And it had nothing to do with taking out a military nuisance for Israel.

Different groups had different ways to benefit off of a war in Iraq. The far right social conservatives are always hopeful that a mideast war can grease the skids for armagheddon. Halliburton made wonderful profits from supplying war related activities. Wars also serve as a conservative economic stimulus package.

But yeah, in order to settle an old family fight, we were going to go into Iraq to settle that score. Everything else was just gravy to some folks.

By my calculation, the ~1g of lithium in a common phone, if converted to tritium, could generate enough electricity to power a typical household for several years. So the cost of the lithium itself is negligible.

The costs involved with gathering and handling the tritium would be a different story.

What percentage efficiency of conversion are you using?

it still produces lots of radioactive waste.

Fusion produces less waste than fission, and it is shorter lived. But it doesn't help with the political problems. The Greenies and NIMBYs are going to oppose fusion just like they oppose fission.

As I've noted before, one doesn't need to be a Greenie, and one might understandably become a Nimby when they watch what happens to some of these completely safe reactors when things go wrong.

In short, I don't have a problem with Nuclear energy power generation. We can do this.

What I have a huge problem with is trusting that the humans in the loop are going to build something safe. The more dense the energy, the worse the problems when a human induced problem lets that genie out of the bottle.

What did we save money on? What corners did we cut to save money or meet the schedule? Who might we have paid off in order to pass a safety inspection?

I know people. I know energy. I know what happens when you put a shitload of energy in the hands of normal humans with their normal traits.

I know, right?

My first thought was "did they actually just explain to slashdotters what a fusion reactor is??"

I don't know how it was in the bad old days, but I'm pretty certain that a lot of present day Slashdotters need much of this stuff explained to them. Just looking at the conversations about Samsung phone batteries shows a remarkable lack of knowledge by many.

And really, that's okay. None of us were born knowing everything - even though I've been accused of being a "know-it-all". But if there is something I don't know, I have this excellent tool for learning that I'm typing on right now.

It is a very new thing to many readers because so little investment has been put in that development has taken decades.

Now let me get this straight. You are saying that Fusion generated power is a 100% certainty, and the only reason we aren't enjoying it right now in our homes is because not enough money has been put into it?

Well, I'm no dummy in such matters, but I'm not convinced that the bootstrap scheme is going to ever work. Not cynicism, or pessimism, but just looking at the positive feedback aspect of trying to sustain and contain fusion, and have leftover energy available to generate power.

The problem is not so much fusion, or fission, it's that there are other forms of energy too. And while fusion reactor designs have increased in cost three or four orders of magnitude in the last 50 years, in that same period PV has decreased three orders of magnitude.

So much this! And one interesting reason is that fusion/fission is relying on an old paradigm, that you have to generate a shitload of electricity at a centralized location, feed it through lossy lines and transformers, and it eventually arrives at your house. This involves a grid network of power generation and control, and all of the vulnerabilities thereof.

My guess is that legacy power needs will start to flatten out and possibly even decrease, as the renewables allow more and more people to go off-grid. If you build a house in an area that isn't in a development already served by grid power, solar is already cheaper by a mile than paying for the Utility company to run a line of poles to your place.

Yeah, I'm pissed off! Where's all the riches and oil we were supposed to get from Iraq after we invaded?

Not certain if you are poe-ing or not, since you seem to have an obsession with those left wingers you always rail about, but you have to forget the hearts and minds, and the WMD's, and the oil, and allowing some folks to believe that old Saddam was behind the twin tower attacks.

That's all so many different things that it gets pretty complicated.

Occam's razor cuts it down to the simplest and most credible reason. We were never going to get anything from the War in Iraq, or at least it didn't matter if we did. It was settling a Bush family score.

So a blanket of Lithium is added to the vessel, and the neutron hitting it, produce tritium and helium. That is where the "tritium is bred from lithium, so essentially free" from parent post come from.

I had no idea that lithium was free.

I guess that since you add yeast to a sugary concoction, and it pisses out alcohol, that ethanol is free too. Who knew?

I know you and Slashdot have a fetish for removable batteries but is dishonest to pain this as a sealed battery problem.

It has not one single solitary little bitty thing to do with a battery that is sealed in place, versus a removable battery. Where on earth did you ever in a million years get that idea that I was arguing that?

It has 100 percent, not a shadow of a doubt, irrefutable laws of physics, total to do with a battery compartment that is simply and 100 percent clearly - too small.

So unless the laws of physics make replaceable batteries somehow not expand when heated, not expand when charged, simply not expand - a replaceable battery will do exactly the same thing when placed in a compartment that is not capable of accomodating it's laws of physics bound expansion.

Don't imply that there' some vast conspiracy to keep better products away from the public. The consumers speak, and they want thinner phones with more battery life.

And they also want perpetual motion and to heat their entire house on 2 tea candles and a clay flower pot. You can't always get what you want.

You cant make "Want" alter the laws of physics. You can't just keep packing more power into smaller spaces and have no limits. You need to go back and learn just what chemistry is involved here. There are some real limits here. First of course is squeezing more power out of a battery. But as we do that, we can get to a point where a battery can be pretty dangerous. Li makes a nice powerful battery, but doesn't suffer fools gladly. Lithium isn't as nasty as Sodium or Potassium, but it's like Mr Bigglesworth - you don't want it to get angry with ya.

The electronics can be made less power hungry, there is some wiggle room there yet. But the amount of power needed to connect to a cell phone tower isn't changing all that much, and might actually increase as we end up with an overall noise floor increase with all of the wireless devices of all kinds in use.

You are a child, give your phone back to your mommy. You're not old enough or responsible enough now.

This is Slashdot, where somehow being a flaming asshole - how appropriate the term - makes a person a man of the highest character. I suspect - hope actually - that AC is just trolling, as it takes a special kind of stupid to actually want to hang on to a phone that has such a nasty design flaw.
