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

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 ...
The UN Intergovernmental Panel on Climate Change (IPCC) have warned there is only a dozen years for global warming to be kept to a maximum of 1.5C. To restore carbon storage into oceans, plants and landmasses thus reducing greenhouse gasses (Carbon Dioxide and Methane) before the Earth becomes like Venus.

Using ferromagnetic repulsion from pyrolytic carbon and attraction to each other, a three column interactive oscillator produces harvested valence electrons for output power.
The inspirational journey to an autonomous renewable power source came from viewing a GE experiment (https://www.youtube.com/watch?v=C1CdUqNrj28) in 1936 which showed that by heating non-radiating non-retentive ferromagnetic material its property is temporarily changed to non-repulsive diamagnetic material, which is thermal transductance, do to the disruption of its molecular ...

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 ...

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 ...

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.
