Water is very critical for survival and that is why you hear often on water saving awareness and researches that could help on saving water from big consumption to small consumption in households. The problem of water wastage is not because of awareness because people know when they waste water, they just do not have a habit of saving them. One of the places where water is wasted big time is in household activities like washing your dishes, your hands, brushing your teeth and other similar activities that require us to use the sink multiple times in a very few period of time. On average, about two gallons of water flow from a faucet each minute. Something as simple ...

Ambient Updraft Power Converter

Air moves up because of relative heat and density. Density is caused by the distance from the center of the earth and the amount of air on top of the air. The Ambient Updraft Power Converter (AUPC) uses both of these means with a vertical duct. Air is more dense at the bottom of the duct than it is at the top of the duct. The air is cooler at the bottom of the duct and warmer at the top of the duct. The density and the difference in temperature both move the air up. The AUPC also uses a duct with a larger diameter at the top and a smaller diameter at the bottom ...

Here is proposed a new control framework for converters of renewable energy sources, based on choosing their operation mode – grid-forming or grid-following depends on the dynamic properties of a power system. Accordingly with the proposed definition of the power system’s dynamic stiffness (DS) are defining its direct (DDS) and quadrature (QDS) components. The values of these components let us estimate a disturbance’s impact on a power system at bus i, and also the power system’s inertia around bus i at this disturbance. So, using the DS we can estimate the dynamic properties of a power system in real-time, and locally for each need bus. Based on this information, proposed different applications DS for resilience planning at increasing renewable ...

The recent coronavirus outbreak worldwide created an emergency involving all countries In order to help fight the virus one of the most important early activities is to detect potential carriers through the body temperature monitoring, by individuating those with body temperatures higher than 37.5C.

In order to do a mass screening in short time and at a distance we are proposing the following system:

-A carrier
In our case an unmanned platform, a small airship (15/20mt) that can fly permsnently powered by a PV film to generate solar energy for its electric engines during the day and producing hydrogen for night utilization through a fuel cell system

-A sensor
A powerful infrared sensor, similar to those utilized in airports ...

Ever since the invention of electric power by Serbian-American inventor Tesla Nikola, electric power has been very critical for survival of human beings. Whether the source of the electric power supply is renewable or nonrenewable, you often hear the concept on the awareness of conservation of electric power or electric power saving and researches that could save electric power consumption. One of the places where electric power is wasted is at household level activities like overcharging your devices of any kind. Householders waste £134million a year overcharging gadgets such as mobile phones and laptop computers, according to a study in the UK. One in five Britons leave their devices plugged in once the battery is full because they are ...

As coastal cities and communities continue to grow, the demand for physical, earth-fast real estate has increased. In many areas, the ability to meet the demand is strained due to consistent flooding. The creation of new, buildable land can also lead to the infilling of coastal wetlands and habitat destruction. Moreover, the demand for where parking is needed may change for emergencies, certain seasons, and special events.

The Floating Parking Barge for Vehicles provides increased parking capacity for a particular area, and can be moved under its own power or by tugboat. More importantly, the invention will also be utilized in various emergency applications, where land-based parking is unavailable or unfeasible. This is especially true when delivering aid after ...

Railway hawkers are people who carry snacks on trains. They carry the snacks in trays which they hold in hands. Being heavy it’s most likely that their hands will ache at some point in time and it's not even comfortable to carry the tray in a crowded train. To overcome this some of them use self-originated techniques like using a hand towel. Tying the tray with the cloth around the neck. As the problems might look small but could impact more on the human body. The weight of the tray and holding it inappropriately can lead to physical health issues body disorders and many more things. As this business is carried out in crowded trains the hawkers need to ...

Recently I met someone in the street who is in need of something but could not manage to explain because she was deaf and anyone in the street did not know any sign language. She asked me if I have any pen she could write with so that she can communicate with people for her urgent need. Sadly I did not have any so we spent considerable amount of time looking for one. Starting from that point I kept thinking in this technological age, why have not we developed a way that enable deaf people can speak? So, I designed a simple structured device with complex working function that can enable deaf people speak with sound so that any ...

According to some emerging evidence published in the journal by scientists at Princeton University, University of California Los Angeles (UCLA) and the US research agency, the National Institutes of Health (NIH) - though not in significant quantities, the Coronavirus can be airborne. Meaning, it may also remain airborne in much tinier droplets in form of “aerosol" (virus remains suspended in the air in very tiny water droplets, smaller than the ones coughed or sneezed long after larger droplets have fallen to surfaces or been breathed in). While it is in the air in droplets, an uninterrupted droplet from a sneeze can travel around 60 meters.

To establish protection mechanism in Coronavirus hot zone places besides wearing protective gear, we ...

With viruses being a major problem today I designed a low cost, easy to produce personal protection suit that would allow people to still move about and perform some functions without exposing themselves to the hazardous environment we have today and in the future.

I envision my design being constructed of clear vinyl in 4 basic sizes. The design can be modified to make the suit more comfortable to wear and make the adjustment with 3 inch clear vinyl tape. I specified rubber gloves and replaceable footwear. Normal cloth cloths could be worn inside or outside as desired. Medical entry pockets can be included where necessary for medical assistance. The suit being vinyl makes decontamination easy. Clean filtered air ...
