Sustainable Technologies - 2017
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 ...
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 ...

This preliminary design is based in our aim to irrigate the Peruvian coastal desert, via desalting sea/brackish/RH water captured in brines and/or preserving seasonal water were evapotranspiration is very high. All these are salty solutions that need to be convertedt to usable water. All this can be done by current RO or distillation but both are energy intensive.
Our experimental work has confirmed previous scientific work, that low density water (LDW) exists and is polymeric, lighter and, believe or not, kind of hydrophobic. In simple terms it is “icelike.” For simplicity's sake, we consider that in water schemes, the ...
Water is something that we here in Canada take for granted, yet nearly 1 billion people across the globe don’t have access to safe and clean drinking water due to cost, contamination and climate change. Our design project looks to alleviate this burden through the use of an atmospheric water generator (A.W.G). Our project objective was to develop a working prototype with the capacity to produce the average adult daily drinking water requirement of 3L.
Today, A.W.G. is predominantly performed by the circulation and compression of refrigerants through cooling coils which air is passed over similar to the operation ...
In both the chemical and mechanical pulping process, the logs are cut into wood chips by a cone shape tool before fiber separation. To make the wood chopping process more efficient, one has to investigate in detail the coupling between process parameters and the quality of the chips. One objective of thesis was to obtain an understanding of the fundamental mechanisms behind the creation of wood chips. Another objective with the thesis was to investigate whether it was possible to, in a way, tailor the chopping process so as to reduce the energy consumption in a following mechanical refining ...
Three important factors guarantee the performance of a generation chain of renewable energy are their efficiency, production cost and simplicity of the control algorithm to achieve a practical implementation in real time. Thus, three-generation chain structures of renewable energy are presented and studied in this paper for a selective comparative study to knowledge:
• Renewable Energy structure with DC-DC inverter elevator as protection system.
• Renewable Energy structure with excitation current regulator as protection system.
• Renewable Energy structure with regulated braking torque as protection system.
These three types of energy generation chain are modeled simulation environment Matlab-Simulink. ...
This project for community services represents the designing and development of an alternate excavator arm which can be used without the electric supply or by consumption of fuel at a consistent turn. The project primarily aims at bringing the engineering technologies and innovative designs at the easiest disposal of the community to reduce efforts of the people to simple day to day activities and also to reduce time to do a specific task with the least efforts. Therefore, efforts have been taken to keep in focus the conventional objectives of the project, and a sustainable model with the no ...
This innovation entitled “Development of Bio-Composites Using Banana Stems and Used Paper Waste for Sound Control Application in Building" deals with the development and successful use of eco friendly process in the production of banana stems and used paper waste based bio-composite materials for sound control applications in civil construction. Both materials which are normally wasted, and have great potential for being developed as bio-composites for industrial applications.
Once the proposed value chain on utilization of banana stems and used papers are established as main raw materials, substantial benefits are expected to accrue for farmers, textile and paper industries. ...

A new technology that can combust, gasify or pyrolyze solids, liquids and sludges and divide the process into multiple stages and manage each stage of conversion for optimum results and “engineer” the fuel liquids and gases produced in continuously recharged conversion chambers where selected conversion processes can be automatically computer optimized for each of the feedstocks being individually processed and that can be made and marketed worldwide.
1. GENERAL DESCRIPTION
The Sequential Grates (tm) conversion system consists of a tall, free standing and self-contained, firebrick or ceramic lined dryer, combustor, furnace, gasifier, pyrolysis unit ...
