- casspa, on 07/31/2008, -5/+217A great day for science.
- felsoule79, on 07/31/2008, -8/+166go MIT!
- akchrs, on 08/01/2008, -7/+150...and I will call this "storage device" a battery.
- rob2oo4, on 08/01/2008, -7/+91MIT just bitch slapped the Electric Company
- deepdiggdude, on 07/31/2008, -8/+75http://www.physorg.com/news136738014.html
Same story from a site all diggers should check daily. - anyone4apint, on 08/01/2008, -10/+64The guy has a beard therefore I can confirm that he is indeed a high class professor. As I am sure you will agree, any professor without a genuine beard is a faker.... good job this guy is legit.
- pckbeta, on 07/31/2008, -1/+49Awesome. Way more promising than hoping on the existence of hydrinos.
- inactive, on 08/01/2008, -7/+51"storing energy for use when the sun doesn't shine"
At first I thought this said "WHERE the sun doesn't shine". My only thought was"OUCH!" - CMaff24, on 08/01/2008, -2/+43im just waiting for the singularity
- synthpop, on 08/01/2008, -1/+32Exxon's nightmare of free energy for all is also (finally) coming true
- inactive, on 08/01/2008, -6/+36Tesla's dream of free energy for all is (finally) coming true.
- Yez70, on 08/01/2008, -6/+35It means NOTHING until it's actually being USED. We hear about these breakthroughs 10 times a week on Digg, yet never see many of them come to fruition.
- flyzipper, on 08/01/2008, -2/+31Rising gas prices are concentrating people from the suburbs to urban areas, but I wonder if this type of progress in personal solar generation will eventually allow people to return to the suburbs ... to increase their potential solar footprint.
High density urban areas will still rely on the grid because the surface area which can collect solar is shared by more people. Suburban dwellers have their own parcels of land which are essentially their own private solar footprint.
In the future, that more land you own, the more power you will have access to? - inactive, on 08/01/2008, -2/+30The catalyst which makes the process more efficient is new.
- govsucks, on 08/01/2008, -2/+29Dugg, I want to start manufacturing these things today!
- inactive, on 08/01/2008, -1/+25Yeah, guys it was tongue-in-cheek. Jeez, tough crowd around here...
- rootx, on 08/01/2008, -3/+26i would say A great day for humanity.
- gfxlonghorn, on 08/01/2008, -6/+28Am I missing something or are they claiming electrolysis as a major discovery...?
- perfectfire, on 08/01/2008, -1/+22I don't think you get it. Energy that isn't used during the day would be used to split water (apparently at almost 100% effeciency) to be used at night. This is assuming you have enough panels and sunlight that you have more energy coming from that panels that you are using during the day.
- Loonacy, on 08/01/2008, -0/+20I'm just waiting for the breakthrough in manufacturing and materials for solar panels. That's when you'll see solar energy start to take off.
- govsucks, on 08/01/2008, -0/+20while it is better to get the info right from the source, deepdiggdude is correct. physorg should be daily on the browse list. I sure as hell never miss a day. I digg thee up.
- dafragsta, on 08/01/2008, -0/+19Excellent work Soundwave, though I'm sure it's energon cubes.
- inactive, on 08/01/2008, -28/+45Pssh yeah...If you HATE AMERICA! The Sun is for communists and terrorist sympathizers. The only way we will win the War on Terror is if we drill every square inch of this country. Anyone who uses any kind of alternative energy is a looney liberal who gives comfort to the enemy.
- cdigioia, on 08/01/2008, -0/+16Holy crap in a taco! This is the 150th consecutive week that a HUGELY revolutionary energy technology has come out on Digg! It's a great time to be alive isn't it?!
- punkcat, on 08/01/2008, -0/+16they won't get it unless you write /sarcasm at the end.
i particularly liked the drill every square inch bit. - kh99, on 08/01/2008, -9/+24"The key component in Nocera and Kanan's new process is a new catalyst that produces oxygen gas from water; another catalyst produces valuable hydrogen gas."
Um..so how does a catalyst produce oxygen gas without also producing hydrogen gas? Must have to create some other substance to capture the hydrogen, then something would have to be used up in the process, wouldn't it?
Anyway, I hope this doesn't end up being "cold fusion" for the 2000's. - mdoom, on 08/01/2008, -2/+17sadly its a must for what I refer to as, diggers of olde.
