computersSample Return from hypervelocity flyby’s of Moons and Asteroids

Since the Apollo era, sample return missions have been primarily limited to asteroid sampling. More comprehensive sampling could yield critical information on the formation of the solar system and the potential of life beyond Earth. Hard landings at hypervelocity (1-2 …

cvdCoating that enables two electrons per photon should be able to boost solar cells to over 30% overall efficiency

While today’s commercial solar panels typically have an efficiency of at most 25 percent, a silicon solar cell harnessing singlet fission should make it feasible to achieve efficiency of more than 30 percent, Baldo says — a huge leap in …

chemistryRealization of a micrometre-sized stochastic heat engine

“We’ve developed the world’s smallest steam engine, or to be more precise the smallest Stirling engine, and found that the machine really does perform work,” said Clemens Bechinger, a physicist at the University of Stuttgart and Fellow of the Max …

2011 Global R&D Funding Forecast – Battelle, 36 pages Total global spending on R and D in 2011 is anticipated to increase 3.6%, to almost $1.2 trillion. With Asia’s stake continuing to increase, the geographic distribution of this investment will …

cvdAlgae could replace 17% of U.S. oil imports

A new study shows that being smart about where we grow algae can drastically reduce how much water is needed for algal biofuel. Growing algae for biofuel, while being water-wise, could also help meet congressionally mandated renewable fuel targets by …

cvdAccelerating electrification of transportation with more government dollars or a super-light electrical vehicle strategy

Electric Drive Transportation Association has an eight page document Driving Forward: An Action Plan for the Electric Drive Era which unsurprisingly calls for direct and indirect government subsidies for faster rollout of electric cars. Currently they are projecting 500,000 electric …

carbon nanotubesInterstellar flyby versus deceleration mission considerations

Icarus Project blog discusses the choice between choosing an interstellar flyby versus deceleration mission. Is an interstellar flyby worth the effort ? Project Icarus Study Group decided that we had to go that next step further and consider the difficult …

cvdRice University researchers build microbatteries with nanowire hearts

Rice University researchers have moved a step closer to creating robust, three-dimensional microbatteries that would charge faster and hold other advantages over conventional lithium-ion batteries. They could power new generations of remote sensors, display screens, smart cards, flexible electronics and …
