Re: Thought Experiment Regarding Breakeven

To give my own version of an explanation: Currently existing fusors are primarily useful as machines that convert electric power and deuterium gas into a small amount of neutron radiation (along with a bunch of light, heat, and X-rays). This is a very useful thing, since most other ways of getting n...

Re: NIM system or Digital Detector

I think that conventionally, software-defined radio is considered to *not* use conventional electronic frontends, but rather an incredibly thin frontend that is the absolute minimum to translate digital date in a blazingly fast DSP into an analogue signal.

Re: Fusor construction questions

Looks pretty impressive.

Re: 2200 l/s turbos
