Modern advancements in technology led to new ways of generating sustainable energy. More and more countries are turning to sustainable energy to power cities as well as to preserve the environment.
German architect Andre Broessel takes sustainability a step further by introducing a spherical sun-tracking solar energy-generating globe that is said to be the next big thing in renewable energy. His project uses a giant glass sphere that is mounted on a steel frame with the ability to concentrate both light and moonlight by 10,000 times the normal. This makes his machine 35% more efficient than the conventional solar panels.
This invention made Broessel a finalist in the World Technology Award 2013. Soon after, he introduced an improved version he called Betaray, which has the ability to concentrate diffused light thus allowing it to harness sunlight even when it is cloudy.
