Stanford scientists have developed featherweight, pliable batteries and supercapacitors in the form of everyday paper.

By coating a sheet of paper with ink made of carbon nanotubes and silver nanowires, the scientists were able to construct a highly conductive storage device that’s both low-cost and high-performance.

(The difference between a battery and a capacitor, you ask? both hold energy to be converted to electricity, but capacitors hold it for a shorter period of time. On the other hand, they can store and discharge energy much more rapidly.)

The batteries are so strong that you can crumple them and the performance does not degrade.Led by assistant professor of materials science and engineering Yi Cui, who previously created nano-size batteries using plastics, the researchers developed a solution that is more durable than conventional batteries.

A new biodegradable battery made of cellulose promises to offer thin, flexible, lightweight, inexpensive and environmentally-friendly batteries made without metal parts.

The battery is made from green algae known as Cladophora, found along freshwater beaches around the world.

The key to the battery’s success is its large surface area. Made from algae-derived cellulose with 100 times the surface area of the cellulose found in sheets of notebook paper, the battery can manage far more conducting polymer than in previous incarnations.

That means better recharge, hold and discharge capabilities.

The Danish island of Samsø has become one of the first industrialized places on Earth to qualify as completely energy self-sufficient.

The tiny island — just 30 miles long and 15 miles wide — first began its push toward sustainability in 1997. In just over a decade, Samsø erected 21 electricity-producing wind turbines and a heating system fueled by wood chip- and straw-burning furnaces accompanied by several small solar panels.

Eleven of Samsø’s turbines are onshore and ten are offshore; all generate one megawatt each. The onshore turbines produce more electricity than the island consumes — enough to offset 690,000 gallons of oil — while the offshore turbines produce enough power to handle the island’s transportation energy budget.

Award-winning environmental filmmaker Barbara Ettinger’s latest documentary is about a topic so obscure that even some COP15 attendees haven’t heard of it: ocean acidification. But it’s also a topic of critical importance that threatens human survival. The film, A Sea Change, follows Ettinger’s husband, Sven Huseby (the co-producer of the film and a retired history teacher) in his quest to discover what’s happening to the world’s oceans. He finds that global warming is just part of the problem.
