South Africa is undergoing rapid collapse. South Africa used to have abundant energy and could sell energy to neighboring African countries. However, there was incompetent government and starting in 2007 there has been an energy crisis. There has been chronic shortages of electricity. This has reached the level where there are a constant schedule of …
1. Universe Today – ‘A City on Mars’ is Elon Musk’s Ulitmate Goal Enabled by Rocket Reuse Technology How often will SpaceX recover the rockets ? “I think that we’re going to get quite a few rockets back, so I imagine we’re going to have a whole fleet of booster rockets accumulating quite rapidly because …
In a Danish television interview, Tesla CEO Elon Musk said the company will steadily increase the range of its electric cars over the next few years. In the interview (the relevant section begins at 6:22), Musk said that Tesla could increase the range of the Model S to 1,000 kilometers (621 miles) “within a year …
During the past 15 years, China’s ambitious naval modernization has produced a more technologically advanced and flexible force. The PLA(N) currently possesses more than 300 surface combatants, submarines, amphibious ships, and missile-armed patrol craft. Although the overall order-of-battle has remained relatively constant in recent years, the PLA(N) is rapidly retiring legacy combatants in favor of …
Dwave quantum computers at 512 qubits should run some algorithms that achieve a speed advantage I’m some cases. However, there are a lot of supercomputers and a petaflop scale machine could come down to $10 million prices in the next year. The main utility of the quantum computers will be to run unique quantum algorithms …

Koroteev President of Russian Academy of Cosmonautics 2010 (19 pages) The presentation discusses nuclear power sources for space up to 1 megawatt for flying to Mars, moon base power and for orbital tugs. …
Ad Astra Rocket Company and NASA Johnson Space Center (JSC) have signed a Support Agreement to collaborate on research, analysis and development tasks on space-based cryogenic magnet operations and electric propulsion systems currently under development by Ad Astra. The Support Agreement is the fourth entered into by the parties under an “Umbrella” Space Act Agreement, …
ReWalk can help paraplegics to stand and walk – using crutches for stability – when they lean forward and move their upper body in different ways. Regular usage of the device, which costs about $100,000, would prevent costly complications that often arise in people who can’t walk, including pressure sores and urinary, digestive, circulatory, and …
The Sixth carnival of nuclear energy is up at NEI Nuclear Notes site This site provided the article which used energy statistics for OECD countries over time which show that solar and wind have been built far slower than nuclear energy. This shows that Mark Jacobson is wrong in his misleading looking at pieces of …
Peter Weyand and colleagues have published a paper which details how human running speeds of 35-40 mph may be biologically possible Peter Weyands estimate of the fastest speed a human can run has been covered here before (he had indicated that 45 mph is possible for a modified human shaped runner). The newly published evidence …
MEMS used to detect the presence of the Casimir Force Scientists at the U.S. Department of Energy’s Argonne National Laboratory are developing a way to control the Casimir force, a quantum mechanical force which attracts objects when they are only a hundred nanometers apart. Recently Ames Lab calculated that metamaterials could be used to make …
