Solar-powered ATMs by Vortex

Solar-powered ATM Alternative energy can be a boon for third world countries. Normally governments have to invest vast sums of money in developing infrastructures for a long period of time in underdeveloped areas. If we consider the example of cell phones, they have bypassed the usual wires, poles, roads, telephone exchange infrastructures. People residing in remote villages can be connected via mobiles. Same thing can happen with ATMs (automated teller machines) too. Vortex Engineering is an India-based rural ATM manufacturer. State Bank of India (SBI) wants to deploy 545 ATMs across semi-urban and rural India. 1 Comment

Solar Energy from Plant Protein Structure

Plant Protein Structure Nanoscience is quite fascinated with the process of photosynthesis. They want to duplicate this process exhibited by green plants and utilize the solar power for energy use. Till now power generating solar panels are not in a position to replace the fossil fuels. They produce little amount of energy and quite expensive also. Generation of solar energy also depends on geographical locations. Deserts are more suitable locations for solar power than areas experiencing temperate climate. But we can have a new source of solar power that also delivered a power packed performance for us when it is on our dinner/lunch plate i.e. pea power. 2 Comments

Honda Solar Hydrogen Station Introduced to Green Car Market

Honda Solar Hydrogen Station Honda finally unveiled their new solar hydrogen solar station and all signs point to a dramatic success. The station is smaller than previous models and enables an electric car owner to refill their fuel cell overnight. The unit should easily fit into a homeowners’ garage taking up significantly less space than previous models. The older model required a compressor and electrolyzer for it to be operational. One of the reasons the units were so big was because of the compressor that was required to run the unit. Not only that, the compressor was also the reason that the units were so expensive to produce and purchase. 5 Comments

The Future is Now with Light-Powered Circuitry

Light-Powered Circuitry The brain of any electronic device is the circuitry that operated the machine. Without the circuitry, the device is not even worth the cost of the plastic that it is made of. Any electronics device requires some kind of battery or it is nothing more than a paperweight. Recently, some new technology was created by scientists from the University of Pennsylvania that will no longer require a device to use a battery as the power can come from light-powered circuitry. 3 Comments

Solar Cells from Tobacco Plants May Be a Reality Soon

Tobacco Plants As the world continues its quest to use less fossil fuels, the latest possible solution comes from the most unlikely of sources: the tobacco plant. This latest news comes from the University of California, Berkeley. It will be nice to see tobacco used for something other than lung cancer. This new discovery is based on the possibility of literally programming the cells of the plants to get solar cells from tobacco plants. The science behind it is actually pretty simple (at least in explanation form) and pretty amazing. By using a genetically engineered virus, scientists were able to literally transform the cells of the plants to create synthetic solar cells. 13 Comments

Self-Assembling Solar Cells

Self-Assembling Solar Cells What can a scientist do with salad dressing apart from telling you that it increases the taste of salad manifold? But that’s the beauty of this profession. As Newton could give some theories when he saw an apple falling from a tree, salad dressing can inspire scientists towards a brand new type of solar cells. The researchers managed to create a cheap, efficient and very simple method of making solar cells. The USP of these solar cells is that they self-assemble on a variety of substrates. The new technique draws parallel from the fact that oil and water don’t mix at all. Another unique fact is forces the elements of electronic components for example solar cells assemble themselves at the boundaries between the two types of liquids. This work was recently published in Proceedings of the National Academy of Sciences (PNAS). 7 Comments

New Solar Pond Distillation System

Solar Pond Researchers at the University of Nevada, Reno are developing a solar technique that will take care of the ecosystems of terminus lakes around the world. This new solar distillation system will help in removing the salinity of the lake water. This will be possible with the help of a specialized low-cost solar pond and patented membrane distillation system deriving power by renewable energy. Francisco Suarez is a doctoral student in hydrological sciences at the University. He is of the view, "These lakes -- hundreds worldwide -- such as the Great Salt Lake, the Salton Sea, the Aral Sea and Walker Lake here in Nevada, see a decline in water levels and an increase in salinity from both human and natural processes. The high levels of salinity are dangerous and unsustainable for aquatic life." 2 Comments

Solar Lamps Transform an Indian Village

Solar Lamp India Villagers of Wagharwadi till now knew how to make most of the daylight. This village is in Maharashtra, India. They used plastic plates as skylight. This kind of skylight helped women to recognize the ingredients stocked in their kitchens. After evening, villagers depended on candles and kerosene lamps. If some emergency or calamity forced to get some more light in the night they resorted to burning dry twigs. People living in the developed countries would find it a bit difficult to imagine such a situation. 7 Comments

Harnessing Solar Energy Outside the Sun Belt

Harnessing Solar Energy If we try to observe which states are going solar we will find an interesting bend. Many states in U.S.A. are not the sunniest one but still they are opting for solar energy. It’s natural for sunny California to go for solar energy. South Florida is a focus of solar activity because it enjoys a balmy weather and a progressive bend of mind. If we study the energy maps of parts of the Phoenix we will find that they are also opting for the solar energy. If we care to look into the demographics we will find that people want clean and green energy like solar energy while living in shady area. Why? The answer lies in the economic status. They have money to spend and possess progressive thinking. 14 Comments

High-Tech Thin-Film Origami

Thin-Film Origami You can think of it as origami -- very high-tech origami. Researchers at the University of Illinois are working on the same good old silicon but they are taking an entirely different route. They are working on thin films of silicon applying two processes one is photolithography and another is self-folding process driven by capillary interactions. This technique results in the three-dimensional, single-crystalline silicon structures. Their films are only a few microns thick. Their greatest strength is mechanical bendability that is not possible with thicker pieces of the same material. 2 Comments
