Quote from: theaardvark on December 20, 2023, 04:20:28 PMZero emissions can also work with alternate fuels and combustion engines... I drove a Nat Gas conversion (dual fuel, could switch back and forth with Gasoline) for a number of years, filled it from the shop's gas line with a special compressor. Burns about as clean as possible. Alcohol is also an alternative. So there are emission busters that are not EV

Even more the CNG, although it rises, so doesn't make the slow leak CNG explosion issue that keeps those vehicles out of parking garages and tunnels.
Quote from: theaardvark on December 21, 2023, 03:29:27 PMEvery car manufacture is ramping up EV's. GM, Volvo, BMW, Ford, Nissan, all ICE companies now have substantial investment in EV's and thier production, and I don't doubt that if demand and resources were to become available, they could switch a huge portion of production to EV's. The fact Tesle started from an EV only platform did give them a leg up on the production tech, I don't think they have the corner on that production, or mass production for that matter.
Quote from: theaardvark on December 21, 2023, 03:29:27 PMThe big issue people seem to have with EV's is the charging infrastructure. Most see our grids as woefully inadequate to handle that much charging. But most charging takes place at night, when grid use is lowest. And I can see a day, sooner than later, when our houses have solar and wind generation capacity, and battery storage, that will more than compensate for EV usage, and actually end up putting power back into the grid in a substantial way. In the meantime, we are economizing on our grid usage, more efficient appliances, LED's and the like have left my home and business electrical bills lower almost every year, even with rising costs and increased use. And, with charging technology getting faster, I can see more charging superstations opening, powered by their own wind/solar, not drawing from the grid at all.
Quote from: blue_or_die on December 21, 2023, 07:32:52 PMI'm still waiting for evidence that compressed hydrogen is significantly dangerous in a mobility application. There are quite a few safety features that make it so that it has to be a perfect storm to make a cylinder explode. The nanosecond there's a leak (say, from a puncture from a collision, that gas is gone. Like you said, it does not accumulate and it's near instantly up in the stratosphere.What Tesla does have that others don't is vertical integration. They own their own battery supply which is the biggest factor. I agree that the legacy OEMs should be able to figure out mass production relatively easily but the capex and huge divergence of resources necessary is probably quite the annoyance for them.It's human nature to think about the handful of times you take a road trip or even just have a day with a ton of driving and it's easy to think that it's inconvenient to worry about range, worry about where to charge, and how long it will take to charge. Then again, plug-in hybrids basically solve that problem for just about everyone. They can and should do a better job of building those IMO.
Quote from: theaardvark on December 22, 2023, 06:15:44 PMThere are many critical points in fuelling for Hydrogen or CNG, which is where the concern remains. Once it is in the tank, its pretty safe (except for plumbing leaks, meaning they need regular inspections, using gas sniffers). My issue is large scale storage of the product makes for vulnerable targets for vandalism/terrorism, and for mishandling. Catastrophic release is catastrophic.
