NASA's Langley Research Center has developed an inexpensive, long endurance vertical takeoff and landing UAV. It is capable of flying for 24 hours, landing in a 50 x 50 zone, and can be loaded into the back of a cargo van for easy transport. In addition, it can land in an either horizontal or vertical flight configuration. The vehicle can be used in any application where UAVs are needed to take off from, or land in, an unprepared landing area.

Benefits

•Can take off and land vertically, as a helicopter would, without any support equipment such as a catapult launch or capture nets
•High aspect ratio wings result in 24 hour endurance which is unmatched in the industry

Every year, air pollution causes the premature deaths of between 5.5 million and 7 million people, making it more deadly than HIV, traffic accidents and diabetes combined. The majority of these deaths — about 4 million — are caused by indoor air pollution, primarily in developing countries. But it takes a toll in developed countries as well. In Europe, for example, air pollution shortens the average life expectancy by nearly one year. Worldwide, more than 80 percent of people living in urban areas breathe air that exceeds pollution limits advised by the World Health Organization (WHO).

Utilizing a double-blind study, the researchers studied the impact of ventilation, chemicals, and carbon dioxide on workers’ cognitive function in representative ‘non-green’ vs. ...

How it works: The AirWedge II pulls air under the Class 8 trailer (18 wheeler), forcing the air under the trailer axles and out the rear creating a Bernoulli slipstream that pulls the drag from the rear trailer doors.

Why it is innovative: Trailer skirts are slabs of plastic mounted on the trailer sides that seek to block airflow from flowing under the trailer. The disadvantage is in the most common driving condition, wind from the side, a skirt slows the airflow achieving between 2% and 3% mpg increases.

The patented AirWedge II is similar to an airfoil. The AirWedge II uses the under trailer airflow to control trailer flat plate drag operating from a direct headwind to ninety ...

In highly agricultural areas where fertilizers are commonly used to support growth of plants there is also a problem with the fact that not all the fertilizer could be absorbed by treated plants. Because of rain or other weather related effects fertilizer gets access to rivers. Then it starts to be very concentrated when a river flows into lakes. In result condensation of manure is so big. Because of that it allows to grow unwanted algae. The effect of growth of these plants is very harmful for ecosystems of lakes and it affects significantly the quality of water.

Concept solution
I would like to propose the following idea that reduces the effect of unwanted growth of algae. In order ...

We have developed a groundbreaking power system that leverages current MIT research to turn scrap aluminum into a highly efficient, safe fuel source.

Aluminum has an incredibly high energy density, double that of gasoline and an order of magnitude greater than lithium-ion. However, an oxide layer forms on its surface when in contact with air, preventing it from reacting. Processes have been developed to circumvent this in order to utilize this energy density in applications such as rocket fuels, but they are very dangerous and create serious risks of combustion.

In recent years, students at MIT have developed a method for safely activating aluminum by treating it with 2% gallium and indium. This treatment bypasses the oxide layer on ...

Abstract - A system for generating mechanical and or electric power using low grade thermal or electro-magnetic energy reservoirs, such as air, water and incident light to fuel the power generation cycle. The system performs in a manner similar to a refrigeration cycle.But the system differs from a refrigeration cycle because the system extracts the thermal energy absorbed from the reservoir and energy of compression using the turbine/motor. Greater than 105% of the energy for compression will be available for the system when the appropriate system geometrics are ...

Closed loop system for recovering ammonia from wastewater

NASA's Kennedy Space Center (KSC) seeks to license its Ammonia Recover System for Wastewater to industry. The Ammonia Recovery System for Wastewater was developed for potential use as part of the Environmental Control and Life Support Systems (ECLSSs) on the International Space Station. The system uses an affordable media that is highly selective for ammonia. Ammonia concentrations in wastewater as high as 100,000 ppm can be reduced to less than 1 ppm. Following treatment, the media is regenerated for reuse in the system and ammonia is captured as a by-product.

ECLSS conditions require low power usage and the avoidance of high temperature and pressure operations. State-of-the-art for ammonia removal techniques involve ...

Commercial nanoelectronics device manufacturing is very expensive, with fabrication facilities costing up to 17 billions and requiring massive quantities of water and power. The cost of the next fabrication in Taiwan is projected to reach $20 billion. Meanwhile, the Internet of Things (IoT) where a network of physical objects embedded with sensors, electronics, software and connectivity has an estimated market of $11 trillion over the next few years. These IoT market projections will be significantly accelerated by the availability of ubiquitous low cost sensors which will be difficult considering the current cost of fabrication.

This new disruptive technology will enable the printing of nanoelectronics at the same scale but at a facility that will cost 100 times less than ...

The engine consists of two blocks. Number of blocks may be from one to the reasonable quantities (like 3, 4, 5 etc.). In this case, submitted an engine which consists of two blocks. Every block consist of two pistons (the black one - main and the red one-additional), and two valves. The first valve provides the intake of the fresh air-gas mixture into the volume above the additional piston. The second one provides the transfer of the compressed fresh air-gas mixture from the volume above the additional piston into the volume above the main piston and separates volumes above main and additional pistons after the ignition of the fuel in the volume above the main piston. The suggested design, ...

This is a new design that takes advantage and merges two very well-known designs.

Airfoil wings make lift by changing the direction and pressure of the air that crashes into them as they move through the sky. The spinning cylinder wing design, using the magnus effect, has many advantages over traditional airfoils but also some disadvantages. This design is a type of merger of these two known technologies in such a way as to make use of the advantages of both while eliminating the disadvantages. Some of the advantages are: More wing lift and less drag!

Instead of the solid, rigid, stationary design of a traditional airfoil, the Magfoil has an outer skin that rotates. In other words, as ...
