KiteGenVenture LLC announces the launch of the KiteGen Stem, a massive, 3 MW generator capable of providing affordable clean energy on a massive scale. Using large Power Kites, KiteGen’s generators harnesses freely available kinetic energy from wind, and converts that energy into electricity that is accessible via the grid. Each KiteGen Stem Generator is capable …
Winston Churchill had a project to produce a 2.2 million ton pykrete (ice and wood pulp) aircraft carrier that would have been 1200 meters long and 180 meters wide. This would have made it 3.5 times longer than the US Gerald Ford or Nimitz class carriers which are each about 330 meters long. The final …

A 76 page report by the Center for Budgetary and Strategic Assessments Trends in Air-to-air combat : Implications for future air superiority by John Stillion indicates that dogfighting jet capability no longer matters. Trends from the database of air combat since 1965 show the rise of long range missiles and a steep decline in dog-fighting. …
Louisiana State University researchers could enable the next generation of magnetic cooling technologies, which are simpler in design, quieter and more environmentally friendly than conventional compressed-gas systems currently used. “LSU’s basic research into low temperature physics and materials science has potential applications in areas related to energy, electronics and the environment,” said Michael L. Cherry, …
Engineers at Stanford and the FOM Institute AMOLF, a research laboratory in the Netherlands, have developed a technique that makes it possible to visualize the optical properties of objects that are several thousandths the size of a grain of sand, in 3-D and with nanometer-scale resolution. The technique, called cathodoluminescence tomography, could assist in the …
1. Coulumb Drag Devices: Electric Solar Wind Sail Propulsion and Ionospeheric Deorbiting * Plasma brake thrust is 16 times larger in pure oxygen plasma than in pure proton plasma * There is an altitude dependence. Below 700 km the thrust would continue to increase until 400-500 km (provided there is the right hardware design) Abstract …
The Carnival of Nuclear Energy 255 is up at Neutron Bytes James Conca at Forbes has a positive opinion of the deal with Iran. The agreement framework with Iran was better than James Conca had hoped it would be. The major points are: – Iran will reduce the number of centrifuges from about 19,000 to …
ESAIL: Electric SAIL propulsion technology was presented in late 2014 The ESAIL EU FP7 project (2011-2013) developed laboratory prototypes (TRL 4-5) of the key components of the E-sail. The project involved five countries, nine institutes and had a EU contributed budget of about 1.7 million euros E-sail construction • Positive tethers (10-20 km length made …
Conventional disease treatments such as antibiotics have almost exclusively sought to emulate natural resistance by keeping patients’ pathogen levels as low as possible. This approach has been incredibly successful but has an increasingly serious downside: Any pathogens that survive a particular treatment can defy it from then on, giving rise to new antibiotic-resistant strains. The …
