My city banned plastic bags — now where am I supposed to recycle them?

Q. Dear Umbra, Olympia recently banned plastic bags, which is great. Here is my problem: Now that stores are not using plastic bags, they have removed all the plastic bag recycle bins. I looked up places to recycle plastic bags in my area, and Lowe’s was listed. I took the bags I had been saving for six months to Lowe’s and they informed me that they would take the bags, but they are not recycled. The plastic bags just are thrown in their garbage. So I am back at the beginning again, trying to find somewhere to recycle the plastic bags that I have saved. Can you help me find somewhere that I could send these formerly recyclable plastic bags? Brooke W. Olympia, Wash. A…

On soft ground? Tread lightly to stay fast

Soft steps and large feet can allow animals and robots to maintain high speeds on very loose soil and sand. These findings offer a new insight into how animals respond to different terrain, and how robots can learn from them.

3D Printed Solar Energy Trees

Energy Inventions | Future Technology | Photovoltaic Cells | Solar PowerHow would nature do it? Researchers at the VTT Technical Research Centre of Finland may be discovering the answer, thanks to advancing solar and 3D printing technologies. They have developed some very decorative prototypes of what they are calling “energy harvesting trees”. The tiny leaves generate and store solar energy and can be used to […]

Seeing where energy goes may bring scientists closer to realizing nuclear fusion

An international team of researchers has taken a step toward achieving controlled nuclear fusion — a process that powers the sun and other stars, and has the potential to supply the world with limitless, clean energy. The team developed a new technique to ‘see’ where energy is delivered during fast ignition experiments and improve energy delivery to the fuel target.

Superoxide gives lithium-air batteries a jolt

In a recent experiment, scientists were able to produce stable crystallized lithium superoxide instead of lithium peroxide during battery discharging. Unlike lithium peroxide, lithium superoxide can easily dissociate into lithium and oxygen, leading to high efficiency and good cycle life.

Solar water splitting: Putting an extra ‘eye’ on surface reactions that store sunlight as fuel

Water-splitting cells absorb sunlight and produce fuel. Creating such cells means pairing a material to absorb sunlight and generate electrons with the one that uses those electrons to produce fuel. Scientists introduced a novel way to study the flow of electrons where the materials meet.

Physicists come up with a way to make cleaner fuel cells

An international group of scientists has developed ion-exchange synthetic membranes based on amphiphilic compounds that are able to convert the energy of chemical reactions into electrical current. The new development could potentially be used in fuel cells, and in separation and purification processes.
