EV's are the worst idea to date. They are expensive, expensive to maintain, not very green due to all the mining and rare materials needed for batteries that can take hours to recharge after a few hundred miles. This is opposed to hydrogen that can take 90 seconds to fill up and go and hydrogen is everywhere. The challenge was how to store hydrogen and not Japanese found an affordable. The following is from interestingengineering.com and written by Ameya Paleja.
Researchers at the RIKEN Center for Emergent Matter Science (CEMS) in Japan have found a simple and affordable way to store ammonia, an important chemical in a range of industries. The discovery could also help in establishing a hydrogen-based economy.
Ammonia, chemically written as NH3, is widely used across industries ranging from textiles to pharmaceuticals and is an important component in the manufacture of fertilizers. For its current use, ammonia is stored in pressure-resistant containers after liquefying it at temperatures of -27 Fahrenheit (-33 degrees Celsius).
Alternate methods of storing ammonia in porous compounds have been explored. The storage and retrieval process can be achieved at room temperature, but the storage capacity of these compounds is limited.
A research team led by Masuki Kawamoto at RIKEN CEMS has now found that perovskites, crystalline structures associated with improving energy conversion efficiencies of solar panels, can also serve as an excellent medium for the storage and retrieval of ammonia.
Perovskite as an ammonia carrier
Kawamoto's team found that the perovskite ethyl ammonium lead iodide (EAPbI3) reacts with ammonia at room temperature and pressure to make lead iodide hydroxide, or Pb(OH)I. Ethyl ammonium lead iodide has a one-dimensional columnar structure but, after reacting with ammonia, forms a two-dimensional layered structure.
Ammonia is a highly corrosive gas, but the chemical reaction with the perovskite allows for its safe storage that does not need any special equipment to store it either. The retrieval process is also very straightforward. Under vacuum, ethyl ammonium lead iodide can be heated to 122 Fahrenheit (50 degrees Celsius) to release ammonia gas.
In comparison, ammonia stored in porous compounds needs temperatures around 302 Fahrenheit (150 degrees Celsius) for recovery.
Moving to a hydrogen economy
The discovery of the role of perovskite is very important since it also offers a way to store hydrogen. Each molecule of ammonia packs three atoms of hydrogen and packing 20 percent of the weight of the molecule.
On its own, hydrogen is highly combustible, but ammonia does not combust easily, making it a good medium to store it until needed.
The perovskite-ammonia reaction is fully reversible, and the perovskite can be reused to store ammonia again after retrieval is completed. Interestingly, the perovskite also changes color to white when it stores ammonia and returns to its original yellow after ammonia is retrieved. Scientists can exploit this feature to make color-based sensors to determine the amount of ammonia stored in the perovskite.
Our attempts to move away from fossil fuels are likely to prove futile if we cannot find alternatives to carry out tasks like long haul and heavy transport. Hydrogen's power density is almost thrice that of gasoline or diesel, but its combustible nature brings high risk.
A simple and affordable method where hydrogen can be extracted at the site of its need, only in amounts that it is required, will pave a quicker way toward a hydrogen-based economy in the near future.
The research findings were published July 10 in the Journal of the American Chemical Society.
So are you still a fan of EV's that will end up costing you much more than a gas power car, or would you consider hydrogen power cars would involve some minor updates to today's technology and uses an element that is abundant in the Universe. So would you consider hydrogen over EV?

I have lost a lot of faith with the Medical Community and the Governments over the last several years, but there are a few good things that can raise above the corruption and the pushing of drugs a new approach to heal people. The following is from www.gaia.com and written by Hunter Parsons that does not involve any drug or pushing an ineffective so called vaccine that the drug company is not held accountable in any way but they use sound! The use of sound can regrow bone tissue! Here is the story:
"The future of regenerative medicine could be found within sound healing by regrowing bone cells with sound waves.
The use of sound as a healing modality has an ancient tradition all over the world. The ancient Greeks used sound to cure mental disorders; Australian Aborigines reportedly use the didgeridoo to heal; and Tibetan or Himalayan singing bowls were, and still are, used for spiritual healing ceremonies.
