Why wont GRC publish information on their energy balance? what are they hiding? No one will buy anything unless it has a positive energy balance. Go ahead blow that off with your crude and ignorant BS about my machine dummy. I am proud off our energy balance and efficient engineering, modular design, and cost effective operation. As for the board genius Knowit all, posting 3 times is against board rules and only underscores his desperate attempts to discredit. DM must have been asleep on that one Huh? I wonder if I am writing to the 3 stooges. Come on bash bash bash It is doing wonders for me. I get emails from engineers across the world and they all ask, why is GRC using klystrons, But I guess the inventor of the Hawk 10 knows best Huh Hawk.
