Respected Reed and jason Complicated life and chemistry , need system thinking to understand using simple componenst system, this need more time , as one do not find time, stop thinking, thus making life more hard to live.System thinking can help to get Knowledge, Ability , Competence to understand the complications , find which can be the correct innovative answer. to complex problems .This really need preservance ,freedom to innovate and flexible thinking withou the fear of money , time and materials.In this list we have many system thinkers , pyrolysis, gasification , reforming , biomass, gasifiers etc.
