Ever walk through Times Square and wonder how much electricity all those flashy billboards are soaking up? No? Well, Ricoh has, and now they're doing something about it. Ricoh Company Ltd. of Tokyo is erecting a 47 x 126-foot billboard at Seventh Avenue and 42nd Street that will be completely powered by the sun and wind. Fueled by 45 solar panels and four wind turbines, the billboard won't even need a backup electric generator. On days that the sun and wind aren't enough to power it, it will simply go dark. In the end, the billboard is said to reduce carbon dioxide usage by 18 tons a year. The billboard will go live in December, or just in time for the sun to go dark.

Unlike Rock Port, Missouri, the entire state of Delaware won't be 100-percent wind-powered after Bluewater Wind constructs a $1.6 billion wind park just off its shore, but the state will be able to "light about 50,000 homes a year" for the duration of the 25-year contract. Said agreement was just nailed down between the aforesaid firm and Delmarva Power, and it hopes to start powering homes via wind by 2012. The offshore site will sit around 12 miles off Rehoboth Beach, with a number of turbines to be planted 90-feet into the sea floor and sport three blades apiece measuring 150-feet long. It's noted that vacationers and locals alike won't be able to notice the park from the beach except on a few remarkably clear days, but if their energy bills sink because of it, we don't really think they'll mind, anyway.

As wind energy becomes a practical necessity, designers are scrambling to make the giant spinny things as visually inoffensive as possible. Some are small, some are off in the sea where we can't be bothered, and some just look really pretty. In this case, Broadstar AeroCam developed this handsome horizontal-axis turbine that can be installed in any number of configurations and shipped easier than other turbines, making it a viable solution for those who don't want to erect a giant pole or get involved in construction. AeroCams work on the physics of air lift -- like wings on a plane -- resulting in a huge amount of power from a small package given the amount of blades per unit. Broadstar also brags that the system's price is a boon as well -- a 250kW system runs $250,000, which it says makes AeroCam the first wind power system to break the $1/watt cost barrier.

It's not just the fitness club types in Hong Kong attempting to generate a bit of renewable energy, inventor Lucien Gambarota -- the very man responsible for converting all that cardio into voltage -- is showing off some micro-wind turbines for even more power bill relief. There's currently only a single wind turbine on a small outer island providing energy to Hong Kong, the rest of the city just doesn't get enough wind for traditional turbines to do any good. Not so with Gambarota's new micro-turbines, which can generate electricity with as little as 2 mph of wind, and keep turning at all times from the slightest of breezes. The little windmills are actually gearwheels, mounted in a array. They can be arranged in different shapes and sizes, from two to thousands of square meters. The energy is put into a battery, which then powers appliances in the building. Currently the micro-turbines go for about $25 for a set of 20 gearwheels, but that price should drop considerably once they begin to be mass produced.
