This New Super-Battery Was Inspired By A Pomegranate :
BIOMIMICRY PROVIDED THE INVENTIVE SPARK FOR THE LATEST, AND MOST PROMISING, REVAMP OF THE RECHARGEABLE BATTERY.
- The rechargeable battery,which always disappoint you with its performance in this new digital era of smart gadgets.
- Indeed, scientists have been swallowing years on a lithium-ion battery with a longer lifespan.
- But who would've thought that the inspiration for the most promising new design of batteries would come from inside a pomegranate?
- Yes, this promising new design has been Developed over the course of eight years by a team at Stanford and the Department of Energy’s SLAC National Accelerator lab,
- This new battery houses silicon nanoparticles clustered inside like pomegranate seeds within a rind of carbontraces.
- Similar to the way pomegranate fruits pack more antioxidant punch than blueberries, silicon anodes (a battery’s negative electrodes) can store 10 times more charge than the graphite anodes currently used in lithium-ion batteries.
- But historically, silicon has proved difficult to use in batteries, because it gets brittle and break easy property. and Additional to this, silicon reacts with other chemicals in batteries, creating a gunk that eventually kills the whole system and making it dead.
- The designers at Stanford solved this problem by encasing the silicon nanoparticles in a cozy membrane of carbon--much like the way pomegranate seeds are housed within a squishy pulp.
- During charging, the silicon seeds can swell within the membrane, lessening breakage and reducing gunky interactions between silicon and other battery chemicals.
- And their had been a news that,Experiments showed our pomegranate-inspired anode operates at 97% capacity even after 1,000 cycles of charging and discharging, which puts it well within the desired range for commercial operation," said Yi Cui, associate professor at Stanford and lead researcher, in a press release.
- "While a couple of challenges remain, this design brings us closer to using silicon anodes in smaller, lighter and more powerful batteries for products like cell phones, tablets and electric cars.”
- It might take few more years,before you start charging your very own pomegranate battery--the designers are still perfecting the design and are sourcing cheaper silicon particles to make it affordable for the consumer market. But however long it takes, it's an exciting step in battery design.
- It appears this hyped superfood is good news not just for the health world, but for the tech world, too.with an attitude of better and peaceful future and promising concepts good day have exiciting surfing on our pages
Smart phones are very common today. But over use of the gadget causes eye problems like aching eyes, blurred vision, dry eyes from inadequate blinking, and headache from prolonged use.
If the user is already wearing spectacles or contact lenses, the problem tend to be worse since the eyes have to compensate for the optical aids apart from the strain. All this is due to the fact that most users tend to bring the phone close to the eye.
Another hassle is using a smartphone while travelling. The jolts and shakes of travel-whether by car,bus or train-also increase the stress.
Simple reviewing causes the smartphone to be held at a 14-16 inch distance, prolonged viewing especially in the young is often at 10-12 inches. In excess,this can lead to MYOPIA.multiple reports have shown an increasing number of cases of myopia in young adults.
What is the solution? smart phones are now so appearing that one cannot do without them.
Here are few tips:
1. Reduce the time spent on these devices and get a device with a larger screen.2. Use the device only for the minimum required quantum of work on a 4 inch screen device.
3. Restrict daily e-mail activities to a computer with a large screen.
A common technique of reducing eye strain by computer use - the 20-5 system, whereby for every 20 minutes of work, five minutes are devoted to looking at a point on the horizon that relaxes the accommodation muscles and prevents eyestrain from developing - is equally applicable to the smartphone.
MILITARY ROBOTS TO GUARD 2014 WORLD CUP :
- This year’s World Cup has thirty new soldiers that will be tasked with protecting and monitoring 12 cities during the games.
- They are PackBots from iRobot, and they will be rolling around keeping everyone safe very soon.
- PackBots are one of the most versatile designs from iRobot for searching an urban area for anything dangerous and destructive.
- They can even travel in water up to two meters deep if necessary, and can climb most stairs with relative ease with its powerful design. The Brazilian government has entered into a $7.2 million deal with iRobot to see 30 of these machines deployed in 12 cities during the World Cup, just to make sure everyone is safe.
- Given their size and maneuverability, PackBots would be able to be used as perimeter monitors
- where found to be attempted or similar dangerous situations can be deployed on the event
- These bots can be remotely controlled from great distances, and offer the driver everything from HD imaging to temperature readouts while putting as few people in danger as possible.
- They are also small enough that there’s a good chance an excited crowd might see one and try to walk away with it during the celebrations, but I’d wager the Brazilian government has a few ideas on how to discourage that kind of behavior.
- However, this packbots could not be a substitute for human security and with a taunt that Brazilian government is just making an attempt to make this event more eye catchy.
RALLY FIGHTER :
- This new thrilling new monster is the first fruit of the tree LOCAL MOTORS.
- Local Motors started their production with this vehicle. They’re a community where engineers, designers, and manufacturers can work together on new designs and ideas.
- Designer is Sangho Kim who is student at Art Center College of Design. The power source is typical American “muscle” engine – 6.2 liter V8 engine with 430 HP. This vehicle is offered with several options, such as leather interior, satellite navigation system, power windows ,locks and more.
