All the above questions are to be considered and compared against a regular fossil fuelled machine.
Putting aside the "green army brigade" arguments for the machine. The logistics, the charging, the overall ownership costs, environmental costs and relying on the infrastructure just to charge it up make this machine a waste of time and effort.
Fossil fuel emmissions have never been cleaner and for me the Greta gang need to accept that the world is not doomed by man burning diesel in diggers and vehicles but more at risk from super volcano extinction events, asteroid extinction events and nuclear war extinction events.
