Thanks, antiterror13.

It"s a neat idea actually. The only problem is how to generate the electricity to power the engine in the first place. It could be fuel cell or if you want to go super high power, it could be powered by nuclear reactor.

not to burn one gallon of oil (and to be green), will it burn ten thousand gallons of oil to get hydrogen? LOL

'Artificial leaf' concept inspires research into solar-powered fuel production

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel.


The platform developed by the Brown School of Engineering lab of Rice materials scientist Jun Lou integrates catalytic electrodes and

that, when triggered by sunlight, produce electricity. The current flows to the catalysts that turn water into hydrogen and oxygen, with a sunlight-to-hydrogen efficiency as high as 6.7%.

This sort of catalysis isn't new, but the lab packaged a

layer and the electrodes into a single module that, when dropped into water and placed in sunlight, produces hydrogen with no further input.

that, they say, should be simple to produce in bulk.

"The concept is broadly similar to an artificial leaf," Lou said. "What we have is an integrated module that turns sunlight into electricity that drives an electrochemical reaction. It utilizes water and sunlight to get chemical fuels."

Perovskites are crystals with cubelike lattices that are known to harvest light. The most efficient perovskite

produced so far achieve an efficiency above 25%, but the materials are expensive and tend to be stressed by light, humidity and heat.

"Jia has replaced the more expensive components, like platinum, in perovskite solar cells with alternatives like carbon," Lou said. "That lowers the entry barrier for commercial adoption. Integrated devices like this are promising because they create a system that is sustainable. This does not require any external power to keep the module running."

Liang said the key component may not be the perovskite but the polymer that encapsulates it, protecting the module and allowing to be immersed for long periods. "Others have developed catalytic systems that connect the solar cell outside the water to immersed electrodes with a wire," he said. "We simplify the system by encapsulating the perovskite layer with a Surlyn (polymer) film."

The patterned film allows sunlight to reach the solar cell while protecting it and serves as an insulator between the cells and the electrodes, Liang said.

"With a clever system design, you can potentially make a self-sustaining loop," Lou said. "Even when there's no sunlight, you can use stored energy in the form of chemical fuel. You can put the hydrogen and oxygen products in separate tanks and incorporate another module like a fuel cell to turn those fuels back into electricity."

The researchers said they will continue to improve the encapsulation technique as well as the solar

themselves to raise the efficiency of the modules.

There are various other individual research results proving that artificial leaves can provide the required Hydrogen supply to transit to Hydrogen society.

Funny how things turn out in the Trump Administration. First the Tech Companies and Pentagon seek Trump to section chinese tech companies for being naughty and a security threat. So Trump put them on the entity list.
Then US tech companies objected and Pentagon objected to further sanctions as it is hurting American interests.
Then Pentagon turn around and ask of more sanctions on China.
This timeround, Trump defended high tech trade with China and fired Pentagon hightest personel in the Whitehouse for arguing for more sanctions on a list of high tech industries which Trump said are rediculous and have nothing to do with National Security.
While at the same time US Defence Secretary Mark Esper is telling Allies that China is the main adversary and they are not to allow Huawei to built up their 5G otherwise they would risk their intelligent co-operations and sharing with the US.
What is going on there?

Its call the great dilemma of a declining power.

Few months ago, I think what the future headlines in US will be like in say 2028....they will probably be something like :

The Chinese Regime is abusing its huge tech market by unfairly locking out US semiconductor players..
The Chinese Should Adhere by Free Market rule and let US Chips In
Chinese Chip Makers Are growing at the expense of US' players.
China must open up her semiconductor market

All while conveniently forgetting that the US admin banned US started selective chip export bans in 2018.

Interesting concept. The Americans and Russians have played around with nuclear powered aircraft and missiles so if a powerplant can be miniaturised... but then that would just be a nuclear powered engine with a slightly different method to achieve propulsion. Wonder how developed this concept is. Maybe a combination of Russian miniature reactors and this system can be fruitful. As far as I know, there are no miniaturised reactors developed by China yet.

Have you ever heard the phrase 'carbon society', basically our modern society is possible with carbon based energy like oil, natural gas and coal.
We are coming to the age where those carbon based energy sources can be replaced with Hydrogen through fuel cells and Nuclear fusion.
That is what a Hydrogen Society means.

Oh yes, if only the electricity needed for the reaction to produce hydrogen is from solar panels, it's the greenest way almost free and infinite. Fuel is the best energy storage without any losses like batteries.