I feel digg is overrun by 14 year old fan boys anymore...but when digg first started, heck, still even just two years ago, diggers where more just the science tech. guys..i miss that. :-) - inactive, on 08/01/2008, -0/+13People all over the world even in remote locations can have electric power given solar and this invention. Lets hope they are successful in implementing it.
- DavidGX, on 08/01/2008, -0/+13Stop digging this guy down, retards, he's kidding.
- joebloe3000, on 08/01/2008, -3/+16ALREADY BEING DONE....
Maybe his catalyst could improve the electrolysis process...
Check out this link... (prototype solar/hho gas/geothermal house)
http://www.youtube.com/watch?v=xEdQRVQtffw&feature ... - zephc, on 08/01/2008, -4/+17I think you need to call the Henry Dreyfus Professor of Energy at MIT, and let him know about his mistakes.
- TheXuu, on 08/01/2008, -0/+12@Neiby Its a glitch in the system. It happens when they rewrite something.
- Laminarcissus, on 08/01/2008, -0/+11Actually, they're pissing on us.
- Laminarcissus, on 08/01/2008, -4/+14Yeah, who the f*ck are these MIT guys anyway?
- MxM111, on 08/01/2008, -2/+12May be my chemistry is rusty, but scientifically I do not see what is new. If you put electric current through water with right catalysis, then you can split it into oxygen and hydrogen through the process called hydrolysis (if I remember correctly). This is how you make this HHO gas. You can also do it in strong magnetic field, though less efficient.
The article does not go into details, but may be it is some kind of engeneering improvement, like cheaper catalysts, or higher efficiency...
I hate when the popular journals/websites describe minor developments as something worth 10 times Nobel prizes, and solving world hunger at the same time, without giving much details. - Ultomato, on 08/01/2008, -0/+10then we shall fight in the shade
- synystar, on 08/01/2008, -0/+10It won't be any different than every other time new technology trumped old technology. Either these companies will convert their resources into something different and more viable - or they will fail. People may lose jobs but the world will move on and you'll still have cheaper, more efficient energy that runs at no cost to the environment.
- mickstephenson, on 08/01/2008, -1/+11Also a great day for space exploration as this will surely become the cheapest way of producing rocket fuel
- Taiyoryu, on 08/01/2008, -0/+10http://en.wikipedia.org/wiki/The_Great_Wave_off_Ka ... by Hokusai
- maseone, on 08/01/2008, -0/+10good point, with one flaw. the whole world isn't New York.
98% of the Urban space in the US and abroad is much like the "suburban" space you describe.
im not sure what my point was, but just pointing that out. - krnldmp, on 08/01/2008, -7/+16A solar revolution would be a cheap 80% efficient photovoltaic panel. Turning electricity into hydrogen better isn't quite.
Just so you know, it doesn't really help the cause to yell REVOLUTION every time someone makes a tiny advance. - alburkha, on 08/01/2008, -5/+14But what will we do when we have to torch the skies to prevent the machines from obtaining their energy?
- kh99, on 08/01/2008, -1/+10zephc - I'm not saying he made a mistake, more likely it's the article that's unclear. I'm basically asking if anyone can explain it. Of course I should have known that the replies would be from people who don't even get the question.
borez - yes, when you split water you get hydrogen and oxygen, that's my point. If you read the section I quoted, it talks about how one of the catalysts works, and then the article mentions that another is needed to get hydrogen. My question is, if you have the cobalt/phosphate catalyst making oxygen gas, why would you need another catalyst to get hydrogen? - dafragsta, on 08/01/2008, -1/+10... actually, it sounds like this was from a university.
Then again, I guess they aren't giving away education are they? - ralphodog, on 08/01/2008, -5/+14So more efficiently storing energy generated from one of the most inefficient methods is going to start a revolution? More efficient methods (solar thermal) already have efficient means of storing energy during the night. This invention is pure hype as it is only improving a method that is still substantially behind others.
- BobScratchit, on 08/01/2008, -1/+10Brilliant!
- truman48, on 08/01/2008, -6/+15Enerjon cubes, duh?
- scabbers, on 08/01/2008, -0/+9I think it might be more economical for a city to have a grid system where commercial solar/hydrogen sites sell the electricity to people who dont have a roof and the people who want their own roof system can sell their excess juice to the grid.
North Africa would LOVE to sell its "sunlight" to europe on that kind of basis. - Laminarcissus, on 08/01/2008, -0/+8I'm no chemistry major, but could the hydrogen be bound to the first catalyst after the first reaction, and then need the second catalyst to be made free?
