Fuel Cells Savings

Fuel Cells Savings
We've gone on the record saying fuel cells are at least 20 years away. But when will that make a big difference in our use of gasoline? A long, long time:

"The potential for hydrogen fuel cells having an impact that you'd notice is a long way away," says John Heywood, professor of mechanical engineering at MIT. The estimates assume that competitive fuel cell vehicles will be available within 15 years, an achievement that will require improvements, for example, in hydrogen storage and production and fuel-cell costs. But even if and when fuel-cell vehicles come with the price and performance that consumers want, it will still take decades more before such new vehicles work their way into widespread use.

MIT is talking 60 years in regards to gasoline usage and nasty emissions before hydrogen makes a big enough difference for any of us to benefit from. So what to do?

Use less of the stuff. But MIT knows that's not the American way:

Heywood admits these ideas might not be rapidly adopted: "It's not American to conserve. We seem to have drifted into that attitude. Our culture doesn't bring us up to think about conserving. It brings us up to think about consuming".

We are totally diggin' the new subcompacts from the big 3 of Japan and are honestly hoping our big 2.5 from home announce competitors to those vehicles rather than announcing more of the same.........

How To Attach Two Phone Wires To Make One

How To Attach Two Phone Wires To Make One
If you need a long phone cable in a pinch two shorter cables can be quickly spliced together until you can buy a real cable.

Steps.

Cut the wires. Cut one plastic connecter (plug) off of each wire, you should used dykes or wire cutters, but if you don't have those a knife or scissors will do. It is important that you cut opposite sides off otherwise the you stand a 50/50 chance of screwing up step three. If you look at the connectors with the hook down you should see four wires in this order Black, Red, Green, Yellow from left to right and the other connector will have them in reverse order. Cut the connector with the wires in BRGY off the first wire then the connector with the YGRB off the second wire. (See diagram).

Viewed with hooks facing down on all connectors. Cut the connector with the wires in BRGY off the first wire then the connector with the YGRB off the second wire.

Strip the insulation back. Using a sharp knife or razor blade remove an inch of the outer plastic covering from the end you just cut. This should reveal four wires, strip 1/2" off of each of these individual wires.

Property match the wires. If you cut the wires properly you should be able to match up the colors if you didn't just make sure the wire that is on the far left of one connector is on the far right on the other side of the wire. (See diagram).........

The Singing Keyboard Prank

The Singing Keyboard Prank
This year I decided to go all out for April Fools and do something that could be duplicated across multiple computers without permanent damage - and so the singing keyboard hack was born.

Concept.

Take the musical element from a musical greeting card and connect it to the caps lock LED on the user's keyboard. Each time the victim presses caps lock the music plays (and quite loud too). This is a great sleeping prank.It might be found on the first day, or weeks from implementation. It's the perfect prank.

Why Caps?

True, most people don't use caps lock very often, if ever, but unfortunately not many other keys are linked to an LED. Also most keys are only pressed momentarily, which would require a solid-state bounceless switch; which I had trouble getting to work. The num lock LED turns on and off several times during boot time, so that's out and only leaves the caps lock as a viable solution.

Disclaimer.

If you decide to do this prank understand that it could be a career-limiting move if you do it to your boss and/or somebody without a sense of humor. I would also recommend to first experiment with a dummy keyboard that you don't mind destroying.

I will not be held responsible for your problems. ;o).

Setup.........

TabletKiosk eo V7110 arrives in the US

TabletKiosk eo V7110 arrives in the US
Sure, it might be $900 bucks, but the TabletKiosk eo V7110 is not only the first UMPC to arrive in the States, but it happens to be the cheapest UMPC announced so far. It just started shipping today, but lucky reader Tomi B. got his hands on one already and snapped some unpacking pics to share.

Thanks Tomi! We can't say it looks quite as good as the marketing pics, but we're liking the white casing and we'll reserve any other judgements until people start snapping in the battery and firing this thing up. Click on for a couple more shots.........

Touchless Trashcan

Touchless Trashcan
Would you ever watch an old TV without a remote control again?

Welcome to the 21st Century! Once you tried the Touchless Trashcan, you will never go back to the traditional or step-on trash can again. After all, it's your most use appliance everyday, make it easier!.

Touchless TrashcanTM is a patented new product widely recognized in Europe. And it has just been introduced to North America. Sold thousands on infomercial, QVC and HSN home shopping channels. It won the 2002 Invention Show - New Household Product Award.

