A briefing about severe storms

submitted by: nsf

Hurricanes, tornadoes and solar eruptions can have profound effects on America's economy, public safety and well-being. A briefing at the Senate Visitor's Center on Capitol Hill, sponsored by the National Science Foundation and the American Association for the Advancement of Science, provided an overview of the current state of storm research.

What it Takes to Build the Next James Webb Space Telescope with Blake Bullock and Scott Willoughby

Northrop Grumman Astrophysicist, Blake Bullock, and Engineer, Scott Willoughby, share what it takes to build the next generation James Webb Space Telescope. Join in to lean about Blake’s job to understand the future and Scott’s role to bring that future to reality at the inaugural X-STEM Symposium in Washington, D.C. on April 24, 2014. The X-STEM Symposium is sponsored by MedImmune and the Northrop Grumman Foundation and is a program of the USA Science & Engineering Festival....

Drones provide wi-fi for disaster relief

submitted by: nsf
At the Smart America Expo, Yan Wan from the University of North Texas exhibited unmanned aerial vehicles (UAVs) she developed that are capable of providing wireless communications to storm-ravaged areas where telephone access might be out. Typical wireless communications have a range limit of only a hundred meters. However using technology developed by Wan and her colleagues, they were able to extend the Wi-Fi reach of drones to five kilometers. In a grant from NSF, Wan is applying...

Multiphase Nuclear Fusion Reactor - Clean and Safe Atomic Energy

submitted by: MFerreiraJr
Conceptually, it has been redesigned to be the most energy-efficient fusion reactor ever. Effectively, a clean, safe, dense and environmentally friendly power source to supply the world's energy needs, with no greenhouse gases, no long-term radioactive waste, low thermal waste, no large land areas, no environmental impact, no interruptions by the weather or time of day, no nuclear meltdowns and no proliferation. It is to be the ultimate energy source, an affordable answer to the world’s...

Phased Electrodynamic Thruster - Safe Nuclear Propulsion in Space

submitted by: MFerreiraJr

Electrodynamic liftoff and propulsion with RF in quadrature for sequential FTL phase variation in order to warp spacetime for generating thrust force in a more energy-efficient way than conventional expelling-mass rockets.
