Interesting that there are about 5000 patents which have been sequestered by Uncle Sam.... most probably relate to arms and explosives... but...
Wonder how many of them related to energy? Notice that DoE puts in about 3-4 orders in some years - now, just what kind of invention could be seen as a national "threat" by DoE ????
