Green energy stocks have been taking a beating the past two years. Penny stocks in general are risky. I believe HSYR is a very interesting stock. The concept is cool, it hits two different green energy markets hydrogen and solar. Currently in the prototype/ conceptual phase. Trying to start larger scale production. When they start distributing government money is when the sector will likely gain steam again. There is a reasonable forecast for money coming in the short to mid term. They will likely get the economy rolling again for the sake of presidential election/ bank stability.
