Most ceiling fans run even when nobody is around! What if fans can sense that no one is in a room, slow down and switch itself off? Ceiling fans are static too. What if fans can swing right to left and left to right in a slow motion? Ceiling fans cut the air horizontally to make uneven gusts of wind. What if fans can pull the air above to make even gusts of wind? What if fans can project artistic patterns, words and numbers on the ceiling surface?

The ceiling fan is one of the most used electrical appliances in a house in India as well as in many countries around the world. It is estimated that there are ...

The global economy thrives on energy. Affordable energy directly contributes to increase productivity, reducing poverty and improving betterment of life. The global population is increasing day by day, which, in a way is leading to the utilization of natural resources and fossil fuels. Concentrating on the limited stock of fossil fuel, efforts have been in full swing to search for sustainable alternative to petroleum without adversely affecting the supply of food with keeping the environment clean (GO GREEN).

Biodiesel from algae is the most promising renewable biofuel derived from biomass with the potential to completely displace petroleum-derived fuel without adversely affecting the supply of food and other crop products, while keeping the environment pollution free. An alga grows naturally ...

Prior to AC all-magnet motors were used for some four decades then forgotten, perhaps from ferrites of the day too weak to be very practical while today with cobalts they are far stronger and last at 90% full power >>700-years.

A recent 1-Megawatt all-magnet generator was developed to have 'no spark', for security to provide power in with explosives and isolated from external needs, has a 50-year, 100%-Continuous Duty-cycle output guarantee with normal service.

A specific design for the Astrobotic M-1 Lander, became a novel geometry of all-magnet motors for electricity of 2.6kw, 110vdc, 24A, 18cm x 7.6cm in diameter replacing a 542w solar panel for use in space.

An advantage for in-transit being aiming with reactors no fuel, allows lunar night ...

ALPHA is a remotely piloted reusable rotary flying platform for launching spacecraft from high in the stratosphere instead of from the ground.

The first stage of a typical multistage rocket is essentially a flying launch pad for the second stage. As the largest and heaviest section of the rocket, the first stage lifts the second stage from the densest part of the atmosphere to extremely high altitude where flight conditions and requirements are very different. Then the second stage is launched and the first stage is usually discarded at great expense after only a single use. Some effort has been made to recover and reuse first stages, but these achievements are limited.

ALPHA is a better flying launch pad for the ...

Paint typically consists of pigment, resin, solvent and additives: Pigment - to provide colour, hiding and control gloss. Pigments are usually divided into two groups. One called 'Prime Pigments' includes pigments such as Titanium Dioxide (white), Chrome Green Oxide, Yellow and Red Iron Oxides. Waterborne paints most often use acrylic emulsion polymers as binders. These come in a wide variety of types and combinations. Common acrylic polymer types are based on monomers such as methyl methacrylate and butyl methacrylate. Traditionally, lower cost paints have been formulated on PVA (Poly Vinyl Acetate) binders. Solvent-based resins come in a very wide range of types. The most common solvent-based resins are termed ‘alkyd resins’ that are normally used in enamel paints. Urethane ...

An ambulance is a vehicle which can transport medical patients to treatment and in some instances will also provide out-of-hospital medical care to the patient. Ambulances are used to respond to medical emergencies by the emergency medical services.

For this purpose, they are generally equipped with flashing warning lights and sirens. They can rapidly transport paramedics and other responders to the scene, carry equipment for administering emergency care and transport patients to hospital or other definitive care. Most ambulances use a design based on vans or pick-up trucks. Others take the form of motorcycles, cars, buses, aircraft and boats.

The main problems facing city ambulance is road congestion. If the road is too crowded, the ambulance will be late ...

"CATCH" is a low cost, user-friendly, self-testing device which detects HIV. In emerging nations, this promotes individuals (who are prevented from travelling for miles to see a physician) to test for HIV at home.

Unfortunately, many individuals lack schooling due to a multitude of variables in emerging nations (including gender inequality, lack of infrastructure, poverty - the list goes on). CATCH is highly intuitive and anyone can use it. It is intended to do all the user's thinking and operates in three simple measures:
1. Sliding the disinfectant sleeve over the finger
2. Push down on the pipette/needle top
3. Press the button to see the result

This simple device has the potential to save millions of lives due ...

The invention addresses the problems of food and beverage preservation within minutes of time, which means in a situation where cooling beverages or food product is needed quickly, this product will be very useful. The basic idea of the invention is a very small or hand refrigerator that can instantly cool beverages or food products within a matter of minutes. This is done by using conduction heat exchange instead of convection for faster heat transfer between the coils and the cooling product.

Instant cooling hand refrigerator is a very small refrigerator intended for home and field use that can cool beverages and food products under a minute for preservation or satisfaction. This means there is a demand for fast ...

As long as kinetic energy recovery systems don’t supplant friction braking and discrete gear reduction levels haven’t been replaced with infinitely, or continuously variable transmissions, automobiles, trucks, and buses will continue to rely on reciprocating piston internal combustion engines and/or electric traction motors.

Technology exists for major step improvements in the thermal efficiency of fossil fuel engines. Advances made in micro-turbine power plants have made possible low-cost, high efficiency, and very high power-to-weight ratios. Companies such as Capstone Turbine Corporation, Williams International, and several others are producing these power sources electric power generation, light aviation, and rail and bus applications.

In 1976, Allison developed a gas-turbine 150kW power unit for the U.S. Army Patriot Missile System. The initial evaluation ...

I’m from Egypt at Africa. I have two inventions implemented to develop the night lighting system, patents No, 26771 year 2011 (Extra Spotlights through Xenon, Laser or LED Bulb) and patent No, 29238 year 2014 (A device that provides powerful lighting for all types of vehicles using lights tubes without dazzled) from the Academy of Scientific Research in Cairo Egypt.

Towards reduce the killing of 1.3 million human beings annually in road accidents (3500 daily) death cases occurs daily worldwide also every 6 seconds someone, somewhere in the world is suddenly and tragically killed because of injury, Their total amounts to 5 million deaths annually! (Even if the accident reduction rate is 10% the lives of 350 people will ...
