  1. New battery chemistries adequate for most vehicles (not all) and stationary storage, the bulk of expected use cases this decade, DO NOT require Ni, cobalt or even manganese. Lithium Iron Phosphate batts are currently (pun) the longest lasting, safest and cheapest in mass production, the downside is some 30% lower energy density, still good enough for cars and improving.

  2. Just not very far.

  3. Not really, the discussion of environmental price is a BIG part of whether we "can" do it.

  4.  @D1ndo  Iron and lithium are everywhere and phosphate doesn't come from jungles or marine floors either. You can dream whatever you want, that doesn't make it viable nor necessary.

  5. Fatties are NOT about to sign up for a Mars mission....do you suppose there would be and endless supply of doughnuts, cheese burgers, fries and soda on such a trip?

  6.  @D1ndo  Only issue with Li is ramping up processing and yes mining, with possible exception of brine, has environmental price. So does fossil fuel extraction which batteries are replacing and unlike fossils, all the elements in batts will be endlessly recycled. Lithium is very common. Your proposed "solutions" are not likely available this decade if ever. Do you want to hold back a highly desirable revolution in transportation tech indefinitely for some nebulous future tech?? That's just ignorant or stupid. "Researched alternatives" typically go nowhere and otherwise take decades to reach economic viability. It took Li batts 1/3 century to be affordable at vehicle level. I don't give a damn about your thumb up or down.

  7. Lucas P You will be driving an electric car with in a decade or so and getting your deliveries via electric trucks and you'll never be so happy to be wrong. Unless of course you are the last loser in your town still fussing with fuel, endless maintenance, poor performance and high operating costs.

  8. I always seek the end users advice for designs for yet another reason--if they have real input that effects the crucial criteria such as dimensions, range of motion, etc., they will have a stake in making it work as some adaptation will be required by them too no matter how good the design is, if they feel left out of the process they may make a good design fail but if they are included they will TRY to make it WORK.

  9. Briseur De Lance YOU are one of those 'prophets' soon to be proven wrong. A decade or so from now you too will be using an EV even if you don't know it yet.

  10. Michael Cross It will be able to do all that and perform far better on the road then any diesel truck ever....with one possible shortcoming....the payload is yet to be announced. (a serious omission as noted in vid) It will do at least 60 mph at gross on a 6%, I would guess a lot better given their history of under promising on performance. You will be able to plug in, walk away for a 30 min break and return with an extra 300 miles of charge. Range will be a non issue. All you truckers will be envious of the speed of the Teslas and lack of maintenance headaches.

  11. And failing miserably, they disintegrated in what...few dozen miles?

  12. So they spend millions developing wheels but forgot that the landscape wasn't all soft sand so they came apart in a few dozen miles, BRILLIANT.

  13. Either clickbait or perpetuating the anti-science myth of anthropocentric climate emergency--either way THUMB DOWN.

  14. /b/ Tard There are some 6.5 MILLION jobs waiting for qualified applicants already and there has been a decade shortage of truckers. Complete nonsense to worry about jobs no one wants enough to take them anyway. Beyond that--it's called wealth creation, that requires productivity increases which ONLY happen when workers get MORE DONE as in, say, one operator controlling multiple trucks. Get a grip on reality.

  15. Even easier on an asteroid where you can use a kid's kite string but that doesn't get anything into EARTH orbit.

  16.  andy morris  Easy to say in hindsight but it was not at all clear the outcome until late in the war. Look what Japan already got away with in the rest of the Pacific region, China, Russia, Korea, on and on. Initially the US was losing and the entire West Coast was for the taking.

  17. Thanks for taking the time to offer us that Sir.

  18. "Gravity assist" is something of a misnomer--should be called say, momentum assist as that's where the extra energy is coming from, the orbital energy of the body.
