Nanodots and Seawater




TECHNO THRILLS                               




Filler-Up!


A battery that uses nanotechnology to charge your smartphone in 30 seconds may sound like something out of a sci-fi movie but an Israeli startup claims to have created just that.

It relies on bio-organic nanodots, tiny conductive crystals that help enable rapid charging. I don't know nothin' about machinery, but I wonder if this technology could somehow be applied to electric car batteries?  I mean, I'm no eco freak, but wow, a breakthrough like this would pretty much relegate the  middle east sand oil industry to buggy whip status.  Just a pipe dream though.  But who care?  The U.S. Navy is making jet fuel out of seawater!  USA UAS USA! 


Railguns aren't the only thing the U.S. Navy is bragging about this week. Scientists at the Naval Research Laboratory in Washington, D.C. announced they have successfully turned seawater into fuel.

When your car runs out of gas, you find a gas station and fill it up. For ships and planes, however, there aren't any stations out in the middle of the ocean. Instead, the Navy's vessels are refueled by oil tankers that come to them.

All of that will change in the future. By extracting carbon dioxide and hydrogen gas simultaneously from seawater, and then using a catalytic converter, scientists created fuel that looks and smells pretty much the same as regular ol' petroleum-based fuel.

The advantages of seawater-based fuel is twofold. First, the ships don't need to be redesigned in order to use the new seawater-based fuel since it's basically the same. Second, the ability to create fuel from all that water around aircraft carriers means less dependence on oil. The U.S. Navy envisions ships will be able to create their own fuel for themselves and for planes. So long oil tankers!

"Game-changing" as the breakthrough is, the U.S. Navy says ships that generate their own fuel from seawater aren't going to start sailing the seas anytime soon — they're at least ten years away. For now, the U.S. Navy's scientists are focusing on how to produce larger quantities of seawater-based fuel.

I wonder if Obama has given all of this technology to China yet?

Sea water vs. fuel? I have no doubts it can be done. My question is: How many Watts in per BTU out? On what scale? If it works, I think it would be limited to a nuclear powered ship, for use as aviation fuel.

Rail guns have been tested for decades. Not a big deal.

industrial hemp would completely destroy the oil industry almost overnight. so they made it illegal. they'll make electricity illegal if they have to. or make it unreliable somehow.

But there is a seawater shortage already! We cannot allow the USN to deplete our seawater reserves!

Don't worry; government will tax the hell out of it, and erect a barrier wall around the country to limit free access to sea water.

On the idea of these new batteries and electric cars: There
are a few problems here. Even if rapid charging is possible,
it will not work so long as we are using coal and natural gas
to generate the electricity.

It will result in a huge demand to increase the supply of
electricity, and electrical infrastructure. So long as the tree-
huggers will resist ANY type of power generation, this would
be entirely academic.

If the environmental left actually cared about the planet, they
would be all for nuclear power!

Is this what Barky was talking about when he said that his election meant that "the seas would cease to rise"?
Naah.

Anonymous,

It's only a question of energy. If you have enough energy, synthetic fuels are easy. A small nuclear plant can easily provide fuel for an aircraft carriers fleet.

Given enough cheap energy, resources abound.
