This is an assessment of current two-stroke automotive engine technology, implementation policy, vision, goals, and engine development and commercialization strategy. It includes a historical review of key two-stroke Otto cycle engine developments, a summary of the specifications for the new: Suburu Super 2-stroke, Toyota S-2 gasoline engine, Orbital two-stroke, General Motors GMCDS2 two-stroke engine and Industrial Technology Research Institute (ITRI) two-stroke engine test technology in Taiwan. Although two-stroke engine technology has been under development since the end of the 19th century, currently the only mass produced vehicles powered by two-stroke cycle engines are the Trabant and Wartburg, with 594 cc two cylinder and 993 cc three cylinder engines, respectively, essentially unchanged in cylinder configuration and porting since 1931.

This is an assessment of United States High Speed Guided Transit (HSGT) systems policy, vision, goals, and magnetic levitation development and commercialization technology; as affected by the new United States National Energy Strategy. It includes a brief review of the key aspects and assumptions which formed the basis for the US National Energy Strategy scenario, and the tactics proposed to implement a National Maglev transit network by the target year 2015 (1)1. It is followed by a historical review of past magnetic levitation vehicle developments, a review of the present status of Maglev trains, and an outline of future (EMA) Electro Magnetic Attraction levitation for speeds under 400 km/h; (SC) Super Conductive (EDR) Electro Dynamic Repulsion levitation for subsonic speeds approaching 900 km/h; and, an introduction to the (MPW) Magnetic Potential Well levitation effect as developed by Kozoriz (2) in 1976, also see (39).
