Our idea is to invent a device which can utilise the large amount of wind energy which is otherwise wasted. As today the fossil fuel is decreasing rampantly, and if another alternative will not be found in a few years then it will put great stress on the fossil fuels and as a result on the future generation.

Windmills that are used today has big structures, are hefty, and required large amount of area to install. Another problem is its installation cost is very high. It can ONLY be erected in open areas. Because of its height it is not suitable for aerial creatures like birds and also a danger for airplanes. The device which we have designed, check all ...

SOLAR-POWERED STRUCTURAL PRINTING USING IN SITU DESERT SAND

PURPOSE

Barren desert landscapes are difficult venues for construction due to low water supply, elevated temperatures, lack of a stable building foundation, and accessibility issues.

A low-cost, self-sustaining, solar-powered system is proposed, which automates large-scale 3D printing of roads and other structures, transforming sand, in situ, to a glassy, opaque and sterile solid as the construction material for roads, dwellings, drift walls etc..

There have been numerous NASA publications in which the regolith of the moon is sintered with microwave (RF) energy. Though the lunar regolith is well suited for this, it requires a significant amount of electrical power.

This approach employs focused solar energy for sintering, requiring much ...

The lateral axis wind turbine comprises of a pair of oppositely placed hubs in combination of plurality of extended radial arms symmetrically projected out wards and fitted on bearings to the central shaft. The turbine blades are pivoted between each extended pair of arms and are having the freedom to swing around their own axes and around the common axis of central shaft.

The central shaft comprises of a cam profile over which lever arms of turbine blades could engage during its working cycle. In operation, the streaming wind, forces the blade along the direction of wind while the extended lever arm turn towards the cam profile fitted around the central shaft. During power stroke the cam profile prevents ...

EnerSysNet [hereafter ESN] is in the sustainable energy business. Our lean, green machines turn forest waste into refinery feedstock. ESN will build, own or lease, and operate a network of mobile energy conversion [MEC] systems producing renewable liquid hydrocarbons [RLHs] directly from renewable woody biomass. The RLH produced can be sold to petroleum refineries where it is turned into gasoline, diesel or kerosene at the rate of 155 liters/barrel, displacing petroleum-based equivalents. Alternatively, the output can be used to fuel power generation equipment.

The MEC – a small, transportable self-contained processing plant based on unique, patent-pending technology – requires no external electricity; converts available feedstock in situ without any adverse environmental impact; yields high volumes of ‘green’ pollutant-free hydrocarbons, ...

Since the early 1950s electric utilities have installed millions of miles of low-voltage underground cables to improve the reliability and resilience of secondary power distribution. Early cable technology included butyl rubber insulated conductors and paper insulated lead coated cables. Over the decades, age and heat have degraded the insulation leading to catastrophic failures and underground fires that can pose a public and employee safety hazard, cause equipment damage, and result in prolonged power outages.

Assessing the condition of underground cables is expensive. Most test techniques are invasive (power outages are required), intrusive (cables need to be disconnected), and destructive (high voltages are applied to create partial discharges).

To address these issues, we propose a method that relates the health ...

There are about 60,000 MW of undeveloped hydro power in the US today (HR-267) and there are similar circumstances throughout the World. Any turbine under 10 meters of head or less than 10 m3/sec of water flow is so inefficient that they are not cost effective. Also, Western drought conditions have reduced historical hydro electrical production by 10%. It is time we looked at kW per gallon or volumetric efficiency as opposed to the mechanical efficiency which generally only measures friction loss.

The best way to capture this marginal unused hydraulic electrical potential is by using positive-displacement hydro-generation. A positive-displacement hydro-generator has the ability to produce some power at any head and flow. Low head sources can use the ...

Atrivu Synthetic Intelligence SmartGrid Solution (ASISGS) truly brings smarts via cognition to our nation's and the world power grids. ASISGS is a cloud-based service that truly provides the smarts for the nation's power grids. The seven domains of the current "smart grid" include bulk generation, transmission, distribution, markets, operations, service provider and customer. All may connect with ASISGS.

ASISGS address the functional activities needed across the grid including control, measurement, protection, recording, stabilization and optimization. Remember that the function of an electrical grid is not a single entity but an aggregate of multiple networks and multiple power generation companies with multiple operators employing varying levels of communication and coordination. ASISGS is a hyper-intelligent nucleus that binds all ...

The concept of ground-coupled heat exchanger system exemplified by the negligible surface area and least installation cost. This is well-known that at a sufficient depth the ground temperature is lower than the outside ambient temperature in summer and higher in winter. However, soil temperature on either side of the ground temperature depends on the type of soil and depth below the ground surface. Therefore, the ground water level is another important site factor in evaluating a potential ground thermal source.

Perched water commonly forms on hillsides in the regional low water table and spring to the regional water table. In such region, ground heat exchanger installed in sufficient depth and building wastewater drained to the system. Wastewater protects the ...

Energy is needed whenever and wherever we are regardless of the situation. And now there is.

When catastrophes strike and electricity is unavailable, we need the ability to charge our electronic devices and stay in touch with our loved ones. Regardless if we are out in the wilderness or are members of the military deployed overseas, charging our electronics while out in the vast lands is near impossible if we are unable to create our own power in any condition.

I have the solution.

My powerful Multi Powered Energy Generator is like no other. You can now charge the onboard battery in three ways.

Motion Power – A gentle movement will prompt ...

Multi-Purpose Desalination (MPD) is proposed to perform sea water desalination, while generates electricity and produces salt/minerals as a by-product using wave power.
MPD uses 100% ocean wave power, requires no electricity (Fig. 1).

Main facilities are located in the tidal area, that minimizes under water construction, and also operational and maintenance costs. Sea water is pumped to high land or tower by pump array powered by wave energy to create high hydraulic pressure required for desalination. Waste Sea water is used for electricity generation and salt/mineral production. The generator is located far above the sea level and hence is safer and easier for access. Sea animals are protected from entering the wave collector with nets under the sea level. ...
