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 ...

Noise Pollution is the biggest problem faced by all the countries and all of them are investing a huge amount of money as well as time to solve the problem of pollution. Noise to electricity is not only solves one of the greatest problem of noise pollution but also gives the most demand able output which is electricity.

A loudspeaker (or speaker) is a transducer, which converts an electrical signal into sound waves. Since noise is also a form of sound wave or mixture of different kinds of waves, which gets wasted in the environment, so by law of conservation of energy it can be converted into another form of energy i.e. electrical energy, so by using a speaker ...

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 ...

In extreme hot summer, many people, particularly the elderly, can suffer heat-stroke and die. For example, in 2018, there were more than 65,000 global deaths due to extreme heat wave. Therefore, air-conditioning is no longer a luxury but a necessity.
Air conditioners literally save lives and improve quality of life both at home and at work. So why are air conditioners not available everywhere? Present day air conditioners, invented in 1902, face a number of challenges. Firstly, they consume huge amounts of energy; secondly, they cause significant environmental detriment due to the use of chemical refrigerants; and lastly, to cool a desired location, they dissipate large amounts of heat to the environment; creating undesirable heat zones.

Conventional water-based ...

A solar power satellite (SPS) constellation is an impressive way to transform the Sun's radiant energy into electric power when efficiently streamed down to Earth. The generic SPS has long been promoted as a potent solution for the ever increasing global energy demands. It certainly is a non-polluting and independent method of harvesting energy from the Sun's intenst radiation, as against many other terrestrial sources of energy. Conventional concepts of the SPS have all considered a single large satellite to be located in geosynchronous or geostationary orbit (GEO), at distances of 36,000 km. Given the significant power attenuation and loss during transmission that is expected across those distances, such an arrangement is fit to be replaced with a greater ...

Gripped interlocking solar panel mechanism is designed to incorporate transparent silicone glass additive/filament manufacturing. The transparent silicone glass filament adhesive covers the solar panels top surface area enabling a gripped textured solar panel. The transparent silicone glass adhesive filament acts as a water/weather proofing containment lining as well as a tempreture residual resistant thermally conductive materialed coating. Silicone rubberized glass adhesive filaments acts as an insulating Barrier/layer for the solar panel. The silicone glass adhesive filament doesn't shrink or warp causing no structural stress. Acts as a protective gripped layering/lining. The gripped solar panel is applied for drawbridges, bridges, roads, personal driveways, parking lots sidewalks etc. 3D printing using transparent silicone rubberized glass filaments/additives would be very cost effective ...

The Maz21 energy concept evolved from the water web concept of 2018 (https://www.entrepreneurship-campus.org/ideas/16/10791/). It seeks to generate power in a cost effective way. It utilizes kinetic water turbines fixed in a series inside a 80cm internal diameter polyethylene tube. The whole system will have 4 kinetic water turbines which shall be connected to form a complete cycle. The water shall flow inside the tubes by a force from the Magnito-hydro dynamics propulsion units, designed and inserted in the tubes.
The water used in the maz21 energy concept shall be ionized in order to improve current density and reduce the joules effect resulting poor conductivity.
The whole system has a unique infrastructure design, this means the system shall burried in ...

We have developed an integrated air quality monitoring UAS which also has collision avoidance technique to avoid collision with real time obstacles while monitoring. We have used an ultrasonic sensor for collision avoidance and mq135 for air quality sensing. We have developed a program for displaying the pollution gas availablity in percentage instead of ppm.

An anti collision system is essential for safe flight of the drone. It gives a simple solution for obstacle detection and collision avoidance in UAVs. The obstacle is detected using the ultrasonic sensor (HC-SR04).

Ultrasonic sensors work by emitting sound waves at a frequency too high for humans to hear. They then wait for the sound to be reflected back, calculating distance based on ...

NASA Langley Research Center has developed a novel fine interpolation technique that is useful in signal processing for applications in lidar, sonar, radar and similar modalities. The interpolation technique uses repeating waveforms, Fourier transform reordering, and Richardson-Lucy deconvolution to obtain faster and more accurate results.The prime target application is range finding, but the technique is equally suitable for differential absorption studies, such as determining CO2 concentrations in the atmosphere.

Benefits

Provides an interpolation scheme much faster than those currently in use
Consists of a simple reordering of a Fourier transform array
Can be applied broadly with any repeating waveform, and not confined to PN code and PSK modulation
Compatible with lidar, radar, sonar and similar modalities

NASA Langley Research Center has developed a compact self-tuning damper to reduce vibration occurring at a fixed frequency. Tuned dampers reduce vibration of the base structure by the dissipation of energy. The magnitude of the dissipated energy is proportional to the range of motion. The NASA damper design allows the slider mass to achieve 2x-3x greater range of motion than that found in conventional devices. This enables 4x-9x more effectiveness for the same size and weight; or the same effectiveness for a 4x-9x decrease in weight. The damper is self-tunable and can be adjusted in effectiveness. The damper can be made small enough for use in wind tunnel tests or scaled up to large sizes, like those used in ...
