Spanish solar tower could eventually power an entire city
Just last month we witnessed a gigantic skyscraper / solar tower hybrid that generates a whopping 390-kilowatts of energy, but even that looks like child's play compared to the 40-story solar power plant that resides in Spain. The expansive system consists of a towering concrete building, a field of 600 (and growing) sun-tracking mirrors that are each 120-square meters in size, and a receiver that converts concentrated solar energy from the heliostats into steam that eventually drives the turbines. Currently, only one field of mirrors is up and running, but even that produces enough power to energize 6,000 homes, and the creators are hoping to see the entire population of Seville (600,000 folks) taken care of solely from sunlight. So if you're eager to see what's likely the greenest solar power plant currently operating, be sure to slip on some shades, tag the read link, and peep the video.[Via Wired]
UK's CIS Solar Tower garners 390-kilowatts from the sun
We're not entirely sure if Manchester's CIS Solar Tower will be the world's grandest solar tower, but in terms of buildings have moved beyond the drawing board, it definitely packs a punch. Reportedly, the flaky construction led to dilapidating walls, which were then replaced by a much greener solution -- 7,244 Sharp 80W photovoltaic panels, to be precise. Curiously, only 4,898 of the modules are actually functional, but they still soak up enough sunlight to generate 390-kilowatts of energy, or in layman's terms, enough juice to "power 1,000 PCs for a year." Additionally, the roof is home to two dozen wind turbines that generate 10-percent of the total power used in the building. Of course, such an endeavor did ring up at a steep £5.675 million ($11.4 million), but we're pretty certain this solar panel makeover was concerned with matters other than dollars and cents.
