This self-sustaining electricity generator needs to be located on a mountainside with a river flowing near it. The process begins with water evaporation using electricity to heat the water into its gaseous state. The steam engine is connected to an electric generator. From there, the steam rises through an insulated metal tube. Since the steam is lighter than the air, it will rise without any assistance to the top of the mountainside. On the top of the mountain, there will be 3 sterling engines on top of a water deposit. Here, it will produce electricity using the steam’s temperature. Using an atmospheric engine, it will convert the steam into water, which will then be collected in the same water ...

THE PROBLEM
If you're like me you can taste the difference between a beverage that has just been opened and one that has been opened for several days in the refrigerator. Orange juice in particular loses that appealing "just opened" taste after only a day or two. Since I don't always finish off a carton within a day or two after opening it I often experience a noticeable and undesirable change in taste. This happens with many types of beverages and since I usually purchase high quality beverages I dislike having to discard something because I can no longer enjoy its taste.

THE SOLUTION
My solution is the Stay Fresher Longer Dual-Chamber Beverage Carton. Looks and feels the same ...

Producing 1,000 m3 of fresh water per day requires approximately 10,000 tons of oil per year (equivalent to 35,000 tons annual carbon dioxide emissions). Apart from the obvious environmental concerns, this is something that few of the water-strapped areas of the world can afford. Besides, due to the energy crisis, search for sustainable energy alternatives is essential to supply the required energy of the desalination process. Over the years, solar energy has been used to purify water and numerous solar desalination devices are developed based on the principle of water vaporization, thus water vapor separation from dissolved matter, which is condensed afterwards as pure water.

Solar stills with the direct utilization of solar energy are the most suitable solar ...

ABSTRACT

Multi-Point Bacterial Abatement System is intended to be a component of the International Space Station's Water Recovery System. M-BAS implementation would result in the reduction of precipitate currently impacting ISS water recovery. Equipped with M-BAS, the WRS could recover more water – contributing to more sustainable ISS operation.

BACKGROUND

According to a January 2006, SAE Technical Paper “Status of the Regenerative ECLSS Water Recovery and Oxygen Generation Systems” and the follow up in May 2012, “Status of the Regenerative ECLS Water Recovery System” (2), urine pretreatment chemical sulfuric acid combined with calcium lost from astronaut’s bodies through micro-g induced hypercalciuria. The resulting compound precipitates as calcium sulfate solids. Therefore there is a correlation between the amount of bacterial ...

Product Idea: The said invention is a multi-powered battery operated electric tractor.

How it works: The electric tractor is driven by an electronically controlled traction motor, powered by on-board, high energy density traction batteries.

Why it is innovative: The said electric tractor is capable of accepting energy from multiple sources. a) on-board batteries b) Hybrid renewable energy sources - solar and wind. c) from an on-board mini internal combustion engine powered generator d) regular AC power outlet, through long cables wound on a drum, fixed to the vehicle. Handling multiple energy sources (requisite energy conversion AC--DC) is done through an electronic intelligent power handler device. The intelligent power handler manages the amount of energy flowing into and out of ...

Innovative Synergy of New Hybrid Off-Shore Wind Turbine/Permanent Magnet Motor/Generator Design with Renewable Energy Efficiencies

This project plan develops an innovative new wind turbine design which is already highly efficient and increases the efficiency of the wind power capture by synergistically linking the turbine power generation with another renewable technology. Coupled with MagLev Energy, Inc. (MEI) innovative permanent magnet motor technology, a hybrid solution generates continuous, zero emission, economical power with little or no fossil fuel dependence. Unique motor/generator design harvests back-EMF, demonstrates little or zero reluctance, and provides 60% input power reduction versus conventional electric motor technology. Commercial viability of off shore wind power capture will be significantly enhanced by innovative efficiencies from this project plan. Many other ...

Nutrients sink in the ocean. When they sink below the level of darkness, photosynthesis in plankton cannot proceed, and the nutrients are lost. The idea is to provide floating, wave-powered pumps that will pull the nutrient-laden deep water to the surface where it can fuel the biosphere. If the lit layer in the ocean is productive and alive, the atmosphere can be enriched and fish will be more plentiful.

There is but the smallest chance something like this could work, because economic support is so tenuous, if any can be found at all.

Here is a description of the floating pump:
1. A long tubular hose extends about 1000ft down (or more).
2. A floating platform keeps the top ...

Renewable energy production used by consumers (power, heat and cooling), together with hydrogen, is seen as the dominant future energy form. Using fuel cell technology, the two forms are effectively interchangeable (hydrogen and electricity), providing the potential for hydrogen to be a large-scale storage medium for electricity. Major technological and regulatory changes will be the basis of this new electricity service. The first path of technological change can be production of Combined Cooling, Heat and Power, at the consumers level, through demonstration technologies and projects. The project proposal aims to use renewable energy from the sun as efficiently as possible. The concept, in this project proposal, is to achieve energy supply for residential use, using fuel cell technology and ...

The major drawback to vegetable oils as automotive fuel has been the starting-from-cold problem. Briefly introducing some low flashpoint fuel such as hydrogen, gasoline or ether is a solution that has storage difficulties.

Water is safe to store, so producing hydrogen from water only on demand is attractive. My theory and design may allow electrolysis to happen fast enough to meet the expectations of a driver seated in a car and turning the ignition key.

My early experiments with direct current through softened tap water with no added electrolytes showed rapid degradation of current, from 7A to 3A in under four seconds. I conjecture this was due to "fogging" of the E field from buildup of hydroxyl ions at ...

The objective of the study was to redesign a photovoltaic ground mounting structure because the actual frame is not optimized. We used DEM software.

Italian legislation has stipulated that a photovoltaic ground mounting structure must resist four types of loads and their combination case: self-weight, wind, snow and non structural mass.

Combination case: (1,3 SW)+(1,3 NM)+(1,5 WL)+(0,75 SL)
SW: Self-weight
NM:non structural mass
WL:wind load
SL:snow load
Frame material: steel S235 (Fe360)

In the image we can see the result when I applied the same load case. The difference is than the weight of the structure at the left (BEFORE) is 42,18 Kg while the weight of the structure at the right (AFTER) is 22,15 Kg.
