Sustainable Technologies

Wide application of the power stations based on use of renewable sources of energy, and the further working out of such technologies became very actual as a result of :
- Reduction of stocks of fossil energy carriers
- Growth of world power consumption
In the world The great number of various types of wind power stations, hydroelectric power stations using energy of current and waves, solar power stations, biofuel and other are developed.
For 2010 alternative energy sources provide no more than 2-15 % of required energy consumption.

Disadvantages of the existing power stations using renewable sources of energy:
* High cost of power stations and high cost of the electric power generated
* Necessity of building ...

Hydrobine Farm.

Hydroelectric power has been in service for over a century, but its origin, the water wheel, has been around for thousands of years. The ever increasing demand for renewable energies has encouraged engineers to find more ways to extract energy from the environment. One recent development is the Hydro Turbine aka. “hydrobine” which operated like a completely submerged water wheel in a stream.

A hydrobine can be installed anywhere there is moving water.

The hydrobine farms overcome many problem posed by other renewable systems. They are not visible from land, nor pose obstruction to people or sea animals. They are silent. The units are approximately 10 feet high and if installed in depths of 50 ...

The gradual increase in the rate of use of fossil fuels and natural gases are not only decreasing the underground balance, but also are polluting the nature, eventually depleting the environmental balance. What we need is a source by which we can decrease the pollution level and create an ecofriendly nature.

The idea of my design works on just simple laws of physics. A water tank will act as the water storage. From there, the water will pass to a vessel where electrolysis of the water shall be done with the help of a chargeable battery. The electrolysis process will split the water molecule into Hydrogen and Oxygen, which are the chief fuels in our device. Now ...

Synopsis:
Only about 30% of the fuel energy changes to useful work in Internal Combustion Engines (ICE`s). The exhaust exergy of the engine has approximately the same amount as the output work. So the exhaust flow shows great potential of useful work in which could be achieved by improving efficiency and applying new cycles to the engine. Turbo charger is of some mechanisms using the kinematic energy of the exhaust flow.

Using water in ICE`s is one of the most favorable concept to be worked on. Injecting water in the intake manifold, injecting water to the compressed exhaust products as a 6 stroke engine, etc. are of some to be named. But their biggest problems are low durability, high ...

Inflatable-Rotor Windmills

The inflatable-rotor windmill was initially conceived as a combination of the child’s toy pinwheel with an inflated lightweight sphere such as a beach ball. The sphere performs two main functions: as support for the pinwheel's blades or sails, and as a wind augmenter, to divert and accelerate air into the rotor. Both horizontal and vertical axis configuration can be made.

A wide variety of modifications can be envisioned, and the devices can also be scaled up quite a lot. The sphere shape can be modified to a torus, and in undeveloped regions, local materials such as bamboo and cloth used to produce a water-pumping windmill. The inflated spherical rotor can be mounted on a tall pole, and ...

The insulated pulse-combustion engine is a reciprocating piston engine concept which explores the five pathways of non-productive energy export from internal combustion engines (thermal conduction, exhaust heat, exhaust pressure, exhaust pollution, and mechanical losses) in an effort to improve fuel economy. This concept combines principle attributes of the Diesel engine (unthrottled induction and high compression ratio), of ceramic adiabatic engine prototypes of the early 1980s (thermal insulation), of current HCCI engine prototypes (isochoric heat addition), and of Ernest Chatterton’s “Simplic” 2-stroke engine prototype (isobaric heat rejection).

Several key philosophies of Chatterton’s Simplic engine, as documented in the 1975 book by L.J.K. Setright entitled, "Some Unusual Engines", are reprised in the IPC engine concept, including hyper-extended expansion cycle, induction preceding ...

A laboratory chemical stays most of its lifetime on a shelf, in a closed container, which is opened when it is necessary to take out part of its contents. Generally, partial removal is carried out by pouring, if the chemical is a liquid or a powder, or by means of a spatula after having tilted the container, if the chemical is a little-flowing solid. Both operations allow the exchange, by gravity or diffusion, of the atmosphere internal to the container with the laboratory atmosphere, containing the reactive species oxygen, water and carbon dioxide. One or more of these species first adsorb on the surface, then absorb, and then possibly react with the contents, degrading anyway the quality of the ...

This device would take advantage of the wasted air force generated from the outside air conditioner condensing unit.The proof of concept has already been proven with a prototype.The fan motor on my ac unit is 1/2 hp and blows enough wind to produce just over 8 volts from my unit.The goal is to charge small electronic devices and unplug the wall warts which are leeching power 24/7.When your ac turns on you are generating and charging your small devices or even led lighting.My neighbor has a larger ac unit and my unit generated over 20 volts.In conclusion the air blows reliably every 20 minutes or so. Let's take advantage of this wasted energy and put a dent in the ...

The Problem: Common residential exterior light fixtures that allow light pollution, light trespass and energy waste. Replacement of such fixtures (especially multiple exterior fixtures) can be prohibitively expensive.

The Solution: A light bulb with louvers designed into the sealed bulb envelope to keep light directed below the horizontal plane to meet modern full cut-off light fixture standards. When this louvered full cut-off bulb is placed in an older, exterior light fixture, light is directed towards the ground where it is needed rather than the sky where it is wasted.

19 U.S. states(1) have or are in the process of addressing light trespass and light pollution with requirements for full cut-off light fixtures on new or replacement structures. Many municipalities ...

This is a technology for generating hydro power by extending an enclosed pipeline in to the head waters from a hydro power turbine. This hydro power development is based on the fact that the flow through a closed conduit (pipe) will be greater than the free flow through an open channel. Water flowing though a closed conduit is a laminar flow while water flow in a river is a turbulent flow.

Furthermore a pipe line extension will help to generate stream line. Usually water in a reservoir starts from zero velocity and enters into pen stock and it has to develop a stream line before it reaches the turbine. If the length of the pen stock is short ...
