Toyota’s New i-Road Is A Single Seater Car That Looks Straight Out Of Future
Toyota’s New i-Road Is A Single Seater Car That Looks Straight Out Of Future
We are running out of space on earth. The roads are becoming more and more congested and engineers are busy trying to come up with new methods to tackle this congestion. We are also suffering at the hands of carbon emissions due to combustion fuel vehicles and there is a dire need to shift to electric vehicles. However, the Urban Transportation is too big of a challenge and that is why it requires a lot of commitment if you are willing to redesign it. Who is up to the task? Well, Toyota has come up with a green technology to tackle this situation.
On 2nd March, at Ecoful Town, Toyota City, we witnessed Japanese drivers trying out the new i-ROAD on public roads and experiencing what the future of transportation will look like. This event was a part of the future that Toyota has envisioned for urban transportation. i-ROAD will also be making appearance at Grenoble, France later in 2014. This demonstration will also be aimed at bringing this idea to public knowledge and let them get a feel of the future.
This whole endeavor is basically a joint venture of Toyota Motor Corporation, city of Grenoble and Électricité de France (EDF) and others. We will be witnessing around 70 electric vehicles including the i-ROAD that shall be participating in this event and will be contributing towards a car-sharing project. i-ROAD is expected to be available both in Japan and Europe upon its debut (commercially) and it is being considered as a solution which is viable both in terms of environment and mobility.
Speaking of i-ROAD, it is a three-wheeled EV, which is capable of moving quite easily in narrow spaces while helping to reduce the congestion in traffic. Parking spaces required for i-ROAD shall be minimal and that will keep parking fees low as well. Since it is electric, emissions will be non-existent, thus providing us with a cleaner environment. The traffic footprint will reduce dramatically while allowing for easier navigation and hence, traffic jams won’t be a problem anymore.
The whole project is essentially a combination of public transportation and EVs to allow you to move from one place to another. I-Road is definitely a step in the right direction for optimized future urban transportation.

Story of the Biggest Experiment in History Caught on Film
Story of the Biggest Experiment in History Caught on Film
scientists around the world waited with bated breath for the announcement that the long-awaited Higgs boson particle had been discovered. The finding — the result of the biggest and most expensive experiment in history — was set to either confirm reigning models of particle physics, or reveal gaps in scientists' understanding of the universe."I knew this big event was coming, and I wanted it recorded," said producer David Kaplan, a physicist at Johns Hopkins University in Baltimore, Md. "I knew it was going to be extremely dramatic scientifically, and also emotionally, for all of my colleagues," Kaplan told Live Science.
But to understand why scientists need the LHC, one first has to understand the hypotheses it is putting to the test.
Supersymmetry vs. multiverse
An extension of the Standard Model known as supersymmetry suggests a highly structured and symmetrical universe, in which every particle has a supersymmetric twin that has yet to be discovered. Another, somewhat radical hypothesis suggests the known universe is part of a much larger, chaotic multiverse, in which the laws of physics are random.
The film pits Kaplan and Stanford theorist Savas Dimopoulos, proponents of supersymmetry, against the young Princeton theorist Nima Arkani-Hamed, a supporter of the multiverse idea. The LHC offers the chance to test these hypotheses for the first time. If supersymmetry proves itself, physicists are on the right track. On the other hand, "We may fall off a cliff," and find that the fundamental laws of physics turn out to be random, Kaplan said.
Biggest experiment in history
The beam test went off successfully in 2008, but a few weeks later, a catastrophic explosion in the facility vented liquid helium, damaging many of the magnets inside the LHC.
"The whole film changed," said director Mark Levinson, who added he didn't know how long it would take to fix the damage, and whether the film would have a happy ending. Fortunately, repairs were completed, and the collider was up and running by November 2009.
Fast-forward to July 2012, and the discovery of the Higgs. The particle observed by the LHC confirmed what physicists had long suspected, but also brought up new questions.
Most supersymmetry models predict a Higgs boson with a mass of about 115 gigaelectronvolts, or GeV, whereas multiverse models predict a heavier mass of about 140 GeV. The Higgs observed by the LHC was about 125 GeV — smack in the middle, which doesn't confirm or rule out either theory. Instead, it merely narrows down the possibilities.
It's like being lost in the woods, and then getting a hint of the broad direction you should go, Kaplan said, adding, "At least you know which way to start walking."
In the next step, scientists will collide protons at higher energies, to see if even more particles are created, as predicted by supersymmetry. The LHC was shut down for upgrades in 2013, with plans to reopen it running at twice the power in 2015.
The filmmakers hope "Particle Fever" gives audiences an appreciation of particle physics, and gets them excited about learning more. As Kaplan said, "We want people to come out thinking physics is awesome."

Solar-Powered Drone Could Fly Nonstop For Five Years
Though
many people immediately associate unmanned drones with military use or some
kind of dubious espionage activity, but they have incredible potential to be
used in a wide variety of peaceful and scientific applications. In addition to
delivering supplies to disaster-stricken areas, drones could be used to gather
information about things like weather and wildlife.
Titan
Aerospace is currently developing a drone named Solara
50 that is being hailed as an “atmospheric satellite” and has quite
a lot to offer in terms of gathering scientific data. The drone will fly at an
altitude of over 19,000 meters (65,000 feet) where there is little air traffic
and above most weather that could impede its travels. Flying at that height
will also give it unobstructed access to the sun, which will power the 3,000
solar cells that cover its 50-meter-long (164 feet) wings. The solar cells will
also charge lithium ion batteries stored inside the wing so it can fly at
night, which means that this drone can fly uninterrupted for up to 5 years all
while producing zero emissions.
The
body of the drone is durable carbon fiber, and the 5-kilowatt electric motor
will allow the aircraft to cruise at about 96 km/h (60 mph). Though the
aircraft itself weighs only 160 kg (350 lbs), it will be able to carry 32 kg
(70 lbs) worth of payload up into the stratosphere.
Solara
50 is completely self-piloted; able to take off, cruise, and land on its own.
It will function much the same way as a satellite, though it will cost much
less to launch. From the air, it would be able to track developing storms,
migrating wildlife, vegetation patterns, and it would also have data
communications capabilities; a feature that has caught the eye of the social
media giant, Facebook.
Facebook
would use the drones to bring the internet to the 5 billion people around the
globe who aren’t online as part of the Internet.org initiative. They are
interested in acquiring Titan Aerospace for an
estimated $60 million. If it goes through, Facebook will launch 11,000 units to
start, which would be used to connect rural regions in Africa to the rest of
the world. This is a similar—yet more sophisticated—concept as Google’s Project Loon,
which had the same internet connectivity goals in mind though it utilized
weather balloons instead of precision-guided drones.
If
Facebook does acquire Titan Aerospace and all of its drone technology, all of
the units produced will be used to further Internet.org’s goals.
