Comment Re:Water for Thought... (Score 1) 652

I always think its funny whenever this subject comes up on a forum like this, everyone thats not seen it done before calls everyone else an idiot.

When I was younger my dad showed me how to dowse with a coat hanger bent into an L shape. We were looking for the sewage line from the back of our house, because we'd just moved there and didn't know where the septic tanks were at. After walking around for a bit, I noticed the rod started lining up a certain way every time I walked past a certain spot. I showed my dad, he did the same thing, then we dug there and found the septic line.

I was maybe 10 years old, I had no knowlege of septic lines, the lay of the land, etc. All I was told was "hold this rod like this and walk around and you'll see it do something funny eventually." All we knew was that the line left the back of the house somewhere, and went towards a field, it could have been anywhere within about an acre of area.

I'm sure some of you don't believe it, but it works well enough I've seen DOT personel use it to find water lines under roads.

Agreed, but work is picking up most of the tab.

I like IT type stuff, but I realized I don't really enjoy programming which is what my undergrad mostly is.
I figured management might be a decent direction to head, since I know and understand the lingo, the technology, and could actually make some informed decisions.

75k or so in loans, and the year I went to college they jacked up the interest rate to 6.8%.

And to everyone saying its unsecured debt needs to actually look into their facts. Student Loans can not be bankrupt on, if I don't pay, the gubmint will dock my pay. Which actually is a better deal that paying the loans, the max they can dock is 15% per check, and my loans will be way more than that to actually pay.

The loans are government backed, they should be no interest.

Space Based Solar Power Within a Decade? 371

Nancy Atkinson writes "A new company, Space Energy, Inc., says they have developed what they call a 'rock-solid business platform' and they should be able to provide commercially available space based solar power within a decade. 'Although it's a very grandiose vision, it makes total sense,' Space Energy's Peter Sage told Universe Today. 'We're focused on the fact that this is an inevitable technology and someone is going to do it. Right now we're the best shot. We're also focused on the fact that, according to every scenario we've analyzed, the world needs space based solar power, and it needs it soon, as well as the up-scaling of just about every other source of renewable energy that we can get our hands on.'"

Hydrogen peroxide powered rocket packs fly for around 30 seconds, because they have a specific impulse of around 125, meaning that one pound of propellant can make 125 pound-seconds of thrust, meaning that it takes about two pounds of propellant for every second you are in the air. Mass ratios are low for anything strapped to a human, so the exponential nature of the rocket equation can be safely ignored.

A pretty hot (both literally and figuratively) bipropellant rocket could manage about twice the specific impulse, and you could carry somewhat heavier tanks, but two minutes of flight on a rocket pack is probably about the upper limit with conventional propellants.

However, an actual jet pack that used atmospheric oxygen could have an Isp ten times higher, allowing theoretical flights of fifteen minutes or so. Here, it really is a matter of technical development, since jet engines have thrust to weight ratios too low to make it practical. There is movement on this technical front, but it will still take a while.

Submission + - Gates Requests more H1-B Visas. (washingtonpost.com)

Beowulf_Boy writes: "Gates repeated his past calls for more H-1B visas, the controversial program used by technology and other companies to hire foreign workers for up to six years. More than half of the students in computer science programs at top U.S. universities are from other countries, but a limit on H-1Bs means many of those students can't stay in the U.S. after they graduate, Gates told the House of Representatives Science and Technology Committee."

Comment Re:no good case for perpetual copyright (Score 1) 547

copyright law exists to give incentive to artists to create socially and culturally significant works. perpetual copyright gives no such incentive, instead it provides incentive to create works intended to do nothing but generate profit.

And when something can generate profit, the tendancy is to take it to the extreme. I could see corporations copyrighting everything, even down to short sentences, in perpetuity. It would be a land grab. This has already happened with patents. You can't write a computer program anymore without using algorithms that someone has been issued a patent for, even though you didn't even know their patent existed.

Proposal to Implant RFID Chips in Immigrants 559

John3 writes "Some people are OK with voluntarily implanting themselves with RFID chips, but how about making RFID implantation mandatory for immigrant and guest workers? VeriChip Corporation chairman Scott Silverman has proposed implanting RFID chips to register workers as they cross the border. According to Silverman, 'We have talked to many people in Washington about using it...' Privacy advocates see this move by VeriChip as a way to introduce their product to Latin America after a lukewarm reception in North America. Would immigrant workers trade their privacy for the opportunity to work in the U.S.? If this type of tracking is enacted, how long before the government decides to start tracking others for various purposes (for example, pedophiles who are released from prison)?"
