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.”

Rubber Mulch: Safer playgrounds

Rubber Mulch: Safer playgrounds, Landscape Rubber Mulch and Surefoot Arena Rubber Footing.

Recycled tires used at children’s playgrounds!!  Zach and I recently saw numerous playgrounds in the Madison area that are covered with recycled tire mulch. This seemed to be softer and more resistant than wood chips, sand, pebbles, etc. The mulch can improve overall safety for children while playing, while there are also other options like soft play areas which you can get from sites like

Today, I am researching where I would like to recycle my tires from my vehicle. Piling them up in a landfill will not be the best option for me. This site provides information about the types of products that are being made from recycled tires.

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?
