Harnessing kinetic energy under braking to get electricity. All car fans will already be accustomed to hearing the acronym KERS (KineticEnergyRecoverySystem). It is a regenerative braking system or braking energy recovery.

kers1

The principle of conservation of energy reminds us that "Energy is neither created nor destroyed, only transformed." And that's what it comes to making this system, using the kinetic energy that takes a vehicle during braking and turn it into electricity for later use. The energy is stored in batteries and used to power an electric motor.

The concept is not new, in fact, the trains were already using the regenerative brake. But perhaps we have not listened to his appearance in the Formula 1 (2009) and subsequent implementation in road vehicles.

How does it work?

All we have ever had one of those toy cars you should crawl back to wind them up, and once the loose continue their march for a while. Well, are based on a flywheel.

KERS also based on a flywheel that is a heavy wheel continues to rotate by inertia. The wheel has most of its mass divided by the periphery, this has a negative effect, as it makes it difficult to fast. The advantage is that once braking is hardly moving, due to inertia it takes.

When a moving vehicle requires braking, the wheel is connected to a flywheel, thanks to a special clutch system that engages. What you get is slow (partly because the car's brakes also act) the wheel, because the flywheel need to absorb some of the kinetic energy of the wheel to get going. When the wheel balance and the steering wheel at a certain speed, the clutch to disengage the wheel KERS. Once accelerated the flywheel, this shift can be exploited to generate electricity and store it for later use.

Now I leave you with a video of him running KERS

Simple, no? Well you know what happens in a Formula 1 car or in your hybrids when braking.

Tecnyo Today, I want to bring something different. Taking advantage of the Carnival approaching I'll give you a costume with insurance shall give the notice and will spend a good bit of fun. Mobile phone. Ends succumb to iPhone fashion and become one with these simple steps. Feel like?

guise-of-mobile-iphone-3gs

Today we want to make a note of joy to the blog and making approaching the Carnival we want to show how you can make a phone costume with some simple steps.

Material we need and the steps

We need a cardboard box and is elongated, which fully cover the bottom to leave just the legs, keeping in mind that we should walk in comfort. What follows is a large hole in the top for your head and leave our box rests on the shoulders. Finally, a measure that is comfortable, make two holes, one on each side for the arms.

Once we made ​​the mold, and just left us ins ...

Paint the box carrying the clothes of the same color to blend. With so original and colorful mobile that exist, we can even little imagination. The keys of the elaborate our screen with a cardboard color you want, paint over her numbers and letters, then pasting them on the box.

If we can complete our costume phone card with an antenna, but it is less bulky and place them on one of our shoulders, or even a cardboard glued on the bottom front of the case, it is right in front of the legs, simulating the part down with some of the older phones.

The name of the legendary Florentine astronomer again resound in our ears. This time, in draft form for satellite navigation. Gone are names like Omega and LORAN, old precursors of modern navigation system using radio frequency retransmissions.

galileosatelite

We Americans did the same with his NAVSTAR-GPS system (Global PositioningSystem), a project initiated by the Department of Defense of the United States. Initially conceived for use miliary, although later it "would open" for civilian use. Soviet Union also created GLONASS, currently managed by the Russian Federation Non-civil eigualmente.

The Republic of China and the European Union have refused to stay behind and prepare their own systems and GNSS (Global NavigationSateliteSystem), called Beidou and Galileo respectively.

EUGALILEO

Galileo is expected in 2018, after serious delays due to disagreements between countries and other technical problems. Recall that is a collaborative project which involved numerous paíseseuropeos and Europe like India and China. Other participating companies such as EADS, AENA, Hispasat, Inmarsat, Finmeccanica, Arcatel, ThalesAleniaSpace, Deutsche Telekom, German Aerospace Centre, etc.

The interesting thing about Galileo, other than that is completely designed for civilian use, are the features:

  • Will the accuracy of meters.
  • You will need a method of real-time navigation.
  • Ensure service availability thanks to its sturdiness.
  • May be used inside buildings.
  • Get combined with existing GNSS systems.
  • It will be a free public system.
  • It is used for control of land vehicles, and air traffic and boats.
  • Can be used for search and rescue work, allowing relief elenvió message and the precise location of alerts.

Currently, they have launched two test satellites and 4 others own the system. During 2013 and 2014 is estimated to be put into orbit another 18 satellites and so on up to the 30 to make the system fully functional. So ... wait!

Bioplastics: Biodegradable our technology

Here they are green alternatives to conventional plastic, the bioplastic . Agricultural by-products and other crops can supply our planet from the materials used in our era, plastics. Tecnyo Now you talk of bioplastics and their impact on current technology.

Unqualified

Just an ecological question?

The price of oil is much more expensive since 2005 and, therefore, resins which are obtained from conventional plastics (polypropylene, polyethylene, synthetic rubber, phenol polymers, polyesters, ...). Some have reached up to 80% and, moreover, not being biodegradable, present environmental problems. In short, from the standpoint of economic and ecological are not as well regarded.

Therefore bioplastics are gaining strength, among which the PLA (polylactic acid) and PHA (poly-hydroxy-alkanoates). These resins are plastics derived from natural oils (soybean, corn, wheat straw, vegetable skins or peels, potato starch, cane sugar, starch, etc.).

Alternatives and their applications

To search for cheaper raw materials and deal with environmental pressures, manufacturers are constantly looking for "bioalternativas". The world of electronics has not lagged behind in this respect and time to market these products. Some examples are:

  • 2003: Sanyo create a CD based on the PLA from corn. This technology would also be applicable to DVDs and Blu-Ray. Each disc 85 need some cereal grains, so that the cob with 10 discs can be achieved. IBM also experiments with PLA, a material with a great future.
  • 2004: Sony and Mitsubishi announced walkman biodegradable casings. This year, Pioneer developed an optical disc capable of storing 25GB and whose material is derived from corn (bio-disc). Meanwhile, a plastic invented plant NEC from polylactic acid.
  • 2005: Fujitsu began using bioplastics housings for laptops.
  • 2008: Samsung announced that their mobile phones W510 and F268 be manufactured with biodegradable casings.
  • 2010: University of Málagaen collaboration with the Materials Science Institute of Sevilla (CSIC-US), patented a bioplastic from tomato skin. The biopolymer is cutin, present in the leaves, the stems of the tomato and the tomato skin.
  • 2012: AIMPLAS and FERMAX, two Spanish companies, develop a bioplastic from agricultural residues, particularly wheat straw. With it you can make electronic products and appliances. In Europe there is a lot of wheat straw, which can transform into useful stuff from now on.

In short, there are many alternatives and increasingly green. We are not a world dependent on oil. The crude oil as an energy source and origin of raw materials, is another stage in our industrial history is coming to an end.
