In a “Loss of Coolant Accident,” such as those which occurred in TMI and Fukushima, after minutes without effective cooling, reactor cores have overheated and melted, leading to leakage of radioactivity to the surrounding environment from the larger outer Concrete-Containment-Building. Causes include internal hydrogen explosions; steam over-pressurization of the Containment-Buildings secondary to emergency-infused cooling-water being flash-vaporized upon contact with an over-heated inner-steel reactor-vessel-core during a non-design basis accident (such as occurred at Fukushima), or possibly even from a single broken internal high pressure steam pipe (such as occurred at Chernobyl). The pressurized-steam and the volatile radioactive elements released into ...
We hereby give you a defense vehicle which is equally powerful to a tank, but compact and stealthier than it. It will moreover look like a motor bike. We use mono caterpillar track to drive the vehicle, but the tracks are fit with rubber pads with strong grip threads in order to nullify the sound made by the tracks and to ensure its maneuverability on all types of land.
In front a big wheel is provided with grip threads. This wheel is used for steering the vehicle. Articulated steering is used for steering this vehicle. The steering wheel is ...
Far-infrared and submillimeter astronomy is a hot research field. The relative weakness of this radiation requires telescopes to use cryogenically cooled superconducting bolometers and associated transmission lines and processing equipment. Literature examination suggests that considerable time and care is spent on wiring and interconnecting systems to avoid failure points.
We propose a different thermal sensor, covered by submitter's US patent 7,586,106: a low thermal mass multi-pixel thin planar film, unwired, which generates, when absorbing said radiation and interrogated by light of suitable wavelength, a fluorescence of wavelengths shorter than 1.0 micrometer. Refrigeration requirements would be drastically cut: processing light ...

Ozone layer depletion is a well known problem. Not necessary to write too much about it. If You need more info, please visit the NASA web site, You will be informed.
I'll write about the solution.
When I saw the latest news from NASA on how fast the climate problem is developing, I made a decision to act and give my personal effort.
I have had this idea for years, but technology is now good enough for this application. Now you can buy ozone sensor for 1.28 - 2.5$. Device is lifted into the stratosphere by ...
The concept of this vest is to have a passive cooling system based on two phase changing heat transfer features; heat pipe technology for high level heat transfer and phase changing materials for heat storage.
The benefit of such concept is to have a passive cooling system, based on known technologies, which removes heat from a human body.
The body heat is transferred by conduction to the flat heat pipe evaporator. The working fluid in the heat pipe changes from liquid to vapor (latent heat of vaporization) and flows to the condenser side. While the vapor condenses back to ...
Potentially Hazardous Asteroids Space Telescope (PHAST), a proposal for asteroid detection, tracking, and characterization.
Near-Earth asteroids (NEAs), also called near-Earth objects (NEOs), orbit the sun, like all asteroids, but their paths bring them “close” to Earth (within about 45 million kilometers). Scientists estimate that they've found about 95 percent of the potential "civilization-enders" .Until today 1488 of these NEOs have been classified as Potentially Hazardous Asteroids (PHAs). This specific definition defines any asteroid with an Earth Minimum Orbit Intersection Distance (MOID) of 0.05 AU or less and an absolute magnitude (H) of 22.0 or less. The biggest challenge now ...

Unmanned Aerial Vehicles (UAVs) are aircraft without a human pilot aboard. Flight is controlled autonomously by on-board computers or manually by remote control in a ground station. And an Airship is a type of aerostat (lighter than air aircraft) that can be steered and propelled through air using rudders and propellers. They don’t use aerodynamics unlike aircraft. But can these Airships be only made in the conventional ways as they are now done? Isn’t there any way we can make the Airship such that it can be driven on its own? Now, what if we are able to incorporate an ...
The Ram Accelerator, invented in 1983 at the University of Washington, is a novel mass driver consisting of a long straight tube filled with combustible gaseous mixtures such as hydrogen and oxygen. Upon ignition, an aeroshell “surfs the combustion wave” with sufficient velocity to exit the atmosphere. At velocities of ~3km/sec to 8km/sec, (1.86 to 4.97 miles per second), payloads are deployed into Low Earth Orbit Networks within minutes.
Increasing tube size yields proportionate payload and fuel. In gun type devices the energy source is concentrated at the breech while the Ram Accelerator’s distinguishing characteristic is its energy source, ...
What problem does your design idea solve?
Rotary wing platforms are flexible and powerful solution for a range of missions such as medical evacuation, rescue, courier and transportation. However, these aircraft are in danger to collide with terrain features, obstacles and other flying aircraft, especially in bad visibility conditions.
Unmanned rotary wing platforms are the next big thing in delivery service. Indeed, there are yet legal and regulatory difficulties, but the future is out there. However, autonomous navigation and operations is yet a big challenge.
What are the potential benefits?
Imagine a world where unmanned aerial vehicles delivering goods ...

Rapid Forest Fire Extinguisher
Fires in dry arid forests start very quickly. Even if these fires are detected quickly, by the time resources are deployed to the fire, the fire could already be out of control. Traditional methods for controlling such fires involve dumping water from a nearby water source by helicopter, aircraft or people with tools – sometimes with deadly results. Moreover, the trip from lake to source loses precious time needed to fight the fire.
This invention involves using a large multistage bottle rocket that has a long range. The bottle rocket features a finned guidance system, ...
