Mushroom and bacteria turn light into clean energy

The video discusses how a team from the Stevens Institute of Technology used 3D printing to create a pattern of conductive carbon on mushrooms, turning them into renewable energy hosts. Cyanobacteria, known for its high efficiency in converting sunlight to energy, was printed on the mushrooms using bio ink. When exposed to light, the cyanobacteria undergo photosynthesis, releasing electrons that are captured by graphene strips, generating 65 nanoamps of electric energy.

What environmental conditions make mushrooms ideal for bacterial growth?

• High humidity and temperature

• Cold and windy conditions

• Low light and dry air

• High altitude and low pressure

What technology did the team use to create a conductive pattern on mushrooms?

• Laser cutting

• 3D printing

• Nanotechnology

• Chemical etching

Why was cyanobacteria chosen for this experiment?

• It is easy to cultivate

• It has a high internal quantum efficiency

• It is resistant to high temperatures

• It is a rare species

What happens when the mushroom is exposed to light?

• The mushroom absorbs more water

• The mushroom releases spores

• Cyanobacteria initiate photosynthesis

• The mushroom changes color
