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.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
Design News and Digi-Key presents: Creating & Testing Your First RTOS Application Using MQX, a crash course that will look at defining a project, selecting a target processor, blocking code, defining tasks, completing code, and debugging.
These are the toys that inspired budding engineers to try out sublime designs, create miniature structures, and experiment with bizarre contraptions using sets that could be torn down and reconstructed over and over.
PowerStream is deploying the microgrid at its headquarters to demonstrate how people can generate and distribute their own energy and make their homes and businesses more sustainable through renewables.
