Probably worth considering the efficiency of converting that stored energy to useful work. Average ICE efficiency is ~20% yielding effective storage of ~2600 Wh

Probably worth considering the efficiency of converting that stored energy to useful work. Average ICE efficiency is ~20% yielding effective storage of ~2600 Wh/kg. Roughly an "order of magnitude" more density. EDIT: Hadn't refreshed the page since lunch. Many have made this point already. Apologies haha
