When blind persons (BP in further text), approach street crossroads with trafffic lights, they usually face the issue, how to detect WHICH beep sound is for WHICH direction? Beep sound is the same for both directions, although there are some tries to make 2 different beeps, they are not connected to walk direction at all.

In some cities in the US, beeps are connected with north-south and east-wast directions of streets, but that is very specific situation and cannot be applied to the rest of the world.

Eg., if you want to go “left” or “forward,” and you hear the beep sound, you do not know which direction is safe to go.

BUT, if we could have some object ...

The plan is to develop a refined HPWH optimized for a home with a PV system in three major ways not found on typical HPWHs. It is significantly more efficient than current HPWHs since it can extract heat from water as well as air, it can store low-cost energy to reduce use of higher cost energy, and it can talk to the web and the grid to “know” when to store and when to use energy for the best savings from the PV system. This is an improvement over current HPWHs because it eliminates most of the fan noise and cold air they produce. With higher efficiency, better use of available energy, and less noise, this design will advance ...

The TumbleDown Self-Turning Vertical Composting System repeatedly and thoroughly mixes ("turns") compost without machinery or labor. The design resembles a multiple helix spiral staircase within a silo. The mixture of organic materials tumbles down from one stairstep to the next. “Self-Turning” refers only to the spontaneous tumbling of the compost. The structure itself does not move and has no moving parts.

The process is driven by two of nature's most powerful forces, gravity and decomposition.

Compostable waste is loaded at the top of the silo. Each stairstepful of organic matter is propped up by the compost on the stairstep just below and in turn props up the mass of compost on the stairstep just above. As decomposition progresses, the tangle ...

This turbine differs that has two additional elements - a turbo-expander in the center and jet cuts on blades. The turbo expander absorbs wind energy. Thus the non-working center of the turbine becomes effective. In some versions, the fairing itself will have grooves absorbing wind energy.

Blades of the turbine have cuts which open cavities inside the blades. The stream of air comes inside the blade and presses inside too. Thus the area of pressure of a wind increases almost in 2 times without change of a configuration of the blade. The wind presses on the bottom and top surface simultaneously from within. Accordingly the capacity of the turbine increases maximum in 2 times too, minimum on 50 % depending ...

Experts have estimated that 8.3 billion metric tons of plastics have been made and approximately 5 billion metric tons have already been discarded, with an abysmal recycling rate of only 600 million metric tons. This is despite the fact that recycling alone can save 40 to 90 percent of the inherent energy in plastics relative to the production of virgin plastics—energy savings, which if harnessed, could result in massive-scale economic and environmental advantages. Up to 40 percent of all plastics are used for minutes to hours to days in single-use packaging applications (items commonly composed of plastics like polyethylene, polypropylene, polystyrene, or polyethylene terephthalate, also known as PET), while the estimated time for many plastics to degrade in a ...

Air-conditioning systems spend most (up to 90%) effort on cooling air. Cooling people is just a byproduct of the whole process. To reduce energy demand we need to implement approaches that reverse this situation and focus on directly cooling people with minimum conditioning of surrounding air.

Based on the ASHRAE Standards, thermal comfort is defined based on an average between air temperature and Median Radiant Temperature (MRT) of surrounding surfaces. Hence, lowering the MRT enables us to achieve thermal comfort without intensive use of air-conditioning.

Standard radiant cooling enables lower MRT through cold panels attached or embedded to ceilings, floors and/or walls. Cool water is continuously pumped through a network of pipes bonded to the panels to keep them ...

There is a huge energy expenses for a motor pump or submersible pump to lift water from an underground reserve tank to rooftop water tank. Not only is it expensive but air pollution is created (indirectly for power generation). Except it, the supplied water from govt. or agency is not suitable for direct use/drinking. There is a need to purify the water for drinking and for it some energy/power is expensed. This invention will solve these problems and will give release from maintenance of motor pump and will save the world from warming.

For this system, a metal water tank (Fig -B) to be installed at some down position of the underground reserve water tank. A metal jacket to ...

Over two billion people suffer from the effects of water scarcity and the vast majority of those affected live in coastal areas in developing countries and remote communities. Seawater desalination is an excellent potential solution, but desalination systems require a connection to a strong and reliable electrical grid for their power supply.

Because our target customers typically lack sufficient grid capacity and cannot afford the capital or time required to build and deploy grid-connected systems, Resolute Marine has devised a unique solution to this problem - the world’s first wave-driven desalination system (Wave2O™) that can be deployed quickly, operate completely “off-grid” and supply large quantities of clean fresh water at competitive cost.

Our solution has the unique advantage of ...

Z-PEC Zero–Point Energy Converter 

According to Quantum Electrodynamics, otherwise empty space is filled with tremendous energy; it’s called the Quantum Flux or Zero-Point Energy. Z-PEC will mechanically tap this unlimited resource for pollution-less electrical generation and pollution-less vehicular-propulsion.

• A Z-PEC prototype can be built by sputtering layers of metals and refractive-materials onto a silicon chip.

Peer-reviewed experiments support the underlying tenets of this paper.

• Obeys the Laws of Motion, Thermodynamics and Momentum Conservation.
• Fig. 1 illustrates how to get a net force from the isotropic momentum of the Electromagnetic Field of the Quantum Flux.

Refer to Fig. 1; it illustrates the paths of an average pair of equal and opposite photons of the Quantum Flux. ...