- It’s main purpose is off-road activities, but the Rally Fighter is street legal and it would not look ridiculous in urban conditions too.
- And this beautiful monster is available to you with a price tag from $74,900 and depending on options you want to include, the price may grow to $80 000.
- What is unusual from the most common cars is the Rally Fighter needs to be assembled before you can drive it.
- yes exactly, you will receive the vehicle disassembled, in kit form, and needs to be assembled by you in order to drive it. But at least you’ll be guided, purchasing the Rally Fighter leads you to what is known as the “Local Motors Build Experience”.
- And this what i call a passion where the monster is assembled as per customers desire.
- That means that you’ll have to spend two 3-days-long weekends in the Phoenix Micro-Factory of the company. There you’ll be supervised and supported by Local Motors experts. So, if you want to become an expert about your vehicle, prepare some $75k and enjoy your time .
" SUPERSONIC SPEED FOR THOSE WHO BELIEVE TIME IS MONEY " :
- In business, time is money, and that’s exactly what the designers at Spike Aerospace had in mind when they dreamt up the Spike S-512 jet.
- This awesome design Measuring in at 40m (131ft) long with a wingspan of 18m (60ft), the S-512 is built to carry 18 passengers from point A to point B post-haste. With a cruising speed of Mach 1.6 and a top speed of Mach 1.8, and thats too fast than thr current world's fastest business jet, the Gulf-stream G650 as well as the upcoming cessna citation X with a top speeds of .875 and .935 Mach respectively. the S-512 is looking to become the World’s first supersonic private jet.
- At those speeds, Spike claims that its S-512 will clip 3 hours off the six to seven hour jaunt from New York to LA and slash the transit time from LA to Tokyo in half. Taken in total, a one-way trip from New York to Tokyo could be done in about 13 hours.
- However, given the jet’s 7,400 km (4,600 mile) range, making it a big lag off for time
- And With initial designs only just unveiled; Spike Aerospace’s jet could still see much reconfiguration in the coming months and years.
- For now, the company is stating that its speedy jet will run customers $60-$80 million each; maybe a bit too pricey for individual use, but certainly in the realm of possibility for large, multi-national corporations.
- Although its initial designs are impressive, Spike Aerospace still has a lot to prove before it convinces investors to support the firm. One of the S-512’s most puzzling mysteries is how it will deal with the requisite sonic boom that accompanies supersonic flight.
- With strict FAA regulation limiting how and where the phenomenon can occur, the S-512 might find itself entering a niche aerospace realm home only to the commercially unviable Concorde. while Cessna citation X awaiting for FAA certification.
- If Spike Aerospace can successfully navigate its regulatory and design hurdles the company expects its first supersonic private jet to hit the runway in December 2018.
- Details are still scarce on this project-including how it gets around whole sonic boom issues and more...
- As this project is just on imagination and papers here's a time to wait it to watch it as a reality for bossiness tycoons
- well to those who could not afford this just get excited with its design and sonic booming speed, for more updates stay connected with us
Schwerer Gustav and Dora :
Role of cannons during world world-2:
- A destructive feature of the World War II artillery is the cannons .Usage of these canons in 20th century began with the Big Bertha (also known as the “Fat Bertha”) during World War I. Big Bertha proved its effectiveness against older fortifications by destroying several Belgian and French forts.
- However, these cannons were almost helpless against newer constructions built of concrete reinforced by steel.
Evalution of these useless powerful monsters machines :
- Now let’s take a look over the largest cannons ever used in battle. These are the 800 mm Schwerer Gustav and Dora, railway guns developed by the Krupp family company who also developed the Big Bertha cannons in WWI.
- They were designed in the 1930s in order to destroy the strongest defensive facilities of their time – the Maginot Line in France.
- This defensive line was built by the French people along the frontier with Germany and consisted of different obstacles, concrete bunkers and fortifications, and weapons installations. For that purpose cannons should be able to destroy 1 meter thick layer of steel or 7 meter wide wall of reinforced concrete.
- When the war began, the Wehrmacht invaded France by passing through Belgium, thus escaping the Maginot Line and conquering France without necessity of destroying the defensive line.
- Schwerer Gustav was 1350 tons heavy and was capable of firing 7 tons heavy projectiles at a distance of 47 km.
- The gun was destroyed in order to avoid capturing. The Schwerer Gustav
- cousin – Dora, was intended to be used at the siege of Stalingrad. The menace of Soviet capturing forced German army to withdraw Dora from the siege. and later Dora was also destroyed before the end of the war.
- The project was called Landkreuzer P. 1500 Monster and had to be powered by 4 submarine diesel engines. It was planned to be armed with Schwerer Gustav as main cannon and two smaller, 150 mm howitzers. The armament would have also included several 15 mm machine guns for air defense. The project was cancelled in 1943 and it remained on the drawing table only.
- Above are some snaps of these monster machines which remained as in papers
- yes, though these machines were not used they had been considered as the most innovative and fragile
- though the power of these monster machines when compared to present mini drones is not competable over itz structure could itself fill a fear in your hearts
- Any thing to say..? just find me in comments
A car for disabled people :
- Kenguru is an electric vehicle created especially to serve disabled people on wheelchairs.
