It has been years. What I like is unlike so many OTC. They clearly have huge revenues they can make. Seems the product will pay for itself by saving oil that otherwise be wasted. Also unlike other OTC. While they have been doing this for years. No hype pr's and massive dilution. Seems owners have held onto the shares. If this contract happens. Just this one. Revenues be close to $1.00 a share. Any huge volume like years ago. This hits $2.00 or more same as then in a day. IT been moving up nice and steady.
