1-What is the unmet need we are trying to address?

-Kessler syndrome causes the exponential growth in numbers of formation of space debris. The Kessler syndrome causes trouble because of (1)domino effect,(2)feedback runaway exploration that occurs in higher orbits.
-These result in hostile action and collision of this debris with defunct satellites or space stations which results in catastrophic destruction.
-The speed of the space debris particles is like 10 times faster than a bullet so no one cannot get that. Also, the size of the debris is smaller than 1mm, so it may damage optics and solar arrays. So while a spacecraft may survive being hit by tiny debris, such hits can still result in catastrophe and mission ...

At this point, awareness of plastic is not an issue. The critical point is proposing new ways to replace, manage and dispose of plastic material that is used for a different use. One of the widely used plastics is plastic bottle packaging. This packaging helps plastic bottles be easily manageable for storage and transportation. But as you surely noticed those plastic packaging end up in landfills as they are easy to manufacture.

This project offers a new type of packaging plastic bottles so that plastic packaging will be omitted. This mechanism is very simple less cost and do the task. The device is using hard plastic belt type mechanism to hold the plastic bottles together. Since the bottom part ...

According to Chemistry About.com, chewing gum was originally made from tree sap called chicle, a natural rubber, and sometimes various waxes. But After World War II, chemists learned to make synthetic rubber, which came to replace most natural rubber in chewing gum (e.g., polyethylene and polyvinyl acetate). polyvinyl acetate (a type of plastic) is manufactured using vinyl acetate, a chemical shown to cause tumors in lab rats. In fact, in 2008 the Canadian government was so concerned about vinyl acetate used in the production of chewing gum that they added it to a list of substances to be considered toxic. However, according to the article, government regulators were forced to back down due to industry pressure. Where does (plastic) ...

Acoustic Transducer Diaphragm - Boxless, Omnidirectional, Full-Range

US patent 7,860,265 Planot® acoustic transducer diaphragm. The most common electromechanical device in the world is the speaker. I have reinvented and vastly improved it. The first Planotary design under development; compact and VastFidelity™.

The Planot diaphragm pivots along its long axis; unlike previous Planots its bearings, as well as the magnet-homing-damping device, are housed “inside” of the diaphragm. The external support “mast” for the diaphragm is eliminated by the single, internal and stationary axle. The sound is improved, the cost is lowered and the size is reduced. This diaphragm has a surface area of 32 sq. in. A typical 6 inch speaker has an area of 21.21 sq. in.

“Omnidirectional is ...

eShepherd is a world-first livestock virtual herding solution that provides remote pasture management, and animal monitoring for improved livestock and land welfare. Developed in Australia for the global market, eShepherd helps farmers manage their animals and land more effectively in the face of climate change.

eShepherd is an IoT driven platform comprising a GPS enabled neckband and cloud-based application which is used to fence, move and monitor livestock by detecting and responding to animal behaviour. Farmers use a cloud-based web application to create virtual paddock boundaries and check on livestock activity, all of which are updated dynamically to ensure accurate data. eShepherd contains a patented training program, refined through years of evidence-based research and development. The system responds to animal ...

The team ENENT believes that the efficiency of the existing systems could drastically be improved by inculcating innovative techniques into it. Following our vision, the team made an innovation power distribution device that saves 20%-25% of the electricity bills. The device shifts phases in milliseconds to prevent imbalance being created into the system. This reduce the excess energy losses during the distribution of power. The cost of the device is just $300 and the device can easily be plugged into a conventional power distribution system with minor modification. The price could on average be recovered in about 6-7 months of installation through electricity bill savings.

Apart from balancing loads and reducing electricity bills, the device also ensures that your ...

Because most kinds of oil are less dense than water, most oil floats on the water surface. It spreads out and is pushed across the water by wind and currents. Most kind of oil can block sunlight below the ocean. This results in no life under and around the area in which any kind of oil spill has taken place. One of the kind of oils that block sunlight in the ocean is an oil that comes from home and factory wastes of oil. Home wastes of oil might seem minor from one house but when you calculate it in city and country level, it is very hard to imagine if all got into the ocean. Separating of the ...

In today's world, we use a massive amount of energy every day, nearly 25000 TWh per year. Additionally, a big percentage of this energy is supplied by nonrenewable energy sources, such as Oil (31%), Coal (28.6%) and Natural Gas (21.2%) in 2014. Furthermore, it is obvious that the consumption of nonrenewable energy sources is one of the major reasons for global warming causing oil spills, the abrupt increase in CO2 amount in the atmosphere, deforestation and etc. That's why energy supply is one of the major problems of today's world.

So we designed a keyboard and named it "Click Energy" that could be used as an alternative energy source by storing electricity generated from usage of its own. Placed ...

Many peoples travel through jungles and cross a river for many reasons, like for research and hiking and many others. While doing so, many peoples get attacked by wildlife when passing by because peoples are not aware of which animals are nearby. Animal attacks have been identified as a major public health problem. "Unprovoked attacks occur when the animal approaches and attacks a person(s) who is the principle attractant, for example, predation on humans. In 1997, it was estimated that up to 2 million animal bites occur each year in the United States. Injuries caused by animal attacks result in thousands of fatalities worldwide every year. Some of the world's deadliest animals include mosquitoes.which are estimated to kill about ...

Per billion vehicle miles, 1,011 pedal cyclists are killed or seriously injured, in comparison to 26 car drivers. Around 75% of fatal or serious cyclist accidents occur in urban areas. Around half of the cyclist fatalities occur on rural roads. 75% happen at, or near, a road junction. Riding in the rain is more dangerous than riding in dry conditions for an obvious reason: slippery when wet. The road itself is slicker. Painted surfaces and metal road obstacles are like ice.

This project solves this problem and makes the city safe. This project is about building a manual adjusting protective cover from rain droplets that can be used on any frames for a cyclist to prevent accident during rain.
