What we think about it?
Understanding + Experience
* Feasibility: The quality of being doable

EVALUATION BASED ON TECHNOLOGY READINESS ASSESSMENT
Objective - is to determine the readiness of the technologies that may be used in the design concept. Immature technology will lead to a poor-quality product or cancellation of a project due to cost overruns.
Time-Line for Technology Readiness
Technology Development Time
Powered human flight 403 (1500 – 1903)
Photographic cameras 112 (1727 – 1839)
Radio 35 (1867 – 1902)
Television 12 (1922 – 1934)
Radar 15 (1925 – 1940)
Xerography 17 (1938 – 1955)
Atomic bomb 6 (1939 – 1945)
Transistor 5 (1948 – 1953)
Digital camera 30 1965 - 2004
High temperature super conductor ? 1987 - ?
Electric car 1900 - ?

EVALUATION BASED ON TECHNOLOGY READINESS ASSESSMENT
Six measures to determine if a technology is mature:
1. Can the technology be manufactured with known processes?
2. Are the critical parameters that control the function identified ?
3. Are the safe operating parameters known ?
4. Have the failure modes been identified ?
5. Does hardware exist that demonstrates positive answers to the above four questions ?
6. Is the technology controllable throughout the product's life cycle ?

Displacement on Demand has been in works for the last 25 years…..
finally:
GM announces that the 2005 model year GMC Envoy XL, Envoy XUV and Chevrolet trailblazer EXT will be the first vehicles to showcase its innovative Displacement on Demand fuel-saving technology, which enhances fuel economy without compromising performance or the ability to carry heavy loads. Displacement on Demand is to be a standard feature in the vehicles' optional Vortec 5300 V-8 engine. The technology, which boosts the Vortec engine's fuel efficiency by 8 percent, is also to be introduced in other GM engines in the 2006 model year.
