    We’re still pursuing it. Batteries do not work for basically anything other than average passenger vehicles in the city or near cities. They do not work in construction, they do not work for heavy equipment, long haulers or even large sea vessels…they do not work for shit in aircraft that carry anything other than itself or tiny payloads…and they really are pointless for any sort of space propulsion. A mixed energy planet is what is needed, not this “batteries are the end all be all” thought so many of you have.

        Weight is always an issue, who told you it isn’t? And sounds like you know something these engineers don’t.

          Some locomotives alone weigh hundreds of tonnes, while weight is an issue, it’s less of an issue than most applications.

            Yep, but you’re suggesting that a train which with a diesel motor that weighs that much, wouldn’t be an issue with batteries. If you are going electric, skip the batteries and go over head tram lines and be done with it.

                And you think a train full of batteries is going to be able to do what a fuel locomotive can?

                    Range. Plain and simple. It takes 10-15mins to refuel a train, you’re not recharging a massive bank of batteries in 10-15 mins. On top of that, colder areas mean even less range.

      Most of the items you mention are being overtaken by better batteries. Long haul trucking batteries will likely be at cost parity with diesel trucks this year. Big cargo ships should probably go to SMRs. Airplanes no longer look as out of reach as they once appeared.

      Space flight is such a specialized use case. Of course hydrogen will be the predominant fuel there. More because there’s limited options than anything else.

        None of what you have is being done on a large scale because it doesn’t scale. Batteries are good for basically close cities where range isn’t an issue and super chargers are easily accessible. Everywhere else they do not hold up. You will never see a battery operated crane or some farm equipment, it’s just not possible with our current tech. If batteries magically decrease in weight, cost way less, are rechargeable in 5mins from basically and 110/120 outlet then sure, but for everything that isn’t some nice paved road and a semi short trip, it’s not happening.

            Yes…those 4 hours must be amazing…then it needs to be plugged in…to a what? O right a generator that runs on diesel. You clearly do not understand how construction or anything heavy equipment works do you?

                  I’ve never been on a construction site that didn’t have mains power, and I’ve been on quite a few.

                    Almost everyone of them is done with a generator. Or they’re done with the crane and inspections for power have been completed and the crane is no longer needed.

              Edit: oh, and these can go a full 8 hours, and have interchangeable packs if you want to go longer. This is an odd definition of “never” that you have.

                So let me get this straight, you think a crane runs for 8 hours and then the job is done? And interchangeable packs is hilarious. I think you’re completely missing the point, even if it is battery powered, they still will most likely require a generator running on diesel to operate after the 4/8 hours of run time.

                    O they do, but they’re running a diesel generator…which defeats the purpose of going green.

                  So let me get this straight: you have no idea how battery technology advances, how it works, what already exists, or how to construct a valid argument?

                    Cool. Replace battery with the word hydrogen… that’s been your logic this entire time.

                    And no I just exist in a world that isn’t in the city nor in a place where the most I travel is to whole foods…I exist in the world of heavy equipment and have an understanding of how all of it works. You clearly do not.

            Lol, yes all farms have power to the fields…lol the fuck are you smoking. I own a farm, some days I’m running my tractor 10-12 hours straight…no one I know in my community who does any crops or hay would buy that.

              It really depends on what you’re farming, but vineyards etc tend to be quite a small area with a yard that all the machinery returns to at the end of the day, I doubt it would be much of a hassle to come back to the yard and charge at lunchtime.

        Long haul trucking batteries will likely be at cost parity with diesel trucks this year.

        We have 2 electric Volvo FHs with everything else speced exactly like my diesel powered Volvo FH 500 turbo compound (gearbox, final drive, tyres, cab/cab equipment). With my 1265 litre tanks, I go about 4000 kilometres - load dependant - against their max 300 kilometre range - also load dependant. It takes me 15 minutes at a fast pump to fill the tanks. It takes the EVs 30 minutes to get to 80% on a fast-charger. They cost more than double my ICE to purchase. The price has a long way to fall, ignoring the range completely. Battery powered trucks are only good for the ‘last mile’ deliveries, everything else needs to be hydrogen powered.
