In most of the under developed nations, access to basic health care is scarce. A heater is an indispensable device for many applications, especially for medical purposes. As such, a simple and easy to make heater from readily available materials becomes valuable equipment to help alleviate the human health problems. An ultra low cost (total cost including materials and manufacturing is less than a dollar per heater) heater from readily available materials like paper/cellulose acetate sheet and a pencil was designed and fabricated. Manually, using high graphite contained pencil; paper/cellulose surface was arbitrarily coated by applying numerous pencil strokes ...
Daylight optimizer is self-adjusting roof panelling technology to maximize (or optimize) the amount of day-lighting throughout the day inside a building.
The science of daylighting design is not just how to provide enough daylight to an occupied space, but how to do so without any undesirable side effects. Beyond adding windows or skylights to a space, it involves carefully balancing heat gain and loss, glare control, and variations in daylight availability. For example, successful daylighting designs will carefully consider the use of shading devices to reduce glare and excess contrast in the workspace. Additionally, window size and ...

Renewable energy challenge
(From solar thermal energy to electrical energy)
This challenge is an individual idea to use 100% sustainable energy source to provide 100 % renewable energy.
This idea is based on the use of the solar heating system consisting of thermal heat collectors of a certain area that can provide adequate thermal energy to produce a pressurized steam, that in turn will press over the water surface confined in a pressure vessel to pump it up to a higher level tank, giving the the water an increase in its ...
Environmental issues including ozone layer depletion have become a significant issue because of vanishing natural resources and CO2 emissions according to sustainable use of fossil fuels during industrialization processes.
The Vertical Axis Waters Turbine (VAWT) is a device, simple in construction and which gives an appreciable output. Using water resource to produce electricity is a perfect option. But due to complexity of design and initial costs and also absence of a good design for a small scale energy production the small scale water turbines are not used. One of the biggest disadvantage of water turbines is that ...
Today the world's population continues to grow, so does the amount of garbage that people produce. Today's fast lifestyle requires easily disposable products as soda cans or bottles of water etc. The accumulation of these products has led to increased plastic pollution around the world. Plastic is composed of major toxic products has the potential to cause a great harm to the environment in the form of air & land pollution. Some plastics are manufactured from recycled material but their use in engineering tends to be limited because the consistency of formulate & their physical properties tend to be less ...
Recently the regulation of engine exhaust gas is more and more tight and in electricity generation industry gas engine is more and more promising instead of turbine using liquid fuel and diesel engine. Because gas engine using natural gas has advantage of stable supply and low exhaust harmful gas, the demand of gas engines rapidly increase in electricity generation industry.
I think the adoption of gas engine is best to overcome the problem of air pollution, high price of oil and shortage of oil. Specially shale gas boom rises in USA, Canada and so on. In the long term ...
The Hyper4 (a 4 stroke, 4 cylinder engine) improves the fuel efficiency of internal combustion engines by up to 75% (as reflected by Simulink Matlab and Converge CFD modelling software), approaching 50% brake thermal efficiency in a unique, compact axial design that is both straightforward and inexpensive to manufacture. Unlike a standard inline engine, the incorporation of Constant Volume Combustion, Variable Compression ratios and Over expansion is virtually effortless. These fuel saving strategies are well known, researched and documented but are extremely difficult to implement in a crankshaft controlled engine. The configuration allows for the inclusion of rotary valves ...

In recent years, it was discovered that the power of the sun can be collected and stored, to be used on a global scale with the purpose of eventually replacing the conventional sources of energy. As the world is turning its focus to cleaner power, solar energy has seen a significant rise in importance.
SolaVi project is based on an airplane with superior flight characteristics and outstanding structural integrity that has the ability to recharge during flight. The conventional method today uses fuel for aviation. The sustainable method is to use solar cells to collect the radiation and ...
ZERO-WASTE ZERO-CARBON BUSINESS-MODEL (ZW-ZC-BM)
[A Quadruple Impact Development (QID) paradigm that simultaneously answers the twin-problems of Global Warming and Poverty (GWP)]
THE PROBLEM: Global Warming and Poverty (GWP) are corollary in that both are simultaneously increasing due to the same basic cause: Wastage and Over consumption by the minority who control almost all human resources and governance. The disparity is such that about 15% of the population enjoy 85% of world GDP; and the balance 85% are able to enjoy just 15%. Further as this disparity is continually increasing due to the “richer” class wanting to overs end and ...

Standards continue to evolve on lower emissions for internal combustion engines, based on technology advancements and regulatory requirements. Adopting best practices and following manufacturer guidelines on ethanol fueling will further help reduce damage to equipment and the environment.
The RIGHT MIX STRIPS™ are rapid and simple to use test strips; they detect ethanol percentage levels in gasoline, that is commonly used in two-stroke and four-stroke engines. The test is conducted by immersing the end of the strip in a sample of fuel and obtaining the result from the position of the ethanol line, which moves up the strip ...
