Re: ripple...
Not to put too fine a point on it, sure would help if you could pulse the system to some extent. Being able to 'syphon off' ripple with a transformer gives you utility power at manageable voltage... FWIW, some trains run on 16.3 Hz... Newly built traction grids (like the High Speed 1 in UK and HSL ...

So, 93143, if a device could be configured such that a non-fusing scattered ion is recovered back into the beam and carries on around again (and repeats as many times as necessary before it gets to fuse), then you'd give such a device some serious attention as a possible means forward for fusion? T...

It would be somewhat like Star Wars. You'd have smaller ships like the Millennium Falcon that can not only travel between planets/objects, but also land on them. Most effective ones though will be like the Star Destroyers--big massive machines carrying massive amounts of stuff, and taking it down o...

Neither methanol nor ethanol can just be "plonked" into gas tanks. Some, yes, but nowhere near all. Butanol however, that is "plonk"able! Reprogramming an engine's ECU (or swapping out the main spray in a carburettor) to cope with the difference in expected fuel/air mixture is NOT a major modificat...

BTW: Turbines can be converted to run on H2, methanol, or any other substance that produces heat. True, but for extended operation at medium altitudes/speeds, which has operational/economic advantages when the origin and destination points on the ground are not well positioned with respect to the d...

Hmm, use CO2 from the atmosphere to produce the methanol and kill two birds with one stone: (nearly) unlimited fuel and (if this actually matters*) net CO2 production drops to near-0. The major problem we're having with that at the moment, is that extracting CO2 at a major scale is difficult. If we...

The idea of using a Polywell as the primary power source for all flight modes, without having to also carry hydrocarbon-fueled turbines, cryogenic chemical rockets, etc. has a lot of appeal. The low-to-mid altitude electromagnetic motors would require Polywell output voltage to be stepped down to a...

Regarding crusiers and amphibious assault ships, would a polywell reactor be cheaper to buy/operate than gas-turbine or diesel turbines + electric motors? Would it require similar or smaller crew sizes? Would the increased time it could run without resupply be operationally significant for the miss...

As for the ability to do this project in a garage, have you seen the EMC2 lab? It is basically a garage. However, the power available to a typical garage falls way short of the requirements to run even a WB6 machine. Well, I think it's more on the scale of a small machine shop, and there is plenty ...

Re: MythBusters Water Heater Rocket
The TV program, Myth Busters, has exploded several hot water heaters and also set off bottle rockets for our entertainment and to bust myths that float around. I think it would be fun to create a myth for them to test. The myth is this: Myth - "A hot water heater properly configured can deliver eno...

OK I got to ask this question. Don't forces such as the electromagnetic force operate by exchanging virtual particles. I think the particle used by the EM force is the photon. Since photons cannot escape from a black hole, how can the EM force operate through the event horizon? Maybe it's because t...

btw, SMPS do operate at a high frequency internally, but what they output is DC. True, but the reason SMPS are used in most electronic devices today is because transformer/rectifier/capacitor arrangements are downright bulky for line frequency. With a higher frequency grid, transformers could be bu...

How does a high frequency power grid relate to a DC grid? Advantages of a HF power grid (with HF, I mean the 400-1000Hz range, like in aerospace): Less losses in transformers and smaller footprints (due to smaller cores), no health hazards from ELF radiation through transmission lines, possibility ...
