Pulse detonation engines (PDE) can achieve a maximum of 50% efficiency verus 30% for conventional jet engines Pratt & Whitney and General Electric now have active PDE research programs in an attempt to commercialize the designs with high pulse rates of 50-100 times per second to allow for less vibration. Some of the top scientists …
Accelerating future had reviewed systems for getting into space in 2006 I had covered the EM drive but is definitely one of the long shots with a lot of unknowns in the science (ie. I seriously doubt that it will work). My preferences are for: Bussard IEC fusion earth to orbit spaceship. Credit: Tom Ligon …
More than two-thirds of all the oil discovered in America to date remains in the ground and is economically unrecoverable with current technology. About 218 billion barrels of it, a volume approaching the proven reserves of Saudi Arabia, lies at depths of less than 5,000 feet. This by-passed oil represents a huge target for the …
Worldwatch indicates that China will likely achieve—and may even exceed—its target to obtain 15 percent of its energy from renewables by 2020. If China’s commitment to diversifying its energy supply and becoming a global leader in renewables manufacturing persists, renewable energy could provide over 30 percent of the nation’s energy by 2050. China’s carbon dioxide …
