The Inverted Gas Turbine

Background

“Warming of the climate system is unequivocal.” [1] Fossil fuels have afforded humanity an unprecedented high standard of living at an equally high cost to the environment. As a run-of-the-river hydroelectric power station supervisor I have had the opportunity to experience firsthand the challenges of periodic unavailability of renewable energy. Wind solar and even water are not always available to meet energy demands. The inverted gas turbine cycle, was first implemented by Mordell in the 1950’s at the University of McGill; exhaust gases from a gas turbine were cooled and vented through a stack allowing the turbine to expand to pressures lower than ambient [2]. Mordell’s model economic failure (bulky design) stemmed research interest.

With this machine, the idea is to harness as much possible energy from as little space as possible.

With the horizontal blade configuration, the turbine doesn't lose energy in the process of resetting each blade to the top of the rotation circuit or in realigning to sudden changes in wind direction.

The mirrors reflect the sun light (If not just to the side which doesn't face the sun) at a higher concentration, allowing for more juice to be gained from each solar ...

Trash-a-nator is a device used to reduce the garbage produced. Here in India, disposal of garbage has always been a problem. People dump garbage on public grounds and segregation is not yet implemented. Apart from public waste they are dumped in land fills in an I'll mannered way because of which foul smell is produced affecting the settlements close by.

In the device you can put up to 50kg of domestic garbage like plastics, food packets, covers etc as long as it contains very less or no water content. Disposing food isn't preferred as waste food should be made into compost.

After putting your garbage, waste paper is used as fuel here which lit by a ...

Tri-comb(tm) Panel Core Structures were created to facilitate mass production of economical, high-performance panels. The real world applications are vast. Substantial savings in weight, materials, shipping and production costs are all simultaneously possible when Tri-comb(tm) replaces conventional panels or even honeycomb. Tri-comb(tm) opens up new possibilities for better LEED compliant building materials.

We wanted a moldable high-performance panel at a bargain price. Honeycomb panels are one of the most efficient panel designs ever devised, but they are difficult and expensive to manufacture. Because of these and other design application issues, honeycomb is rarely ever used in consumer grade products. It is primarily used in expensive high-tech applications where the cost and manufacturing difficulties are justified by performance requirements and ...

Air source heat pumps are generally known, but their fans produce acoustic noise. The fence heat exchanger does not need fans due to large surface area. When a liquid refrigerant at a low temperature and low pressure passes through the tube fence heat exchanger, ambient heat causes the liquid to boil and the liquid is changing to gas. The gas passes up in the fence tubes and is preheated. The absorbed heat is stored in the gaseous refrigerant and a compressor increases the temperature of the gas. Inside the house, the hot gas passes through heat exchanger. There, the hot refrigerant gas transfers the stored heat to the indoor water heating and hot water system. Then the gas passes ...

Blades of the turbine have cuts which open cavities inside the blades. The stream of air or water comes inside the blade and presses inside too.

Thus the area of pressure of a wind or water increases almost in 2 times without change of a configuration of the blade.

Pressure inside the blade will not be compensated by pressure from above. On the contrary - they will be summarized.

Accordingly capacity of the turbine increases in 2 times too.

Rigidity of the blade does not decrease thus. Longerons and ribs provide stability of the blade and reduce its weight.

More complex jet variants of such turbine are possible. In this case the turbine will have the second cut on ...

No problem has ever rounded global leaders together quite like the global energy crisis. Oil geologists and analysts have forecast the impending global Peak Oil, a point at which the maximum rate of petroleum extraction is reached, followed by irreversible decline. To date, 50 countries have already surpassed the point of no return. A 2010 Oxford study states that by 2015, global oil demand will surpass its supply, where 61.7% of that demand comes from the transportation sector. Action can still be taken however, and one of the most commercially viable ways to do so is by transforming the world’s consumption of transport fuels.

With this goal in mind, a group of UBC students has designed ...

We have developed a novel wind turbine that overcomes the solidity limitation of conventional designs, by opening the center of the rotor which allows to increase the number of blades without incurring loss of efficiency. According to our design, it is possible to increase solidity up to 0.25 (the recommended limit for three-bladed rotor is 0.1). Another important characteristic of our design is that the blades have a wing profile and twist, which is a function of the angle beta (between plane of rotation and chord at blade tip). The blades have a length equal to one/third of radius, which means that the inner opening amounts to one half of the complete circle. The set of blades are mounted ...

UltraSpin
J & M Associates is a Philadelphia firm creating environmental technologies that economically produce solutions to water, waste water, oil produced water,gas fracking water and valuable fluid recycling problems. We have developed a non-disposable, non-clogging, advanced ceramic filter which is able to recycle water and industrial fluids that are now considered waste. After using our filtration system, the recovered materials can be reused. “Ultra-spin” technology (patented) has strong sustainable profit potential and can return many times the initial investment. We received patent approval and are currently looking for funding to build a prototype, so that we can enter this $12 billion water market and make today’s competitors tomorrow’s customers.

J & M Associates has developed a proprietary ceramic ...

In order for the various participants in our working society to properly understand where they fit in and to appreciate how they can operate in the most effective manner, it is necessary for their education that the can understand HOW OUR SOCIAL SYSTEM WORKS.

The fact is that we have a system which has been very poorly understood in the past, and the various macroeconomics theories and simulations of it have failed to achieve the desired results in terms of overall success by all parties (or as many of them as possible). Indeed, we do have such a system!

This proposal relates to good government and to the successful participation in the production process or ...
