Battery "Runs" on Urine
Physicists in Singapore have developed a battery that can be powered by human urine. Aimed at disposable health-care kits for use in rural areas, we naturally couldn't pass up the opportunity to comment on such a product being used for those "emergency" phone calls when your conventional battery had died. Led by Dr Ki Bang Lee, a team at Singapore's Institute of Bioengineering and Nanotechnology developed a paper battery which is designed to be cheap to produce, and use urine as its power charge source.
Time to recharge the battery ?
Using 0.2 ml of urine, the team were able to generate a voltage of around 1.5 Volts with a corresponding maximum power of 1.5 mW. Battery performance can also be adjusted by using different construction materials.
"Our urine-activated battery would be integrated into biochip systems for healthcare diagnostic applications," says Lee. He envisions a world where people will easily be able to monitor their health at home, seeking medical attention only when necessary. "These fully-integrated biochip systems have a huge market potential," adds Lee.
The battery is made from a layer of paper that is soaked in copper chloride (CuCl) and then sandwiched between strips of magnesium and copper. The final product has dimensions of 6cm x 3cm, and a thickness of just 1 mm.
The research was published in the Institute of Physics' Journal of Micromechanics and Microengineering.

Faster Than Light
A pair of German physicists claim to have broken the speed of light - an achievement that would undermine our entire understanding of space and time.
According to Einstein's special theory of relativity, it would require an infinite amount of energy to propel an object at more than 186,000 miles per second.
However, Dr Gunter Nimtz and Dr Alfons Stahlhofen, of the University of Koblenz, say they may have breached a key tenet of that theory.
The pair say they have conducted an experiment in which microwave photons - energetic packets of light - travelled "instantaneously" between a pair of prisms that had been moved up to 3ft apart.
Being able to travel faster than the speed of light would lead to a wide variety of bizarre consequences.
For instance, an astronaut moving faster than it would theoretically arrive at a destination before leaving.
The scientists were investigating a phenomenon called quantum tunnelling, which allows sub-atomic particles to break apparently unbreakable laws.

Boomers & Beyond
According to today's regulators and bureaucrats, those of us who were kids in the 30's, 40's, 50's, 60's, 70's or even the early 80's, probably shouldn't have survived.
Our baby cribs were covered with bright colored lead-based paint.
We had no childproof lids or locks on medicine bottles, doors, or cabinets, and when we rode our bikes, we had no helmets. Not to mention the risks we took hitchhiking.
As children, we would ride in cars with no seat belts or air bags.
Riding in the back of a pickup truck on a warm day was always a special treat.
We drank water from the garden hose and not from a bottle. Horrors!
We ate cupcakes, bread and butter, and drank soda pop with sugar in it, but we were never overweight because we were always outside playing.
We shared one soft drink with four friends, from one bottle, and no one actually died from this.
We would spend hours building our go-carts out of scraps and then rode down the hill, only to find out we forgot the brakes. After running into the bushes a few times, we learned to solve the problem.
We would leave home in the morning and play all day, as long as we were back when the street lights came on. No one was able to reach us all day. No cell phones. Unthinkable!
We did not have Playstations, Nintendo 64, X-Boxes, no video games at all, no 99 channels on cable, video tape movies, surround sound, personal cell phones, personal computers, or Internet chat rooms.
We had friends! We went outside and found them.
We played dodge ball, and sometimes, the ball would really hurt.
We fell out of trees, got cut and broke bones and teeth, and there were no lawsuits from these accidents. They were accidents. No one was to blame but us. Remember accidents?
We had fights and punched each other and got black and blue and learned to get over it.
We made up games with sticks and tennis balls and, although we were told it would happen, we did not put out any eyes.
We rode bikes or walked to a friend's home and knocked on the door, or rang the bell or just walked in and talked to them.
Little League had tryouts and not everyone made the team. Those who didn't had to learn to deal with disappointment.
Some students weren't as smart as others, so they failed a grade and were held back to repeat the same grade. Horrors! Tests were not adjusted for any reason.
Our actions were our own. Consequences were expected.
The idea of parents bailing us out if we got in trouble in school or broke a law was unheard of. They actually sided with the school or the law. Imagine that!
This generation has produced some of the best risk-takers, problem solvers, and inventors, ever. We had freedom, failure, success, and responsibility--- and we learned how to deal with it.
The Monk
Joseph Aigner was a fairly well-known portrait painter in 19th century Austria who, apparently, was quite an unhappy fellow: he several times attempted suicide. His first attempt was at the young age of 18 when he tried to hang himself, but was interrupted by the mysterious appearance of a Capuchin monk. At age 22 he again tried to hang himself, but was again saved from the act by the very same monk. Eight years later, his death was ordained by others who sentenced him to the gallows for his political activities. Once again, his life was saved by the intervention of the same monk. At age 68, Aiger finally succeeded in suicide, a pistol doing the trick. His funeral ceremony was conducted by the same Capuchin monk - a man whose name Aiger never even knew.
