Small Biomass Icon

Biomass and other 60,600 icons from Icons8 icon pack follow the visual guidelines of the operating systems: Windows, iOS, Android KitKat, and Material. PNG format is free up to 100x100 px.
It looks like a little flower inside of a science beaker. The flower is simply the bulb without the stem and its resting near the bottom center of beaker.

Idea of Biomass Icon by Eric Brissette

We've received the idea on January 29, 2013 and created the icons on April 04, 2013

Icons for green/renewable energy sources. The two I'm looking for are a Wind Turbine and Solar Panels. Other possible ideas are Hydroelectric, Geothermal, and Biomass, but those icons may be more difficult to portray with a simple icon.
