No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Honestly it seems like a no-brainer to me to put a solar panel on the roof of electric cars to increase their action radius, so I figured there's probably one or more good reasons why they don't.

Also, I acknowledge that a quick google could answer the question, but with the current state of google I don't want to read AI bullshit. I want an actual answer, and I bet there will be some engineers eager to explain the issues.

Solar cells on a car have no real use. You would have to leave the car out in the sun for weeks to months to charge it up just once.

[–] Jarix@lemmy.world 2 points 5 months ago (2 children)

Seems worth offering as an option. If you can get 10-20 kms out of the solar panel in decent time it might be enough of an emergency precaution to give people who live outside of cities less reason to poopoo EVs

[–] Tja@programming.dev 2 points 5 months ago (1 children)

There's two problems with this:

Panels are not free. They cost money to install, weight to move around, and prevent you from a mega-sunroof that most EVs have.

Second, if you think one inconvenient charge per month will make people outside of cities and disparage (for whom EV already offer the most advantages) change their opinion, I think you will be disappointed. Most of them formed their opinion by "but I don't wanna!", not by any logical thinking.

This is the exact type of gimmick/bullshit they can utilize to convince people to get over irrational fears. Because people are often irrational when making decisions.

But its also tied directly into the fear of running out of juice in the middle of no where. It not only offers but actually gives people comfort and security. Even its really not meant to actually be used regularily or ever really.

I know one mechanic who has both a Model S and Leaf. He HATES that his model S slowly drains the battery when not used and his leaf does not. And he can explain the difference both why and how. If a company just used that fact to sell their car over any car that also loses charge sitting unused they will absolutely have an advantage for people. Imagine parking your car for weeks and it always being as charged as you left it or more instead of sometimes having to worry if you have a dead car waiting for you because you realized after the fact that you left it with a low charge

I absolutely do think it will change enough minds. I work in the industry from the repair side. But also with people who use their vehicle to pay their wage. I know this can work towards removing that part of the equation because there is a TON of people who dont want EVs to replace ICE and they stoke every dumb fear people have. Having the option, however poorly it performs has always been a net postive as long as it does perform the way its supposed to

Good sales people try to understand what is preventing people from making good choices. Bad ones just lie to you.

Additional costs are exactly what people expect to pay extra for ask in think that's really a moot point beyond getting the amount in the right ballpark.

I appreciate the long form reasoning, but I disagree. People I've met that don't like EVs, they don't like EVs first, look for a reason later. There is of course a tiny, minuscule minority that do more than 300 miles of driving a day and cannot spare 15 minutes to charge, but that is well under 0.1% of drivers.

[–] Jarix@lemmy.world 1 points 5 months ago* (last edited 5 months ago)

Never said it was people who drive high kms a day that has these concerns.

Seems to me we arent disagreeing on reasoning but about different situations. Such is the way of not speaking face to face though.

If it helps im not just making shit up, i deliver (ive moved up and am low level.operations now) autoparts to repair shops and have heard these complaints for over 10 years.

Its actually quite fascinating how often people drop the concern im trying to discuss once they start using an ev, or personally know someone who has one and they get encouraged by their persons lack of concern about losing a charge.

I think i wouldnt pay extra for the solar panel version if it was a significant extra cost but Maybr if it wasnt too much. (15k for full.self driving which doesnt even transfer to a new owner put the brakes on the failing enthudsiasm i had with tesla when model s was new)

[–] Treczoks@lemmy.world 1 points 5 months ago

More like 5-10km, and then only on a sunny day in the sun, which would make the car uninhabitable due to the heat.

Better put a few square meters on the roof and use those instead of the 2-3m² you can place on a car at suboptimal angles and with the requirement to park in the baking sun.
