Chris Moore is a good guy and one very open minded to new ideas and concepts at NASA; the fact that this was picked up by fox news must be that they could relay this to "gas stations" :-)
Now a NASA engineer has come up with a new way to fling satellites through space on mere grams of fuel, tens of times as efficiently as today’s best space probe thrusters.
Instead of using deuterium and tritium as the fuel stocks, the new motor extracts energy from boron fuel.
"And according to his calculations, improvements in short-pulse laser systems could make this form of thruster more than 40 times as efficient as even the best of today's ionic propulsion systems that push spacecraft around. "
while the nuclear reaction seems to be sound at first view, I am not so sure how this would work: "Electromagnetic forces push the target and the alpha particles in the opposite directions, and the particles exit the spacecraft through a nozzle, providing the vehicle's thrust. "
These features lead to a high heat-to-electricity energy conversion efficiency of 5.7% when cycled between 10 and 60 °C, opening a promising way to utilize low-grade heat.
Ever wondered what radiation looks like? If you have, I bet you didn't think it would look as cool as this. This is a small piece of uranium mineral sitting in a cloud chamber, which means you can see the process of decay and radiation emission....
Once I saw a DIY spark chamber in LIP (CERN associated laboratory). It was the work of a bunch of BSc students, they made it all from scratch, so it seemed to be not that difficult to have one at home. Yet another project for the future 'Experimental Physics' stagiare maybe :)
Mining the moon - now we know that the Moon's poles hold millions of tonnes of water ice, firms in the US as well as the Indian and Chinese space agencies are planning to mine this resource and sell it to space missions as fuel.
For the first time, researchers have shown that they can capture CO2 from the air, and convert it directly into methanol, which can then be used as an alternative fuel, as well as for hydrogen storage, in fuel cells, or as a building block for plastic.
Proximity to the transmitter impacts power delivery as follows:
4W delivered to 4 devices simultaneously within 0-5 feet
2W delivered to 4 devices simultaneously within 5-10 feet
1W delivered to 4 devices simultaneously within 10-15 feet
