Finally, here is the solution to the world's requirement for power, with no carbon footprint, and no more need of fossil fuels! This new-technology electricity generator functions uniquely according to known principles of electromagnetic induction, and requires no external power or fuel, and is patented (US 8,847,720). The power output depends upon the frequency of the inducing current, making a very small generator extremely powerful. It is modular and scalable; as there is no fuel, there is no danger of fire or explosion, and there is no carbon footprint. Having no moving parts, practically no maintenance is required.

A DC to AC switch used has a maximum of 780,000 cycles per second, compared to 180 cycles per second in ...

Gridlock in and around megacities is already at crisis levels and will escalate exponentially into the future unless viable solutions are found to solve the problems. Pollution from idling motor vehicles aggravates global warming problems.

Mega cities which border on waterways have a solution which is immediate and much less expensive than other proposals which would take decades to implement The judicious use of hovercraft on waterways offers a solution which can be implemented now and show positive results within a remarkably short period of time.

The study we made was to do with Toronto (Canada) which has gridlock problems which have been estimated to accumulatively cost $11 BILLION a year.

The Lake Ontario shoreline is underutilised and hovercraft ...

Aero Vitae is a system to solve the interconnected issues of air quality and water purification. We propose using a cascade system of organic digesters and aeroponics to directly dispose of city waste water and airborne particulate. Indirect benefits will be a local cooling effect and oxygen enrichment.

The first stage will be similar to normal water treatment, the separation of the solids from the waste water. The solids will first be treated in a high efficiency methane digester, which will be used to provide a high grade fuel for the facility, and general electricity. After the majority of digestion has been completed the solids will be partially re-hydrated, and passed onto the first aerobic stage: ...

Need of energy is constantly increasing because of increase in population and industrialization globally. Depletion of fossil fuel, increase in pollution level and imbalance in the ecological level of the earth, etc. cause researchers to think of alternative solutions to fossil fuel. Biodiesel derived from crops may be replacement of petroleum-derived fuel used for transport and power generation without adversely affecting the crisis of food and also keeping the environment clean. This research talks about algae cultivation, process for algae to biofuel conversion, conceptual design and general layout of slow pyrolysis process. B40 gives approximate 54% mechanical efficiency compared to B0 of 51% in an I.C.Engine. Thus algae biodiesel may address current burning issues of the country as well as ...

In the history of transportation, electricity has always replaced fossil fuels when a commercially viable technology was available. Historically, major manufacturers have invested in electric trains and cars and it’s clear that electric aircraft are next. However, none of the current solutions for electric planes provide engines that are adapted for large scale commercial flights. Whilst "Electric aircraft are a key element in our research for the future of aviation" as Airbus' CEO Tom Enders outlines, most efforts have focused on the classic "electromagnetic" engine for its incomparable efficiency. Yet current technologies do not offer sufficient power density for high speed flights. By applying arcjet technology to jet engines– i.e. heating air with an electrical arc instead of burning ...

Large wind blade surfaces embedded with flexible Solar Panel can generate more energy out of the same system. For example, Shrouded design type with flexible solar panel has been shown in the diagram. Depending up on the area of wind turbine blade either horizontal or vertical or shrouded, the same system can generate more power output.

Also, such systems’ tower can be installed in the shallow seabed. A fixed propeller can be attached in the tower with gears, while gears provide the ability to rotate. It is to harvest wave energy. This amalgamated design can harvest solar, wind & wave ...

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 on the surface. Contacts were connected using either a wire or Copper/Aluminum foils over the coated surface. Power was supplied ...

At present there are large number of high rise buildings in modern cities. The glass windows in these modern architectures require constant cleaning which is presently carried out using a gondola system, hanging from the building wall.Glass cleaning of high rise buildings is becoming one of the most demanding field for automation because of high level of difficulty faced by the workers and presence of their safety risk.

The development of my project offers a novel alternative solution to the above mentioned problem by providing and developing an intelligent unmanned cleaning system which can be used on different buildings.

The "Automatic Glass Cleaning Machine" is an unmanned semi automatic machine used for cleaning the entire exterior surface ...

Pollution is the major problem in the universe, air pollution being one of the predominant among them. Air pollution is mainly caused due to the exhaust gases coming out of the vehicles and industries. This is caused mainly due to burning of fuel and gases emanating from chimneys. In an effort to control this pollution, a combination of bio-degradable materials has been selected to absorb major pollutants namely Carbon Dioxide (CO2), Carbon Monoxide (CO), Sulphur Dioxide (SO2) and Hydro Carbons (HC) from automobile vehicles.
Applications: Artificial trees ,industrial pollutants ...

Battery Maximizer is an intelligent, non-intrusive device that clips on the terminals of a rechargeable battery and tells the user its Remaining Battery Life (RBL) by an inbuilt impedance analyzer that continually evaluates the battery’s internal chemistry. It provides consumers with accurate information regarding expected battery lifetime. It reduces the chances of unforeseen battery failure and the numbers of batteries that are prematurely discarded before they fail. As a result, the demand for battery production and correspondingly disposal can be under much better control.

Australia imports annually 7.6 million automotive and industrial battery units and at the same time 6.9 million units are disposed of. Among the disposed batteries, it is estimated that 20% end up in landfills while 33% ...
