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.

Mouse nose

Sensitive nose of a mouse protecting human being from executioner is necessary. Although we invented such scanners that detect the explosive, but still the planes blast in the air with a bloom. Big buildings like twin towers are shattering into small pieces. For detecting explosive we trained dogs, and they are fulfilling their duties nicely due to their sensitive smell power.

A new research has been made in this field that mouse have more sensitive nose rather than a dog. If a dog has 756 olfactory receptor genes, where as the mouse have 1,120 such genes. Then we could conclude our self that mice are very much sensitive in smelling.

An Israeli based company has created a scanner that will be different from the present body scanner. The newly created scanner has not x-ray device, but have an enclosure with mouse in it. The working mouse is trained to smell 8 kinds of explosives. When a culprit carrying such explosive will pass under the scanner the smell of explosive make the mouse miserable, react and will run away from the place to the adjoining chamber, thus trigger an alarm.

Asthma detector

Every body know this fact that asthma gives a horrible pain when attacks to any person. Surely if the person will know about this attack earlier or at least one day before, he may mange for its prevention.

World renowned company Siemens has created a device that is a breath detector. This handy device tells the person who is going to be the victim of asthma at least one day before. In the mean time the person may take the proper medicine and prevent the disease.

It has been detected that the level of nitrogen oxide increases before one day when asthma attacks on our body. This detector may find nitric oxide at very low level. As the inflammation will be greater the higher will be the level of nitric oxide, hence will indicate the attack of disease. Doctors can suggest the medicine in this matter.

Device for paralyzed persons

When any person gets injuries after accident, he became paralyses and unable to move the organs of the body, now with the creation of an admirable device he may walk. The University of Louisville has plant an electrode lay out into the body of paralyzed person. This newly invented device is designed to send signals that accelerate the lower portion of the spinal cord. The spinal cord controls the movements of toes, as well as ankles, knees and hips. This tremendous device copies the signals of the brain apparent motions. The device accelerates the nerves in the spinal cord, which returns the required commands to the lower organs of the body. This top invention giving a possibility that paralyzed persons may overcome their disability.

If you are worried about how many calories you are going to consume in that slice of pizza, chocolate cake or fruits? A new invention may help you. After taking a picture of the edible with the new camera like invention, it gives a calorie read-out almost instantly. This device is called MealSnap, was developed by DailyBurn, a fitness social network that has created several other fitness and diet related inventions.

Within minutes of taking a picture of a meal and matching it to a database of some 500,000 food items, the device sends users an alert with a range of calories for the meal that was photographed. The database can quickly help identity the food, how many calories there are, proteins, fat, carbs, vitamins, whatever you may want to know. Users can then choose to share what they’ve eaten in any restaurant or hotel.

In past calorie counting was a very time consuming process, but the device make it easier to track the calories in food. Additionally, MealSnap can serve as a food diary, allowing users to keep a visual log of the meals they have eaten.
