Laptops Powered by Typing, Pacemakers Powered by Blood Pressure

Research at Australia’s Royal Melbourne Institute of Technology (RMIT) demonstrates how mechanical pressure can be turned into electricity via a nano-scaled piezoelectic film.

The team’s research lead, Dr. Madhu Bhaskaran explained, “Our study focused on thin film coatings, because we believe they hold the only practical possibility of integrating piezoelectrics into existing electronic technology. The power of piezoelectrics could be integrated into running shoes to charge mobile phones, enable laptops to be powered through typing or even used to convert blood pressure into a power source for pacemakers — essentially creating an everlasting battery.”

National Geographic-Green Energy Challenge

National Geographic is hosting a great energy challenge that is available for everyone to check out. There are informative quizzes and a personal energy meter that allows you to have a closer look at your use. After seeing our results from the meter, we discovered the greatest energy used in our home is electricity.

What do you think your greatest energy use is? Any guesses?

12-Year Old’s Solar Cell Absorbs 500 Times the Light of Existing Cells

Solar Rays

William Yuan, a 12-year old boy from Beaverton, Oregon, has developed a new 3D solar cell which if it ever gets commercialized could seriously change the face of solar power. Though he was encouraged in his research from his middle school science teacher, this is no mere school science experiment: the Davidson Institute has awarded Yuan a $25,000 scholarship for his research.

Experiment Confirms Space-Time Vortex Around Earth




In the early 1900s, Albert Einstein postulated a theory of gravitation he called Relativity. In it, he said a bunch of seemingly crazy things about light bending, objects with mass dragging space and time along with them, and how the universe is hurtling away from itself–an expansion occurring at the speed of light. According to NASA, another facet of his theory has now been verified.
