DIAMOND BATTERY


A team of physicists and chemists from UNIVERSITY OF BRISTOL created this diamond with electric current that can last longer than the history of human civilization and more interestingly, it is powered by nuclear waste.

Why is it important?

Nuclear power has much more advantage compared with fossil fuel but when it comes to byproduct, nuclear waste is more harmful. The reason is that nuclear waste stays dangerously radioactive for thousands of years. So instead of dumping nuclear waste deep under Earth's surface, it can be used for making artificial diamonds which can provide current.

How is this artificial diamond battery is made?

Scientists used radioactive Nickel-63 for their first model and working on Carbon-14 for next model.Carbon-14 is the radioactive form of same element diamonds are made of.
In nuclear reactors Carbon-14 is found on the outside of graphite blocks which moderates the nuclear fission process enabling a controllable chain reaction.
When the usage of this graphite blocks are over, the radioactive Carbon-14 on the outside wall of the blocks are removed by heating and this isotope of carbon is then made into radioactive diamond at low pressure and high temperature.
This small diamond generate electric current when placed ina radioactive field . This gives a nuclear powered diamond battery. But still it is radioactive. For using it, another non radioactive diamond layer is formed around the radioactive diamond which completely absorb all the dangerous radiations and converting it into even more electricity. This final diamond product emits radiations less than that a single banana emits making it 100% efficient and safe to handle.
Radioactive Carbon-14 has a half life of 5730 years making it long lasting. So it can be used in satellites and even in pacemakers.
The development of this new technology solves some of the problems for nuclear waste, clean electricity generation and battery life truly taking us into the DIAMOND AGE of power generation.

The Gym that floats

Have you ever wondered how cool and refreshing it would have been to exercise or work out standing in the middle of a beautiful terrain or landscape may it be a park, ocean, mountain tops or magical city? Well now it's going to be possible with Paris's new floating gym, where one can enjoy the breath taking view of "The City of Lights" while running on a treadmill. 

This floating gym is a 20 meter long vessel which travels down the river by harvesting energy from the passengers workout. This gym was designed in collaboration with three major companies :Technogym, the leading fitness equipment manufacturer; Terreform ONE, a non-profit architecture group and URBEM, a urban regeneration institute. By doing exercise on the ARTIS bikes and cross trainers, people can continuously contribute to power the boat, which in turn will sail along the Seine on its route through the city, providing access to anybody who wants to use it.



The augmented-reality screens installed on the boat will show guests both the quantity of energy delivered from the workout, and data about the Seine’s environmental conditions that are tracked in real time by sensors incorporated on the vessel. Encased within a transparent glass covering, open in the summer, the gym allows an extraordinary view of the urban panorama. And at night, the boat can even be used for parties and celebrations.

How driver less cars work

Driver less cars are going to be the next step in the automobile world, also the biggest challenge faced by car manufacturers in the world. This so called concept was introduced in the late 1960s mainly in various hollywood sci-fi movies ( first movie 'Herbie' in 1969 ). 

Electronic sensors are the major components involved in the working of a driver less car. They are also called autonomous cars. The cars detect their surrounding using a Radar, Lidar, GPS, odometry and camers enabled computer vision. We are familiar with Radar and GPS, but what about Lidar, odometry and computer vision? Lidar is the combination of two words laser and radar. The distance of the object is measured by the time taken in sending and receiving the laser beam. Odometry is the use of data from motion sensors to estimate the change of an object's position over time. Computer vision is the process of converting visual images into descriptions that can interact with other processes and obtain actions by using a machine. The control system in the car analyse all the sensory data from these sources and then combine and make instantaneous decisions over time. 

Right now we are in a hyper innovative stage of development of driver less cars. No one knows what will happen and when it will happen. But of course it will happen soon and various companies such as Google, Tesla, Apple, Volvo etc are on the verge of introducing the vehicles into market. And soon drunken driving and rash driving will soon be in the history text books of our children.
