Good vibrations for energy harvesting
Submitted by Evan on Fri, 12/12/2008 - 7:58amPublished in
Here is an interesting article for all you engineers out there, or for very brave students. It talks about an electronics kit you can buy to power products via energy harvested from vibrations. Very cool!

For next year, maybe the Niu can be powered by water........ can it???
Just What is Project Niu All About?
A lot of people have asked me about Project Niu, and just what is it? Is it an excuse to go the beach? To play with really cool toys? To make kids do science homework?
Well, the answer is longer than you might think. But it is also a really incredible, and extremely interesting project.
Alternative & Renewable Energy Sources
Published in
A number of technologies exist to harness energy from renewable sources (solar, wind, waves, etc.) and from other alternatives to fossil fuels (such as biofuels). This lesson plan explores the current state of the art of these technologies, their pro’s and con’s, and their readiness for adoption. These may accompany a science/technology lesson in which students build and evaluate the effectiveness of small devices that are powered by alternative fuels (small solar panels, wind, kinetic energy, etc.).
Globalization & the Environment
Published in
The past century is only a fraction of the time that people have existed in the world, but we have done more to change the planet in that time than in all of history before that. International trade, air travel, and the Internet have made it possible for someone to be surrounded by products, people, and information from thousands of miles away. This lesson will explore the positive and negative effects of globalization, focusing on the students’ place in a world that faces tremendous environmental challenges and is changing extremely quickly.
Global Climate Change
Published in
One of the most hotly discussed issues today is that of global climate change. The vast majority of scientists across many fields agree that the world is changing rapidly and that the effects can be seen everywhere. These lessons will discuss address the suspected causes of this problem, but will focus more on current research (using first hand sources when possible) into the adverse impact the change is having on various ecosystems and communities.
Humans in the System
Published in
Humans unavoidably have an impact on the environment and are part of the Earth’s systems; unfortunately, often we create problems in these systems, regardless of whether our intentions are good or not. This provides an overview of infrastructure in modern societies (transportation, waste management, energy, food production, product packaging, etc.) and how each uses natural resources and/or impacts the environment.
Niu's Camera
Submitted by Evan on Wed, 09/03/2008 - 4:49pmPublished in
The new Niu ocean drifter devices that we will deploy this year will have a digital camera! The camera will have a fish-eye lens, so it will provide a really cool, wide field-of-view. Because of the optics of this type of lens, most of the focus will be on objects close to the camera. What do YOU think will show up in the photos that Niu takes? Can you think of any creative projects that we can do with all those photos?
Tracking Leatherback Turtles
Submitted by Evan on Sun, 07/13/2008 - 7:00pmPublished in
Stanford University recently published an interesting story on using satellite tags to track leatherback turtles in the Pacific Ocean. The story, "Leatherback turtles’ route may offer roadmap to salvation" can be read here.
What do you think we can do to help protect leatherback turtles and other sea turtles?
