Microbial Fuel Cell Could Propel Navy Ships for Years, Feeding on Sea Microorganisms
The microbial fuel cell is meant to use naturally occurring fuels and oxidants in the sea to power ships, replacing batteries and fossil fuels.
Danish Hotel Gives Free Meal to Anyone Cycling for 15 Minutes in Their Gym
While pointless as a way to really change something in the course of pollution reduction, a Danish hotel found a way to both motivate their customers to go green by pedaling and give them a free $36 meal voucher.
Puffin Personal Air Vehicle – Designed by NASA, Powered by Electricity
Any resemblance between the machinery on the right and the puffin on the left? None? Well, there may be some resemblance, considering their sizes - almost anybody wouldn't see them flying... but they do.
Nissan Plans to Recycle Old EV Batteries to Wind Power Industry
To greenify their car-supported existence, Nissan has taken the decision to recycle all the old batteries from electric cars by giving them to wind farm developers - of course, at a low price.
Future Solar Cells Made of Bismuth Ferrite Could Yield Higher Voltages
Scientists from the Lawrence Berkeley National Laboratory found a way to use a ceramic material made from bismuth, iron and oxygen (bismuth ferrite) to fabricate solar cells in a fashion that nobody ever tried to do. They even have results yielding high voltages out of their material.
36.1 Percent: The Most Efficient Solar Panel Made by Delaware Researchers
Their system consisted of a lens, a dichroic mirror, and two two-cell stacks sponsored by the NREL (National Renewable Energy Laboratory), achieving probably "the highest efficiency yet measured for the experimental conversion of sunlight to electricity by any means."
60 Year-Old, World's First Semiconductor Solar Cell Found in UK Antique Store
The contraption has been found in the UK, somewhere in Surrey, by antiques dealer Fred Nickson (owning Chiltern Antiques in Henley-on-Thames, Oxfordshire), who bought it from a distant relative of the builder, who is still unknown.
Rice Husks Making Cement Become Less Of a Polluter
Cement is made by heating limestone with clay at high temperatures, and is responsible for 5 percent of the global carbon dioxide emissions, with a ton of CO2 released for every ton of cement produced. To reduce that figure, a team of researchers from the University of Dundee in UK, developed an environmentally-friendly cement made of waste organic materials, such as rice husks.
NREL Researchers Using Solar Cell Technology for More Efficient White LEDs
Researchers from the National Renewable Energy Laboratory (NREL) have demonstrated they can produce white light by first making a yellow-green LED, and then combining it with other colored LEDs.
DIY: How to Make a Solar Cell at Home From Readily Available Stuff and…...
A very neat experiment that anyone with some skills can do in the garage or kitchen is creating a solar cell out of blackberry juice and titanium dioxide (and several other components).
