SmallCapInvestor.com wrote up a nice research report (it’s free but you need to register to view it) on Capstone Turbine (CPST) a few days ago. Capstone makes low maintenance microturbines that help in power distribution which can be used in primary or backup power situations. The big Mexican and Brazil oil companies Pemex and Petrobras are its biggest customers but the company’s turbines are used in a wide array of industries and could be used in hybrid vehicle and solar energy applications in the future
