The stark hand

It is an artificial hand which is specially design for NASA. It moves easily and works like an electronic hand. The story behind the invention is like this:

A boy named Dave Vogt, when born has not his left hand by nature. A scientist Stark created an electronic hand for him and the hand has three knuckles (Which have a joint of a finger when the fist is closed). These knuckles can be bent according to the wish of the Vogt and he may catch the things easily. Interesting thing is that the Vogt may open all of his fingers freely by the moment of his shoulder that triggers a lever to extract. This artificial hand is really magical, because the Vogt may grip an egg with politeness and as well as drag a heavy chair.

When Vogt used this hand a ball is thrown towards him, he caught the ball with his artificial hand and certified that he is no more disabled and may do his work like a normal person.

A company named Edison Nation helps the inventors to develop their ideas selected the electronic hand for commercial production.

Dynamic eye sunglasses

Inventor: Chris Mullin

When a doctor Chris Mullin used to go to his laboratory 35 miles away from his house, the sunrays directly hit his eyes. The high penetrating rays cause headaches and give him trouble to see properly. Thus he decided to make a sunglass that may block the sunrays and protect his eyes. In 2002 he got a chance to work over his idea.

As lens material, he used a liquid crystal. The liquid crystal doesn’t give any obstruction to see through as a sunglass lens. Then he added a sensor on the bridge of the nose which finds limelight and gives a signal to a microcontroller attached nearby. The microcontroller reacts and gives instruction to the liquid-crystal lens to produce a 6 mm black square in front of the eyes to block the limelight. Surprisingly the square moves with the glass wearer to block the source of limelight at all the angles, but still gives a gap on the surroundings to let see properly.

Mullin is now developing an elastically plastic-based LCD, so that the product may be lighter and damage proof to sale in market on commercial scale.

The U.S Air Force has appreciated Mullin work and has funded in his project. Now he is working on developing a sunglass for soldiers & fighter pilots. Mullin claims that troops may go in high-noon sun onto the other place without any harm in illumination. The sight of the sunglass wearer will not be damaged. They may be able to see at the very moment after walking into sun. The scientist doctor making a plan to sell the idea to any of the big manufacturer of sunglass, so that they produce this Dynamic Eye shades commercially.

۩ Energy saving car head lights

Are you intended to save the energy of your car headlight, then wait for a little time? The big car company BMM is going to introduce laser headlights very soon. The company claims that these headlights will save energy in comparison to the normal headlights. To overcome the bad affects of the laser, which may be harmful for the passenger coming from the opposite sides, the lights produced by laser will be softened. The company is trying to pass the white light through fluorescent phosphor material in the headlight. The light which will come out from headlight will be bright and cool, giving no hazardous effect to the eyes of animals and human being coming in the range of this laser light. It will produce a huge intensity than LEO lights and safe a lot of energy. 

۩ Communicating cars

A large number of accidents occur when there is weak visibility and foggy situation takes place in the bad weather. The scientists of Bologna University, it a ly produced a modern device which will solve this problem and will save human life from collisions. This device will offer a communication to the approaching cars and deliver warning when ever any accident will take place. The warning system will be attached with an active sensor on dashboard; it will detect the accident when it takes place. Toyota is installing this system on the roads in Los Angeles. Surely this wireless device will save the human lives. The system will warm others about road blocks and slippery conditions.

۩ Magical camera

A camera with magical fiction is going to be launched in the last of this year by a company “Lytro” based in California. Often we faced a confusion when we photograph then came to know that the focus was not then came to know that the focus was not appropriate. We think the result of the snap will not be satisfied in camera technology has been made and you will never face this problem again. Now you may adjust the focus after taking the snap. Only you have to readjust the focus in the photo on the foreground, or background objects. You may adjust it in this way that all the objects come in a nice focus.

Ordinary cameras accumulates all the light rays to one point, but the new camera records the color, the power and its imaginary line position of the light position of the light rays differently, hence permitted the data to be done nicely by the software which mounted with strength in the camera.

