tl;dr: The claimed range is 50% higher than the worst assumptions for battery production, and 500% higher than the best assumptions. But it's not an apples to apples comparison. Carbon emissions from battery production The range of values estimated for emissions from battery production varies widely in the literature: In an answer on Sustainability.SE I ...

In addition to all the other great answers there is one very important fact that's always ignored in these comparisons (Google translation, lightly corrected by me): The total emissions of petrol and diesel are sugarcoated in this example. For oil extraction, refinery and transport on tankers, in pipelines and trucks 44 kWh of energy was used for ...

If I'd spent 30 seconds looking instead of 2 minutes posting here I'd have found the answer on Snopes. Its an old legend dating back to at least 1978. Origins: This legend surfaced in print in 1978, but an anecdotal sighting places it even earlier than that, in 1971. Though its exact beginnings can’t be pinpointed, according to Brunvand: The June ...

While I don't know if this particular company is doing something useful or not, I can talk about what an aluminum battery could be used for in electric cars. In general, electric cars use lithium ion batteries. The problem is that in order to get a decent range, you need a lot of batteries. From an engineering perspective, these batteries are heavy, which ...

IVL, the source of the 150 to 200 kilograms of CO2 figure, recently published a new study that ended up with a much lower estimate: 61-106kg per kWh of battery capacity, depending on the energy sources and efficiencies of different manufacturing plants. "[This] puts it much more in line with other studies."1 Reasons for the difference: The new study ...

This is not intended as a complete answer, but we do know the inventor does exist and has made these claims. But the articles are misleading, especially the Daily Mail one using language like this: Imagine the satisfaction of driving your environmentally friendly electric car for 1,500 miles without having to stop to recharge the battery – a distance ...

There's dispute in the numbers. Tesla makes the claim, of course, that their vehicles equipped with Autopilot have lower accident rates than their vehicles without. In 2017, the National Highway Traffic Safety Administration said that Tesla collisions dropped almost 40% after Autosteer was installed, but that number was disputed in 2019 when a report ...

It would help to see the text of the interview, or at least a clear statement of the claim. Your phrasing "He claims that would have caused hundreds thousands of deaths (not clear, US or worldwide)." is ambiguous as to what "it" refers to, and you phrased it as a counterfactual (something that didn't happen), but if "it" refers to "The government taking ten ...

Is this video legitimate? This particular video appears to be a hoax: The video above is a joke that some people seem to not be getting. RIffing off the "you can put Doom on anything" meme, from graphing calculators to printers, YouTube user vexal put together this video showing the three simple steps to getting the classic first-person shooter ...

Edmunds.com conducted a test using a 2007 Toyota Tundra. Edmunds They found that at 65MPH, fuel mileage was 19.1MPG with the a/c on, 20.9MPG with the windows down and air off. Based on personal experience, I'd say that's pretty close to what you could expect across the board. Different makes/models will differ aerodynamically, but a 1-2MPG increase ...

No. There's the calculator from Finnish climate change panel at https://www.ilmastopaneeli.fi/autokalkulaattori/ Unfortunately, the calculator is in Finnish, but the tool has quite good defaults. The vehicle 1 is a gasoline powered car (Bensiini), and the second vehicle is a pure electric vehicle (Sähkö) with a battery size of 42.1 kWh. The life cycle ...

I've personally been recording tow operator deaths since the first one I discovered occurred in October 6, 1934. Since then, more than 945 tow operators worldwide have been killed in line-of-duty incidents regarding all kinds of reasons; vehicle accidents, crashed, overturned, ejected, struck as pedestrian workers, shootings, stabbings, choked to death, ...
