>>1646135100 watts is about 500 calories burned, one bic mac, 4$ per hour via muscule work.
100 watt per hour is 0.1 kWh, at 14 cents electricity price and 80% efeciency this 1.12 cents per hour via battery pack. 400 times (!) cheaper. Think about carbon footprint you dofus.
But I see what DHL did there. Electricity is paid by DHL when calories are """"free"""" for capitalist, they are paid by worker. So let's turn worker into slave doing physical work like thousands years ago, so master can save 1 cent.