- This vehicle will allow such people to feel less helpless and more independent by providing them the ability to go to the shop, for example, on their own. And eliminating the necessity of a personal assistant or engaging of a family member for that purpose.
- Modifying of a regular car to be suitable for wheelchair users may cost up to $80 000 which is too expensive for many people.
- Kenguru (which means “kangaroo” in Hungarian and some other European languages) has body of fiberglass that weighs around 350 kg (772 pounds).
- This weight is increased by the batteries which add another 194kg to reach overall weight of 544 kg (1200 pounds).
- Batteries provide power for a pair of 2kW electric motors which propel the rear wheels. “A pair of 2kW electric motors” means that the overall power output is just slightly more than 5 hp.
- This power allows top speed of just 45 km/h (28 mph). However, a disabled person doesn’t need a powerful racing car.
- He or she just needs to reach from point A to point B as safe as possible, which makes understandable such “non powerful” characteristics.
- Being a single passenger vehicle defines the small dimensions of the vehicle. Its length is 212 cm (83.6 inches) and is wide 162 cm (63.8 inches), which is a little shorter and just slightly wider than two seats Smart car.
- The battery charge provides range between 69 and 109 km (43 and 68 miles). The vehicle could overwhelm slopes with angle of up to 20 degrees.
- The micro car is accessible through a single door at the rear side and there is a space for one wheelchair passenger inside. The driver directs the car via handles like in a motorcycle.
- The company is trying to develop and a joystick controller and Kenguru initiated crowd-funded campaign on RocketHub
- Each Kenguru could be bought for $25 000 but the price could be lowered in case of available rehabilitation or electric vehicles incentives.
- The car was developed in Hungary, but the lack of funding brought Kenguru in Pflugerville, Texas, USA.
- It was done by Stacy Zoern, a lawyer in the same city who got tired of all obstacles she faces as a wheelchair user.
" Thee Greatest Engineer's Of All Time "
National Instruments decided to respect the National Engineers Week by an attempt to this honorable list.
10. Roy Hinkley:
This is the professor from the Gilligan’s Island, a comic sitcom that was on TV for 3 years between 1964 and 1967. The professor became famous for his creativity and ability to create and fix almost everything. “Almost” means everything except the ship that wrecked and left them on the island. Professor Hinkley was suggested for first by user nicknamed @FlyBucket.
9. Mark Zuckerberg:
Is it necessary to mention that this is the father of Facebook? His web “creature” has changed the internet and became the first real opponent of Google. The suggestion for him came from Sam D on Facebook.
8. The Men of the Manhattan Project:
This is the public name of the project responsible for the development of the atomic bomb. “The guys that actually figured out the atomic bomb are generally referred to as scientists,” noted PigSlam on Reddit. “But what they did was take a very abstract theory and create a functional device from it, which seems a lot like engineering to me.”
7. Archimedes:
This man is an ancient scientist. Yes, we can’t call him separately a mathematician, engineer, physicist, astronomer or inventor, because he was a collective image for all of these scientist types
6. Clarence “Kelly” Johnson:
This man is designing airplanes from his early childhood and won his first award for this at the age of 13. Later he started working for Lockheed and his most famous aircraft is the U2 recon airplane. His motto is “Keep it simple, stupid.” Kelly Johnson was proposed by Inigo93.
5. William Thompson:
First Lord Kelvin. Mathematician, physicist and also inventor, he discovered the “absolute zero” and he also improved the compass. The proposal for him came from Implicit_none via Twitter: “Up until his time, engineers were basically tradesmen– skilled craftsmen, [without] any scientific knowledge at all… Physics was still generally called “Natural Philosophy.”
4. Leonardo da Vinci:
Although he is most famous as an artist, his works regarding human anatomy and engineering make him a scientific pioneer for his time. He was proposed by many users on Facebook, Reddit and Twitter.
3. Nikola Tesla:
The Serbian engineer became famous for his works in the field of electricity. Dyson201 said: “From polyphase power transmission to wireless signaling, Tesla was truly a master of electricity. He understood exactly what it was and exactly what it could do, and he produced fantastic ideas and inventions from this mastery.” But there are many people who dislike the image of Tesla: “Being an engineer is more than just inventing stuff,” said JustStopDude on Reddit. “There is no point in having great ideas if you can’t get them utilized. That takes communication, project management, and business skill. Tesla was his own worst enemy.”
2. Anthony “Tony” Stark:
Yes, that’s – the developer of the Iron Man suit. Although not a real person, this movie character makes a lot of children passionate about the engineering science. “Without [Tony Stark], I couldn’t dream big as an engineer myself,” said Sam Djanani on Facebook.
1. William Shockley:
This is the man who played a significant role into the invention of the transistor. As Derphurr stated, “[Shockley’s] contribution to the development of transistors, which led to the explosion of technology and Silicon Valley, and also led to NSA monitoring everything you do or say online” led him to the first place of this chart.
