Doomsday – Hoax Or Here?

www.dropofoil.com

The Doomsday Conspiracy flooded the internet for more than four years leading up to its supposedly deadline. The date for the end of the world was set as 21/12/2012 and was such a virulent conspiracy it even sparked a movie being made about it. Around the world people held their breath and waited anxiously. But it all passed just like any other day. So is the Doomsday Conspiracy dead in the water? As there is no actual date for the origin of the Earth, then it is unlikely to have a final date. It is clear that Earth was not created in… read more

Making Solar Cheaper

Cost of Solar

Recently a California-based company named Alta Devices announced the news that it had achieved a record for the efficiency of an individual solar cell. Alta Devices have broken their own previous record of 23.5% and the new efficiency levels of 27.6% has been verified by the National Renewable Energy Laboratory. Alta Devices makes solar panels using gallium arsenide. Gallium arsenide is a more efficient material than the silicon-based cells which are currently more prevalent. To keep prices down the company uses remarkably small amounts of gallium and arsenic. This is done by creating layers of gallium arsenide only a micron thick. The development… read more

Simplifying Modern Life

Technology makes life easier and more convenient. With the advancements in software and micro chip design, technology has enabled consumers to reduce their carbon footprint by consolidating many devices into one. For instance, it is no longer necessary to carry a camera, or an mp3 player, or a GPS or a laptop or a gaming console or an eBook. Instead a compact Smartphone can do the work of all the above mentioned devices and proves the proverb that “good things come in small packages”. Due to the personal nature of this mobile technology, we as consumers can modify our behaviour… read more

Green Efforts: Berlin

Potsdamer_Platz

In part three of Green Efforts, we take a brief tour of Berlin. A city who, like the previous two destinations, has seen its fair share of hardships, if not more. But the once divided city is now a leading innovator for technology and design, especially in architectural design and transport. As a world class city, Berlin has a smorgasbord of  amenities to offer and its leading efforts in efficient living are no exception. That said, we will highlight some of Berlin’s greatest green assets, both intentional and accidental. Bike Friendly Bike riding is a common practice is Berlin and… read more

Air Energy Storage

2R5DR1~Z

While more efforts are being taken to generate energy through various methods very little research is being done on the field of storing energy. This is an extremely significant criterion because energy demands will not be the same all the time and there must be an efficient system to store the produced energy. Air medium is used for many purposes such as communication, transportation etc, but the next generation energy storage will be carried out with the help of air. Compressed Air Energy Storage may look like a new concept but it has a history dating way back. During late… read more

Making Buildings Greener

Making a building greener

We’ve heard it time and time again in the news – “LEED is fine, but these touted green buildings use more energy than other buildings”. Or “LEED is great, but the buildings use more energy than predicted!”  Hold on – let’s take a look. First, many LEED buildings do use more energy than other buildings.  What is being compared? A science lab from 1940 will have entirely different usage parameters for energy, even if upgraded, than a science lab from 2012. A classroom of today employs better lighting and more controls and hopefully includes exceptional insulation and integration of daylight, but… read more

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

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

Why Move to Electric?

Electric cars - the future

Are electric cars the future? If you are a person that likes to save money or the environment, gas powered vehicles are not for you.  Only the electric alternative will save you money on a regular basis and help protect our environment. One advantage of an electric car is the complete nonexistent emissions.  A full electric vehicle will not have an exhaust system, fuel tank or muffler.  Another great thing about electric vehicles is how they use absolutely no fossil fuels under the hood.  The rechargeable battery is just an added benefit to owning an electric car.  As is the… read more
