Clearly more than one person. Ron, I know you're a partisan for Dr Woodward, but crying "bullshit" every other post doesn't really help make your point.

Re: EM Drive

Just to clarify something, which illustrates how terminology misleads, the quantum information that black holes may or may not erase is quite different to the information which DNA stores and which is generated via the process of natural selection acting on 'random' variations in a DNA sequence, jus...

Re: em drive

Glad someone has read Gerry and Jeff's preprint. I sent the link to Sonny White & Paul March, but haven't yet read it myself. It seems either Gerry & Jeff have misinterpreted what White's testing with his test articles or they've provided a useful analysis of the "null hypothesis" - that a given tes...

Re: Another mechanism demonstrating superconductivity w/carb

Yasushi Kawashima lodged a Patent back in 2009 on this very same "discovery" so I'm thinking 4 years without replication is a bit odd for something so "revolutionary"... Patent US20110130292 ...but it does seem easy enough to replicate. Just seems weird that Kawashima has been so quiet about it unti...

Unfortunately the article does not mention the starting efficiency or the ZT figure of merit so is difficult to understand if it is something that might have some real world application or just material useful for research use. TAGS 85 is a first generation thermoelectric material that can be manuf...

Cryogenic Thermoelectrics?

Forgive my ignorance of thermoelectric physics, but could a solid-state cryocooler be created using high ZT materials?

Re: Hitching a Ride on a Magnetic Bubble

The Mag-Beam is definitely a better option for a lot of reasons, but manipulating plasma to create a defense against the solar wind and cosmic rays is a worth-while goal of Winglee & co's research. Though both Polywell and Plasma-sails use plasma there really isn't a lot of technology cross-over. Th...

Invisibility

Considering everything we're learning about modifying light, surely if ETIs have mastered interstellar travel, then they'd be able to go to-anf-fro unobserved - unless they want to be seen. But ETIs don't have to come from other star systems - they might have lived here for billennia already out in ...

Where does the energy come from?

Hi Paul March & all

One question I've wondered since Woodward's ideas first surfaced was just where does the kinetic energy of the space-vehicle come from? Does his theory actually explain that? Is it conserved overall?
