IMO means "in my opinion". That means it is an OPINION. No trial. No verdict.

Skepticism is always appropriate when someone wants me to invest based on limited information.

One other thing, Pamela Mosier-Boss has worked with Fleischmann for a few years, she is a firm part of the 'cold fusion' camp. And your point? If there is a physical phenomenon underlying all of the anomalous results then why should it matter what "camp" the researcher comes from? Are you perhaps a...

A General Atomics press release in July, 2008 said that the storage subsystem was operational (in Tupelo, MS). They were continuously cycling the system to simulate 250 launches per day.

And the new test facility building is only 5000 sq. ft.

My VA illustration was only to translate MJ into something more people can identify with - you could just as well say 1,000,000V@30A or 100V@300,000A Have you seen a size for a disk alternator? I haven't been able to track down that information. The size quoted is for the entire catapult, which is o...

On a related topic, the new Ford Class carrier will have an EMALS launch system instead of steam catapults: http://en.wikipedia.org/wiki/Electromagnetic_Aircraft_Launch_System Discharge rates of 30+ MJ/sec (100MJ in less than 3 seconds). In VA terms - how about 10,000V@3,000A. I think that solves th...

It is interesting that we have been here long enough that topics are starting to get recycled. Welcome to the web! It truly IS systemic. One anecdote: I have an interest old Case garden tractors. They are unusual in that they use motor oil as the fluid in their hydraulic system. There is a Yahoo gr...
