ok, so he can take comfort that he can blame a piece of metal for the accident rather than taking personal responsibility. if i had a car with a big honking A pillar, I would tilt my head a little to make sure there were no cars (or people) there before proceeding.
dude, lots of hate, but I don't see YOU offering solutions for distributing ice at burning man! maybe instead of trying to tear down others you should work to solve the world's problems one by one.
News flash: what's taught in college economics is known to not be correct, it's just part of a liberal arts education.
whaaaa? if i wanted to be wrong, I didn't have to go to college for that! srsly tho, do marginal costs equal marginal benefits? cuz I've structured my entire life around this single idea.
+1 insightful. People aren't running over pedestrians due to nefarious overly-wide A pillars; they're running over pedestrians because they're not paying attention and are talking on their phones and are more concerned with looking for a break in traffic so they can gun it through the intersection so they just run over people. it's ultimately because people are selfish. that's why when I'm a pedestrian I carry a "deterrent".
today I can drive my FC car from Tijuana to Oregon. soon it will be no problem to go to BC. and I can do so significantly faster than your "fast charger". One thing that you're forgetting about FC technology is while you have a hard on for your space ship car other nations are investing significantly in H2 and see it as having a strong future. Japan is all in on H2. the countries that are the most aggressive about GHG emissions are choosing H2 as their pathway to sustainability. you should ask your self, why are they doing so? it turns out they did not call you to find out your opinion before moving ahead with their plans.
+1 for providing a specific detailed answer to a reasonable question. The mist anybody else could do was self righteous snark. Typing lmgtfy! doesn't make for an insightful comment...
Hyundai has a new FC car out that I can lease today. The Toyota Mirai is coming soon. show me a worthwhile EV car that's not a $90k space ship.
They will never sell given that the cost of hydrogen will always be significantly higher than gasoline while being less green to boot
costs are on track to drop below gasoline on a per-mile basis. There are many H2 pathways that are very green and these are being scaled up rapidly. Also remember that FC cars are much more efficient than gasoline cars, so any metric has to be on a per-mile basis.
Making hydrogen from water is and always will be cost prohibitive due to the enormous amount of electricity required no matter the catalyst and fuel cell efficiency in a vehicle is maybe at best 60% efficient. Hell, it takes 20% of the energy contained in the hydrogen just to compress it to 5000PSI.
depends where you are. in the PNW electricity prices are 3.5 cents / kwh. if you're smart you can play all sorts of load-balancing and green credit games to get prices down really low. As a benchmarks, it is 60 kwh to make a kg of H2, including compression.
You can't transport hydrogen over regular pipelines and you can't economically transport it by truck like gasoline.
There are plenty of H2 pipelines. also plenty of tube trailer trucks. The people who move H2 all around the country think it's viable cuz they do it.
There's still also a lot of unknowns about fuel cells like how long the PEM membranes will actually last and how they'll hold up in various climates.
20 fuel cell buses ran in Vancouver for 3 years. 5 fuel cell buses run in palm springs. it's much more viable than batteries. also, FC's have the power needed to do some heavy-duty HVAC, while it destroys the range of a battery vehicle to turn the AC on.
Hell, they've already had one hydrogen fire at the hydrogen filling station in my county for buses, and that isn't used by the general public.
the AC Transit leak should have been NBD. all they have to do is open a valve and let the H2 bleed out. it was a bfd because the fire department wasn't trained on what to do and they had a shizz fit and treated it like a big hazard. What everybody learned from this is to make sure your first responders are properly trained.
Fuel cells are still costly to build and still require platinum and there's a lot of additional complexity as well.
prices are down 8x and there's plenty of room to keep improving. it's an area of continuing fundamental research.
HFCs will never come anywhere close to the cost of an EV. The true cost of the Toyota fuel cell car is likely over double what they're asking and the car they're selling is mediocre at best.
it's clear you know nothing about the cost or the performance of the mirai, so you should refrain from making uneducated statements.
Tesla is building out their network very rapidly and soon others will be following. Tesla's also using grid storage to even out the load to significantly reduce their peak demand.
nobody cares what tesla does. they're a boutique company selling the fantasy of owning a spaceship car. live in the real world not your fantasy world.
In a couple weeks Tesla will be starting their battery swapping. Once that goes in then the last advantage of hydrogen fuel cells is over.
loooool battery swapping is doa and will never happen. battery companies are only fake pursuing it as a canard to have a bullet point argument against other fuels.
Hydrogen filling stations will require that the hydrogen be made on-site since you can't effectively transport it.
so? then make it on site. there are many technologies to do so.