۩ Fuel cell

In Georgian tech in USA scientist are trying to develop a new type of fuel cell which functions on coal gas. From coal gas is made and then the coal gas is used in the fuel cells. Scientists are claiming that by these fuel cells they may produce electricity with less expenditure. This electricity will be more efficient. The procedure of operating this fuel cell in like this the cell convert chemical energy into electrical energy which can be further used for different purposes. There are different kinds of fuel cells, for example hydrogen cells that produce electricity by oxidizing hydrogen with oxygen to make water from this process electrical energy generates. The electrical energy generated by these cells will be cheaper in comparison to the energy generated by turbines and thermal processes.

Portable watercraft

You will be able to know that a newly watercraft is introduced, which is portable and is running nowadays across the rivers & lakes having a speed of 25 mph and weighs 600 pounds.

When a boy Jason Woods was 19 years old living on his own, decided to buy an old ski boat. In his boat he drives the girls across the lake, near to his home in California. After few months he estimated that to drive a 16 foot boat is an expensive job. He was thinking about a boat that may carry in his car, but that dream didn’t come true. He was getting education at Napa’s New Technology High School and has a deep relationship with science and technology. In the meanwhile he get an idea that the carbon-fiber body board with a small engine power will have a tremendous speed. Its weight will be of 35 pounds only, so the persons who like adventure could carry it easily to the riverside.

It was Wood’s problem to find light weight parts. He search on different websites and discovered Germans are building 8 foot long & 20 hp mini yachts in these days. He also found that some companies are producing components for them. He purchased a small jet pump from a company in $500.
When he got the components he mounted the jet pump, and duct-taped the housing together. It took a jerk gave ugly voices, but it moved, and in this way Woods was able to build a new edition every year. His 4th edition put out 5 hp and run up to 15 mph. It also integrated with carbon fiber and handlebars.

Now the next model is under construction. A hybrid electric-propane four-stroke engine will be used in it and the boat will get the speed up to 25 mph. Woods estimated that on mass production basis the latest edition may be selling at $1,000.

Portable watercraft is a two-stroke gas engine drives a lightweight, high-powered jet pump, which throw out and creates a push, which deviate a little amount of water to cool down the engine.

The Body guard

The body guard is nothing but a crime-fighting armored glove invented by a cameraman, David Brown. It consists of a video camera & a stun gun to keep the outlaws away. Surely it can be said that Body Guard promise to save you life in odd situations. It runs on the high voltage stunner, a video camera, a laser pointer & flashlight. When you face any violation it protects you.

Brown think over it if a lion or any beast attacks on you suddenly, you have nothing to do. There should be a weapon which should work as your body guard. He wants to invent something.

As he worked over his idea, he came to know that his real market will be police force & military departments. He made a perfect glove in 48 hours from a medical arm pair, a stun gun and a fire-alarm button. After 7 years Brown became successful to complete his project. It looks and sounds horrible when electric current runs between its electrodes, which push back an attacker. As a last, it may be used to protect you.

This glove weighs only three pounds and is kept in a hard shell that extends across the forearm. A pull pin prepared the stunner and a button at the palm which activates it. Same buttons put in motion the laser pointer, video camera and flashlight. The Body Guard will be demonstrated at the U.S. Department of Justice’s very soon.

A great scientist claims that the solar energy will lead entirely in future. That will be a great need of this planet in the next coming 20 years. Now we could imagine our self the importance of this valuable energy, because we are now in disaster and facing energy crises. The reservoirs of gas, coal and petroleum is going to be empty. At last we have to search the substitute of it.

There is 10,000 times more sunlight than we need to meet 100 percent of our energy needs and the technology needed for collecting and storing it is about to emerge as the field of solar energy is going to advance.

Solar to compete in the next five years

At this time we have not any big planning for accumulating the solar and wind energy. But after seeing the statics of the future, we are serious and doing a valuable research and planning to store these energies. At present supply about 1 percent of the world’s energy needs, but advances in technology are about to expand with the introduction of nano-engineered materials for solar panel  making them more efficient, lighter and easier to install and take the demanding  benefits.

