Say Hai to THOR…!!!

THOR hybrid UAV hovers like a helicopter, flies like a plane

We all know normal multicopter drones are effective at hovering and Vertical Take-Off and Landing, they can’t travel long-distance as efficiently as aircraft with fixed wings. This has been listed as their main disadvantage. But not any more. A team of students from the Singapore University of Technology and Design (SUTD) is trying to get the best of both worlds with the Transformable HOvering Rotorcraft (THOR).

First Generation of Batteryfree Cellphone!!!!

The battery-free phone prototype is comprised of a number of components you used to be able to buy at a Radio Shack: antennas, a power harvester to capture energy from ambient RF signals and solar cells, a microphone that listens for reflections and backscatter to record and transmit speech, a receiver, a headphone jack, a digital communication system, a small micro-controller, and a few LEDs and capacitive touch buttons for help with operating the device..

Don’t you ever felt frustrated and thought of throwing your phone away due to dying batteries in an emergency?? Here is some news, the recharging challenges with cellphones may get away from the new innovations from US.A team from the University of Washington have developed battery-free phone that can harness power from radio frequency (RF) waves sent to it from a nearby base station. The phone not only harnesses the power it needs to operate from those waves, but can also place a voice call by modifying and reflecting the same waves back to the base station, through a technique known as back scattering.

Why We Want to Redefine Kg???

Le Grand K

What we call a kg might soon change in future.? Yes you heard right, a substantial change to the International System of Units (SI) is currently under discussion and might be a reality by 2019. The General Conference on Weights and Measures (CGPM) is scheduled to have its 26th meeting in 2018 and will likely vote on a proposal put forward by the International Committee for Weights and Measures (CIPM) to revise the SI. According to this proposal, the structure of the SI will change fundamentally. The present SI is built upon seven base units: the metre, the second, the kilogram, the ampere, the kelvin, the mole, and the candela. The goal of the new SI is to define all of these units completely in terms of fundamental constants with exact values. Some constants, such as the speed of light, are currently defined in this way, as exact quantities. Continue reading “Why We Want to Redefine Kg???”

Goods & Service Tax System in India…

The Goods and Services Tax or GST is scheduled to be launched on the 1st of July, and it is set to revolutionize the way we do our taxes. GST is an indirect taxation wherein most of the existing taxes will be merged into a single taxation system. It will be the biggest tax reform since Independence. The major flaws in the current tax system such as cascading of taxes,multiplicity of law and taxes, non-fungibility of credits between goods and services and various distortions existing may be removed by this destination based tax system.

New Solid-state Battery calls for Another Battery Revolution…

A noncombustible design and can recharge in a fraction of the time of a standard battery.

Have you ever wondered what 94 year old John Goodenough, co-inventor of the lithium-ion battery, is doing?? He is hoping to find another breakthrough in battery technology. I think, he has succeded. A team of scientists under him has developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage. Continue reading “New Solid-state Battery calls for Another Battery Revolution…”

Is Jack fruit a substitute staple food??

Jackfruit

Which fruit is the largest tree fruit in the world, do you think you could get the answer? Yes, if u said Jackfruit, then u r right. Our own jackfruit. Jackfruit is the largest known tree borne fruit. Even a small jackfruit weighs in at 10-15lbs (5-7kg), and farmers have recorded specimens of more than 100lbs (45kg). Jackfruit is believed to have originated in Southern India thousands of years ago,now cultivated worldwide in the tropical regions of the Indian subcontinent, Thailand, Malaysia, Indonesia and Brazil for its fruit, seeds, and wood. The tree grows best in tropical humid and rainy climates but rarely survives cold and frosty condition.

Magical Graphene Sieve for Sea water

Producing potable water through desalination may become more efficient and less energy-intensive if researchers at the University of Manchester are able to successfully use graphene oxide (GO) membranes to filter common salts in seawater on a commercial scale.

About 97 percent of the Earth’s water can be found in our oceans.With ever increasing needs of growing population, the problem of pure, clean drinking water is alsogrowing. Providing clean drinking water for millions of people who struggle to access adequate clean water sources is still a challenge. Scientists from the University of Manchester, led by Dr Rahul Nair, show how they solved some of the challenges by using a chemical derivative called graphene oxide. An effective and less energy-intensive desalination process using graphene has been developed which could give millions of people access to clean water.

Is Smart Drugs Smart???

Student life has changed., They Substitute Smart Drugs for Cofee

Don’t be surprised if you see your children taking a pill before exam or before an interview??  Just as you might drink a cup of coffee to help you stay alert, they are turning to prescription drugs to boost academic performance. The pill, that they have taken, would instantly make them work harder, improve their brain function and make them much “smarter”. These are Performance-enhancing drugs or Smart Drugs!!! Not familiar??? Yes, its new way of youngsters to boost up their mind. Continue reading “Is Smart Drugs Smart???”
