Take a look at Envision Solar EVSI. Solar EV charging for vehicles. Nice clean cap table. Can be setup in minutes without permitting and connecting into the grid. Company finally has access to real capital (for the first time) after raising $12M back in April. One of my largest small cap holdings. Not very liquid. Think its at least a double sometime this year.

Best of luck and have a safe 4th of July.
