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.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
