Do you think there any short sellers covering still going or is the world just starting to realize the EV cost savings and yet Tesla is the only EV maker selling their vehicles at a profit?TSLA --- here we go again..........!
When we talk about ships we can return to the past, a lot of research on modern sails, automation etc so things happens.I just read an article that said enough batteries to move a 747 from NY to London would weigh some ridiculous amount. It then compared the power densities of hydrogen, jet fuel, batteries, etc... per pound.
Based on that, I don't think moving large objects like containers ships with batteries is going to be a viable option. The batteries would weigh more than the cargo and ship combined.
I don't foresee batteries as the only source of lower pollution energy. I know some aerospace companies are looking into hydrogen and electric engines (or a combination thereof).I just read an article that said enough batteries to move a 747 from NY to London would weigh some ridiculous amount.

Yeah, the article was on a hydrogen fuels airplane. It was comparing the power that could be squeezed from each pound of fuel source. I wish I could find it again. It was just yesterday. Grrrrrr.... (at least I remember what I had for dinner last night).I don't foresee batteries as the only source of lower pollution energy.

Fission and fusion power generation (fusion seems to be a fast coming technology reality).
Of course, wind and solar power, to a much lesser extent.
But until countries such as China and India (which account for some 25% of fossil fuel pollution) join in, there's little probability there'll be significant reduction in global warming
