Bioluminescence, which means "living light," occurs in fireflies , certain fungi and fish, and microorganisms like dinoflagellates, a species of algae .  Dinoflagellates in marine environments can multiply rapidly with the right combination of sunlight and nutrients, and when the water around them is agitated their distinctive blue or green glow becomes visible. Since a natural dinoflagellate "bloom" occurs only rarely, try growing them at home to experience the beauty of bioluminescence. Gather a few materials, set up the appropriate light and temperature conditions, and wait for nighttime to watch the algae sparkle and glow. <p style="text-align:right;color:#A8A8A8"></p>
The principle is simple and seductively clever: solar lights that store energy during the day and release light at night. These can be purchased ready-made in a variety of colors (yellow, blue and red) but they can also be built at home . A simple, less-technical approach involves buying a conventional solar-powered yard lamp and then essentially harvesting it for key pieces to put in a jar. This is simply a way of taking an existing solar lamp design and appropriating its parts to make something more attractive for display around a house or home.

Annual Output (KWH/year) = 0.01328 (D^2) (V^3) source... Where D^2 is the blade diameter in feet squared, and V^3 is the wind velocity cubed in mph -- this is the year round average wind speed -- see wind maps below. So, a 10 ft diameter wind turbine in 12 mph average winds might produce about (0.01328)(10^2)(12^3) = 2300 KWH/year Note that the energy produced is proportional to the cube of wind speed -- having enough average wind speed is everything in wind turbines. Use the wind maps discussed below and a wind survey of your site to determine if a wind turbine will actually payoff. The graph is of the wind energy equation shown above for various wind speeds and turbine blade diameters
