I am writing this from 20 minutes in the future. I want to pass on my interstellar knowledge.
Like always, I checked my pvponline.com comic and then checked on nuclear fusion.
Check this out!
I remember when Arthur C. Clarke wrote about deuterium ions to fuel spaceships in Hammer of God.
The device, which uses two opposing crystals to generate a powerful electric field, could potentially lead to a portable, battery-operated neutron generator for a variety of applications, from non-destructive testing to detecting explosives and scanning luggage at airports. The new results are described in the Feb. 10 issue of Physical Review Letters.
“Our study shows that ‘crystal fusion’ is a mature technology with considerable commercial potential,” says Yaron Danon, associate professor of mechanical, aerospace, and nuclear engineering at Rensselaer. “This new device is simpler and less expensive than the previous version, and it has the potential to produce even more neutrons.”
The device is essentially a tabletop particle accelerator. At its heart are two opposing “pyroelectric” crystals that create a strong electric field when heated or cooled. The device is filled with deuterium gas — a more massive cousin of hydrogen with an extra neutron in its nucleus. The electric field rips electrons from the gas, creating deuterium ions and accelerating them into a deuterium target on one of the crystals. When the particles smash into the target, neutrons are emitted, which is the telltale sign that nuclear fusion has occurred, according to Danon.
