Preliminary Design of a Laboratory Cylindrical Hall-Effect Thruster

, 2012
A 3-cm cylindrical Hall thruster with permanent magnets was designed and modeled. The goal was to design a Hall thruster for Cal Poly’s propulsion laboratory of similar size and performance as Cal Poly’s MiXI thruster.

Beyond Compliance: The Role of Climate Policy Stringency and Financial Institutions in Cleantech Startup Entry

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how environmental regulations can drive technological change, drawing on the innovation systems perspective and the strong Porter hypothesis (SPH). The SPH suggests that well‐designed stringent regulations can foster innovation and enhance firm competitiveness, performance, and survival, yet prior research remains largely ...
