Making good on a promise from December, start-up battery maker Boston-Power announced today that its almost-too-good-to-be-true Sonata lithium-ion batteries are now for sale, as upgrades for HP laptops. Boston-Power's claims are impressive: A Sonata cell promises to charge to 40 percent capacity in just 10 minutes (say, the airport wait time from when they start boarding first class until they get to your steerage section). And they reach 80 percent capacity in just 30 minutes.
This reads more like an advertisement than an article from popular science.Wheres the science.I like HP personally they have very good customer service,and My hp pavilion has been a pleasure to own.
Standard drills will barely make a chip in concrete or brick. That’s why contractors drilling holes in a home’s foundation use rotary hammer drills like this new Hitachi DH50MRY. In addition to the standard spinning bit, it slams a weight—the hammer—forward to create a sort of jackhammer effect to crush masonry as it drills. But all that pounding beats the heck out of your hands and arms. The Hitachi is one of the first to integrate a counterweight to absorb recoil. The result is a safer and easier-to-control drill that’s still concrete’s worst nightmare.
I was actually expecting some kind of massive industrial drill press or something.Slightly let down yeah.

I've used the hilti many times,and I never saw a six inch bit,but I bet they make them.Would be very expensive.usually people grab a self feeding drill that looks like a coring tool when the holes get that size.there are companies out there that do that and not much else.I have used a 3 inch diam. bit myself,and have seen 4 foot long bits.If your not a man when you pick up one of these monsters you will be by the end of the day.It is amazing though what you can put a hole through.
Built for tasks like lifting 55-ton generators to the top of 300-foot windmills, the Liebherr 11200-9.1 might just be the world’s most monstrous truck. The 108-ton 18-wheeler doubles in weight when the boom—-which with extensions can reach 47 stories—-is attached. Fully assembled, it can lift up to 2.6 million pounds. Without the boom, it can drive on public roads, so getting it to a job site requires five fewer trucks than it would take to haul in and assemble an equally large fixed crane. It’s also far easier to move from place to place once it’s on-site.
I really doubt it will lift 2.6 million pounds.I just dont think you could get a strap around it for one thing.ha ha
During the early 1930s, Duke University went against the grain and opened a parapsychology lab. J.B. Rhine, who actually coined the term parapsychology, along with his colleagues sought to uncover the truth about various phenomena using scientific methods. In Unbelievable, author Stacy Horn chronicles the decades of research done in the lab. PopSci.com's Catherine Schwanke recently spoke with Horn by phone to discuss her new book, and the unbelievable. Plus: Got a question for Stacy Horn? Ask away! We've devoted a forum to your queries here. Ms. Horn will answer as many of your questions as possible, also in the forum, during the week of March 22-27. Feeling lucky? Leave a comment (any comment) below. Ten commenters, randomly chosen on March 31st, will win a free copy of Unbelievable
The problem with this science is the reproduction of effects.I have read several books on the subject,and they all point in that direction.That these effects can not be proven to exist because they are not repeatable,and predictable.This article seems to focus on ghost,and mentions a couple other extra sensory perceptions,but the world of the unexplained is vast,and overwhelming to say the least.I personaly have had many precognitive dreams,and know that these are real.So for me its not a question of is it possible,but of how much of what I hear is true,or not.Of course there is no posible way to know this anymore than there is a way to prove my experiences really happened to you.It would be interesting to hear any actual findings issued by the established authority on the subject.The problem I have with their methods is,it is basicaly statistics,and they say an effect is proven,or not because it sits outside of the curve that would be produced by using random data.My trouble is difining random.Is there really such a thing.Because it seems to me everything is caused,or effected by something else in one way or the other plus you are in most cases dealing with people,so is that really random if there is no other effect present.Anyway it would be interesting to hear of any other scientific methods out there.Perhaps like the studies done on the visible energy fields of all living things(even plants).
The ultimate in green living is almost here. Think bus shelters, street lamps, and even houses -- all grown from trees. The process of shaping living trees to create objects, referred to as arborsculpture and pooktre, is well known among hobbyists (a simple Web search shows plenty of results for the art form). Now, researchers at Israel's Tel Aviv University are teaming up with eco-living company Plantware to create commercial structures on a larger scale.
Well an obvious question for me is what happens when your house is grown,does it just stop there or keep on growing.Will I have to chainsaw my way out of the breakfast nook some day.It seems also that you would be hard pressed to grow something large enough to live in,in your life time.The only thing I can think of is the giant sequoya trees(however its spelled you know what I mean),and they take a few years to get that big I'm sure.It seems if you could produce a wood bearing plant that could grow fast enough that a person could order one,and in a reasonable amount of time move in,that it would many times easier to design it to grow in a nice square shape so we can quickly produce the neccessary lumber needed by our craftsmen to build a house when needed.If you want to get all evironmental about it just make the thing use a large percentage of carbon in its life cycle,and store it in the wood.Better yet make a tree that secretes two by fours out its back side every couple of minutes.
Today’s most ambitious scientific instruments are modern-day cathedrals in their size and complexity, if not in their purpose—these are, after all, structures built to shatter worldviews, not to reinforce them. And the grandest of all, pictured on these pages and fired into action today, will take us on a journey to one of the least-accessible places imaginable: the realm of quantum particles, less than a billionth the size of a single atom.
I'm curious why the writer was so worried about justification for the money spent.Which by the way didn't just vanish into some mysterious other dimension.It was paid to workers,and manufactuers ect.It would have been nice to have heard more about this machine,and how all its parts work together.Of course he does talk about some of the good things the machine may bring about.We don't know what this machines value realy is,but It does give us posibilities that would have been uncomprehendable to the giants from are past that we owe our feeble understandings of the universe to.It may only add one small new fact to our meager stock of knowledge,but it may be a new understanding of spacetime for example.What value would you place on unlimited power,or the ability to not only leave our little dirt ball(earth),but to reach for the very stars we wish to understand.Oh on a earlier comment mass,and energy are the same things in a different form so the big bang could be seen as enough energy to create all the mass in the universe.so you don't have to try to imagine everything there is coming from a singularity,but it is interesting to consider all this energy(a massive amount odviously)has no mass,and perhaps no other dimensional quantities as we think of them(tall,wide,long,and maybe even time),but if you look at the amount of energy released from the small amount of mass in an atomic bomb its pretty much impossible to fathom the energy that would be created by converting all known mass back into energy.Anyway back to the collider,we don't know what value this thing has for sure,but the possibillities,well they are unlimitted.
Researchers at the Lawrence Livermore National Laboratory in California successfully converted sound waves to light radiation by reversing a process that transforms electricity to sound, which is commonly used in cell phones. This is the first time that sound has been converted to light. The findings, which were published this week in Nature Physics, could improve how computer chips, LEDs, and transistors are made, and also have applications in ultrafast materials science and terahertz radiation (T-ray) generation. The research team initially predicted that the conversion was possible around a year ago, using computer modeling, and has been trying to confirm it in the lab ever since.
This is a natural process where crystal can convert a mechanical force into an electrical impulse.in this case the mechanical force is created by sound which is a wave that changes intensity or force as a function of the sine.As in a sine wave just like light.Is this really a conversion from sound to light,or just a way to mechanicaly manipulate the crystal at these frequencies,and sine varying quantities?