I don't need to read this to tell you why it didn't work. in my area we had sidecar service but didn't have too many cars. in theory, with flex pricing, boom, creates more incentive and we get the cars we need. instead, nobody wanted to drive over here regardless, so they all tripled their prices. a short ride went from $5 to $15. This made them way overpriced compared to Lyft and Uber.
I applaud Sidecar for trying something innovative. Flex pricing is a great idea in theory. if a driver has a sweet car, he can try to extract a couple bucks more. Similarly if the driver is a she and a hottie. if a driver wants to boost volume he can take a couple bucks less. but in practice it did not help increase service or competitiveness in my area. it's a shame cuz I really liked sidecar, they were the "funnest" of the three services.
it makes sense if youcan get a fully-functional fuel cell car vs. a hobbled limited-use battery car. show me one car outside of a $90k tesla that is not a hobbled 80 mile range putt putt car.
all these arguments are in circles. why would people on/. be against new technology? heck, people here root for space elevators. let's see what engineers can do and let the market decide.
and what about your dream of fast charger networks? those charge when you plug in, which is the point. you're going to drive to a fast charger then hang out for 5 hours then charge? no, you'll charge when you need it. get a clue.
research power to gas programs. when electricity demand is at a low, they actually take wind farms offline. this is missed green electrons. you use these green electrons to make H2 at electrolisys faciilities. then you can pump h2 into the ng pipeline for green ng, store it and run it through a PEM stack later for peak electricity needs, or use it for H2. it's cost effective with zero GHGs, which is why companies in germany, canada, and US are doing it right now.
also research the "duck curve" and peak demand charges. with an EV, you use electricity when you plug in to charge, and when you draw a lot of power (for example with a fast charger) your electricity prices can shoot up 20x. h2 you make it when you want and store it, so you don't have these peak charges nor are you impacting the grid.
while you're researching the duck curve, take a gander (ha!) at what drives electricity generation needs. it's not average load or total daily energy consumed. it's how much power is needed in the AM and PM peaks. you can make H2 during the lulls without impacting the grid or needing more generation capacity. EVs is not so, which is why when you scale out EVs to a large portion of the total vehicle fleet it becomes very scary.
in short, look at your comments above, then look at my responses here, and you'll see where your ignorance lies.
youre speaking from ignorance and youre boring me. evs will not work at scale. our aging infrastructure cant handle it. h2 can be made centrally and can be made during daily lulls when the renewables are idled due to low demand. h2 also avoids the issue of peak demand charges which can raise the price of electricity 100x.
im surprised theres so much hate for H2. its true that most hydrogen today is from NG. but you realize that if you run your EV in many parts of the east coast you're basically running on coal? that's much worse.
There are many H2 pathways that are from electrons, including green electron pathways. and there are other attractive ways of how hydrogen can be made from the grid without overwhelming it. you can make H2 when the grid load is low, using up renewable power that would otherwise not be used (eg wind power that is turned off because its not needed.
also, aside from the $90k tesla, all EVs have horrible performance and range. they're like driving an electric golf cart that goes 17 holes. their only real use case is as a second commuter car in a household. All H2 vehicles are full purpose cars, like gasoline cars.
In short, don't be hatin, slashdot. keep your mind open to new technology.
you're unbelievable! An employment clause! you know, you start a new job and you sign an agreement that says you'll get paid X, you'll get X weeks of vacation, X days of sick leave, and X weeks of paid cooldown when your employment is terminated. it's all completely legal, and there is benefit to both of the "afflicted parties".
I'm not sure I understand how this is supposed to solve anything.
ok, here's the deal. A senior govt person has gained experience that can be valuable for decades. He should be able to switch to a top private job where he can make use of that value. The person has lots of insider knowledge of how a company can win big deals. But this knowledge has a very short shelf life. it is like having an inside scoop on who will win the next horse race. A commonsense solution, take the head honcho out of the game for a bit, and then he rejoins when any insider-type knowledge is stale. But he can still apply his wisdom and experience for the coming years.
the trade off is that the govt would have to cover it. This is why it is a "forced vacation". but the cost would be much less than any graft that would be avoided. The duration of the cooldown period would be titrated depending on the seniority or level of influence.
i said it above. when a govt muckety muck signs a contract, include a clause with "forced paid vacation" after vacating your post. The duration of the vacation can vary depending on the mucketyness of the muck. as a result, nobody can jump from govt to industry to snap up a quick contract.

Then you more than double the mpg-equiv. you gotta look at per-mile metrics.
I suppose the EV lobby is any better?
Show me a worthwhile fuel cell car?
