    A story on Aptera is running on NPR (National Public Radio) as I write. When I can get my hands on a link to the story, I will post it here. One thing of interest I picked up was that they now have over 11,000 reservations.

    Not sure if anyone has mentioned this. I couldn’t find anything in the search but Lew Later did a small segment on Aptera back in Dec 2020 (https://www.youtube.com/watch?v=R0upghdeZAc).

    Anyone know if he’s gotten in touch with Aptera? Getting him to review the car when it’s available could be a big deal since his Unbox Therapy channel has over 18M subs and he mentions in the video he’s open to reviewing it.

    I forwarded your thread over to Aptera’s Media email… You never know?

    BTW under the Website’s Contact Us there is a list of emails to focus questions like this, as Aptera may not be reading the forum threads regularly

    A number of people have either sent me the article or sent the link as they know of my enthusiasm for Aptera. It is unusual for a paper to allocate so much space for an in-depth article. The author is an environmental reporter so she must have felt strongly about the potential contribution of the Aptera to repairing the environment and made a strong argument with her editor

    I want to drive a bottlenose dolphin, coefficient of drag of .01. Does anyone know if the hydrodynamic and aerodynamic drag coefficient’s are calculated the same way?

      The answer to your question is yes the same formula using different values for some variables.

      Both air and water are considered “Fluids” in the calculation. When calculating for air, the viscosity variable is 1. When calculating for water the viscosity variable is 1000 as water is 1000 times for viscus than air. A first year physics book, or of course Wikipedia will have the formula which is to complex to paste here. The drag coefficient is composed of frictional drag (viscous drag) and pressure drag (form drag).

    Wish they had taken a deeper dive into Aptera’s efficiency, rather than talking about the drawbacks of solar. I mean, really, this car is way ahead of the pack, even without solar cells.

    The article is skeptical about the car’s ability to dissipate heat from the A/C cooling system. Anyone following that closely?

    Did notice that in the articles. Another thing to remember is that cabin air & perhaps “engine bay” air is released by 2 vents by the license plate in back. Still unknown if they will use a heat pump or not. I hope so.

  • Robert Klasson

    Unless I’m mistaken, a heat pump is just running an AC in reverse. I don’t know how much you need to modify an AC to run both ways, but the gains in efficiency in colder climates should more than make up for it. If not for the first iteration, I would be somewhat disappointed if they didn’t pursue it sooner rather than later considering they are all about efficiency.

    Skepticism is unfortunate, but to be expected at this early stage in the development cycle. as the prototypes move forward, Aptera testing data is generated and published, and finally when government safety data is met and potentially exceeded, this skepticism will fade.

    Of course, it will turn to enthusiasm as people actually see and get to drive the vehicles. ????

    Robert, heat pumps for vehicles are relatively common. The issue with installing in Aptera is the weight. To this point, Aptera is working to find or perhaps have someone build(?) one appropriate to meet Aptera’s high standards for efficiency. I know they are continuing the sourcing activity with the goal in mind of having a suitable heap pump for Aptera

      Custom designed heat pump would make sense, but probably not easy. Lots of differences compared to, for example, my Model Y:

      — fewer human bodies to cool or warm (btw, seat heaters may be more efficient/effective than cabin heating)

      — smaller, tighter cabin with, probably, lower heat/cool through the body (composite vs metal)

      — lower motor cooling loads (if air cooling is not enough by itself)

      — smaller battery to cool/heat (in most cases)

      — May be relatively larger windscreen to defrost/defog.

      As an engineer, this would be a great challenge!

    The article as a whole was fairly positive. I wouldn’t be too bothered by concerns that they raised. The AC system is an open question. I have my own concerns about belly cooling efficiencies while sitting in stop and go traffic here in Atlanta in August. It’s going to be a challenge.

    I agree. Great video. I think I got a better feel for the car than I had thus far.

    Four things about the car that caught my attention – 1) Yes, a pretty deep scrape on the right side pant. 2) I’m wondering if that motor whine or hum can be mostly muted out (deadened) in the production. 3) When the car pulled into a parking spot with delineating white painted lines, the pants hung over the lines on both sides. 4). Both passengers seemed very surprised and a bit exhilarated by the acceleration of the FWD Sol. Fun to see. Hope they do a similar real life video of Luna (is that one going to be AWD?).

    Almost like taking a test drive! Very informal. A LOT of information on the Sol/Aptera. Glad to see control of the display is with buttons on the steering wheel. Counters complaints of having to reach over to touch the display to make a change while driving.

