Car dealers fear Tesla. In states across the country, powerful car dealer associations have lobbied to ensure the electric car maker and its direct-sales model are kept out. This movement claimed another victory this week when New Jersey banned Tesla stores in the state.
On the surface, the fear is hard to fathom. In New Jersey, for instance, sales of Tesla’s $70,000 Model S reportedly number in the hundreds. But if you dig a little deeper, it becomes obvious why dealers are worried. They don’t just fear Tesla’s cars. They fear Tesla’s plan to create a world where you never have to bring your car into the shop again.
The ability to repair a car via software is especially important when the vehicle itself consists of so much new technology that traditional mechanics don’t know how to fix. The flip side is that without an internal combustion engine, there’s not as much to fix. I’ve written before that a Tesla without its outer shell looks like a cell phone on wheels. It’s basically just a big battery. That means no spark plugs, no air filters, no fuel pumps, no timing belts. In short, Teslas don’t have any of the parts that force you to take your car in for “regularly scheduled maintenance” — services that can cost dearly at the dealer. But it’s hard to charge for an oil change when there’s no oil to be changed.
At Tesla’s most recent annual meeting, one shareholder asked founder and CEO Elon Musk about whether challenges to the company from traditional auto dealers hurt the company’s business outlook. Musk argued that consumer desire for a better way of buying and owning cars would win out. He said the traditional franchise model that dominates auto-selling in the U.S. wouldn’t work for Tesla for several reasons, including its reliance on maintenance to make money. “Our philosophy with respect to service is not to make a profit on service,” Musk said. “I think it’s terrible to make a profit on service.”
The shareholders applauded — the same shareholders that have sent Tesla’s stock price up nearly 650 percent over the past year. Yes, for now, Tesla only makes luxury cars, and its approach to service might seem like a luxury. But if it starts making cars regular people can afford, that applause for car dealers could be the sound of money spiraling down the drain.
I think hydrogen will become the new standard over electric, but that is just an opinion looking at the data. Hydrogen is the most abundant energy source in the universe, so it only makes sense to make this happen and produce affordable hydrogen cars over time.
Hydrogen is high in energy, yet an engine that burns pure hydrogen produces almost no pollution. NASA has used liquid hydrogen since the 1970s to propel the space shuttle and other rockets into orbit. Hydrogen fuel cells power the shuttle's electrical systems, producing a clean byproduct - pure water, which the crew drinks.
A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. Fuel cells are often compared to batteries. Both convert the energy produced by a chemical reaction into usable electric power. However, the fuel cell will produce electricity as long as fuel (hydrogen) is supplied, never losing its charge.

I would like to think Earth is part of the universe no? Hydrogen all around….
Musk countered this week by arguing that hydrogen fuel cells, even in the "best case," can't equal what lithium ion batteries currently offer in terms of cost and range. He also said such technology would require more cost-intensive distribution systems while posing serious dangers to consumers, since hydrogen is a flammable gas
But Mutolo added, "That said, the consumer should be wary of two things, hype and safety."
Mutolo said it wasn't likely that a driver would get more than 140 miles out of a 20-minute charge, and only that far if they were traveling less than 50 miles an hour.
"The numbers don't add up," Mutolo said.
On Friday, Musk had said that his supercharger network would soon allow cross-country travel from New York to Los Angeles -- free of charge, so to speak -- for drivers of the Tesla Model S sedan, which starts at about $70,000.
The super-charging stations are about 10 times faster than other available electric vehicle charging stations.
Mutolo also said that current lithium ion technology wouldn't safely allow such a powerful charge.
"It could potentially catch on fire. Not a good idea," Mutolo said.
It should be said here that Mutolo is a hydrogen fuel cell chemist, a competing technology.

