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 ...

OVERVIEW
We rely on communication to interact with the world around us. Typically, we communicate through visual and auditory sensory inputs; however, due to cognitively demanding tasks or physiological impairments, these inputs may be preoccupied or unavailable. The MISSIVE (Multi-sensory Interface of Stretch, Squeeze, and Integrated Vibration Elements) is a novel, wearable, haptic communication device that transmits language to users through the sense of touch. The device is worn on the upper arm and made up of three types of haptic actuators, each of which is capable of rendering either squeeze, stretch, or vibrotactile sensations. Using combinations of these sensations, we developed a large set of distinct, multi-sensory cues to serve as a “haptic alphabet.” We validated the use of ...

Cleaning the shower should not be hard for anyone. A Teflon- or ceramic-coated shower would repel water and dirt from the surface walls. Who wants to spend an hour scrubbing dirt from scum ridden walls? A shower is a space in the bathroom for humans to use for personal cleanliness. Why use the area for a nuclear attack on the walls with a scrubbing chemical bomb? Life is too short for that. Help keep the sewer free of chemical cleaners. Manufacture a shower with slick walls where no soap scum can dwell and no bleach is needed to kill the stains.

The coating should cover acrylic or fiberglass surround pieces for a three-piece stall or a preformed one-piece stall. ...

Enriching work efficiency and rate of production, reducing production costs and workload, refining services and customer relations, maintaining security on a vast scale are a few of the top reasons why the Unmanned Aerial Vehicles (UAVs) industry is promising.

To gain an insight, in consequence of the continuous population growth- Egypt leads its way towards sustainability through the investment in its vast territories. In a world free of UAVs technologies, quality assurance imposes the existence of a complex infrastructure, powered by thousands of employees who will be in charge of observing these landscapes, collecting data, examining the overall conditions, predicting potential crisis and acting upon which - if any occurred. On such a large-scale project, a lot of workload ...

As the global population continues to grow every year, so too does the demand for agricultural products. To continue feeding the world without damaging the environment is one of the greatest challenges faced by society, and can only be achieved by increasing the efficiency and sustainability of agricultural production.

This project is about filling the gap between modern farming technology which requires skill, more cost and higher tech and traditional or ancient technology still widely used in many countries of the world which does not require much skill, labour-based and lower cost. The mechanism of semi-automated farming technology is very simple. First, there is a C- channel structure (the green structure) fixed with the farming ground at the side ...

Please find hereby a system of quick changing superstructures on the vehicle chassis of any manufacturer. Your vehicle can change its application in about 3-4 minutes. For example, a dump truck turns into a tank truck for liquids, or a concrete mixer turns into a platform for transporting containers. There may be more than 30 types of superstructures for different purposes. The entire hydraulic system is built into a special frame that is mounted on top of the vehicle chassis (frame). Any superstructure is fixed to the vehicle by means of reliable locks, which will not allow to unhook during the movement and operation. This project has a wide area of application. For example, the farms where it is ...

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 ...

BRAILLE II implements a cheap, simple and portable multi-line Braille display compatible with any touch screen device, allowing low-income blind users to get access to education, public services and work opportunities easier than ever.

The device implements a mechanism that can generate Braille symbols and automatically slide them across user's finger, imitating the tactile feedback they would get reading ordinary Braille text. User's other hand is used to navigate across the surface of the screen of, let's say, a tablet. Said tablet reads touch coordinates and transmits a corresponding letter to BRAILLE II which is subsequently displayed to the user. Any graphical or console interface can be made available in Braille just by sending corresponding symbol commands to BRAILLE ...

The problem of the increase of greenhouse gases in the atmosphere is one of the topics discussed almost daily because the effects on the climate are of daily discussion. It is time to move on to remedies. In practice, remedying the problem of excess CO2 with recapture, using devices installed directly in new-generation cars. If my idea comes to practical implementation, hundreds of millions of electric cars will take over CO2 recapture in the near future. The car will turn from pollution to cleanliness of the atmosphere. The direct capture technologies from the atmosphere are almost mature and in my project they must be distributed to the cars to act on a large scale. Once the task of CO2 ...

Explaining how my device does the following:

a. Monitoring C02 levels in the immediate vicinity of the crew member, preferable near the mouth and nose:
The Proposed personal CO2 monitor is a portable, wearable Bluetooth device which is clipped to the upper body clothing of its user. It can be built with commercial IR sensors like the Arduino Analog Infrared CO2 Sensor or most preferably the “CozIR sensor” which are lightweight and use significantly less power so can be battery powered only needing to be charged after weeks or more of usage.

b. Is not obstructive so as to minimize crewmember discomfort and distraction:
The device is designed to have a small form factor, it is attached to the ...
