On April 4, 2016, this article was published in The Space Review. (A PDF version of the article is here.) The United States is transitioning from a primary reliance on fossil fuels to greater use of sustainable natural and nuclear energy sources. There are two reasons for this transition. The Continue reading 60 – Space Review article: Federal Legislation to Jumpstart Space Solar Power

When I first started this Spacefaring America blog in 2007, the conjunction of “space” and “faring” into “spacefaring” had not yet entered common usage. While humans had been seafaring for tens of thousands of years, the notion of extending this three-dimensionally into the endless frontier of outer space had not Continue reading 61 – The hyphen is not yet quite out of “space-faring”, but it should be

While American astronauts made history in turning President Kennedy’s manned lunar landing challenge into reality, behind the scenes were remarkable engineers that turned technologies into operating capability. Hubert P. (Hu) Davis was one of the leading engineers that made this possible. His contributions were especially important for the Apollo 11 Continue reading 59 – In memory of an outstanding Apollo 11 engineer – Hubert P. Davis

58 – Space Review series (Part 3): US Terrestrial Non-Fossil Fuel Energy vs. Space Solar Power

An 82-acre tract in south central Colorado, near the New Mexico border, is the site for one of the largest photovoltaic power plants in the United States. The Alamosa Photovoltaic Plant, which went on-line in December 2007, and generates about 8.2 megawatts of power using Suntech solar modules.  SunEdison built, owns and will maintain the Alamosa plant and Xcel Energy will purchase the power generated by the plant.  NREL rates the San Luis Valley, where the plant is located, as having the best available resource for solar power conditions in Colorado.
