I affixed high-efficiency monocrystalline silicon PV cells to the aluminum cans and used pizza boxes strewn about in my yard and now my trash is generating electricity! Electricity from trash, wow!
The next big thing will no doubt be the Petatron Plasma Wakefield Accelerator. Where will it be built? Who knows, but it probably be small enough to fit inside a large industrial building. Or likely an adjunct to an existing collider.
Not so fast. The orientation of the vehicle depends on the orientation of the magnetic field and the orientation of the magnetic field is easy to set within the track. Can't say this is a fake or not but I think the physics is sound.
I tried this and was able to get my XBox 360 to talk to my Ubuntu computer. The XBox could see my media directory on Ubuntu (over the network) just fine. While it would play a.wmv quite well, it would not play most.avi's..mks files are popular now but nope..mp4? Sorry. I figured if I wanted to support this type of environment I'd have to be ambitious and convert my media library to.wmv which isn't worth the time and frustration. I'd still like to set up a media center but I think it's going to be some sort of Linux solution.
You have the option of increasing the number of sites or not. If not, then put a bunch of small standalone reactors together. It probably makes sense from an efficiency and reliability standpoint to have many sites rather than one big one. Although security for many smaller sites seems more problematic.
Trolling? OK I'll bite. "So you don't think it has anything to do with the fact that the energy density of gasoline is 12,200 Wh/kg while lithium ion batteries have an energy density of 439 Wh/kg plus a limited charge cycle of ~1000?"
I've long thought that the ideal way to further develop nuclear energy is to build microreactors in a research mode then over time refine the design into a production reactor, then deploy the microreactors, amassing as many as you need for a given application. The size of each would be shipping container size. A design goal would be to standardize the design so that the microreactors could be serviced/refurbished robotically. On the site the reactors would be located below grade and each microreactor should be capable of producing about 5-10 Megawatts of electricity.
This approach would allow the details of the use of thorium to be worked out without investing in huge reactors. Also, no scaling of the design is required, just build more reactors.
I wonder what the admission charge will be? If they get 1000 visitors each paying $1.5M apiece they'd be able to break even. Likewise if they get 10,000 visitors paying $150,000 each.

I watched the vid but I wasn't convinced that you could pull something through the water like a kite tail and have it pick up significant amount of oil. I used to mow a couple of acres of grass every week using a riding lawn mower. The width of the cutting deck was 46" but it still took a fair amount of time to cover the area. In all the pictures, the absorber looked really small in diameter. One of these trying to soak up a square mile of oil would look pretty ineffectual especially as viewed from above it would just be carving a thin line that would close back up after a few minutes. I would think you'd have to have many thousands of them working in concert to put a dent in any but the tiniest spills.

Well, I guess if you are somehow able to set up a magnetic field that circles the craft then charged particles heading towards the craft could possibly be bent around the craft without making contact. This is due to a magnetic field causing Lorentz forces on the incoming particles. However, this only takes care of particles that are heading right for the craft, i.e. normal to the body. Particles moving parallel to the body might well be snagged and sucked into the body due to the same Lorentz forces.
The other issue is generating magnetic fields is non-trivial and usually requires heavy equipment, i.e. permanent magnets, coils and iron cores. Any workarounds on this?
I think gamma rays might still be a significant problem.
I've been out of school for quite a while but have kindled an interest in physics. I find that more and more there are Youtube demonstrations and lectures that are worthwhile. Also labs and hands-on science work is invaluable so I'd check out instructables.com because this not only can provide unique science opportunities, it also helps people in gaining engineering skills.

Hire the countries best teachers and graphics artists, and have them create the absolute highest quality educational videos money can buy. Then, put them in the public domain.
I think that's a pretty good idea, in fact it's an idea I'd been thinking about as well. I think it would be helpful to also include a searchable FAQ along with each lecture so that students can get clarifications. Also everybody learns in different ways. What might be clear to one student will confuse another so having multiple approaches to the same subjects allowing a student to pick and choose would be outstanding. Recently on Youtube I watched a one-hour lecture on electricity and magnetism from Berkeley. The instructor was good, i.e. he liked the subject and was good at teaching it. I found that it helped clarify my understanding.
I think I went from Lycos hosted at CMU (and later hosted on their own servers) to Alta Vista to Excite to Google. (I was bummed when DejaNews got bought out by Google because even then I sensed that was the beginning of the end of usenet.)
I think Bing will be good for the end-user because it will keep Google honest however I don't think Bing will exceed/succeed Google.
I bet awk would be a good first language. You can do interesting things almost immediately with it and when you delve deeper you start getting the rudiments of C syntax which leads to a good many of other languages. Plus it gets you thinking about regular expressions. Then you can go on to C++, Java or ruby for OOP.

So rather than using the tools of evolution, the students of Tennessee would learn to pray to god for a new vaccine?

Can we go back to the old corn now?

ZOMG! I see your point completely. My humble appologies.

LOL -- the "flavor of vinyl" basically means distortion and inaccuracy, doesn't it?
Huh? You say that like it's a bad thing.

BTW, this discovery has nothing whatever to do with dark matter.

I vote for Epsilon to handle this one.
they nabbed him as he was getting off the Jetway? Maybe just for grins an agent holding up a sign saying "Prison."