It is a 100% hands-free operated, wireless, lidded waste disposal system. The built-in Artificial Intelligent (AI) Smart-Chip knows when you need to open trash can, and do all the openings and closings for you without touching or step-on anything.

How it works?

The Touchless Trashcan uses patented invisible harmless infrared technology. Place hand or debris about 6 inches away from the infrared sensor near the lid. It will open instantly when you approach and will close automatically in 3-second after debris has been released and hand moves away. Lid will remain open if debris or hand is within 6 inches range of the infrared sensor. There are 2 buttons on the front to open and close the lid manually and an on/off switch on the back of the trashcan.........

Embryos In 3-D

Embryos In 3-D
Utah and Texas scientists combined miniature medical Computerized axial tomography scans with high-tech computer methods to produce detailed three-dimensional images of mouse embryos - an efficient new method to test the safety of medicines and learn how mutant genes cause birth defects or cancer.

"Our method provides a fast, high-quality and inexpensive way to visually explore the 3-D internal structure of mouse embryos so researchers can more easily and quickly see the effects of a genetic defect or chemical damage," says Chris Johnson, a distinguished professor of computer science at the University of Utah.

A study reporting development of the new method - known as "microCT-based virtual histology" - was published recently in PLoS Genetics, an online journal of the Public Library of Science.

The study was led by Charles Keller, a pediatric cancer specialist who formerly worked as a postdoctoral fellow in the laboratory of University of Utah geneticist Mario Capecchi. Keller now is an assistant professor at the Children's Cancer Research Institute at the University of Texas Health Science Center in San Antonio.

University of Utah co-authors of the study are Johnson - who directs the university's Scientific Computing and Imaging Institute - Capecchi, medical student Mark S. Hansen and several members of Johnson's institute: computer science undergraduate Thomas Johnson III, research assistant Lindsey Healey and former associate director Greg M. Jones, who now is state science advisor to Utah Gov. Jon Huntsman Jr.........

Babybot Takes First Steps

Babybot Takes First Steps
BabyBot, a robot modelled on the torso of a two year-old child, is helping scientists take the first, tottering steps towards understanding human perception, and could lead to the development of machines that can perceive and interact with their environment.

The scientists used BabyBot to test a model of the human sense of 'presence', a combination of senses like sight, hearing and touch. The work could have enormous applications in robotics, artificial intelligence (AI) and machine perception. The research is being funded under the European Commission's FET (Future and Emerging Technologies) initiative of the IST programme, as part of the ADAPT project.

"Our sense of presence is essentially our consciousness," says Giorgio Metta, Assistant Professor at the Laboratory for Integrated Advanced Robotics at Italy's Genoa University and ADAPT project coordinator.

Imagine a glorious day lying on a beach, drinking a pina colada, or any powerful, pleasurable memory. A series of specific sensory inputs are essential to the memory.

In the human mind all these sensations combine powerfully to create the total experience. It profoundly influences our future expectations, and each time we go to a beach we add to the store of contexts, situations and conditions. It is the combination of all these inputs and their cumulative power that the ADAPT scientists sought to explore.........

XMM-Newton Provides Impressive Sky Survey

XMM-Newton Provides Impressive Sky Survey
For the past four years, while ESA's XMM-Newton X-ray observatory has been slewing between different targets ready for the next observation, it has kept its cameras open and used this spare time to quietly look at the heavens. The result is a 'free-of-charge' mission spin-off - a survey that has now covered an impressive 25 percent of the sky.

The rapid slewing of the satellite across the sky means that a star or a galaxy passes in the field of view of the telescope for ten seconds only. However, the great collecting area of the XMM-Newton mirrors, coupled with the efficiency of its image sensors, is allowing thousands of sources to be detected.

Furthermore, XMM-Newton can pinpoint the position of X-rays coming from the sky with a resolution far superior to that available for most prior all-sky surveys. This is sufficient to allow the source of these X-rays to be found in a number of cases.

By comparing XMM-Newton survey's data with those obtained over a decade ago by the international ROSAT mission, which also performed an all-sky survey, researchers can now check the long-term stability, or the evolution, of about two thousand objects in the sky.

An initial look shows that some sources have changed their brightness level by an incredible amount. The most extreme of these are variable stars and more surprisingly galaxies, whose unusual volatility may be due to large quantities of matter being consumed by an otherwise dormant central black hole.........
