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.
