Will China, internation big oil and the oligarchs snatch up the patents on this sea water hydrogen fuel cell technology to maintain their strangle hold on energy production?
Pass the salt. Good only for those hoax deniers with mansions on the beach? Should lower sea levels.
They also found that hydrogen-powered drones have 10 to 20 times the range and the ability to instantly refuel when powered by hydrogen
Where does the electricity come from?
New Tech Transforms Sea Water Into Hydrogen Fuel for Cars; This miracle system produces more energy than it uses or perpetual motion discovered.
That is usually how it’s done with a monopoly wanting to hold on to it’s cornered market. A lot of great and creative inventions have probably been ‘put to sleep’ in this way.
I’ll reserve my applause until they can prove this is efficient energy. You can’t get more energy out than you put in without a natural potential energy source providing the difference.
My hunch is that the apparent hydrolysis process that this entails requires massive amounts of energy input. Just rearranging the furniture in the room, essentially.
What is the ERoEI and where do you get the electricity?
How much energy does it take to extract the hydrogen? A lot more than you get out of it I’ll bet. This is the achilles heel of most of these “alternatives”.
Hydrogen would be better than driving around with these lithium time bombs. The question is how to make it economical.
And where does that electricity come from?
What’s the efficiency of the end to end system and how does that compare to the efficiency to taking oil from the ground refining it into gasoline and delivering it at the gas pump?
Soo, THIS is OK, but desalinization isn’t. OK, got it.
This assumes the allowing Americans the freedom to travel outside their neighborhood doesn’t violate the Deep State plan....
They’d have all of the salt 🧂🧂🧂 they’d ever need!!
In the last two months, I have seen like 25 articles or TV reports on new miracle technologies that will help replace carbon based energy.
All of it is pie in the sky political propaganda.
It's no earth-shattering discovery that hydrogen can be separated from water (it is, after all, H2O), the crux of the biscuit is, how much does it cost, and how much pollution does the process create.
Thew article does say, the method "...extracts hydrogen from the ocean by funneling seawater through a double membrane system, using electricity...." And since the single greatest source of power generation in the US is coal-fired steam plants, that makes this coal and/or steam-powered hydrogen.
The only relevant questions, questions that the article goes nowhere near addressing, is "How much?" How much does it cost, and how much pollution is created in its name.
No matter how you make the hydrogen you still have to contain it in a heavy pressure vessel
That pressure vessel constitutes a danger of fire and explosion in a motor vehicle accident.
Compared to a gasoline vehicle the BTU/lbs hydrogen vehicle is far better which means more miles/lbs.
The hydrogen car is going to have a greater dry curb weight because of the heavy fuel container.
My Opinion is that any electric car starts with a disadvantage simply because of the weight of the fuel storage container.
Battery or pressure vessel; the extra weight is an unnecessary burden when gasoline is easily available and cheap.
It’s not the generation of hydrogen which is the issue.
It’s the storage of it that poses a technical challenge, i.e. cost vs. safety.
There are technical solutions to make it safe, but those make the cost skyrocket.
To date, regardless of the sales pitch, nothing beats gasoline and diesel specific to cost, safety, practicality (storage, start time, ambient temperature range, pollution) and energy density.
Theoretically, a turbine would be far better than a conventional Otto engine. Turbines are factually more efficient.
But even there you have a lot of problems, exhaust heat, start up time, the engine doesn’t like to vary it’s speed or run slow but would rather just go balls to the wall all the time (turbines like to run close to their limit).
All solutions other than the diesel or otto engine carry with them some serious drawbacks which make them less desirable overall, IMHO.
Sadly, the diesel which is a bit more efficient than the otto engine has gotten a bad rap, but is actually extremely clean today. In fact, if you look at the efficiency of most of these otto and diesel engines and how clean they have become, it’s actually quite impressive.
But, someone decided to label a lithium battery powered car with the green tree goddess seal of approval. Electric = green, and because folks today are like Pavlov’s dog, conditioned to drool as soon as they hear the term green, there is no more debate, even though these cars come with their own laundry list of environmental and even social issues.