The researchers said that we are not that far away from a tipping point where energy from solar will be economically competitive with fossil fuels and   it could happen in the next 5 years.

In this connection other technologies which will be helpful are solar concentrators, made of huge mirrors that absorb very large amount of sunlight onto a small steam turbine. The energy can be stored by using nano-engineered fuel cells which will be available in the market soon.

You could create hydrogen or hydrogen-based fuels from the energy produced by solar panels and then use that to create for fuel cells.

Other troublesome challenges

Experts think that facing the energy challenge and the other troublesome challenges of the 21st century is simply important to our survival on this planet. Other challenges are:

1-         To clean water.

2-         Producing better medicines.

3-         Securing cyberspace.

4-         Improvement in practical reality.

The big and useful inventions gave us the green revolution that increased the production of food   as world population grew. The distribution of safe water and electricity, improved health generated an upgraded standard of living for everyone.

However, now the world faces some dark results of these advancements which are the threat of a security disaster, if nuclear and biological weapons fall into the wrong and fanatic hands.

More solutions to upcoming challenges

Other tech solutions for the new century’s big challenges include:

1-         Proper monitoring of nuclear weapons components to prevent them from getting in the hands of fanatic.

2-         Make an advance in rapid responses to possible bio-weapons attacks.

3-         Advances in genetic engineering to address the problem of drug-resistant viruses and bacteria, and to create personalized medicine.

4-         Purification of water to meet the demand of shortage of drinking healthy water.

The policy which will be run in the 21st century challenges plan, reveal a more enlightened understanding of role of science and technology in general. This idea is being developed in the context of a globalized world, even though the proposals have been developed in world.

Now OLEDs! Is coming

The flexible organic light emitting diodes (OLEDs) has been developed, which may lead to a television as thin as common magazine and so much flexible that it may be roll as a sheet of paper!

OLEDs have a thin layer of light producing organic molecules coated on a glass surface which gives out light when an electric supply is given to it. Scientists are trying to make the television screen of such materials. It will be interesting to know that the screens made of this material do not need back light and have a nice black/white contrast than liquid crystal. A very much wide television of this material will consume less electricity in comparison to the normal smaller televisions.

The screen made of OLEDs material can be printed onto flexible surface by using an ink jet printer. In this way the total cost will be reduced than the liquid crystal screens.

If OLEDS may be printed on textiles, they may lead to illuminated dresses which will give out different changing shades of light. The dresses will be supplied electrical power by small batteries that may be put in pockets. A big change may be expected in electronics and textile as well if the material is available in the market. OLEDs can enlighten electronic displays on carpets, TVs, textiles, and curtain. The ladies of future will surely shine and sparkle with the help of this material.

Mending a broken heart!

This has been detected that when anybody face a heart attack, he receives a heavy damage. The tissues of the affected area of the heart may die. It is also a fact that damage tissues can not be mending. However efforts are going on in this regard to use stem cells for repair of the damaged areas.

Recently the engineers of Brown University are working with scientists of India, have developed a patch made of carbon nanofibers to repair the damaged areas after heart attack. Surprisingly this patch produced by two countries scientists provides flexibility, so that it may expand and contract accordingly with the users’ heart.

When this patch is covered over the damaged tissues, the electrical signals may be transmitted through it, because it is a best conductor of electricity. It is seeded with heart cells which improved very fast on the patch, with the growth of neurons.

Quickly charged batteries

When a researcher observed that the electrically charged batteries take very much time, hence produce a problem. He solved this problem by refilling the batteries with the old charged battery fluid.

The fluid of discharged battery will be pumped out and newly charged fluid may be filled in no time. The use of these new batteries will be better in comparison to the heavy and expensive batteries. The new batteries will be lighter and cheaper, because a new liquid has been produced which is more affective than the old batteries.
