Physics

Friday Fun. Symmetry Behind The Laws of Nature.

It’s Friday, time to learn something while enjoying this nice little animation from the Royal Institute. Produced by Ed Prosser, directed and animated byRosanna Wan, with sound design by Marian Mentrup this 4 minute short teaches about the laws of symmetry in nature and physics. You’ll learn about Emmy Noether’s theory that proves the need for symmetry and much more. Narrated by Tara Shears, this is an easy to follow piece with a great look and a nice rhythm to it. The weekend is here, get lost in a little bit of physics.

Who Wants Some Free Electricity?

This is a pretty interesting concept from IKEA’s Space 10 Lab. Think about all the wasted heat in your home from things like appliances, and solar gain. Imagine if you could take that energy and convert it to green electricity for tasks like charging your phone.

That is the clever idea behind the Heat Harvest concept designed by Sergey Komardenkov and Vihanga Gore. Komardenkov and Gore are students from the Copenhagen Institute of Interaction and during a two week workshop at IKEA’s Space10 innovation lab they came up with this concept and designed it. Heat Harvest is a concept for a device that can be used either as a stand alone object or be integrated into household items, such as a table, in order to capture wasted heat from our everyday objects and our surroundings and turn it into free, green electricity that can be reused at home. Pretty smart right?

By exploiting basic physics, and putting to use the fact that temperature differences between two surfaces can generate electricity Heat Harvest works. It captures that wasted energy and converts it into a clean energy source. By coupling it with recent developments in nanotechnology it is possible to make the conversion of heat to electricity more efficient than ever. If IKEA actually brings this to market, I’d snap one up in a heartbeat just to get rid of all the power vampires I have charging phones and tablets in my house.
