Artificial Trees to Harness Solar and Wind Energy

Planting trees is going to save the planet from global warming. And now planting artificial trees would help even more. Everything artificial doesn't have to be bad for Earth; a London based company called Solar Botanic intends to use Energy Harvesting Trees to generate solar as well as wind energy. The solution is unique in a sense that the same installation can use two alternative energy sources to produce clean electricity.
Biomimicry – that is an emerging science – is going to be used to implement some of the nature's processes in order to produce clean, environment friendly energy. The tree, once installed, will replicate the functions of a solar-wind harvester. According to the company's website, its energy capturing powerhouse is going to be "Nanoleaf". According to the Nanoleaves page, "A Nanoleaf is thin like a natural leaf, when outside forces, like the wind pushes the Nanoleaf back and forth, mechanical stresses appear in the petiole, twig and branches. When thousands of Nanoleaves flap back and forth due to wind, millions and millions of Pico watts are generated, the stronger the wind, the more energy is generated." "Due to the unique combination of photovoltaic and thermovoltaic in our Nanoleaves, it converts this thermal radiation into electricity, even hours after the sun has set," the page further states.

Of course the biggest benefit of such trees will be the availability of extremely nonpolluting electricity. But along with this, they will also eliminate the need to create eyesores in the form of gigantic wind turbines and solar panels. These energy harvesting trees will look as natural as normal trees. This is like growing gardens and mini forests that are actually silent electricity generators

MIT Geniuses Have Transformed Spinach Plants Into Bomb-Sniffing Machines
Engineers at MIT have transformed spinach plants into bomb-sniffing machines that can wirelessly relay warning signals to a handheld device similar to a smartphone.
They embedded the plants' leaves with carbon nanotubes–tiny cylinders of carbon that can detect "nitroaromatics"–chemical compounds often used in landmines and other explosives. When one of these chemical compounds is absorbed naturally by the plant (either in the air or through groundwater), the embedded nanotubes emit a fluorescent signal that can be read with an infrared camera, MIT said. "The camera can be attached to a small computer similar to a smartphone, which then sends an email to the user.

The results thus found open the door to the use of wild-type plants for infrared communication in wide areas, and real-time monitoring of environments such as cities, crop fields, high-security facilities, and homes.

Engineers Develop New Magnetic Ink to Print Self-healing Devices that Heal in Record Time
A team of engineers at the University of California San Diego has developed a magnetic ink that can be used to make self-healing batteries, electrochemical sensors and wearable, textile-based electrical circuits. The key ingredient for the ink is microparticles oriented in a certain configuration by a magnetic field. Because of the way they're oriented, particles on both sides of a tear are magnetically attracted to one another, causing a device printed with the ink to heal itself. The devices repair tears as wide as 3 millimeters–a record in the field of self-healing systems.

"Our work holds considerable promise for widespread practical applications for long-lasting printed electronic devices," said Joseph Wang, director of the Center for Wearable Sensors and chair of the nanoengineering department at UC San Diego.

Existing self-healing materials require an external trigger to kick start the healing process. They also take anywhere between a few minutes to several days to work. By contrast, the system developed by Wang and colleagues doesn't require any outside catalyst to work. Damage is repaired within about 50 milliseconds (0.05 seconds). Engineers used the ink to print batteries, electrochemical sensors and wearable, textile-based electrical circuits (see video). They then set about damaging these devices by cutting them and pulling them apart to create increasingly wide gaps. For example, nano-engineers printed a self-healing circuit on the sleeve of a T-shirt and connected it with an LED light and a coin battery. The researchers then cut the circuit and the fabric it was printed on. At that point, the LED turned off. But then within a few seconds it started turning back on as the two sides of the circuit came together again and healed themselves, restoring conductivity.
