Powerwall 2 is only 14kwh at 270lbs for $5500, or about $400 per kwh. You must mean the power pack 2 which cost 80k. Musk wants $100/kwh cost from the Gigafact

Powerwall 2 is only 14kwh at 270lbs for $5500, or about $400 per kwh. You must mean the power pack 2 which cost 80k.
Musk wants $100/kwh cost from the Gigafactory, but market is currently above $300.
Semi tractors only weigh 15-20k lbs your talking a battery that weighs as much as the tractor. 300 gallons of diesel is 2000 lbs and the engine and transmission is about 3000 lbs. it would be at least 10k heavier which reduce carrying capacity since gross is capped at 88,000 lbs total not to mention space.

- SigmundA 10y agoSemi doesn't have be electric to be autonomous, Frieghtliner is already showing diesel autonomous prototypes.
- gameshot911 10y agoTrue, and to those add the cost of externalities like mining on natural ecosystems and pollution on climate warming and our health.
- deegles 10y agoAre recharge breaks less time than human breaks?
- greglindahl 10y agoI suspect battery swaps are on the agenda.
- lscharen 10y agoYou are correct re the Powerwall and Powerpack confusion. I had gotten the information off of the Wikipedia article and accidentally combined information from the two tables. That definitely changes the cost/weight/power equations.
