Overview:

Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

Fake news said that perpetuum mobile is not possible. Take that, naysayers!

So does it go forward or backwards or just creates a black hole

I’ve done this… I had 700w of solar panels on my car, that fed a 2kwhr portable battery, that fed the car charger. It’s only bought to get 15-20 mile/day, but it’s something.

I used it when I was cross-country traveling and was off-grid camping. It was mainly way I could get back to civilization after a week out in the middle of nowhere. Also made enough power to run my air fryer and computer/starlink setup.

It seems like electric cars are commonly parked outside in the hot sun all day, and so should have solar panels - it wouldn't be all the power you need, but for the average driver it would be about a third of their total driving. Plus that if you do run out the solution is just wait a couple hours it a powerful (though in reality not useful) message. Solar panels could easially be shaped to the roof of the car and thus not affect aerodynamics (in quantities of the auto manufactures this is an option).

I want a retractable panel that covers my wind shield so my car doesn't get so hot while I'm inside - this is a feature I'd pay for even if it isn't cost effective.

We should be putting solar panels over parking spaces anyway, rather than over places where plants could grow. Combine that with electric vehicles that could plug into that infrastructure.

Agrivoltaics can be a net benefit for plant productivity depending on the region and field type. Pasture for sheep does fairly well, for instance, as grasses do better with some shade in a lot of cases. It reduces water requirements and simulates a lightly wooded or scrub area.

Devil, details, etc.

Putting solar panels over parking spaces is a terrible idea - it's far more expensive, makes it far more liable to be smashed by some idiot, and requires high-embodied-emissions steel/concrete to car-proof your solar panels as a result (technically just car-resistant).

Meanwhile, car parks are a stupid symptom of car-centric design and should be phased out. Putting solar panels on a car park isn't smart use of space, it's just putting lipstick on a pig.

I thought this was someone using the V2L function and running a gaming rig inside.

[–] acockworkorange@mander.xyz 1 points 2 weeks ago (1 children)

Outta here with your FACTS and LOGIC! I'm glad mine has internal 120V outlets.

[–] ThePantser@sh.itjust.works 1 points 2 weeks ago

Usually the bones inside are limited to not many amps. The V2L would allow for a much higher draw.

lol, who knows

you can just put solar panels at the roof

They're pulling juice from a portable power station that's being kept inside the car. The thing is that they'd better have a strong juice-generating build or else the weight of the battery itself quickly nullifies how much benefit it provides.

[–] Mihies@programming.dev 1 points 2 weeks ago

Actually I think they had an adapter for 220V outlet in the car or something similar since there was another cable out of the front door that looked like you usual home 220V/10A cable.
