Doorless Refrigerator

de-la-roche-ben

Refrigerators are one of the best inventions of all time. Ever since their creation, refrigerators have found their vital place in both the rich and middle-class homes to preserve food and to provide cooled food. The basic principle of cooling the box has never changed but the body, colour and structure are the factors which differentiate modern refrigerators from the older ones. A Massey University (in New Zealand) third year undergraduate student, Ben de la Roche, has come up with the idea of a new refrigeration “wall” which has absolutely no door and displays all the food so that you… read more

Cleaning Space Junk

Space junk

Space exploration is a very important and interesting field. With satellites and other materials going to space every day there are many things up there which simply shouldn’t be there. Space landfill is becoming a big problem and one cannot ignore that as it will pose a serious threat to operational satellites and future satellites. British engineer, Dr. Jaime Reed, has come up with an innovative way to clean this junk from space with the help of a space harpoon, measuring only 30cm in length. The harpoon would be mounted onto a chaser satellite which would take the harpoon to 100m… read more

Solar Power on a Canal

Gujarat, a State in India known for its medium and small scale industries is becoming a front-runner of clean energy compared to other states and recently a canal-topped solar power plant was inaugurated under its visionary chief minister Narendera Modi. This dual purpose project has grabbed the attention of the internet and other media sources recently making it trending news. This plant can generate 1 MW of power and the beauty is that it doesn’t require any land for solar panels! The entire solar panel is constructed above a 750 meter canal which passes through remote village of chandrasan. The entire cost of the project is… read more

Simple Things

Innovation in developing nations

Science has always helped mankind with all it can to make life simpler and healthier. Revolutions happen around the clock from fountain pens to rockets helping humans in one way or the other. Certain innovations are made accidently while some are invented to meet problems but in most of cases they don’t reach the common man quickly or are too pricey for them to afford. Simple technology and easy-to-use innovations are better in places where energy, education and materials are plentiful.  In developing countries where resources are scarce  it could even be as simple as developing a water bottle but it makes a… read more

Thermo Electric Uses

power from car tailpipe

We put lot of sweat and engineering to produce energy which runs our lives, but as much as two thirds of this energy gets dissipated as waste, particularly in the form of heat. Recent reports show that a new material can bridge the gap between energy produced and wastage through heat. An international team of researchers has developed a new material which generates charges from the temperature variations across its two ends. These thermo electric materials, when commercialised, will find their place in a variety of applications. Let’s take a simple example. A car drinks a lot of energy to… read more

Solar Fish

Solar Fish

The oceans and seas of our planet are still a mystery for humans, and yet contain millions of creatures. New species are regularly being discovered under the waves and scientists are curious to explore the deepest and furthest reaches of this frontier to better understand our planet and to gain inspiration for our future. The Sunfish, is an enormous, flat looking fish. It is become the inspiration for the designers at AeroVironment to craft an ocean swimming robot, Mola, which is driven only by solar energy. The locomotion of this robot is similar to the sunfish which periodically comes to the surface… read more

Dissolvable Electronics

Soluble electronics

In Lewis carroll’s Alice in Wonderland, Alice comes across the famous cat from Cheshire which discusses philosophy with Alice. After the talk the cat grins and disappears. The cat is gone but the grin stays. Electronic devices like Integrated circuits and CMOS have become an important part of life but what do we do once we are done with them? Throw them away? But this causes e-waste piles and it is estimated that these kinds of e-waste alone account up to 70% of toxic wastes currently found in landfills and a good percentage in the sea too. Electronic devices like pacemakers and… read more

Recycling Old Cell Phones

Recycling mobile phones

With insane revolution in both software and hardware, each and every day a new feature and a new model is pushed into the market.  In the early days people use to change bikes or their car when new models arrive but the latest trend is to stand outside the store even 12 hours before the product comes to the store. This is definitely something to be appreciated, but on the other hand when we buy a new high end phone we generally put the old phone to rest somewhere in a drawer along with messy accessories like its chargers or… read more

$9 Cardboard Bike

Cardboard Bicycle

In an effort to be more ecologically-friendly, over the last few years many people have started riding bicycles to work and using them for short distance travel.  This has forced bicycle designers to make the design more attractive and light weight. Many companies have already started replacing the heavy metals in bicycles with carbon fibre. But an Israeli researcher, Izhar Gafni, has designed a totally cool and innovate bicycle which is made from an even lighter material – cardboard. Typically like most other great innovations the first prototype of his cardboard bicycle design was a failure.  It looked unattractive and therefore… read more

Cooling Down The IT

Inside a data centre

Computers have virtually fashioned another world for humans, with recent encroachment like cloud computing, computers have become another home for humans giving them utmost services with a very little effort, but there is a serious problem with so called “data centres” which are volcanoes inside a room, it has been found in a recent research that more than half of energy consumed by data centres are used to cool down millions of processors inside boxes. This heightened problem has caught the attention of various design firms whose major job, now is to work in reducing the power consumed to cooling… read more
