Fullspeed Technology Inc. is a Canadian company led by Greg Ahira, an entrepreneur whose vision is to create and bring to market innovative productions. Fullspeed is developing a unique test strip product, “RightMix Strips,” that displays the mixture ratio of oil and fuel used in a two-stroke engine. An ethanol test strip product is also being developed to detect the level of ethanol in fuel. These products are anticipated to be in the market by end of 2013 and are based on nanotechnology.

According to the U.S. Environmental Protection Agency (EPA), nationally, mobile sources which include lawn and garden equipment represent the largest contributor to air toxics. Mobile sources pollute the air through combustion and fuel evaporation. These emissions ...

Most of the companies in Mombasa have been recycling plastic waste, glasses,and metallic waste leaving the heap of organic waste which forms 75% of the total garbage.

Open-air markets, beach hotels, fast food restaurants, and homes produce more than 200 tons of organic waste per day. The majority being fruits and vegetables.

In accordance with the research and a simple lab analysis conducted by low-level youth bunge group, we discovered that when we crushed sample of different fruits and vegetables waste, mixed them with water, and left them to ferment in tightly sealed container, 200 grammes of this waste produced 554.25cm3 of methane gas in an inverted cylinder.

After this experiment through considering several ...

Imagine a renewable energy source that can produce energy at a cost comparable to natural gas or hydroelectric generators using fewer resources, while being environmentally friendly.  Lux Wind Turbines are expected to cost less than 1/2 of conventional turbines and can be spaced closer together to extract more power with less land.

The Problem:

Conventional three bladed wind turbines are expensive because they are overweight.  They require excessive material to support the cantilevered tower and each of the three cantilevered blades.  (These cantilevered beams are supported only at one end and, from a design perspective, are only used when nothing else will work.)

The Solution:

The Lux Wind Turbine, a vertical axis wind turbine (VAWT) ...

The poor performance of today's thermic engines is due to the temperature inhomogeneity of the hot air. With today fuel injection, it’s difficult to obtain a uniform and stoichiometric air/fuel mixture in the combustion chamber, in the extremely short deadlines (the order of ms), while the volume ratio air/vaporized fuel volume is in the order of 100. In these motors, the temperature profile is a paraboloid of revolution ( Fig 1); the air temperature is at its maximum, near the point of injection; then because of jet dispersion, it decreases stepwise from 1300 ° C to 170 ° C. But ideally, the temperature should be uniform at 1000 ° C. Calculating (cold source at 85 ° C) the thermodynamic ...

Solar energy is a dilute form of energy, to achieve temperatures above 90°C, the concentration of Solar radiations is must. Various types of concentrators are developed, namely Concave reflective, Convex transmissive, Fresnel lens based, Cylindrical line focusing or Spherical/Parabolic point focusing and so on. All these concentrators, depending upon the concentration ratio and overall system efficiency, achieve the higher temperatures up to 1000 °C. To aim the focal point of concentration on collector device as per the Sun’s movement (Hourly, Daily and equinox based), the tracking of concentrator either uni-axial or bi-axial is required. This tracking mechanism involves servo motors with gearbox, control system and robust mechanical structures which will enable precision tracking and withstand the atmospheric conditions.

If I can to tune a broadcasting station, then I also can tune the sun's light because the light is an electromagnetic wave.

The tuning circuit (coil+capacitor) captures the electromagnetic signal from the light and generate
voltage.

In my country the resources do not exist for this project. Only the United States can do this project, because it uses ...

Untethered Autonomous Flying Wind Power Plant

Conventional wind power plants (WPP) have their limits due to the low energy density and fluctuations of surface winds, as well as their low efficiency. The idea of harnessing the more intensive, persistent high-altitude winds seems to be promising. Known devices are floating in the air and tethered to the ground. The energy generated should be transmitted to the ground through a cable, arranged parallel to the tether.

The question whether the tether has any functions that make it indispensible arises.

Our answer is NO.

Untethered flying units (gliders, Fig 1.)are also capable of harvesting wind energy, using updrafts and windgradients.

Temporary energy storage on the plane is the most critical problem of ...

Surprisingly, if you bring a pendulum to the side, it will start to oscillate in a plan that remains unchanged even though you rotate its base. This is how Foucault demonstrated the rotation of the Earth.

This counterintuitive behavior could be used as a free source of energy. The energy spent by the Earth to force the plane of the pendulum to be changed can generate electricity via a generator or other means.

Technically speaking, we must bring up a good degree of vacuum inside the enclosure to avoid air friction against the mass of the pendulum. Also, the friction at the rotation axis must be reduced to a minimum to harness a substantial amount of energy. The ...

Trap grease is a mixture of water, solids, fat, oil and grease (FOG) that accumulate in grease traps/interceptors and sewer pipes. The FOG content in the trap grease is the major cause of the clogging and corrosion of municipal sewer pipes. The annual generation of trap grease is significant and the maintenance costs are huge for flushing the blockage and fixing the leakage of pipelines caused by trap grease accumulation. The current trap grease management practices are costly and ineffective, which leaves burdens on environmental, social and economical welfare for the society. Trap grease converges in the wastewater treatment plant (WWTP) and the buoyant trap grease-containing layer is scooped off, transferred to drying tank and finally sent to landfill. ...

Some of the greatest technological advances in modern day society have involved the improvements of the fuel efficiency in vehicles. However, a challenge arises with a current problem. In electrical systems, electricity is produced directly from the engine through the alternator, using up valuable fuel that could otherwise be used to keep the vehicle in motion. A simple and feasible solution is offered below that may change the idea of vehicle innovations here forth, along with attitudes towards renewable energy.

The proposed solution is the attachment of a wind turbine powered charger to the vehicle that is driven by the motion of the vehicle when traveling. This charger would then power all electronic systems in the vehicle, not directly ...
