As a Photovoltaic cell gets hot its ability to convert sun-light to electrical energy reduces. This increase in temperature occurs as a simple byproduct of exposure to the light of the sun. For solar arrays that don’t use collectors, the temperature increase is minor. But as collectors are used to concentrate the solar radiation on a smaller assembly of cells, the temperature increase becomes substantial.

At present, attempts to control this temperature increase involve placing the cells in cooling towers mounted to the collector, or to use water as a cooling medium. Towers increase air flow past the cells, using convective cooling to reduce temperature build-up. Water simply replaces air as a cooling medium to assit in heat transfer ...

Solar Panels offer one of the most sustainable and clean forms of energy. Substantial progress in developing cell technologies has both raised the efficiency of the cells and lowered their cost. However, solar is still facing barriers that prevent it from becoming a viable alternative to fossil fuel. We have a solution that increases performance and lowers cost further by addressing aesthetic and installation issues.

Our low profile Micro-Strip design uses a linear array of conventional solar cells that are placed on an angled surface that can be glued, screwed and bolted to existing structures. A low cost and easy to fabricate metal or plastic mounting is attached in the factory to a strip of cells and then ...

The use of proposed technology of Modeling of Intelligent Systems Thinking in Complex Adaptive systems is oriented on use in autonomous, intelligent Fuzzy Control and Information Complex Adaptive systems, that operate in real-time, fuzzy conditions, heterogeneous subject areas and multilingual communications, there the situations are unknown in advance, fuzzy structured and not clearly regulated. The technology consists in extracting of relevant data, information and knowledge from texts (speech) in various natural languages, within dissimilar subject areas for implementation of fuzzy control of data, information and knowledge in light of representing them in knowledge bases and organizing on basis of them the processes of Reasoning and Systems Thinking under uncertainty and in Fuzzy Environment. The technology is formalized using Fuzzy ...

This device uses manufactured containers which are connected via a modular connecter to heat fluids with solar energy. In essence, you reuse containers, connect them in series, and utilize the sun to provide heated fluids. There is energy saved by reusing normally discarded containers, and there is energy saved by utilizing the Sun for heating fluids. It is an optimal saving solution for a basic human need.

It is a perfect solution for seasonal needs such as heating pool water, or as a heater or a preheater for a hot water heater. Combined with a pumping source, it can be used for all types of water heating needs. A basic system has a pump, connecting lines, containers, ...

Molten salt solar water purification plant is an idea to utilize untreated water available, to convert it into drinking water.

In the developing countries many villages are not connected to central water distribution plant and people living there rely on local water body. Due to lack of grid and other resources the water is not treated and people have to use local and ad hoc methods to get clean drinking water and have to fetch water form distance.

Due to dissolved fluoride and other heavy salts hand pump water are not fit for drinking and cooking that water can also be treated with this system.

In the proposed idea, water is evaporate using solar thermal energy and condensed and ...

For decades the scientific world has been dreaming of building enough 100 Megawatt OTEC (Ocean Thermal Energy Conversion) power plants to fill the oceans. Why not take the power from the world’s largest solar collector (the ocean)? Near the equator, the warm water provides power to generate electricity, while the deep cold water can condense the working fluid (refrigerant). But the energy required to pump the cold water up 1,000 meters makes the plants expensive and inefficient.

A conventional 100 MW OTEC plant requires about 222 cubic meters of cold water/second to be pumped up to the OTEC plant. That requires huge pipes and lots of power. Recently a new OTEC design was filed for a patent application, and ...

Thailand wind characteristic is unstable with minimum speed about 2 m/s and maximum speed about 5 m/s.

At high wind speed, wind turbine blade is sharp and thin. On the other hand, at low wind speed the blade is long and more area.

My design is to innovate the blade that can change its shape to create the most efficient windmill not only in low speed but also high speed.

Shape memory alloy (SMA) is alloy that remembers its original shape and that when deformed return to pre-deformed when heat or change temperature.

First we apply the property of SMA, sheet from SMA. At low wind speed ,the morphor wind ...

Recent analysis indicates that more people around the world have access to a mobile phone than a toilet. Although, having access to a mobile phone is not a bad thing, what it simply indicates is that people seem to use cutting edge technologies without having access to basic amenities. An estimated 2.5 billion people lack access to clean and safe bathrooms/toilets, resulting in diarrheal diseases that kill more children than AIDS, malaria, and measles combined. Many developing country governments simply do not have the financial or human capital to deliver improved sanitation to their citizens equally. Furthermore, many development programs that strive to provide sanitation often fail to have the impact and sustainability needed to scale, and instead distort ...

This is a new method of manufacturing thin multi-crystalline Silicon photovoltaic cells.
The method involves a centrifuge that is able to run efficiently at the melting point of silicon. The size of the centrifuge is about 12" in diameter and approximately 15" in length. It spins at fairly low speeds on a horizontal axis. The centrifuge is heated from the inside with a moveable carbon based heater. It runs in a near vacuum. A carbon 'boat' measuring about 1.1" wide x 13" long by about 0.010" thick with part of the middle of the strip milled out to a depth of about 0.007". Some molten Silicon is deposited into the 'cavity' where it immediately hardened and grip the carbon ...

Historically, a long time before quantum mechanics, Lorentz suggested that some disturbances, like waves, could be transmitted with traveling particles through a certain medium without moving it. At that time, instead of careful analysis of the systematic errors, some scientists chose to postulate constancy of the light velocity to explain why the earth appears not to rotate around the sun in the Michelson experiment. Mathematically, it was based on the Lorentz transformation that preserves a wave equation in the moving frame instead of time invariance in the Galilean transformation. Since it equally applies to any wave motion, the anisotropic values of the velocity of light are used in Einstein's original manuscript and all applications, e.g. a global positioning system ...
