Efficient Thin-Film Solar Cells

Scientists at MIT have just recently created more efficient ways to capture sunlight within thin-film solar cells. These solar cells are made of a new kind of silicon which are much more efficient and cost less. This new prototype combines a highly effective reflector on the back of a solar cell with an antireflective coating on the front. By adding silicon to these new types of solar cells, they can capture sunlight and produce electricity up to 15% more than the regular commercial cells. On modern solar cells each are backed with a metal layer which reflects light. Scientists backed surface of a silicon solar cell to make it so that it can capture and reflect sunlight. Scientists etch a series of ridges and troughs where on top they deposit a photonic crystal. The crystals make the light stay inside the cell longer increasing the chance of changing it into electricity. This new prototype can hopefully create enough electricity to where we now longer need power plants. This can help decrease the amount of pollution and decrease the effects of global warming.

Cancer nanobombs

Cancer is a serious problem and is hard to cure. Doctors usually use chemotherapy to get rid of some tumors that might spread throughout the body. Even if chemotherapy was to get rid of the tumors in the body there still would be major side effects.

Balaji Panchapakesan at the University of Delaware figured out a less risky way to get rid of tumors. He came up with the idea of Cancer Nanobombs. Cancer Nanobombs are tiny carbonNanotubes filled with water, which are injected into the area with the tumor. Then a laser light is zapped into the area causing the water inside the Nanotube to boil thus causing the Nanobombs to explode and kill any nearby cells.

Sure the Nanobombs will kill other cells along with the tumor cell but its better than the side effects of chemo.

Brazil's Technology

Brazil bets on technology to control Amazon. Every move was being watched from up in the sky, when the pilot of Colombian drug-smuggling plane landed at a clandestine air strip in the vast Amazon rain forest. The pilot got caught by a high –tech spy plane. A high-tech spy plane helps the police arrest a criminal with evidence and with no doubt. The Brazilian police arrested the pilot minutes later and confiscated 300 kg of cocaine. After this, Marcelo de Carvalho Lopes, head of the Amazon Protection System, or Sipam said, “We can't be everywhere, the region is huge. So we need intelligence to focus our resources," On the walls of one large conference room at Sipam's flying saucer-like headquarters in Brasilia, are the latest images of the areas worst affected by logging, taken with infrared cameras from Air Force planes. The images will be used as evidence in court against hundreds of illegal loggers. Currently, only 8 percent of all fines for illegal logging are collected, according to the environment ministry. The high-resolution images also show paths where loggers plan to chop trees, giving authorities a chance to prevent deforestation before it happens. By the end of the year, Brazil will have scanned 86 percent of the Amazon. With the high-resolution images it will gain an edge in law enforcement and conservation, analysts said. The problem is that the drug smuggling cocaine gangs enter from Colombia by boat instead of a plane to sell in Brazil or en route to markets in Europe.

Radeye PRD

Worried about gamma sickness or radiation sickness don't be due to the The RadEye PRD you can easily find out how much radiation is around you. The RadEye PRD or The RadEye Personal Radiation Detector is a high performance personal radiation detector.the RadEye is a good advance in hand held devices that can detect Gamma rays and x rays it also has a longer range compared to a regular dosimeter. the RadEye PRD is 5000 - 100000 times more sensitive than a typical electronic dosimeter. The main purpose of the Radeye PRD is to detect harmful substances in and around a certain area .

the RadEye PRD is equipped with a self alarming system witch will notify the operator if the amount of nuclear radiation detected in a certain area can be harmful to humans and or the environment lately the world has been having a problem which is know as the "orphan source"

this what they call it when gamma radiation appears in spots such as scrap yards and depots and other places which would be unlikely to have radiation under some peoples eyes.

This small hand held device can be thought of as maybe a hard device to use due to its long name FALSE. you see the device is actually quite simple to use with only three buttons on the screen to turn on you can simply press on and to view the radiation count in the room or within the vicinity of yourself you hold it and turn it what ever direction you would like to get an accurate and precise reading

I believe that this would is an ideal system and can be used to look out for the welfare and well being of people and the world

Large Hadron Collider

After nine years of construction, the seventeen mile long scientific instrument/experiment known as the Large Hadron Collider(LHC) is prepared to change our understanding of the world. The LHC is an enormous particle accelerator that shoots two beams of subatomic particles (Hadrons) around a track of tubing in opposite directions and "collides" them together. By colliding these particles together scientists are able to use detectors constructed for the LHC to examine the particles created by colliding the Hadrons together. One of the main goals of the LHC is to simulate conditions after the Big Bang in order to dicover new information on the origin of mass. Another is to learn more about Higgs Particle. Higgs is one of the last undiscovered territories in modern science.




The Large Hadron Collider will also play a large role in how the internet might work in the future. The LHC will be capable of teaching us how to transmit large quantities of data through to the internet. When the LHC is at it's full capacity it will be able to put out 5 Gigabytes of data every 5 seconds, with an annual output of about 15 million gigabytes. Compared to the capabilities of bandwith now the LHC can possibly revolutionize the internet.
