Those of you checking the URL will notice that its not NASA.gov, but the address comes from the NASA “Tech Briefs” email that they send out to alert people of space related technology spinoffs that are going “mainstream.” (You can subscribe to the email by sending an e-mail message to the address Listserv@listserv.abpi.net with the text SUBSCRIBE Insider Firstname Lastname as the only text on the first line of the message body.)
