Precisely, I got Dow Z power in my garage, no problems.

Molybdenum disulfide is a common dry lubricant.

How worried are you about the sodium in table salt?

How about the highly flammable hydrogen in water?

Does anyone out there know how toxic and carcinogenic molybdenum is? Proliferated the environment with it is probably not a good idea.

We have plenty of surface area, don’t make the same mistake as this plonker “David MacKay FRS: Sustainable Energy – without the hot air” and completely forget to consider deep sea floating solar mats/arrays

So much of the nano scale end up left as concepts, I say you graphene some solar sails or possibly send like 1,000 pounds worth of material and a 3D printer covering a large piece of the moon for a base or power to beam back. If only they could make it 2 aerosol can sprayable layers. Even with the great material to efficiency ratio you’re looking at a lot of line to run the power itself as well as a lack of yet noted weathering and damage protection. I think we just need a big leap in the CZTS(15%+) efficiency and manufacturing process coupled with Spin cell cooling and concentrators. Or maybe, if someone would catch up and invent some plasma distribution engines, mercury base frequency resonance generators, or even a simple perpetutating generator.. Step 1 people, realize and document the known near infinite forces, Gravity, magnetism, static build, density distribution(floating/sinking, hot/cold,thermal expansion), atmospheric/oceanic pressure.. ect. They keep looking for answers in the same places, no surprise they find none. I would throw them a bone but it just doesn’t feel right. I see how those not wise enough to create the power misuse it, I won’t be that guy. If you’re reading this, give that near infinite force fuzion some thought, I’ll let you be that guy. I folded by Royal flush a bit ago thinking maybe this species when weighed by it’s actions is unfit to advance and spread, too many chimpStincts still. This might not occur to many but have you thought maybe we alrdy have the answers, like we do to cancers cure/causes, the energy/storage patents bought up oil/coal.. If you do choose to be ‘that guy’ you better show every media outlet at once in an unknown unscheduled surprise, or you’ll just end up in a cage or box before it happens.

“While that may not sound like much at first when compared to conventional solar cells, when you consider the resources, time, and materials that go into making conventional solar cells (as well as the space they take up and their weight) and compare that to a solar cell that is thousands of times lighter, uses considerably less material, and is lighter than tissue paper… the appeal of the technology becomes obvious. As of now, the two-layer solar cell design is about 1 nanometer thick — hundreds of thousands of times thinner than a conventional silicon solar cell.”

Create more surface area by folding. Light goes in, bounces around until it gets absorbed. However, this doesn’t work so well if the remaining energy is converted to heat instead of being reflected or transmitted through.

if the efficiency is just around 1-2%, you would use 20 times more surface area for sunlight interception, it would be a lot better to cultivate plants as source for food, and the remaining biomass as fuel for power plants.

Efficiency must be at least 5% to be really worthwhile, and the price per watt down to a few pennies per watt.

It’s hard for me to tell. But if these guys can work out manufacturing, it sounds promising.

Thanks for the post Zach. This is one of the biggest breakthroughs in PV Technology since the field of technology began. I read the origional orticle from the Lab and this will definitely make a huge difference in Solar Power Production.
