Making 10% of Light Speed Beam Propulsion More Practical With Neutral Beams
The conventional means of collecting and redirecting solar sail light uses a metal-coated polyimide film but this is sub-optimal and unstable because the very large and very thin sail must be rapidly slewed away from the sun line for navigational purposes. Stability rigging and attitude control devices add mass to the sailcraft, thereby reducing the …
The NASA Innovative Advanced Concepts funded a phase 1 study by Geoffrey Landis for power interstellar fly-by probes. Launching ultra-miniature probes to fly past an exoplanet a nearby star using a laser-pushed sail is now being seriously discussed as a mission, primarily by the “Breakthrough Starshot” program. Breakthrough Starshot has US$100 million to initialize research. …
I was debating Ned Ford about solar, wind and nuclear energy at Quora. My energy answer on Quora was about how nuclear power was still being more economical than solar and wind. Ned is a volunteer conservation chair at a Sierra Club chapter. Ned believes many popular myths about solar, wind and nuclear. Solar and …
Elon Says More Tesla Factories Will Be Made in China
Carbon Nanotube Thin Film Patch Antennas Viable for 5G, Drones, Sensors and IOT
Low-speed electric vehicles (LSEV) sold 75% of the unit volume of standard electric vehicles in 2018. About 1.5 million units in China during 2018—equal to about 6% of “conventional” vehicle sales for the year. For a bit of perspective, the entire global sales volume of standard-sized EVs was about 2 million units in 2018. Sales …
Space Gets 100 Times Cheaper By 2023 and We Will Get Moon Bases and More
Graphene has a lot of potential because it can be the strongest material and has many other exceptional characteristics. There has been a lot of research around the material since 2004, when Professor Sir Andre Geim and Professor Sir Kostya Novoselov of the University of Manchester discovered and isolated a single atomic layer of carbon …
