World's First Osmotic Power Plant Goes Online in Norway
The process, called osmotic power, is a harvesting the energy that appears when salt water and fresh water meet through an osmotic filter. For the moment, the project is small-scale but could prove the great potential of osmotic energy.
Amazing Experiment Creates 3D Self-Folding Solar Cell Around Water Droplet
University of Illinois researchers discovered a method to manufacture three-dimensional, single-crystalline silicon solar cells from thin films. They used photolithography and a process driven by capillary interaction that made the micron-thick film to bend around itself.
Solar Heat Powered Machine Turns CO2 Back Into Fuel
This is the simple description, of course - the machine, made of a metal cylinder, is called the CR5 (Counter Rotating Ring Receiver Reactor Recuperator) is working on the principle that heat triggers a thermo-chemical reaction in an iron-rich composite material.
Korean Scientists Find Quick and Easy Way to Produce Bio-Plastics
Petroleum stands at the base of every plastic we usually find on today's market. Polymers are everywhere, and if petroleum resources are about to go scarce with time, it's a good idea to replace it with other renewable and biodegradable material that we could use just as well as we use petroleum today.
Interesting and Easy to Build Solar "Sandwich" Makes Efficient Use of Space
I have just received a comment on one of my articles this afternoon from a certain mr. Ryszard Dzikowski, who presents his innovation I call "solar sandwich", consisting of two Gratzel organic cells, faced one another, and covered by reflective layers on the sides, except for one, which is used to feed the aggregate with light.
New Polymer Synthesis Cuts Plastic Solar Cell Production Time by 50%
Their discovery drastically reduces the reaction time (99% faster). In the past, the reaction that took place in 48 hours, now only lasts 30 minutes and increases the average molecular weight of the polymer by a factor of more than three.
America's First High School Powered Entirely by Renewable Energy
The greenest high school ever built will conserve energy by using 36 wind turbines and solar panels in conjunction with a green roof and systems that maximize the use of ventilation and natural light.
Saltworks' New Desalination Technology Uses 70% Less Energy
Saltworks Technologies reported that they can produce 1 cubic meter of fresh water using just 1kWh compared to 3.7kWh per cubic meter achievable using reverse osmosis.
Plastic Solar Cells with LEDs Offer Cheap Lighting in Poor Countries
According to a study, there are about 1.5 billion people in developing countries who do not have electricity, the majority of them using kerosene lamps for light after sunset. But now, thanks to the researchers from Denmark, the lighting problem could disappear.
BACS: Biodegradable Packaging Fabricated by Bacteria
Today's civilized society sometimes uses weird ways of doing things, like packing software serial numbers in cardboard or a lot of plastic. A project, named Bacs, is using bacteria to make an interesting cellulose material for green packaging.
