Something I find incredibly weird about US company culture is how they talk about overtime like it's a good thing.

"Our employees worked weekends, days and nights to make this happen! We wouldn't have succeeded without people who are willing to give up their personal lives!"

I hope they not only succeed but get shares. Doing weekends or nights for a company you don't (partially) own feels like a con.

Find people who care about what they're working on and they'll go well beyond the extra mile. As an extra motivator, make it clear the company won't be around if they don't succeed. I'm sure these employees have shares, but tha only really matters if the company succeeds (extra motivation!). Unfortunately, there have been a ton of green/green-adjacent automotive "startups" that have struggled to gain a foothold. See also:

(I'm sure many others)

Here are a few other interesting green automotive startups that didn't make it:

  • Sono Motors' Sion: Compact EV with solar panels, power sharing, intended to be easily repairable and included a detail manual. They had prototypes but never went to production. Now the company does niche solar applications.
  • Workhorse: Series Hybrid (think Chevy Volt) Pickup truck with onboard power for tools etc (was announced around or even before Rivian). Was a very pragmatic idea IMO. Later sort-of resold to Lordstown. Now company does some other things, like drones.
  • Lordstown Motors' Endurance: EV Pickup Truck with hub motors. Made a few hundred, but they have been dragging it out long enough for Ford to make electric pickups. And the idea wasn't too original even when it was announced.

Fisker is nothing but a conman, always has been. His MO is literally to start a company, secure funding, make a personal fortune and then abandon the bankrupt shell and leave customers hanging.

I was thinking about the US lately. Can't remember why exactly maybe some friends popped up on my Facebook.

But I decided it actually wouldn't be that bad of a place to live. If it wasn't for the toxic work culture.

If they worked normal hours and had 20+ holidays it would be alright. Other shit annoy me and you would have to make sure you live in the nice areas but I could live there and enjoy it. But the work culture is an absolute no go. Wish they were like the Aussie. Show up do hard day of work fuck off for some beers. If the surfs good call in sick and end up seeing your boss in the line up. Work hard for a few months then decide fuck it and go to Bali for a weekend accidentally stay there for two months then decide you need to go back to work because travelling is too much effort walk into a job 1 week after landing home.

There's something that people really fail to grasp with solar, and that's the fact there is bugger all energy in the sun, and you need a huge surface area to get any meaningful energy.

A home solar array often takes up a significant chunk of the roof area, and the amount of surface area a car typically has means that even perfectly efficient solar panels wouldn't collect enough energy to significantly contribute to the vehicle's range.

There's a good reason why vehicle manufacturers don't bother adding them.

[–] [email protected] 24 points 3 weeks ago (18 children)

Yes, but with a light and efficient vehicle, along with enough area covered in solar, it should be able to get you about 15 miles of free travel when left out on a sunny day. It has a battery. It isn't just running on sunshine and lollipops.

[–] [email protected] 15 points 3 weeks ago (2 children)

Or 43 miles in Aptera's case

[–] [email protected] 8 points 3 weeks ago

I'll believe that when I see it.

[–] [email protected] 6 points 3 weeks ago (5 children)

I'm not believing they'll get even close to that in a production vehicle that's US street legal.

[–] [email protected] 6 points 3 weeks ago (4 children)

The body weighs around 360kg, with a 60kwh battery it supposedly weighs around 800kg (the smallest and lightest option is 25kwh), with a drag coefficient of 0.13.
In comparison to some of the most efficient cars - the Hyundai Ioniq 6 is around 1,860kg with a drag coefficient of 0.21. Tesla Model 3 is around 1760kg with a drag coefficient of 0.219.

It's going to be a whole lot more efficient than the average car just based on these numbers.

Now it depends on how much of the car's surface will be covered by the solar panel and what's the panel's efficiency.

Their tech isn't just the solar, they've optimized the car solely for efficiency. They claim their car can get 10 mi/kwh, so with 700W of solar panels they can get up to 40 miles of charge per day with just the solar. By contrast, the solar panels that are available on the new Prius get 4 miles of charge per day.

Now that their production-intent vehicles are just starting to be built up, I'm eagerly awaiting their actual test data that hopefully verifies their claims on efficiency, range, crash safety, etc. but we'll see 🤞 I really hope they succeed.

[–] [email protected] 5 points 3 weeks ago

Yes, the aerodynamics + solar panels is what makes this vehicle enticing, not just the solar panels alone.

[–] [email protected] 12 points 3 weeks ago (2 children)

Solar panels are also added weight, which reduces range. Any way you look at it, it makes more sense to have the solar panels at a base location you go back to.

I guess an RV, or a camp trailer, makes sense to have panels on it, but that's about it

[–] [email protected] 5 points 3 weeks ago (1 children)

There's also things like Sentinel mode on Teslas that use power.

My main gripe is people think a solar car will never need to be charged, or only on trips, and that's just not the case.

Solar panels are incredibly thin and light. There is no reason not to include them.

