Comment (Most) nuclear waste isn't waste. (Score 3, Interesting) 138

Most of the "waste" from pressurized water reactors still has about 97% of its extractable energy left in it. It could fairly easily be reprocessed and reused in a PWR again, or used almost as-is in the future generation IV design fast neutron reactors.

The reason most used fuel is not reprocessed now, apart from the NIMBY complaints about the processing plants, is that "virgin" fuel is so cheap and abundant that the small extra cost is not deemed to be worth it.

Comment Re:What about long-term data integrity? (Score 2) 438

Correct me if I'm wrong, but don't SSD's have a point where they put on too many write's per bit?

Tech Reportchecked a bunch of SSDs for write durability and virtually all of them made it to 600 terabytes of data writes or better.

For an ordinary desktop user, write durability is not a problem. Now what about storage durability? With 3 bits per cell, how long before the data fades?

Only because most of the world lives under socialist regimes disguised as democracy, whether it's the dirty boot heels of dear leader kim, or the 'soft', stagnant, and effeminate, culture that's been grafted onto scandinavia.

As opposed to America where you're living under fascist regimes, state and federal, disguised as democracy.

Comment Artificial Clicker/ (Score 2) 136

I wonder if some sort of artificial pulse generator would be an improvement, rather than producing the clicks yourself.

You'd be guaranteed repeatability and might be able to shape the pulses in order to get a better result. Would differently formed clicks work better at different ranges or with different surfaces?

Comment Re:I do this with water temp. (Score 1) 136

I do something like this when I'm in the bathroom at work.

I can literally turn on a faucet here without touching the temperature of the water and the instant the water starts coming out warm I can hear the sound difference.

It's like the sound gets more "noisy" and less "linear" when it's hot water coming out. I can even tell as it's warming up since the pitch changes as well then holds steady at full-hot.

Anyone else do this? I'm starting to wonder if I'm alone here.

It's more likely a change in the physical dimensions of the pipe with temperature, rather than anything to do with the density of water. The pipe expands and its resonant frequency decreases.

Comment Re:People are the problem (Score 1) 82

Here in the Netherlands the problem is not in getting an AED on the site, but to find someone who can apply it. There are many people trained in using AED's and we here in the Netherlands possibly have the highest density of AED's, and although there is an elobrate system to call trained people to a person with a cardiac arrest, the problem is still in getting enough volunteers to join in. It is no use to have an AED within 200 meters from every house, if you don't have people who can apply them. AED's are not difficult to use, but in a case of emergencie, you need someone who can keep his/her head calm and follow the instructions.

The defibrillators I've seen give audio instructions plus have clear illustrations of how to use them. Unless the bystanders are REALLY stupid, it shouldn't be a problem

Right, that makes all the difference, because this is perfectly reasonable:

>We've discovered some counterfeit parts in your car.
-Oh, really? Well, I'm going to drive over to the dealership take that up with them.
>We've already handled the problem. We crushed your car into a cube.
-Uhhh...
>You have 15 seconds to move your cube.

As I understand it they're not bricking the device, they're bricking the OS's ability to use the device. As a result the customer will take it back to the person who supplied it. They're the ones who will be up for the cost.

Comment Re:Making stuff to make stuff (Score 2) 69

The solution to "can't manufacture stuff at home" is inventing cheaper manufacturing tools. I don't think we'll see replicators any time soon, but there's no reason why, for example, plumbers shouldn't be able to print plastic parts for dishwashers on-the-fly or in the shop rather than waiting for it to be delivered.

It will be better to order the part from a 3D copy shop which can afford better equipment and processes, and have sufficient volume to justify the expense.

Submission + - New Device Allows Fully Paralyzed Rats to Walk, and Human Trials Are Scheduled

An anonymous reader writes: A new technique pioneered by scientists working on project NEUWalk at the Swiss Federal Institute for Technology (EPFL) have figured out a way to reactivate the severed spinal cords of fully paralyzed rats, allowing them to walk again via remote control. Human trials are scheduled for next summer.
"We have complete control of the rat's hind legs," EPFL neuroscientist Grégoire Courtine said. "The rat has no voluntary control of its limbs, but the severed spinal cord can be reactivated and stimulated to perform natural walking. We can control in real-time how the rat moves forward and how high it lifts its legs."

SSRIs are also the preferred treatment for PMDD and in small doses, about 5% of the usual dose for depression.

In this application it also works almost immediately, no waiting 6 weeks for something to happen. The original article I saw speculated that it affects the amount of GABA in the brain.

. . . and my daily-use TV is a widescreen, high-definition tube . It works great! Cost me only $40! And at 126lb, no one is going to steal it. In fairness, it fits the built-in TV cabinet perfectly and at the time a similarly-sized LCD model was close to $600, so it made sense to go with the tube.

With the massive power savings you could get by replacing this old junker, you could pay for a new flat screen in a few years. However you'd have to make sure it had the inputs to talk to your old signal sources. I've seen some new TVs with HDMI inputs only.

With our luck, he'd probably sell the papers to Gina Rinehart. :-(

Comment Re:What kind of fish? (Score 1) 180

We have an overabundance of carp here. Normally eating carp seems to be an ethnic thing around here.Even then, only an older generation bothers with it. I would like the world to come and rid the Mid U.S. of carp, so I have included the only recipe I know for carp. 1 pressure cooker 1 5-lb. rock 1 carp Pressure cook the meat till it slips from the bone (about 2 hours) let cool, discard the fish and eat the rock.

I've never tried it, but I've heard they can be OK eating if prepared correctly. The recommendation I heard was to skin and fillet the fish, and age it in a freezer for some weeks. I think they used it in a stew after that.