Recently, a study showed an hour-long sound bowl meditation reduced anger, fatigue, anxiety, and ...
Not a fan of a Defense Agency studying Anti-Gravity and other Exotic Tech, but if the commercial world and make this technology cheap that will change our world yet again. The following is about three minute read and from www.gaia.com. The below was written by Hunter Parsons:
"Wormholes, invisibility cloaks, and anti-gravity — it’s not science fiction, it’s just some of the exotic things the U.S. government has been researching.
A massive document dump by the Defense Intelligence Agency shows some of the wild research projects the United States government was, at least, funding through the Advanced Aerospace Threat Identification Program known as AATIP.
And another lesser-known entity called the Advanced Aerospace Weapons System Application Program or AAWSAP
The Defense Intelligence Agency has recently released a large number of documents to different news outlets and individuals who have filed Freedom of Information Act requests.
Of particular interest are some 1,600 pages released to Vice News, which ...
As our technology gets better we are discovering more about the history of mankind and pushing the timeline back further and further. The following article is from www.gaia.com and written by Michael Chary that discusses this new find that changes the historical timeline:
"Over the past decade, there have been a number of archeological revelations pushing back the timeline of human evolution and our ancient ancestors’ various diasporas. Initially, these discoveries elicit some resistance as archeologists bemoan the daunting prospect of rewriting the history books, though once enough evidence is presented to established institutions, a new chronology becomes accepted.
But this really only pertains to the era of human development that predates civilization — the epochs of our past in which we were merely hunter-gatherers and nomads roaming the savannahs. Try challenging the consensus timeline of human civilization and it’s likely you’ll be met with derision and rigidity.
Conversely, someone of an alternative...
Not sure if you have heard of a show on YouTube called "The Why Files". If not you should check it out it is interesting and has some humor with it on different subjects. Last weeks was on a different theory how the Universe works and how main stream Science is attempting to shut it down like is always seems to do if it goes aguest some special interest. Today it is akin to what happened to those who questioned the Earth was the Center of the Universe that main stream so called Science all believed during the Renaissance period, They called any theory that the Earth was not the Center of the Universe misinformation. Does this sound familiar today? People laughed and mocked people like Leonardo da Vinci, Nicolaus Copernicus, Georg Purbach as crack-pots, conspiracy theorists, nut-jobs and they were suppressed and even imprisoned for their radical thoughts and observations. Again it sounds like today in so many ways. In any event this is a good one to ponder and see even if a bad idea ...
Seemingly chaotic systems like the weather and the financial markets are governed by the laws of chaos theory.
We all have heard about chaos theory, but if you have not or have forgotten what chaos theory is well here you go from interestingengineering.com:
"Chaos theory deals with dynamic systems, which are highly sensitive to initial conditions, making it almost impossible to track the resulting unpredictable behavior. Chaos theory seeks to find patterns in systems that appear random, such as weather, fluid turbulence, and the stock market.
Since the smallest of changes can lead to vastly different outcomes, the long-term behavior of chaotic systems is difficult to predict despite their inherently deterministic nature.
As Edward Lorenz, who first proposed what became commonly known as the Butterfly Effect, eloquently said, "Chaos: When the present determines the future, but the approximate present does not approximately determine the future.""
You may have heard the term about chaos theory as a butterfly flaps its wings in Brazil,...
I for one have lost trust in Medical Doctors due to COVID and reflection that they seem to push pills for everything and untested so called vaccines that is using a unproven technology because the Government and the Medical Boards of the State told them to. There are a very few exceptions. Thus they do not address the key problem just prescribe more and more pills to keep you alive an sick longer for them and Big Phama to profit from you. Will AI do any better? Well that depends on what was used for the training of AI. If it also pushes pills and vaccines without question then you have the same problems noted above. However, if the AI Training includes all possible forms of treatment and they zero in on the right issues for the true problem then there is possibilities they would be way better than most of the current Medical Doctors today.