There is good amount of energy in the sunshine. The output of solar arrays struggle to make big power out of small surface areas because we haven't figured out how to get more than 20% of the power that hits the panel. If they do get 20% or more, it's been with very expensive and fragile panels.

Been following this company’s development for over a decade now. I really want them to succeed but I have major doubts.

It's good to see that Aptera is still a possibility!

It’s also a bit strange to see a production-intent build of a solar electric vehicle without any solar panels. Still, Aptera shared that technology will be implemented next alongside the SEV’s production-intent thermal management system and exterior surfaces.

This thing is pure vaporware. My new Leaf isn't.

[–] [email protected] 20 points 3 weeks ago (1 children)

Im not saying it isn't, but fitting custom curved prob special solar panels on a test vehicle does not sound cost efficient, especially when you can test the solar panels separately perfectly fine.

Cars are complex to construct properly even without drivetrains, plenty to test there.

[–] Cethin 9 points 3 weeks ago* (last edited 3 weeks ago) (5 children)

True, but my understanding is the amount of solar energy that hits an area the size of a car multiplies by the max possible solar energy conversion is still far below what's needed to power a car. Sure, you can continue to charge it while parked, which is cool. However, you could also put cheaper non-custom panels on a building and then plug your non-solar electric car into it to charge while parked, and the building panels will have significantly better solar exposure and be cheaper per panel.

If your goal is making something effective that reduces carbon output, an EV and solar on a building is much better. If you're creating junk to get VC funding, this is what it looks like. If this comes to market at all, it's not going to make any waves, except maybe for how impractical it is.

[–] [email protected] 8 points 3 weeks ago (2 children)

I could see a market for a small electric camper van (Like actual small van sized like the old VW vans) with a solar roof. For regular camping you would always have electric to charge your phone and if you wanted to tour around a bit you could probably stay at each location for 2/3 days and gain enough charge to make it to the next one (at least in summer)

You're taking for granted the fact that many people don't have the luxury of modifying their house/condo/apartment to install and maintain solar panels. Nor is it guaranteed that they have a garage/driveway to charge their car. With the Aptera, you wouldn't have to deal with the hassle or inability to install solar panels because you would be able to passively charge it anywhere it's sunny (i.e. while driving as well). So I disagree that this is just an objectively worse option than charging with rooftop solar, especially because of how competitively priced the Aptera will be compared to standard EVs.

Solar panels aren't worth it for a normal EV, but supposedly the Aptera is so small, lightweight, and aerodynamic (with that teardrop shape) that they actually add a significant amount of range.

[–] [email protected] 4 points 3 weeks ago (5 children)

Oh, I agree with you there (well, not in the tech itself, why not both, have panels on buildings and on some cars – plenty of people drive only a few thousands of kilometres/miles per year & still need a car).

I'm just saying that as engineer I would start testing them separately, in lab conditions first to get the basics & correct obvious initial faults, then separately outside.
As management I however would insist that engineer has to find a way to glue whatever solar panels they can find to the prototype if there is gonna be a press release.

I didn't read much what they are doing/going for tho, so can't say much about that.

No one is trying to take away your Leaf, though.

Let them push the envelope. Failing is a required pavestone on the road to almost every success story.

I'm excited to see them succeed. I love it when stuff is designed with function over form, and made practically. I'm a tall person, this is the only small electric vehicle I feel I could actually fit in

[–] [email protected] 8 points 3 weeks ago* (last edited 2 weeks ago)

A few things the cynics are missing.

  1. The engineers who are designing this car don't have the political power to push for better mass transit.
  2. Even in ideal circumstances, there will still be a need for personal transport vehicles and infrastructure. Small cars will still be needed.
  3. Aptera has 31 employees as of 2023. If they're working overtime, it's because they're letting the company do it. Maintaining good moral is way more important in small companies.

Please just do trains. They can even be solar powered - a lot easier than this.

[–] [email protected] 13 points 3 weeks ago (1 children)

Trains are easy and they're easily electrified already. So putting solar on the trains won't have any advantage.

Rails are the difficult part of railways. They never seem to put them between my house and my work. They've put something called a road in between instead.

[–] [email protected] 7 points 3 weeks ago (20 children)

I presume they meant to put in railway infrastructure.

Railways cost so much less than one highway, we could have a system basically from home to work.
(eg smol trams to a midway se station to high-speed trains)

Bummer. I want to give them my money, but they're not accepting new investments right now.

Lots of people here criticizing Aptera who clearly haven't researched the company or the tech.

A solar powered car that topped at 70mph would be ideal,

But goddamn, could you imagine just having one that topped at 30 MPh in a city? Infinite travel!

[–] [email protected] 6 points 3 weeks ago

If you can park on top of a parking garage, or in a spot on ground level where sunshine is not too much blocked by the surrounding buildings, you could surely commute on sunshine. Home parking barely matters for day shift workers in this scenario.

Good, now keep the momentum up, Aptera. You're so close to the reality.
