Nice new method in producing Q-Dots which seems to be more cost effective, efficient and reliable.
Large-scale technique to produce quantum dots.
A method to produce significant amounts of semiconducting nanoparticles for light-emitting displays, sensors, solar panels and biomedical applications has gained momentum with a demonstration by researchers at the Department of Energy’s Oak Ridge National Laboratory.
Using the power of nano to solar power our homes at night.
MIT researchers have built a new experimental solar cell which could greatly enhance power efficiency. The “Shockley-Queisser’ limit is the estimated maximum efficiency of a solar cell, which is commonly about 32%; that means almost 70% of energy is wasted in the form of heat.
One way to reduce energy loss is by stacking cells. However if sunlight could be turned into heat and then be re-emitted as light, the solar cells could utilize more energy. Solar cells work best with visible light which occurs midway of the radiation spectrum. As a result the radiations with shorter and greater wavelengths usually go to waste.
The researchers at MIT have developed a structure of carbon nano-tubes that will function between the sun and solar cell. These carbon nano-tubes are very good absorbents of light (all types of radiation) and convert it to heat; heat is easier to store unlike light.
Got to luv this.
Is this brand new type of battery the key to clean energy and off-grid electricity?
Lithium-ion batteries are having a moment. After becoming the de facto battery in laptops and cell phones over the years, they’re now starting to power electric cars (like those made by Tesla) and plug into the power grid.
But lithium-ion batteries aren’t the only battery type in town. Some brand new battery varieties could actually be more promising than lithium-ion when it comes to storing energy generated by solar panels or used to power remote villages in Africa, India, and Asia.

Urban Produce High Density Vertical Growing System is a patented technology that was developed taking advanced hydroponic technology and automating it. Urban Produce has the capacity to grow 16 acres of produce on 1/8 of an acre with just one of it’s High Density Vertical Growing Systems. Our mission is to build our patented systems across the U.S. to provide both locally grown sustainable produce to Urban Cities while also stimulating the local economies. We are 21st century growing! www.urbanproduce.com

By 2050, the world will need to feed an additional 2.5 billion people living in cities. Yet as the demand for food rises, the amount of land available for agriculture in developed countries is expected to decline. In Japan, at the Fujitsu factory of Aizu-Wakamatsu which still manufactures semiconductor chips for computers, a different project is underway which may offer a solution to this problem. The company has converted an unused part of the factory into a farm to grow food — and more specifically, to grow lettuce. Fujitsu has focused on growing a low-potassium variety, which is sold to people with kidney problems who cannot process the mineral properly. Join Rachel Mealey in Japan’s Fukushima Prefecture to visit the sun-free and soil-free urban farms of the future.
Food deserts, lack of arable land, and the frozen months of winter are all obstacles we face in our mission to keep people fed. Urban Produce is excelling in this mission by licensing its patented indoor vertical farming technology, which can produce 16 acres of organic, leafy greens in just 1/8 acre of space.