...that gives me hope that one day we will be off the petro teet, at least for transportation.
So I can see the guy not thinking much of hydrogen cars. I don't.
Two obvious problems with batteries are the low speed of charge and the annoyance of having to change the battery every 500 charges or so. If one runs an EV battery 3/4 of the way down and charges it every week, the battery will last 8 years. Further, battery charging takes 1-2 hours. These numbers are acceptable if you use the car only occasionally, but they get more annoying the more you use the car. By contrast, the tanks used to hold gasoline or hydrogen fill in a matter of minutes and last for decades or many thousands of fill-cycles.
Another problem with batteries is range. The weight-energy density of batteries is about 1/20 that of gasoline and about 1/10 that of hydrogen, and this affects range. While gasoline stores about 2.5 kWhr/kg including the weight of the gas tank, current Li-Ion batteries store far less than this, about 0.15 kWhr/kg. The energy density of hydrogen gas is nearly that of gasoline when the efficiency effect is included. A 100 kg of hydrogen tank at 10,000 psi will hold 8 kg of hydrogen, or enough to travel about 350 miles in a fuel-cell car. This is about as far as a gasoline car goes carrying 60 kg of tank + gasoline. This seems acceptable for long range and short-range travel, while the travel range with eVs is more limited, and will likely remain that way, see below.

Cost is perhaps the least understood problem with batteries. While electricity is cheap (cheaper than gasoline) battery power is expensive because of the high cost and limited life of batteries. Lithium-Ion batteries cost about $2000/kWhr, and give an effective 500 charge/discharge cycles; their physical life can be extended by not fully charging them, but it’s the same 500 cycles. The effective cost of the battery is thus $4/kWhr (The battery university site calculates $24/kWhr, but that seems overly pessimistic). Combined with the cost of electricity, and the losses in charging, the net cost of Li-Ion battery power is about $4.18/kWhr, several times the price of gasoline, even including the low efficiency of gasoline engines.
Hydrogen prices are much lower than battery prices, and nearly as low as gasoline, when you add in the effect of the high efficiency fuel cell engine. Hydrogen can be made on-site and compressed to 10,000 psi for less cost than gasoline, and certainly less cost than battery power. If one makes hydrogen by electrolysis of water, the cost is approximately 24¢/kWhr including the cost of the electrolysis unit.While the hydrogen tank is more expensive than a gasoline tank, it is much cheaper than a battery because the technology is simpler. Fuel cells are expensive though, and only about 50% efficient. As a result, the as-used cost of electrolysis hydrogen in a fuel cell car is about 48¢/kWhr. That’s far cheaper than battery power, but still not cheap enough to encourage the sale of FC vehicles with the current technology.
My company, REB Research provides another option for hydrogen generation: The use of a membrane reactor to make it from cheap, easy to transport liquids like methanol. Our technology can be used to make hydrogen either at the station or on-board the car. The cost of hydrogen made this way is far cheaper than from electrolysis because most of the energy comes from the methanol, and this energy is cheaper than electricity.
In our membrane reactors methanol-water (65-75% Methanol), is compressed to 350 psi, heated to 350°C, and reacted to produce hydrogen that is purified as it is made. CH3OH + H2O –> 3H2 + CO2, with the hydrogen extracted through a membrane within the reactor.
You're going to have to come up with the requisite energy for freeing the hydrogen from whatever it's tied up in.
Today, most hydrogen is made from natural gas, some from electrolysis of water and some from bio-methane.
Automakers and bus builders use fuel cells to power their electric vehicles. They use a particular kind of fuel cell, known as a proton exchange membrane (PEM). The PEM fuel cells are stacked together, like slices in a loaf of bread, to form a fuel cell stack.
In its simplest form, a PEM fuel cell is two electrodes—the anode and the cathode—separated by a catalyst-coated membrane. Hydrogen from the vehicle’s storage tank enters one side of the fuel cell stack and air on the other side. The hydrogen is naturally attracted to the oxygen in the air. As the hydrogen molecule moves through the stack to get to the oxygen, the catalyst forces the hydrogen to separate into electron and proton.
How the vehicle works
The proton moves through the membrane and the electron moves to the anode. The electricity flows into a power module, which distributes electricity to the electric motor that turns the wheels of the car. The power module also distributes electricity to the air conditioning, sound system and other on-board devices.
At the cathode, the electron recombines with the proton, and the hydrogen joins with the oxygen to create the vehicle’s only tailpipe emission—water. Fuel cells produce electricity as long as fuel is supplied.

why spend 30-40 thousand on a new hybrid electric car when you can convert to Hydrogen/oxygen for only a couple grand and a few hours of work.
