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.

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 ...

Our off-grid tiny home designs will be on a trailer powered by solar energy and propane. The goal is to use the latest in renewable technology to create a daily living space that is equal or better in providing comfort and the convenience of a larger home. The main difference between a Solarcycle tiny home design and other tiny homes is our focus on treating the home as a thermodynamic project involving long- term tiny home living issues such as waste management, ventilation, condensation, ergonomics, accessibility, energy efficiency, insulation, safety, and manufacturability. Right now, our prototype tiny home will include an incinerator toilet, solar power storage, propane heating and cooking, an energy recovery ventilator, LED lighting, and Aerogel insulation.

The purpose of the solar-silo is to decrease the geological footprint of solar arrays (using existing technologies) while maintaining maximum array output, eliminating solar tracking and reducing maintenance.

A solar-silo is a silo-shaped structure having a clear geodesic domed roof surrounding a solar array positioned around the inside perimeter with a clear cylindrical column containing a light refracting medium in the center of the structure.

Each geodesic segment of the clear geodesic domed roof has an attached Fresnel lens with its focal point passing through the top of the light refracting column (with only the top of the refracting column illuminated by the magnified light of the Fresnel lens). The refraction column consists of a closed clear cylindrical container, with a ...
