I have some thoughts in this company.
It is a really great development stage company. The idea of sustainability is a hot button topic. Almost every university and corporation has a sustainability officer and they have quite a bit of pull with in the organization. The University of Florida under the leadership of Stephanie Sims has had its very first zero waste football game. 100K people and all waste was composted or recycled.
Mayor Bloomberg had a sustainability office with multiple employees. They are getting rid of Styrofoam. Mexico city has made plastic bags illegal.
Cities and corporations are scrambling to find ways to get rid of waste and find sustainable sources of energy. Here you have a company that can do both.
It started as a welding company because the regulations on welding fuel are light. Once they have have their foot in that door and are established they can start tackling creating fuel regulations. Have a unit in remote locations certainly makes sense. companies like FUEL and CPST are having recent success for that reason. Another approach is trying to develop other fuel lines in countries where the restrictions are less limiting, which explains the recent PR about Italy.
I think the recent spike is a knee jerk to some PR but in the long term it is a company that has great potential if they can get past the standard developmental stage hurdles like capital and funding without over diluting the shares.
I bought at .23 years ago. It went up to .8O cents and I sold. It did a reverse split and went down, because I don't think it was quite ready for the up listing. I bought back at .6 and then sold again at 1.8 I am only saying so people know how what I just said matches with my investment in the company. When it stabilizes I will buy back in.
