            OK so a one year old, who still wouldn’t be walking outside by themselves.

            Edit: though i doubt they’re 30”. It’s an EV with solar panels. The size of the wheels will really matter for efficiency.

              It’s a prototype. They are made to look cool, not functional. Like typical camera wing mirrors which all prototypes seem to have, which no production car will ever have. Hell, this car doesn’t have any mirrors on it, or lights that pass regs for any country.

                Literally the genesis evs have camera wing mirrors lol. Camera mirrors are illegal in the United States so we’ll never have them here, but they are available in the rest of the world.

          I’m concerned you don’t understand what happens when a moving, 5,000 lb vehicle strikes a human of any age, laying down or standing up…

            That has nothing to do with the conversation. It’s clearly about seeing over the hood, which is a very common complaint about many American style SUVs and trucks. In this case your point is even more irrelevant, because low to the ground cars have higher survival rates since the average human goes over the vehicle rather than under it.

    Seeing comments nitpicking the body shape… it’s the exact body shape it needs to be to get rich investors to finance it and tech bros to buy it. Smart move.

    They can expand to sedans and SUVs later.

    Good thing being rich is a prerequisite for owning that thing, because a mild fender bender’s taking out the entire front end. Still, dead sexy.

    I’m a little thrown by “20% efficient” when paired with “allows 94% of solar energy to pass through.” Are they saying it captures 20% of 6%, i.e., 1.2% of the incident solar energy? Or are they saying 20% is captured and 94% passes through for a total energy recovery of 114%? (This latter is not physically possible, but that doesn’t mean it’s not what they’re saying.)

    Basically I would rather they listed the power output of the solar system in Watts.

      94% makes it to the solar capture, which is 20% efficient. So 20% of 94%. Bear in mind these are laboratory numbers, not real world. No one will ever get that in the real world.

        So using their numbers of 11 square meters at 1000w/sqm, and 18.2% efficiency would mean 2002w nominal assuming the entire car is illuminated. Multiply that by 4*365 to get the average annual production (2922kwh). Then multiply by 6km/kwh for the distance you could drive (17538km).

        Article says 17000km/yr

        So I think they’re overestimating by at least 40% since the whole car will never be completely in the sun.

          2kW is a LOT of production. That’d be enough to run most homes. If it’s able to produce that for five hours a day they’d hit that 17000km figure no problem.

          2kW × 5h = 10kWh 6km/kWh × 10kWh = 60km 60km/day × 365days = 21900km

    This paint is worth a lot. They should sell it. Apparently developed by them. Zero publications. How is it wired is the big question.

    I’d rather have actually efficient solar panels at home to charge a regular EV with; this is some solar frickin roadways level impractical nonsense. What if the paint goes opaque after a few years? What abput scratches and dings?

    Also can we make the wheels any bigger?
