A wave-powered electrical generator (WPEG) of novel design is proposed. WPEG operates by harnessing energy from the water waves, i.e., from an environmentally friendly source of energy. Briefly, WPEG consists of a geared motor-generator, accommodated by a double-cone, which is rolling on two eccentric circular rails. Eccentricity causes a divergent-convergent effect on the rails span (Fig. 1). During a motion toward divergent rails, potential energy of the double-cone is transformed into the kinetic energy of rotation and translation, i.e., into the energy associated to the “spin” of the double-cone around its axis of symmetry, and to the “revolution” of ...

ecoSPEARS is a technology conceptualized by NASA to bring a sustainable, long-term solution to PCB remediation in worldwide water supplies. Polychlorinated Biphenyls are the number one microscopic pollutants in the world’s water and yet very little is known to the general public about the detrimental health defects they cause or how widespread these pollutants are. Currently, the only methods of PCB remediation are dredging and capping, both of which are incredibly expensive, highly invasive, and do not actually remove PCBs from our water. ecoSPEARS provides a non-invasive, true solution to this issue by removing PCBs from the source of ...
Daylight optimizer is self-adjusting roof panelling technology to maximize (or optimize) the amount of day-lighting throughout the day inside a building.
The science of daylighting design is not just how to provide enough daylight to an occupied space, but how to do so without any undesirable side effects. Beyond adding windows or skylights to a space, it involves carefully balancing heat gain and loss, glare control, and variations in daylight availability. For example, successful daylighting designs will carefully consider the use of shading devices to reduce glare and excess contrast in the workspace. Additionally, window size and ...
The printed electronics market is currently estimated at around US $20 billion and it is expected to grow up to about US $73 billion by 2025. One of the major driving factor of the global printed electronics market is “substrate,” on which electronic or photonic devices are integrated. Presently, hard-to-recycle substrates, such as glass and plastics, are widely common. On the other hand, so-called “nanosheets” made of cellulose fibers with nanometer size diameter, are emerging substrate candidates. 100% nanocellulose films are still quite expensive and in this configuration, the substrate can only be used in liquid-free environments or devices. ...
In recent years the cost of wind and solar generation has dropped precipitously resulting in exponential growth. Governments are now setting goals of 50%, 80% or even 100% renewable generation, but for these goals to be met one critical element is missing: low cost electricity storage.
The preeminent technology is pumped storage hydro (“PSH”), with over 150 gigawatts installed and more planned. However, increasing construction costs and siting constraints are restricting expansion. Batteries are effective in some applications, but far too expensive at PSH scale. Neither of these technologies can solve the storage dilemma.
The Gravity Power Plant (GPP) provides ...

This innovation relates to the modification of the surface of solar panels to increase the efficiency. In essence, this technology will make use of flexible solar cells that can be made to conform to other than a planar surface. In this way, even if no optimal orientation at 90 degrees from the solar radiation angle, still higher efficiency can be obtained. This concept shares some similarities with a technique used in materials characterization called x-ray diffraction. In this technique, a powdered material is subjected to x-ray radiation and as the x-rays diffract they permit the identification of phases due ...

Today the world's population continues to grow, so does the amount of garbage that people produce. Today's fast lifestyle requires easily disposable products as soda cans or bottles of water etc. The accumulation of these products has led to increased plastic pollution around the world. Plastic is composed of major toxic products has the potential to cause a great harm to the environment in the form of air & land pollution. Some plastics are manufactured from recycled material but their use in engineering tends to be limited because the consistency of formulate & their physical properties tend to be less ...

The Closed Marine Energy Battery Technology or CMEBT is a technology which can provide the energy for humans for a period of more than a century from now. This technology produces no harmful end products. The main parameters which are to be followed are:
1. Selection of a coastal line or area
2. The area is to be far from human settlements
3. Biodiversity needs to be at a minimum preferably contaminated sites
The excavation of sand is to be done using good machinery. Before that, a guard wall needs to be constructed at least a hundred meter ...
Water wave energy and wind energy are types of sustainable energy resources.
To use these enormous energy resources this turbine design has been developed.
Design has following parts:
1. Wings (two or more in quantity to generate required magnitude of upward and downward lift)
3. Supporting rod
4. Bearing to rotate the whole turbine about the axis of support to accommodate the influence of fluid flow direction.
The wings are connected to the flywheel with the help of links/connecting rods that are hinged on central support to assist the wing’s upward and downward ...
The world will remain heavily dependent on fossil fuels such as oil, gas, and coal for the rest of this century for the purpose of power production. But if we don’t think about this then the day is not far where they all will be depleted. That’s is why the concept of extracting the free energy of the universe and to convert it to power to extend the lifetime of the system or to provide an endless power supply to the system has motivated many researchers towards this field.
In this developed system, we provide a new ...
