5. Orbital Hub looks at PROBA-2, which is part of an ESA program called In-Orbit Technology Demonstration Program, which is dedicated to the demonstration of innovative technologies.
Among the new equipment and technologies demonstrated by PROBA-2 are new models of star trackers, GPS receivers, and reaction wheels, a new type of lithium-ion battery, an advanced data and power management system, composite carbon-fibre and aluminum structural panels, and magnetometers. PROBA-2 also hosts a digital Sun-sensor, an experimental solar panel, and a xenon gas propulsion system.
6. 21st Century Waves talks about the ambitious Japanese space bases solar power plans.
Japan announced their spectacular new $ 21 B space-based solar power initiative. According to Japan’s Institute of Energy Economics, the Mitsubishi Electric Corp. and IHI Corp. will lead a 15-company team that will build the first major solar power plant in space. Via microwaves, it will eventually beam enough energy back to Japan for nearly 300,000 houses.

Propulsion Based on Exploiting Mach's Effect
22. A second article with answers to various questions in comments on mach effect propulsion.
Questions spurred from the first nextbigfuture article on mach's effect propulsion which has an interview with Paul March
Mach Effect investigation could be a path to the unification of general relativity and quantum mechanics. Here is links to abot 20 hours of Stanford lectures on General relativity and another 20 on quantum mechanics plus a short video from one of the investigators of mach's effect for potentially revolutionary propulsion.
If Mach's effect can be used for propulsion as envisioned then what has been envisioned in terms of space travel in capabilities in Star Trek and even possibly wormholes for Faster than light travel and communication becomes possible. The work is based on solid General Relativity and Quantum Mechanics and understanding of inertia and the experiments are being carefully conducted. Success development would be a candidate for one of the greatest accomplishments of humanity.
