One atom thick graphene membranes

Researchers have used the world’s thinnest material to create a new type of technology, which could be used to make super-fast electronic components and speed up the development of drugs. It’s believed this super-small graphene structure can be used to sieve gases, make ultra-fast electronic switches and image individual molecules with unprecedented accuracy. Now an …

Maglev assisted launch

The future goal of maglev launch assist would be to build a space vehicle and maglev sled—together weighing 100 tons—and accelerate them to a velocity of 255 m/s (918 km/hr). The main cost-saving areas would come from reduced fuel consumption and the reduced mass of the spaceship. This idea could be combined with hypersonic skyhooks, …

Trying to clean up coal

the US department of Energy provides background on particulate control research (for making coal cleaner although the goals would still leave coal the deadliest energy source. Coal kills 1 million per year from air pollution) To date, most particulate control technologies have been installed to prevent so-called “coarse” particulates from escaping into the atmosphere. Coarse …

Climate, pollution, nuclear

The Gregory Benford proposal sounds like the cheapest and safest method for climate modification. Of course society should to actually stop making the problems worse as described in Jamais article. But a problem is that most plans from environmentalist fail to recognize the scope of the problems or involve everyone suddenly becoming virtuous. Some propose …
