Green hydrogen energy and enhance water.

Green hydrogen energy and enhance drinking water.
A Cornell University-led research team has developed a way to (generate green hydrogen) through solar-powered electrolysis of seawater. it also produces potable water.
A small hybrid solar distillation-water electrolysis device is key to the process, helping to produce 200 milliliters of hydrogen per hour with 12.6% energy efficiency,
The prototype measures just 4 inches per side, and if scaled up, it estimated it could reduce the cost of green hydrogen to just $1 per kilogram in 15 years. At the same time, this boon to next-gen fuel production could also help address the growing freshwater crisis.
Water and energy are both critically needed for our everyday life, but typically, if we want to produce more energy, we have to consume more water.On the other hand, if we need drinking water, because two-thirds of the global population are facing water scarcity. So there is a bottleneck in green hydrogen production, and that is reflected in the cost.
We see the wasted heat from solar cells as an opportunity instead of a drawback.We could use that heat to help warm seawater until it evaporates without affecting electricity generation, utilizing the full potential of the sun's energy.
How bad is a gas stove for our home's indoor air quality?
Creating green hydrogen without squandering precious freshwater resources which are key to making a high-purity, sustainable end product. it has also been a stumbling block for the industry.
Around two-thirds of Earth is covered in water, but the oceans hold about 96.5% of that. Unfortunately, the salt content makes it unsuitable for humans to drink unless processed through desalination.
Solar array deployment across the world is growing to harness the carbon-free energy the sun provides, while desalination plants are also increasing to help provide clean drinking water to people in need.
Combining the processes in one multifaceted device seems like a win-win for people and the environment.

Should we be harnessing the ocean to power our homes?
Absolutely
This is a highly integrated technology. The design was challenging because there's a lot of complex coupling,desalination coupled with electrolysis, electrolysis coupled with the solar panel, and the solar panel coupled with desalination through solar, electrical, chemical and thermal energy conversion and transport.
Now, for the first time, we can produce a sufficient amount of water that can satisfy the demand for hydrogen production. And also we have some additional water for drinking. Two birds, one stone.
There's even more potential for the device as a way to help cool down photovoltaic panels, which could help improve their efficiency and extend their lifespan.
We want to avoid carbon emission, avoid pollution. But meanwhile, we also care about the cost, because the lower cost we have, the higher market potential for large-scale adoption.
We believe there is a huge potential for future installation.

Solar Generation in Night hrs

How to get get Solar generations in Night        While standard solar panels cannot generate electricity at night,     New technologies are being developed to address this limitation.      These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources.  Key Concepts and Technologies :- 1) Anti-Solar Panels (Thermo-radiative Cells):- How they work:-    These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity.    Nighttime energy:-     They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power.  Potential:-  ...

Hydrogen at home — It's the end of solar and wind power

  Hydrogen at home — It's the end of solar and wind power         Statement "1000 pounds" per day of hydrogen at home — It's the end of solar and wind power in the world" is not accurate.     While hydrogen can be produced from renewable energy sources like solar and wind power, it's not a replacement for those sources themselves. Hydrogen production via electrolysis, using renewable electricity, is a promising avenue for decarbonization, but it doesn't negate the need for solar and wind power as direct energy sources.  Cause behind its is as under. Hydrogen as an Energy Carrier:-     Hydrogen is an energy carrier, meaning it stores energy produced elsewhere (like from solar or wind) and can be used to power fuel cells or for other applications.  Electrolysis:-     A key method of producing "green" hydrogen involves using electricity from renewable sources (like solar and wind) to split water into hydrogen and oxygen throu...

Lift off the ground during seismic activity, minimizing damage in Japan

Lift off the ground during seismic activity, minimizing damage in Japan     Japan has developed a technology that allows houses to literally lift off the ground during earthquakes, protecting them from damage.    This is achieved using a system of compressed air and sensors that inflate an airbag under the house, lifting it a few centimeters during tremors. The house then gently settles back down when the shaking stops.      Japan has developed innovative earthquake-resistant technology that allows houses to lift off the ground during seismic activity, minimizing damage. This is achieved through systems like the one developed by Air Danshin, which uses compressed air to lift houses on airbags. When sensors detect tremors, the airbag inflates, raising the house a few centimeters and preventing it from shaking violently with the ground.    More detailed explanation: Airbag Technology:- Air Danshin has pioneered the use of large airbags placed b...