    Was wide in the parking spot. Cringe

    Borders on sacrilege that Chris would admit to driving a Tesla. At least it wasn’t an ICE. Probably should have been bleeped out

    I just wanted to say kudo’s to Kristen Dirksen and Aptera for putting together the most informative single video I’ve seen so far. This covers everything I’ve learned from watching a dozen other videos on Aptera. My only beef is that journalist are still being shown the original Alpha model, from 9 months ago. I would like to see them showing off the newer beta models with all the additional refinements.

    Overall great video. Anyone have any idea on what Mr. Anthony meant by “powdered” (what I heard) crystalline cell at 4:42 mark? I’ve worked with the same basic cells (SunPower) for the last 15-ish years that they’ve been available and I’ve never heard of them referred to as “powdered”. They are single (or mono) crystalline Silicon cells of the IBC type (Inter-digitated Back Contact).

      I don’t know whose product it is but saw the samples in their studio and it was very obvious on the dash in the Sol… as all the other cells looked like they were under the glossy clear resin outer skin

      Best way to describe… a matte dark finish… looks like a dusty surface on a wafer board

      Chris mentioned the advantage of the powder matrix over conventional flake like, in that it allows to conform to the curves of the Aptera body. Should is crack it could still function “ at some level”.



      They have these cells are replaceable by anyone, to original or future more efficient cells

      My picture is on the “Alpha Sol vehicle”. I imagine when they get up to the production version will be nicely set and fashioned easier to keep clean, etc. I assume these are the same that were under the clear resin of the body ¯\_(ツ)_/¯

        I’m as near certain the cells are SunPower/Maxeon as I can be. The metallization pattern Mr. Anthony shows later in the video is a dead giveaway.

        I’m familiar with the “matte dark finish” too. It’s a common look for anti-reflective “treated” single crystal silicon cells. I’m thinking that’s what triggered the phrase “powdered”. To repeat, however, it’s not unique to the cells Aptera appears to be using.

        Much of the matte dark finish goes away after encapsulation as you effectively described with the word “glossy”.

        Finally, if it’s not too sacrilegious to disagree, ANY appropriately thin silicon wafer (single or multi-crystalline) can conform to Aptera’s curves. In this case, however, the one advantage of the SunPower/Maxeon is the distribution of the rear metallization. Modest cracks would, indeed, minimally affect power output in, at least, the short term.

        Thanks for your input.

    Ok, so the video is cool…

    …However, nothing really new here. Another ‘test drive’ with a few more details on their design processes of the Beta. It’s October, I would have thought maybe they would be on to Gamma and crash testing.

    The comment related to the flexible solar cells as something “you can’t get off the shelf” is a little disingenuine. You can, check this: https://ebay.us/T9ajKP I did a little math and it would take aproximately 210 of these cells to get the 700 Watts of charging. It appears from the image below, that is about correct (I didn’t really get into counting them). Monocrystalyne cells are more efficient than Polycrystalyne, In the case of these Ebay cells, 22% +/- efficient.

    Still excited…still have tons of questions…still want to actually see one on the road.

    Looking good! Jay seemed to be having some trouble keeping it between the lines, and I hope the pants are made a little more solid in production. I’m sure they will…it’s just a bad optic to have them flopping around during the drive.

    • Ray Holan

      October 11, 2021 at 11:27 am

      Yes, Brad. I noticed the “dancing pants” a la M.C. Hammer in the video too. Of course, this is an Alpha vehicle and there’s a whole lot more development to be done so it didn’t trouble me at all. However, a prospective buyer comparing it to a Prius or Model 3 or a Chevy Bolt might get the hee-bee-geebies.

      I got a big chuckle out of Chris Anthony’s off-hand remark during the drive “You can’t pick your nose in an Aptera because everyone’s always going to be looking at you.” How’s that for a marketing slogan? LOL

      Nice !

      Towards the end of the video Jay asked to return with a production intend vehicle and Chris said Yes

      And yes something “kicked up off the road by the rear wheel. That could have been anything!

    This is the first I’ve seen about a frunk. Nice bonus storage. Good place for firstaid and emergency gear.

    Now I know it isn’t the production version but those wheel covers sure shake up a storm. Clearly not the final aerodynamics.

    PS: Did something fall off at 23:40? Looked like it came off the rear suspension but maybe they just lost a gopro
