For things that are "hmmm".
Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.
This is a good idea, though.
Piston engines are way, way, way more efficient (and cheaper to make) when optimized for one RPM and a static load (like a generator). They can be tiny if running at 100% throttle all the time; a few horsepower is enough. Excluding the transmission saves weight/cost, and a generator for a few horsepower isn’t that big.
Yeah, you get electrical loss, but everything else more than makes up for it.
México mágico
Still more efficient than a diesel car https://reneweconomy.com.au/tesla-ev-charged-with-diesel-generator-still-cleaner-than-conventional-car-61942/
above all, the biggest issue i see here is the mounting (or lack thereof) of the generator on the trailer.
please, secure your loads!!!
There is a huge missed opportunity of having modular battery packs that you can load into EVs.
You don’t need a huge battery for everyday, in fact it makes your drive less efficient.
What if there were standards and you could go to a gas station and rent some packs. Put them in the trunk (there would be slots and/or standard connectors), and then drive off.
Once road trip is over you return the packs (or you could buy instead of rent).
You can also just swap the packs in gas stations with fully charged equivalent, making long trips more flexible.
I think china did something like that with scooters.
I am totally ignorant and this is baseless, but wouldn't that charge the battery to go like 300 feet or something?
It would charge extremely slowly but you'd probably get a few kilometers of range out of it.
Checkmate, atheists!
Honestly, a car with a small urban autonomy battery with a system where the rest of the battery is on a trailer would be a pretty awesome system, but it would require some massive adoption and car manufacturers are just going with ridiculously large batteries and fast charging for two reasons: they can sell it for more, and fast charging wears out the battery faster and requires more proprietary maintenance as a result.
A lot of EV innovations that could have been have been denied entry suspiciously when they've reached the bureaucratic industrial standardization that most major car manufacturers just seem to be able to gloss over. The car industry doesn't want to see the profits from proprietary parts and maintenance go, and nothing beats a combustion engine for that. I still miss the Sono Sion, an EV with solar panels which would have been perfect for people who use their cars occasionally on the weekend and rental services. At least Aptera is still going strong.
Just charge the battery from a dynamo.
I ~~understand this is in Brazil (see the stores) and they have few charging places. ~~ Edit: not Brazil it’s Mexico. Not sure about EV infrastructure there.
Slugbug!
