How Jackie Chan helped make solar cells better?

Supercop (Photo credit: Wikipedia)As the world warms up to using solar panels and harnessing the immense energy that is reflected back from the Earth everyday, there are still some major hurdles that we need to overcome before we can rely on this technology for all our energy needs.
Cost of solar panels has been a major point of debate but as governments around the world are encouraging consumers to adopt this technology, there are considerable grants pouring in to reduce the cost of installing solar panels and that is welcome relief.
The efficiency of the solar panel itself has been questioned on many occasions. General estimates of efficiency of solar panels has been put at 10-15%, which basically means that
these expensive panels are only capable of converting 10-15% of light incident on them into electricity.  Unarguably, this does sound quite low.  And has been picked up by detractors of renewable energy to ridicule. 
But did you know that the efficiency of gasoline powered engines st…

Solar ship! The answer to our fuel woes!

Flying has always been a human dream. Whether it be the Wright brothers in the past or the low-cost airlines in the present, all have worked towards making this dream come true. Luxuries of modern day flights are an added reason to take the aerial route to your destination.  However, the rising demand for fuel and shrinking supplies have taken away the 'low cost' from airlines. Increasing prices of flying not only affects flight enthusiasts but also affects activities such as large scale farming and emergency services such as air ambulances. Adapting a newer energy source will soon be a necessity in the future, but are we future ready? Well, the Solar ship is. 
We often look for ways to make our day-to-day lives more eco-friendly but Canada based Solar Ship has taken 'going green' to an all new level. Inspired by the Zeppelin's of the late 1800s, Solar Ship is developing aircraft that are powered by sunlight. Yes, sunlight powers the movement of these crafts that ca…

A Solar powered island

Image
A small island in the South Pacific Ocean recently shot to fame by becoming the first territory on our planet to derive its energy needs from the Sun. Covering a small area of 10 square kilometers, Tokelau is a part of New Zealand and lies to the North of Samoan islands.



Funded by the government of New  Zealand, Tokelau spent about $7 million to put in place three solar grids that will now enable its 1500 residents to harness and utilize solar energy for their daily needs. Why spend $7 million for a power plant in the middle of nowhere you might ask!

While the small island generates a small sum of $ 500,000 every year by selling agricultural produce, it spends over $2.8 million, most of which is spent of food and fuel. While its 1500 residents have energy needs like us, Tokelau's new means of earning is selling Internet domain names (like .com, .co.in, .au etc. ) with a .tk extension. With a booming internet business, electrical energy had become a primary need.

Besides, Tokelau h…
