I have served in the U.S. Navy for over 20 years and I can't sit silent while everyone trashed the Department of Defense for keeping plasma batteries under lock and key.
Whether you fellows gang up on me or not, I am entitled to express my opinion and here it is... Why did we win WWII? Because we had advanced technology (the atom bomb). If we did not use high technology, the war would have dragged on and thousands more people would have died. Hitler also had high tech weapons but he waited too long to use them including the V2 Rocket, the world's first jet fighter ME-262, and the first smart "Fritz" bomb. The Japanese also developed the UL400 submarine that could secretly launch 3 bombers less than a mile from Los Angeles or New York. Fortunately for us, they also waited too long to build them. They were going to drop anthrax bombs on both cities. Millions of Americans would have died. The Technology edge was ours and that is the only reason we won the war. The next big war may be mostly by remote control - another high-technology. China just built their first aircraft carrier but it takes them 2 minutes to launch a single plane while we can launch 4 jets in the same time frame. Why? High-technology.
High technology keeps America safe at home as well as overseas. Read this link to understand what I mean http://www.cfr.org/technology-and-forei ... ies/p14827
In time of war, high technology can spell the difference between victory or defeat. As for these plasma batteries, Imagine a land war spanning a large country like Russia, China, or India. A tank powered by an electric motor and a plasma battery can cross the entire continent of Asia without refueling. An enemy tank would require refueling every 120 miles. Who do you think has the tactical advantage? Ditto for ships and submarines. High technology gadgets may have have both military and civilian uses, but if it can give us such a huge military advantage, it is justifiable to keep them secret.
No matter what your idea of patriotism may be, we all live in an unpredictable world, and war can erupt at any time. Thank God and our technology which has always kept the wars off of American soil and took it to the enemy. So in conclusion, I think these batteries are in the best hands for now.
Freedom is never free. If you are not willing to pay its price then stand in line for it like the rest of the world!
