Imagine producing fuel in your own home using a man-made leaf, sunlight and water. This idea is now reality, thanks to Harvard researchers who are discovering and creating new processes and new materials to change the energy landscape.

I've been talking about this concept for years. I'm glad it's finally s reality.
CNet, please make moar awesome science videos like this. Thx
Don't think too fast. This does not mean that anything innovative has happened. This method is called electrosis. It separates molecules using electricity. You can do it with a AA battery, a paper clip, and a glass of water.
Electrolysis*
U can do this with sunlight
The thing is : Now you can use this process without using electricity, but with sunlight. This means the way Nitrogen is "extracted"is nonpolluting. Which ofcourse is good for the environment...
Great, now let's put it to good use.
Electrolysis of Water? Oh Harvard U so smart.
As demonstrated 35 years ago in Goliath Awaits.
i thinki this is the most original idea of getting hydrogen from harvard
About time science!
The fuel companies are going to fund so hard against this.
exactly

Awesome!!!
Wish I went to Harvard sometimes.
i wish i owned Harvard
I did but got kicked out because i don't have "knowledge" i only know memes on internet.
WOW!
Better than a real leaf! Damn
unreal damn that's cool
Why do top universities often comes up with these things? Why not other universities?
I think other schools are less into science and more into sports
great idea !!! soon we will be out of water aswell.
Put that shit on my house ASAP
We're beating god at his own game
Does it work with salt water? Because the world is running out of freshwater and if we use freshwater as fuel, we might really ran out of it faster.
but i think Microsoft has created new thing that make freshwater or something
Beating "god" at his own game..nice work!!
Some Elite Banker/Corporation will kill the creator of this or patent this thus withholding it from Mankind..
you seem to have some higher learning. tell me more
Of course not, this is at best a very nice and small electrolysis cell, but it would never replace oil or pose a threat to it because thermodynamically it'll always be less efficient than regular solar panels
+Mau dL I thought the big picture was that it creates oxygen and uses Co2 as energy?
MrJerrybravo Not at all, this thing absorbs energy from sunlight then passes a current thru the water to separate oxygen and hydrogen with a well known process called electrolysis, however this is thermodynamically only using the hydrogen as an energy vector, that is to say that the energy is coming from the sun, the hydrogen is just a way to store it, in other words you need more energy to separate water into hydrogen and oxygen that the energy you'll get from burning the hydrogen, even if you did it with 100% efficiency the limit is in physics, not engineering.
Something that takes CO2 which we obviously have too much of and makes energy. Let's hope this gets to market quickly.
it won't it's cheap, elites won't make money. plenty things like this have been discovered but same old story
The elites won't make money when the seas become so acidic the plant life dies and 75% of our oxygen source is cut off. At worst, other countries will demonstrate it's value and we'll begrudgingly take it up lears later.
+525Lines That could be years from now, people want to make money today. That's all that matters.
525Lines Exactly
"īsəˈprōpəl" if you're commenting on science please use the correct pronunciation
why not just use the hydrogen in hydrogen powered vehicles
eye-so-pro-pill groan
This is witchcraft!
Harvard you are taking steps backward i think the public wants hassile free ways of transportation and other things as well without the need of filling up!
