Super Solar Storage to Revolutionize Sustainable Energy

Getting renewable energy is the easy part whereas storing it is the hard part. Battery technology has not kept pace with the green technology field. That is until a team at MIT figure out how to store sweet savoury solar energy efficiently.

Until now, solar power has been a daytime-only energy source, because storing extra solar energy for later use is prohibitively expensive and grossly inefficient. With today’s announcement, MIT researchers have hit upon a simple, inexpensive, highly efficient process for storing solar energy.

Requiring nothing but abundant, non-toxic natural materials, this discovery could unlock the most potent, carbon-free energy source of all: the sun. “This is the nirvana of what we’ve been talking about for years,” said MIT’s Daniel Nocera, the Henry Dreyfus Professor of Energy at MIT and senior author of a paper describing the work in the July 31 issue of Science. “Solar power has always been a limited, far-off solution. Now we can seriously think about solar power as unlimited and soon.”

Inspired by the photosynthesis performed by plants, Nocera and Matthew Kanan, a postdoctoral fellow in Nocera’s lab, have developed an unprecedented process that will allow the sun’s energy to be used to split water into hydrogen and oxygen gases. Later, the oxygen and hydrogen may be recombined inside a fuel cell, creating carbon-free electricity to power your house or your electric car, day or night.

Mariners Know How to Cook – and Clean!

When out at sea one must make the most of what one has, so chefs are put into a situation in which they need to ensure all their cooking gear and serving gear survives rough seas. It’s lucky for us that they have shared their tips for keeping equipment clean and in ship-shape! These tips are good for anyone who uses a kitchen!

Dishes or Plates:

Cracked: For hairline cracks, put the plate in a pan of milk and boil for 45 minutes. The crack should disappear: if not, it was probably worse than you originally thought.

Greasy: Soak in hot water with baking soda. Chemically, baking soda plus grease equals soap, not soap to wash the baby mind you, but soap just the same.

Smelly: Wash them in salty water, or use a little ammonia in hot soapy water. You can also add a little ground mustard to the water.

Stained: Soak overnight in a mixture of hot water and soda. Then rub in a vinegar moisten cloth dipped in salt. This works very well with tea stains.

Energy for All, All the Time!

Today I just want to remind readers that there is indeed enough renewable energy out there to power the needs of humanity on the planet. In fact, wind, solar, and other renewable power sources can provide enough energy to power us and have extra juice to spare.

The shift from our current fossil fuel based economies to sustainable renewable energy economies is usually presented as a great challenge. That is also the message coming from the UN Climate Conference in Copenhagen. Oil companies tell us that it can be done but that we need decades to get there. The numbers tell a bit of a different story. Total world energy consumption is about 15 terawatts (2005). All that energy can be generated by today’s solar panel technology on a sunny piece of land of about 550 by 550 kilometers (340 square miles). That is for instance about 3% of the surface of the United States and China, 4% of the surface of Australia, 3.5% of Brazil and 9% of India. And we just need to capture about 20% of the solar energy that hits such an area. Of course the beauty of solar energy is that it can be generated locally. So we are not going to see such a centralized production. But the numbers clearly convey that the challenge is not as huge as it is often presented.

Pollution Dress is Stylin’

A fashion designer has made a dress with a CO2 detector in a dress then lights up using LEDs depending on the concentration of CO2 in the area.

The Climate Dress is made of conductive embroidery, over hundred of tiny LED lights inserted into the embroidey, a CO2 sensor and an Arduino Lilypad microprocessor. The LEDs visualize the level of CO2 in the nearby surroundings and are powered trough the embroidery!
For The Climate Dress we used soft conductive thread that has a similar consistence to the kind of thread used for traditional and industrial embroidery production. This way it is possible to make embroidery that become more than an esthetical element in clothing and interior textiles.

The embroidery becomes functional conveying electricity and computer information and thereby give “power to the dress”. The dress senses the CO2 concentration in the air, then accordingly creates diverse light patterns varying from slow, regular light pulsations to short and hectic. The technology, which integrates ”soft circuits” into the production of embroidery, is an innovative process. It is the result of a fruitful collaboration between Copenhagen based design studio diffus, Swiss embroidery company Forster-Rohner, the Danish research-based limited company Alexandra Institute and finally the Danish School of Design.

How California Tracks the Air That They Breathe

California has a law that dictates the quality of air, but that needs to be tracked so it can be enforced. Here’s a video about how Berkeley Lab keeps track of the air.

Last March, Lawrence Berkeley National Laboratory scientist Marc Fischer boarded a small airplane loaded with air monitoring equipment and crisscrossed the skies above Sacramento and the Bay Area.

Instruments aboard the aircraft measured a cocktail of greenhouse gases: carbon dioxide from fossil fuels, methane from livestock and landfills, nitrous oxide from agriculture, and industrially produced gases such as refrigerants.

The flight was part of the Airborne Greenhouse Gas Emissions Survey, a collaboration between Berkeley Lab, the National Oceanic and Atmospheric Administration, and the University of California, Davis to pinpoint the sources of greenhouse gases in Central California.

The airborne survey is intended to improve inventories of the state’s greenhouse gas emissions, which in turn will help scientists verify the emission reductions mandated by AB-32, the ambitious legislation passed by California in 2006 to slash the state’s greenhouse gas emissions 25 percent by 2020.

“In order to comply with AB-32, we need to know where the gases are coming from and how much,” says Fischer, a scientist in Berkeley Lab’s Environmental Energy Technologies Division.
