  • In 1900 there were more electric vehicles in the US than gas vehicles.

    Big oil won out back then, and again when it eliminated trolleys around the 1930’s, and it’s keeping its grip even now.

    US options under $35,000 pretty much suck in the US for EVs. They aren’t all that great under $50k.

    I wouldn’t have bought one yet regardless. They’re only just now putting batteries into production that I believe will last 20 years without needing replaced. I’m keeping my old hybrid until those batteries ramp up in production and make it to the US if they ever become affordable here.


  • I’m not anti solar, dude. I HAVE solar. Solar is a great thing. I just don’t believe it is the end all be all of power creation. I think fusion should be better. Smaller footprint. Safe, short term radioactive waste left, no battery storage needed, creates power 24 hours a day instead of 10 hours if it’s sunny. Honestly, it’s kind of a no brainer. Especially for urban areas\densely packed cities.

    Stay off trying to debate ev vs ice over this. When all the vehicles are ev, you’re going to need a LOT more solar panels and batteries to keep up. A whole lot more.

    As for the creation of nuclear waste from fusion; it doesn’t make radioactive waste like fission, it makes less and what it makes has a much, much, shorter half life.

    Plus, imagine re-blanketing the planet in all those solar panels in a 30 year loop as they age out. Solar is great for local stuff and your house. Fusion will be the ultimate energy source, so long as it can be perfected.


  • First, that’s funny, cause fusion is the energy of the sun.

    But secondly: Solar takes a LOT of real estate and materials up. Along with the batteries for storage. Then to completely be able to rely on solar, you’d have to have many more panels and battery storage than just enough for a couple days worth of power. Clouds and storms and snow and whatnot.

    It would take around 15,000 acres worth of solar panels to create the same amount of power as a fusion reactor plant on 50 acres.

    And the plant can do it 24\7







  • Part of the issue (I feel a large part ) is that the learning curve is too steep to get on Lemmy

    Now I’m not saying it’s hard at all; but it’s significantly higher than simply “go to a main page and create a user name and password”. Lemmy needs a sign up page that just random signs you up to an active instance (per the instances permission) and automatically subscribes you to the 50 most active instances to just get you started up.

    Making a getting started page that’s as idiot proof as any .com would probably go a long ways into upping our numbers here.



  • Such a dumb article. The ev problem in the cold is the range and charge speed. Not the weight or anything else. Lithium batteries take more damage charging and discharging in the cold. It also wastes a lot of battery to keep the battery and passenger compartment warm, and it will charge slower with a lower maximum capacity in the cold.

    Bottom line is that if you have a 500km range ev, you shouldn’t expect it to be able to go further than 300km in extremely cold weather, or have the same amount of torque\power. Even worse if it’s been left unplugged and outside. This won’t ever change with a wet cell lithium battery. Other ev batteries are slowly starting to crop up.



  • He left out an important data point with all of his math. One he doesn’t have any data on. He failed to account for down force created by the vehicle. He completely ignored it. Downforce completely changes breakaway speeds on the tires.

    As to why it gets slower times than a thousand hp car on the track, it’s simple. The car weighs MUCH more. Like 2,000 pounds more. That makes braking and turning and acceleration slower (but there’s plenty of power to overcome the acceleration) and like what he did touch on, the battery isn’t large enough to go “all out” on this track without running out of juice.

    If the byd car could use magic to make it weigh as little as the zr1 and not be battery capacity limited, it would wipe the floor with the zr1.

    So yes, 3,000hp and all wheel drive is a benefit. It just can’t overcome the weight difference through all the turns and deceleration on the track.
