In May 2006, Alameda County’s Santa Rita Jail brought on-line an exciting hybrid energy generation system that includes solar arrays, fuel cell stacks, and co-generation; all functioning in tandem. Covered in an Energy and Power Management article entitled “Santa Rita’s Fuel Cell Adds Reliability to Solar Installation”, this hybrid energy system provides grid-beating electrical conversion efficiency (49%), low pollutant emissions, and redundancy against grid failures and brownouts.
The twin centerpieces of the Santa Rita Jail instillation are a 1.2 MW photovoltaic array from PowerLight and a 1 MW Direct Fuel Cell® from Fuel Cell Energy. Being a carbonate fuel cell, this power plant runs hot enough to enable internal reformation; so, natural gas can be used as fuel, instead of hydrogen. Overall, this system saves Alameda County (which is in California) over $266,000 per year in electricity costs alone, not to mention offset heating costs and waived air quality permitting requirements.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
