Peamp I don't think trying to do new breakthrough technology is as easy as the casino, PR sporting event and fast lane life of the OTC makes it out to be. It just offers an easier way to raise money and make contacts than doing it privately. But takes everyone for a ride in the process. Since the OTC is a casino like ride activity. A PR sporting event. Investors more of a ride than management. But must be for management too. If PWTC was a private company they would probably have a lot harder time to raise money, make connections, get exposures and taken serious. But either doing it going public in the fast lane of the casino OTC or the slow concealed less money plays private way, there is no gurantee of success. However it is easier for PWTC to raise the needed money on the OTC especially if can't get it from partners or alliances. And it does seem that PWTC has the battery done. But far from industry worthy and ready yet. The new lead paste doesn't seem to be needed and if it can make the battery even better it can come later in a better version. What is more importan than the paste is the new structural complexity. And that seems done if not tested ready in all aspects of wear and tear prime time use..
All in my honest but greedy biased guesses and opinions.
