Notebook: Lithium replaced Fuel Cell
The research was conducted during the Fuel Cell appears to be a real start to use in the production of Notebooks. Use of Fuel Cell will be applied in the notebook battery. If, using the notebook battery Lithium-ion (Li-ion) and Lithium-polymer (Li-po) as a source of energy in most portable devices.
Fuel Cell superiority as a source of energy have been examined since the year 1839 whereas for the development of notebook conducted in 2002
In 2002, various vendors such as Motorola, CASIO Computer, Hitachi and Toshiba introduced the Fuel Cell as a replacement source of energy Lithium. Ideally the use of the Fuel Cell is able to survive longer up to 10x of Lithium.
In 2005, with LG products portablenya holds strong perusahaanya that will become the first mengomersilkan Fuel Cell battery. With the weight of less than 1 kg, is believed able to generate 25 Watt or 10 hours of usage time.
In March 2006, Antig origin as a vendor in Taiwan stated that the products they use Fuel Cell will be sold to the public in 2007.
The first quarter of 2007, the Fuel Cell is not yet ready dikomersilkan. Until the mid-2007, Samsung's technology with Direct Methanol Fuel Cell (DMFC) were displayed to the public. Small size 150mm x 50mm x 50mm with a capacity of 2000W and the energy output of 20W.

Proof of God Particle
In these days, the fisikawan, astronom, and many kosmolog chew on a trial that will be done to menyimulasi natural conditions at the time of the new born. "God particle", is the principal problems that often be discussion among astronom in various parts of the world. "Particle" is believed as the beginning of the first creation of the universe. During more than 40 years of research continues to prove the theory is correct. And now napaknya research that will produce results, and the Large Hadron Collider is the answer.
Extraordinary events after teradinya big explosion (Big Bang), which occurred 14 billion years ago will be made "miniaturnya." Fisikawan English, Peter Higgs raised the most complex events in the universe will be known in the CERN Laboratory giant, which is located in Switzerland, France.
This laboratory has facilities Large Hadron Collider, which are known to spend up to 90 billion USD. The use of super-computer can not be separated from the part of the research.
"Miniature" Big Bang have this opportunity in two berenergi high speed and very high bertumbukan each other. From the collision, the changes will occur the proton structure. Therefore, analysis of each seper a second will bring important information.
Higgs theory that explains the existence of "God particle" bemula of wonderment bermasa objects that existed when the loss-bagiana broke into a size smaller. From this, Higgs Boson argues that the material first in the universe has no weight at the beginning of the first formation of the universe. However, material increases in line with the large increase in time.

Big Bang
How fisikawa suspect the universe came from the Big Bang? Edwin Hubble observations of the galaxy-galaxy is the beginning of the suspected explosion ever bear in the universe. In the observations, the galaxy consists of various stars and sky objects, while the center of the solar system called the Sun is one of the many stars in the Milky Way galaxy. Milky Way galaxy alone is one of many in the Andromeda galaxy, Andromeda and one from the collection of some other galaxy.
Hubble's view most of the galaxy has a color spectrum to the red (more short-wave). Based on the Doppler effect, the changes become more short-wave (a red) is a sign that an object moving DISTRIBUTION stray from the center, also with the galaxy.
If all the galaxy every time another stray one another, of course far in the past, galaxy-galaxy together. And here there is about the Big Bang theory, and according to the predicted events that occurred in the 14 billion years ago.
A very big explosion took place in the time sepersekian seconds. Setekah explosion occurred terecah core particles and result in the amount of energy, the core of the fraction and has grown to one another.

Fuel Cell must Price Decline
Fuel cell is one of the alternative energy instead of oil-friendly environment and have a high level of efficiency. Fuel cell introduced Himself is more than 10 years ago.
Principles used in the fuel cell is the reverse of the process that is elektrolisiss use of energy generated from the merger ion H and O. Hydrogen and oxygen are used as raw materials in the fuel cell because both are easily obtained and the number is considerable.
In the trades, fuel cell is not a place in the market, because the price is very high, 1 square meter cell membranfuel valuable reached 100,000 USD.
In the fuel cell of its development, the demand by the Sciences. One of the results of innovation that is found in Indonesia recently found by chemical experts from LIPI, Dr. Sunit Hendrana the sulfonasi the process for making polymer membranes. Membrane used as elektrilis, barrier between oxygen and hydrogen, that are not mixed directly in the container.
Membrane is coated by a thin platinum, which function as a catalyst in breaking the hydrogen atom from water. Proton of the hydrogen terionisasi is creeping through the membrane, while the electron can pass through membranes and there's so anoda occurred on the excess electron. What if this is connected kedia poles, electrons from anoda will flow to the cathode to be balanced, so there was a flow of electricity.
Research on the fuel cell has patented the process sulfonasi (The cluster sulphate) gas on the solid polymer to be able to deliver ion.
