They sold a DEMO Fuel cell to the Indian DRDO and never sold them anything else ever again.
S4W - went nowhere, it is a nothing company with a website they never updated.
VOXX - ? Nowhere to be found with a bodycamera..supposedly was availble in Late Spring - never to be seen, then fall of 2017 never to be seen.
XNRGI - not even the name of the company is trademarked. They have a twitter account with no tweets, a Facebook account with nothing in it. A website no one can access.
Nothing going on here for another year. Same as 2006, 2007, 2008, 2009, 2010,2011, 2012, 2013, 2014, 2015, 2016.
