NASA announced it was seeking proposals for mission concept studies of a high-power solar electric propulsion (SEP) system that could be used in a "space tugboat." Such a ship would be used ferry payloads in low Earth orbit (LEO) into higher energy orbits,

here we go - a quite significant step in getting SPS off the ground !!

Idian government approved $19 billion plan for solar energy project

new article about Japanese SPS plans ... in general all that is written is actually also true ....

not for space but the air breathing battery still is a nice concept - would make robots more "human" if they have to breath :-)

saac Asimov's predictions of the year 2014 back in 1964.. Truly amazing to read how close his sharp mind turned out to be at that time (cold war, Yuri Gagarin just went into space and Fortran first appeared 7 years before). The last prediction also came true I think, however the solution was not psychiatry.. instead we invented Facebook, Twitter and Instagram

Also, he predicted that solar power stations would power the places on earth where solar power nor fission (?) would be available... Not there yet

Nice link and clear overview! I like the point raised about 1000 man in space, even when including automation (as far as they could envision at the time). Now that is a future of the space industry and permanent habitation of near-earth orbits! In fact, I can envision just two reasons maybe, power and the hotel industry

Commercial project for wearable solar cells by 2015 ...

not latest news but still, he is probably the most high profile SPS advocate out there

always said so...

some biomimicry used in energy systems... maybe it sparks some ideas

not much new that has not been shared here before ... BUT: we have done relativley little on any of them. for good reasons?? don't know - maybe time to look into some of these again more closely Energy Efficiency( Termite mounds inspired regulated airflow for temperature control of large structures, preventing wasteful air conditioning and saving 10% energy.[1] Whale fins shapes informed the design of new-age wind turbine blades, with bumps/tubercles reducing drag by 30% and boosting power by 20%.[2][3][4] Stingray motion has motivated studies on this type of low-effort flapping glide, which takes advantage of the leading edge vortex, for new-age underwater robots and submarines.[5][6] Studies of microstructures found on shark skin that decrease drag and prevent accumulation of algae, barnacles, and mussels attached to their body have led to "anti-biofouling" technologies meant to address the 15% of marine vessel fuel use due to drag.[7][8][9][10] Energy Generation( Passive heliotropism exhibited by sunflowers has inspired research on a liquid crystalline elastomer and carbon nanotube system that improves the efficiency of solar panels by 10%, without using GPS and active repositioning panels to track the sun.[11][12][13] Mimicking the fluid dynamics principles utilized by schools of fish could help to optimize the arrangement of individual wind turbines in wind farms.[14] The nanoscale anti-reflection structures found on certain butterfly wings has led to a model to effectively harness solar energy.[15][16][17] Energy Storage( Inspired by the sunlight-to-energy conversion in plants, researchers are utilizing a protein in spinach to create a sort of photovoltaic cell that generates hydrogen from water (i.e. hydrogen fuel cell).[18][19] Utilizing a property of genetically-engineered viruses, specifically their ability to recognize and bind to certain materials (carbon nanotubes in this case), researchers have developed virus-based "scaffolds" that

More information on the future of UAVs and the space industry.

Japan has started construction of two floating solar power plants, which will become part of a huge, 60 megawatt floating renewable energy network.

They should probably buddy up with the wave energy dudes and create the ultimate reneweable energy plant

Hurry up if you want Solar Power generated from the Sahara desert! Others think different

another one on SPS

We report a new record power conversion efficiency of 3.5% for inkjet printed

unexpected indeed .... have to check to find out more ... (LS)

In 10 years... Sorry Leo.
