Biological resources are abundant in developing countries in the tropic regions. Such resources found are biomass and oil seeds, however, these resources are not being used to their maximum efficiency due to the fact they do not have the industrial means to utilize them. Although seed oil is easily acquired in the tropics and is the main ingredient in biodiesel, additional raw materials like ethanol or methanol and a base catalyst like sodium hydroxide or potassium hydroxide are needed in the production of biodiesel. Industry-grade compounds are typically not available to the rural areas in Africa. From this comes our motivation for this project to use only local resources to extract methanol, make lye, and use seed oil to produce biodiesel, and to also take advantage of the byproducts by either recycling them back in to the process or producing useful substances i.g. soap.  So, methods for extracting methanol and obtaining oil are available, but a base catalyst (potassium hydroxide or

The interest in the development of solar electricity, has led to the advancement of new avenues that address the issues of cost and efficiency associated with photovoltaics (PV). To this end, one of the prominent approaches being explored is thin film solar cell (TFSC) technology, which offers prospects of lower material costs and enables larger units of manufacture than conventional wafer based technology. However, TFSC technologies suffer from one major problem; they have lower efficiencies than conventional wafer based solar cell devices. This lesser efficiency is based on a number of reasons, one of which is that with less material, there is less volume for the absorption of incident light. This shortcoming leads to the need for optical light trapping; which is concerned with admitting the maximum amount of light into the solar cell and keeping the light within the structure for as long as possible.

 

The goal if this project is to present a host of improved light trapping methodolo

The concept proposed here is based on the possibility of converting the heat produced by the stoves and furnaces into light by transmitting it through optical fibres to all the areas that need to be illuminated.

Introduction:

Fuel cells are clean source of energy. They can be used as a source of heat and electricity. They can operate buildings’ power and vehicles’ motors. Fuel cells operate best on pure hydrogen. The hydrogen fuel cell operates similar to a battery. It has two electrodes, an anode and a cathode, separated by a membrane. Oxygen passes over one electrode and hydrogen over the other. The hydrogen reacts to a catalyst on the electrode anode that converts the hydrogen gas into negatively charged electrons (e-) and positively charged ions (H+). The electrons flow out of the cell to be used as electrical energy. The hydrogen ions move through the electrolyte membrane to the cathode electrode where they combine with oxygen and the electrons to produce water. Unlike batteries, fuel cells never run out.

 

Research Problem

There are two main problems with the current technology of developing fuel cells. Firstly, the high cost of the energy. Secondly, the huge storage area of the hydroge

"FlameStower creates off-grid, energy efficient solutions now, designed for durability and ease of use for those who need it most” 

www.flamestower.com

 

FlameStower rethinks energy. Our product - a small, portable generator that captures waste heat from campfires, cook stoves, any open flame and converts it directly into useable electricity - is designed for off-grid locations where mobile phone use far outreaches grid availability. People need an affordable, any time solution to bridge the “IT Divide," and we believe FlameStower is the solution.

FlameStower keeps all of us online when we're off-grid: outdoor adventurers who want a light-weight, easy to use, durable power supply; professionals requiring reliability over all else, no fragile parts, an ideal solution where IT lasts mere hours; communities in the developing world where there are no power lines. Its not a lot of energy, but the low power demands of modern devices fundamentally change global energy strategies: one of t

Solar Power, two words that describe an amazing way to generate clean electricity but have yet to be fully employed. The reason solar power has not been the champion of clean energy thus far is simple, economics. Basically, the total energy generated from commercially available solar panels over their lifetime saves the consumer enough money to barely break even with the total cost of the solar panel plus installation. As you can already see, the simple reason has become more complex. Economic incentive has revealed that it is actually a matter of efficiency, both of the solar panel itself and of the process used to create it. 

The first issue is that today's solar panels take a lot of energy to make and are therefore inherently expensive. The reason they are expensive is that they consist mostly of silicone, which is formed in a process at very high temperature. To achieve a viable method to mass produce solar panels, a large amount of capital is required just to build the specialize

A Scheffler reflector is a parabolic dish that repurposes sunlight for cooking in developing nations.  Improving this model, we have lowered the cost and maintained efficiency .  We are also implementing a high-efficiency photovoltaic module to create energy, which would be ~ $0.10 per thermal watt.  This process would create a byproduct of hot water where applicable.  This technology would be appropriate in developed nations, particularly on large industrial rooftops where there is adequate space.

When cars are driven, mechanical vibrations are produced. Just like excess heat, mechanical vibrations are considered waste energy.

The idea is to convert the mechanical vibrations into electric energy to recharge the battery of an electric car.

This can be done by utilizing piezoelectricity.

Piezoelectricity is considered the key to harness waste vibrations. It is the electric charge produced in chrystalline materials such as ceramics with crystal structures.

Piezoelectric materials such as nanotubes and nanowires can be used in cars where they are packaged into a device so that the vibrations would cause strain that could be extracted by connecting an electric circuit that delivers electric power to the battery.

This idea is to harvest energy from waves using a modified point absorber that includes two movable arms mounted at 180 degrees to one another. This set up allows the WEC to collect energy from the same wave three times. As the waves hit the first arm of the WEC, the kinetic energy in the wave pushes a buoy attached to the arm upward which would then push a hydraulic piston. That piston would push fluid through a system of hydraulic hoses and collect in an accumulator. The wave would then approach a point absorbing buoy that rides on a spar. As the wave pushes the buoy upward, the buoyant force exerted on the buoy by the water is transferred to a large hydraulic piston. The piston would then push fluid through the hydraulic system to the accumulator. The wave then approaches the second arm and would push the arm upward using the kinetic energy of the wave and act on a hydraulic piston pushing fluid to an accumulator. The use of an accumulator is to allow for a constant and controlled f

My idea is to use a tree as a windmill.  I purpose to use the motion of the tree swaying in the wind to raise a Weighted Pump.  The Weighted Pump would push air (or water but a holding tank would be needed) into a regular Centrifugal Pump.  The Centrifugal Pump would drive a Generator suppling power. The lines coming from the tree top (about 2/3 the way up the tree really) should be encased in a tube to protect the system and local wild life. The reason a Weighted Pump would be used (instead of a spring, gears or other pump) is so that a smoother power would be supplied from the generator.  Lines could be run down large branches as well. A system like this would easily allow for other nearby trees to supply the same Centrifugal Pump.
