  A hurricane is still a temporary removal of literally orders of magnitude more water than all the cars on Earth would be. It can take days or weeks for all that water to return from the hurricane to the rest of the water cycle. And those cars are continually putting water back in the atmosphere. Does
context: This has been around for years and the process is very well understood. The problem is cost, and so far no one has cracked that nut.
  This is just another vaporware scamstarter >
  
  Yep. Just a way to burn up grant money. >
  
  This is great... for youtube channels debunking this kind of stuff. >
  
  tldr: condensates water from the air by allowing it to.. condensate on a thin mesh, then it's converted through electrolysis which is not efficient (also stated in the article)
  let's say you could probably run your espresso machine from it.. maybe >
  
  Yeah, I hate to be the downer all the time, but this isn't as big of an invention as it's made out to be. The amount of hydrogen gained is low and the cost to build such a thing is high, and I mean production and matieral, not monetary. >
  
  EPFL scientists have developed a prototype of a solar-powered device capable of extracting water from the air and converting it into hydrogen.
  A team of engineers from the Swiss Federal Institute of Technology Lausanne (EPFL) drew on plant leaves as inspiration for the device, which they say can be easily manufactured and used on a large scale.
  When exposed to sunlight, the device absorbs water from the air and produces hydrogen. The hydrogen produced in this way could be used as fuel or for the long-term storage of solar energy, the authors wrote in the scientific journal “Advanced Materials” on Wednesday.
  The main innovation in the model are the novel electrodes, which have two key properties: they are porous, in order to maximise contact with water in the air, and they are transparent, in order to maximise solar radiation on the semiconductor coating.
  Modest yield
  In its current form, the prototype can already produce hydrogen when exposed to the sun’s rays. However, the scientists admit that efficiency is still “modest”.
  The next step is to optimise the prototype, including through determining the ideal fibre and pore size as well as the most suitable materials.
  To produce the electrodes, the researchers fused glass fibres together at high temperatures. The resulting platelets were coated with a thin layer of fluorine-reinforced tin oxide – a material known for its conductivity, robustness and ease of production. The plate was then given another coating: a thin film of light-absorbing semiconductor materials. >
  
  I guess it is to late to buy shares? >
  
  Please integrate this eco-friendly development into all of our infrastructure. This will change the world! >
  
  Yes sorry I forgot that part 😭 >
  
  I saw a news report on somthing similar local to me about 15 years ago so assume it has been killed before!! >
  
  Am I the only one who thinks, there's an unknown danger of extracting water from our air, split it into hydrogen, burn it in cars and expect everything to still be in balance, as soon as we do it on a great scale?
  I feel like at this point, humanity prefers nuking the entire planet, with the hope of stopping climate change, to actually change our behavior, economy and infrastructure. >
  
  Uhhh, you know that when hydrogen is combusted, it turns back into water, right? >
  
  Yes, I am aware of that. Imagine the air as a river. We caused great damage, by building dams, rerouting rivers etc. Why? Because our ecosystem not only cares on the amount of water in it, but also where and in what amount the water is in the system. If we start extracting water from air on a great scale and putting it back, by burning it, nobody can say, what the actual effect is going to be, because our ecosystem is extremely complex and can't be simulated in it's entirety. >
  
  If we took water from the air, water from the ocean would just evaporate and replace it. There's no way humans could ever take enough water from the air that the ocean wouldn't be able to replenish it. Especially since we'd be using the hydrogen to burn or run through a fuel cell which turns it right back into water. >
  
  As I said, this has never been done before on a big scale. Humanity has a massive hunger for energy and this hunger is growing rapidly.
  If the scale is big enough, this can cause an involuntary geo-engineering effect.
  This technology means, we are transporting water from a to b. Hydrogen cars, hydrogen planes, hydrogen trains, hydrogen power plants, Industry fueled by hydrogen etc.
  Hydrogen is transportable all over the world. We will not just use it at one place.
  The extraction will probably take place in areas with high humidity, like Southeast Asia, and been used in areas with high energy demand, like Western Europe.
  This can cause shifts in rainfall, humidity, etc. >
  
  A hurricane locks up so much water that it drops 2.4 trillion gallons of water per day. Even if every car had hydrogen fuel cells, we would be locking up about 60 billion gallons at a time. Notice the scale difference? >
  
  
  A hurricane is not permanent.
  A hurricane is already part of the ecosystem.
  A hurricane mostly gets its water from evaporated ocean water and not out of the air.
