HONOLULU (HawaiiNewsNow) - A bladeless wind turbine that will not harm birds was among the 95 projects on display at the annual St. Andrew's Priory Science Fair Thursday.

Grades 6 to 12 participated. The winners will go on to the district fair on Feb. 7.

The bladeless turbine is an original design by seniors Sara Middendorf and Shawnalyn Sunagawa. They will soon test it in the field, and if successful, marketing is possible.

"Last year we created a blade turbine and judges expressed the concern that as animals passed by they might be hit by the blades, " said Sunagawa. "This bladeless turbine takes advantage of air properties and allows animals to be deflected away from the spinning parts of the system."

Also displaying today was 2010 state science fair champion Connie Liu. Liu, a senior, invented nine new geometric formulas last year. This year she has discovered three new triangle centers.

Lindsey Fujimoto and Sarah Tamashiro are bent on finding a cheaper way to feed the world – animals and humans. Last year they showed how a waste product from rum-making could be grown into an edible fungus. This year their project shows how the waste product of a biofuel created from the Hawaiian plant banagrass can also be turned into an edible fungus.

Other projects spanned a wide range of themes, some of them rather curious:

"What is the effect of clams in colored water?"

"What color food do birds prefer?"

"Is catnip a repellent?"

"The effect of various candle scents on a person's typing speed"

"The effect of age and blood pressure on middle school students"

"Which fruit makes the best battery?"
