Water scarcity and desertification are well-known problems for the poorest regions of the world. Atmospheric water generators could provide the solution, but they are complicated, expensive and they need additional energy for operation.
For the critical regions the requirements are defined by the lack of money, material and infrastructure:
- no unique/dangerous materials
- simple design
- no moving parts
- no maintenance
- no extra energy
- easy to manufacture (handmade)
- long and safe operation
The idea is to merge the adsorption chillers and the atmospheric water generators using the sunlight and the big temperature ...
The aim of the project is to show that applying additional renewable energy sources, e.g. wind turbines and photovoltaic cells, for supplying the elevator drives and auxiliary circuits (control and illumination) leads to considerable reduction of operation costs and increases the reliability.
This new solution, together with the Supercapacitor based Energy Storage Systems (SESS) providing for energy recovery at lifts/elevators, has a huge market potential. There are about 5 milion elevators in the European Union. It requires 18,4TWh of energy per year. New York City does have 65,000 elevators that the City Department of Buildings estimates make approximately 30 ...

Current problem to solve:
In the current situation of growth of CO2 emissions to the atmosphere, and other pollutants NOX, due to the combustion of fossil fuels for transport such as cars using the environment in cities can become unbearable, causing respiratory problems for the population, which sometimes must wear anti-pollution masks because particles suspended in the air. This is a problem that should be more focused on the source of it, which put remedies to its effects. The problem of deforestation and the growth of cities fouls the air, which is not renewed and community life difficult. My ...
The efficiency of solar cells depends, among other things, on the angle between the sun and the solar cell. The efficiency of such solar panel can be thus increased by tracking the sun path and minimizing the angle of incidence. Nowadays, similar systems are actively controlled by coupling sensors, computer and a motor which tilts the cells towards the sun which, in turn, consumes the part of gained energy for tilting the panels.
Solution proposed here presents a passive system which is based on the sun direction and uses no additional power source to follow the sun ...
Conventional Overbalanced Wheels that are famous for perpetual motion machine do not rotate. Now, I disclose new Machine. Figure 1 shows new Perpetual Motion Machine that generates rotational energy by using a Capillary and a Wheel including a Sponge and Weights.
The Capillary shown in figure is made with a microfiber or a capillary tube. The Capillary lifts Water by capillary action. A Microfiber hangs from top of the capillary. Twelve Interspaces are formed along outer periphery of the Wheel. A Weight is placed in each Interspace.
A Sponge is further provided along outer periphery of the Wheel. For ...

Some people love to garden and grow their own food. Growing your own vegetables makes you sure that what you consume is safe from insecticides or any chemicals applied to make it look fresh for longer time. Gardening also helps in making the environment clean and beautiful.
Unfortunately, people who live in urbanized community doesn't have enough space for gardening to grow their own plants/vegetables. This idea may help to solve that problem. The garden box can be stacked by layers to maximize the space so that more plants can be grown. It can be easily installed in rooftops ...

This system uses air pressure vented unto an impeller to cause rotation of a re-designed electric motor with a hydraulic pump and electromagnetic clutch attached to the armature's drive shaft. The re-designed electric motor has an electromagnetic clutch that advances the field coil of the electric motor. The clutch will advance in the same direction as the armatures rotation and will slip as it is doing so. The hydraulic pump advances the pressurized fluid unto the second assembly causing the rotation of the field coil that advances the pneumatic turbo compressor. The turbo compressor is a centrifugal compressor. The ...

The use of alternate forms of energy are essential in the upcoming days as conventional sources cannot be preferred in future due to the uprise in Global warming. Solar energy is the energy obtained from the radiation emitted by the sun, this form of energy is free of cost,inexhaustible and reliable, it is used for water heating, drying and generation of electricity.
Only 4 percent of Earth's water is fresh or consumable and about 70 percent of water is covered in oceans and is non consumable.This design aims at filtering of saline water by solar energy by ...
The natural movement of the sunflower towards the sun can be used as a idea to track the solar energy efficiently. For this open software PSoC (PROGRAMMABLE SYSTEM ON CHIP) by Cypress is used. This tracker will rotate horizontally and vertically with the help of a motor system based on light dependent resistor towards the light.
The Maximum Power Point Tracking (MPPT) also used here which will help in efficient storage of solar charge in battery and distribute ...

Availability of clean water is a problem around the globe. Some remote areas have waterfalls that may be too small for power generation, but are high enough to use the head pressure to force water through a reverse osmosis system to supply clean water to a small village.
A long stand-pipe secured by ropes or tripod filled with reverse osmosis and/or carbon/sand filters could be erected in the flow of the waterfall with an output pipe running perpendicular out to a collection ...
