    Crash Test Ratings

    I put "uses" in bold because I don't think a manufacturer puts the tested vehicles back into his inventory. I doubt Rivian has enough vehicles at this point that they can spare a few for destructive testing.

    Brake Lights

    If a Tesla vehicle decelerates at more than a threshold rate the brake lights come on. Teslas have accelerometers and that is the probable source of the signal but obviously regen current could be used alternatively or in combination with the accelerometer reading. I assume Rivian does something...

    Another Truck Concept - Nikola Badger

    Thanks for posting that. Should I find myself on Sardinia and in need of an orthodontist any time soon I'll know where to go. [Edit]This would be puzzling, I'm sure, did I not point out that it was in response to a post, which has since been removed, containing nothing but a link to the website...

    Another Truck Concept - Nikola Badger

    I was just thinking a bit more about this car and it occurred to me that it is really a PHEV with the second fuel being hydrogen rather than petrol. Perhas that has been observed already. We have to give them credit for being innovative but will the idea sell? The second best selling electric...

    ultrasound device improves lithium batteries

    Of course not! The R1T is 14% more than the Raven X! After writing that I feel I should explain that this is bucket list behaviour in an old fart and not something I recommend to younger people planning for their children's futures and their own retirements.

    Electricity ‘Out of Thin Air’

    The article doesn't say much but the implication is that the energy source is the water. The problem is that water comes from combining the hydrogen in a "fuel" with oxygen which releases energy. Water represents the energy depleted state. Energy is stored when hydrogen and oxygen are pulled...

    Electricity ‘Out of Thin Air’

    OK but what is the "genertor" or more particularly where does the "generator" get its energy from? What is its "prime mover?

    ultrasound device improves lithium batteries

    Remember computers, cell phones and digital cameras? These cars are high tech and as such this year's model is going to be substantially better than last year's. Eventually, as with all three of the devices named above things will level out somewhat but for now you are going to have to be...

    Electricity ‘Out of Thin Air’

    Where does the energy come from? How do you recharge it?

    Another Truck Concept - Nikola Badger

    I'm going to take electruck's suggestion and just start ignoring this gentleman. But I would like to address the broader question of how much science/engineering do you guys want here. I'm on a Cybertruck forum and frequently get comments that the explanations as to how things work are welcome...

    Yes, but that's because it is! Now I should have said burned fuel and I didn't assuming that anyone who understands how these things work would understand that. And, to be complete I should have mentioned that bypass air would make some contribution too. And I should, for completeness, have...

    Another Truck Concept - Nikola Badger

    ICE, battery and fuel cell are all dependent on chemical reaction and one of the most fascinating aspects of all this is that the chemical reaction is the same. That reaction is burning in which electrons are transferred from a fuel (reducing agent) to an oxidizing agent which in all three cases...

    Rivian customers share thoughts about preordering a vehicle

    Whether it's fair or not one cannot help but compare, contrast and compare actually, Rivian and Tesla since their approaches are so similar and yet so different. The point I was really trying to make is that Tesla seems to have no trouble with rolling out the CT with a couple of years backlog...

    We're talking about charging here.

    Yes. If you knew what the word meant you might have understood what I was trying to convey. But without training in one of the sciences one would not expect you to be familiar with words like synthesis and lysis as used by chemists. syn·thet·ic (sĭn-thĕt′ĭk) adj. 1. Relating to, involving, or...

    Another Truck Concept - Nikola Badger

    Again, your attempt to refocus on the semantics makes it clear you are not grasping the concept. More to the point, I don't know much about synthetic fuels so I went and did a wee search. The very first paper I came to mentioned hydrogen as being an example of a synthetic fuel. The first...

    Novice to EVs but a question?

    I gather you have no experience with BEVs so the following may be of interest to you (and to others here for whom their R1T or RIS will be their first). I don't have any experience with Rivian because at the moment I don't have one. So I'll tell you about Tesla and I think it is safe to assume...

    Another Truck Concept - Nikola Badger

    Sorry about that. I painted with a broad brush for brevity's sake and hoped you would be able to fill in the rest. The equation' 6CO2 + 12H2O + hv <---> C6H12O6 + 6O2 describes the carbon/energy cycle in very high level terms. Plants take up CO2 and water and produce nature's most basic fuel...

    Another Truck Concept - Nikola Badger

    We synthesize hydrogen from water by 2H2O + hv <-->2H2 + O2 just as we synthesize glucose from water + CO2 (6CO2 + 12H2O + hv <---> C6H12O6 + 6O2). To focus on the fact that hydrogen is an element, which of course it is, or that glucose is a hexose (which of course it is) only shows that you are...
