quote: Unless those change, biodiesel is going to win in the end. Its only impediment is the algae => diesel step (or plant => diesel step). Right now that's prohibitively expensive, or scales poorly so you can't crank out massive quantities of diesel. That's what's given EVs some breathing room. But rest assured, if (and that's a highly probable 'if') we figure out a way to make that step cheap and scalable, it's game over for EVs.
quote: This isn't like drilling for oil where you get a nearly pure enough commodity directly out of the ground, or a typical industrial process using pure raw materials to build a more complex product.
quote: You really think that's a "highly probable 'if'"?Algal growth isn't just a matter of CO2, water, and sunlight. You need other nutrients, or else they'd have covered the earth already.
quote: I'm not a solar fan either, but the theoretical efficiency of photosynthesis is 11%, with 3-6% being more realistic:
quote: I seriously doubt algae will ever yield energy cheaper than solar panels. Even a woeful 10 year avg life on a Chinese $1/W solar panel will give you 80 MJ of electrical energy per dollar, and motors are >2x the efficiency of an ICE, so for $1 you can drive as far as 1.5 gal algal biodiesel.
quote: Anyway, the real future competition for algal biofuels is not battery+solar, but rather battery+nuclear.
quote: EVs are still going to eventually win out
quote: The more dense the battery capacity, the longer it takes to charge.
quote: Charging isn't a technological hurdle, it's a procedural one.
quote: Ummm yeah. Can we say unsustainable as hell? It's not even feasible.
quote: Some people just don't think things through.
quote: LOL that's rich. You guys are writing off battery swapping by coming up with the most moronic solutions possible. If a battery charges in 30 minutes, a 2-minute swap needs only 15 batteries per station to be running continuously at 100% capacity (30 cars per hour). Since the packs can be less than 6" thick, they'll fit in a space under the pump and car.
quote: Tesla is only finding 6% of Model S mileage is charged at superchargers.
quote: I just pointed out how pathetic you guys are with numbers.
quote: I very clearly said "battery swapping won't get anywhere".
quote: So in your mind we live in the times of the Jetsons. You'll pull into a station, centered perfectly over a door in the ground of course. The door will slide open and a mechanical robot arm comes up, quickly and perfectly removing your cars battery pack. Then another robot arm comes up from this completely automated pit, and slaps a new battery into your car and you're good to go.Just..lmao!!!
quote: This is a biofuel you dumb shit.
quote: But to say EVs will die because of alternative fuels is just wishful thinking on your part. I think Musk is a smarmy, self-righteous tool too, but EVs will not go away even if Tesla flops.
