Thanks for the explanation.

I agree with you about the need for distributed power sources. But maybe there would still be situations where such a large amount of power would make sense if it was feasible and economical. Aluminum smelters already have their own GW power stations.

The financing issues for fission reactors may be related to the problems of long term storage of large amounts of waste. Unfortunately too many people may simply have the idea that "nuclear" means bad.

The real irony is how much money is spent on research into better ways to kill other people, and in actually doing so.

I do not understand the compulsion of people to endlessly and vehemently complain about the impossibility of perfectly sound concepts

Maybe try talking to the guy who says the following

Tokamak fusion is not, and will never produce economical power, even if it works

(emphasis mine) Maybe he can explain it to you.

Maybe you'll claim that it's not a sound concept, but there are quite a few experimental reactors that exist now.

I like SABRE, I also like Tokamak. Will either one actually succeed? I don't know, but you seem to be making the same sort of complaints that you talk about.

You're right. Water has a high heat of vaporization. The amount of energy required to vaporize a given amount of water is close to 5 times the amount of energy that would be required to heat that same amount of water from 0 C to 100 C.

So think of it as being a bit like taking the amount of water in the condensate, heating that to 500 C* and adding it to your beer. (* heating to that temperature without vaporizing)

It does seem a bit funny to emphasize moving "individual atoms" when they are really molecules. I think manipulating a two element molecule is just as impressive, but why not just say that so as to be correct?

The first thing that struck me while watching the video is that many of the "atoms" appear to be a pair of dots, although one is much less prominent. I would have expected an atom to appear as a single dot. They say that you can only see the oxygen atoms, that the carbon atoms are "off screen". I wonder if the second dot is actually the carbon atom partially on screen.

Just think about it, it makes sense.

I'm pretty sure western spy agencies have access to much better tools than Google Earth. You probably could claim that Google Earth is a produce of tools for western spy agencies. That doesn't mean that there's anything wrong with Google Earth.

... we will put a kind of information on our website that would take people of the world towards reality

Wouldn't it be much simpler to just point out what part of Google Earth does not represent reality?

+ - New catalyst allows cheaper hydrogen production

Submitted by CanadianRealist
CanadianRealist writes "Electrolysis of water to produce hydrogen is very inefficient without the use of a catalyst. Unfortunately catalysts are currently made of crystals containing rare, expensive toxic metals such as ruthenium and iridium. Two chemists from the University of Calgary have invented a process to make a catalyst using relatively non-toxic metal compounds such as iron oxide, for 1/1000 the cost of currently used catalysts.

It is suggested this would make it more feasible to use electrolysis of water to create hydrogen as a method of storing energy from variable green power sources such as wind and solar."

MarkWhittington writes "Included in President Obama's 2014 budget request will be a $100 million line item for NASA for a mission to capture and bring an asteroid to a high orbit around the moon where it will be explored by asteroinauts. Whether the $2.6 billion mission is a replacement or a supplement to the president's planned human mission to an asteroid is unclear. The proposal was first developed by the Keck Institite in April, 2012 and has achieved new impetus due to the meteor incident over Russia and new fears of killer asteroids."

Submitted by Anonymous Coward
An anonymous reader writes "Two designers from Toronto have been working on developing an affordable desktop 3D scanner. Offered through their Indiegogo campaign, it currently retails for $399, and is being offered for a limited quantity at $349. The specs are below:

Features at a glance:

- High resolution scan created with a high definition camera and dual lasers.
- All scanners are fully assembled and tested prior to shipping. There are no kits here.
- Easy folding design makes storage or transport simple.
- Quick scans. Multiple quality settings can be chosen but an average scan is 3 minutes.
- Looks awesome. Shoots lasers.
- Scan objects up to 190mm x 190mm x 250mm (7.5" diamter x 9.75" height)

If sugar beets were a viable fuel source someone would be doing it already.

From the summary: "Europe already has more than a dozen such plants". So maybe it is viable.

In any case your argument suggests that anything that isn't currently being done isn't viable. So any sort of progress is never possible.

Samsung Want To Sell Liquavista To Amazon 18

Posted by Soulskill
from the amazon-to-take-over-more-of-the-world dept.
Nate the greatest writes "Bloomberg is reporting early this morning that Liquavista, Samsung's cutting edge electrowetting screen tech research firm, is up for sale. Details are still thin but Bloomberg's unnamed source indicates Amazon is looking to buy Liquavista for somewhere under $100 million. This rumor confirms earlier reports that Amazon had launched a new holding company in the Netherlands and was going to use it to buy Liquavista. There have also been rumors circulating screen tech conferences for the past 5 or 6 months that Samsung was interested in selling the company. No one in the industry really understands why Samsung would want to do that, but I think the latest demo video from Liquavista explains it. This screen tech simply isn't as good as current LCD or OLED screens, and Samsung might be looking to cut their losses."

Here's an interesting bit from the linked article:

Virtually everyone says that I should have plugged in the car overnight in Connecticut, particularly given the cold temperature.

Then that same paragraph finishes with:

... cannot realistically expect all 20,000 buyers a year (the Model S sales goal) to be electric-car acolytes who will plug in at every Walmart stop.

So the reviewer made an overnight stop at a Walmart in Connecticut? I'd say that if you have to exaggerate to that extreme to make you point, then you're pretty much admitting that you don't have point to make.

The reviewer's own argument (at least this part) makes me believe Tesla is right.
