where is this tech…
He’s been diddling with this for a decade, never made a big one. What’s
wrong? Is it just that it’s not as efficient as electrolysis and PV cells
to do the same thing? I really wonder about Dan Nocera sometimes.
One side cobalt-phosphate based catalyst compound. The other side
nickel-molybdenum-zinc junction. I like all energy challenges since Daniel
Nocera is a person I admire. All this story of artificial leaf sounds
excellent except 1.Nickel, molybdenum and cobalt are not cheap at all; 2.
in the nature a leaf do not last for a long time (typical couple of
months), so probably Nocera’s artificial leaf also will face the big
challenge of relative quick degradation and oxidation. I am not a chemical
expert but probably the fact that one side contains zinc, it is maybe good
and bad at the same time. Like alkaline batteries a large amount of zinc
increases voltage difference between poles, but unfortunately the drop down
voltage once the inside environment starts to degrade it makes the battery
almost impossible to re-use.
With all the inventions and innovations over the years, where do they all
go? And, even if all the green tech was implemented, the end user’s cost
will not go down, because its only about increasing profits. People don’t
want huge wind turbines, and solar panels on the top of their house. Thats
why they’re allowed on the market. Commercial scale energy is about that
convenience… just plug in to the grid….. The only thing that will truly
reduce the consumer’s cost is something that produces power on site. The
benefits of anything that puts power on the grid will not be passed on to
the consumer except for the benefit of saving the environment. Even if the
cost of producing commercial scale energy was absolute zero… you will
still be paying the same…. but maybe and probably more.
This is pretty cool but something tells me that I doubt it will ever become
mass produced and I don’t know why.. :(
where is this tech…
plant them on mars so we can get out of here
What about with salt water. That’s the only way it’d be practical. U can’t
use the fresh water… we already pay enough for it.
What is the initial cost of leaf? I am not sure exactly it is viable or not
but If you think about 5 years probably it may take more than 10 years.
Heh, who needs fusion reactors when we’ve got stuff like this? : P
The world has a larger issue with fresh water… I wonder if you could use
desalinized water to run a water desalinization plant with a net gain?
Five years?Wanna a bet?20 Years will pass and i’m absolutly sure this wont
be in mass production or general use and you can start counting the
years.In a year or two fronm now you will not ear any news from this guy
and his invention anymore.

FYI +glyn moody
So cool… I can’t wait until it come onto the market! Projects like this
are where our energy dollars should be going! Not fracking or pipelines…
It does electrolysis and gives off oxygen and the hydrogen is stuck on the
zin-nicketl-molybdem side? How do you get it out?
Renewable power is energy that is produced from natural procedures that are
consistently refreshed. This includes sunshine, geothermal energy heat,

He shows the metallic leaf, and demonstrates it, but then switches to a
solar panel to power electrolysis to make H & O for the fuel cell. Kind of
a disconnect! Why not show producing the H & O from the Metallic leaf!? I
must have missed him saying that they are sill working on scaling it up.
In other words, they don’t have a even a toy setup working system
end-to-end. No calculation was given for the number of sq meters of leaf
and daylight that would be needed to split all those bottles of H2O every
day. People aren’t going to power their electric stove or car from this,
that’s for sure. Convert water heater,stove, dryer etc to natural gas??
Better to heat water with sun, whoops! Need many many sq meters of
sunlight to heat water AND generate power. Cover roofs with this stuff?
Show me the numbers. Solar flux == enerqy per square meter? Do you know?
5 years is probably not realistic. It has to be a lot cheaper, it must last
for a long time and at the same time produce enough to run a house or
whatever. This has not been done all at once, and some big pieces are still
missing. These challenges are tremendous, but governments should really
invest big and hurry these solutions if we want a chance to stop the
destruction of our atmosphere and mitigate the threat of peak oil.
2018 i better not see any power plants opened lol

ok, apparently the video is a year old, and i am wondering if there is been
any updates up or news. i want one of these kits, does anyone knowns where
i could get one,-
I am just wondering the purity of water needed for this . probably the
water need to be distilled , for which power is needed at the first place
How much is the efficiency of this panel?
