Push-button fungus covered with insects and nanoparticles can produce electricity from light

American scientists have successfully tested a somewhat magnificent idea of ​​producing electricity from bacteria-covered fungi.

Researchers have used 3D printing to attach piles of energetically significant bugs to the shutter.

This fungus provided the ideal environment to allow cyanobacteria to generate a small amount of energy.

The authors claim that their fossil "bionic mushrooms" can have great potential.

  • Which green energy is the cheapest?
  • Large water reservoirs are not "sustainable"

As researchers in the world have been looking for alternative sources of energy, there is a sharp increase in interest in cyanobacteria.

These organisms, which are commonly found in the oceans and on the ground, are examined for their ability to convert the sunlight into an electric current.

One of the big problems is that they will not survive on the artificial surface long enough to deliver their potential.

This is where the tomb with the humble button appears.

Cyanobacteria have great potential when converting light into energy

This fruitful fungus is already home to many other forms of bacterial life, providing an attractive range of nutrients, moisture and temperature.

So scientists at the Stevens Institute of Technology in the US have developed a clever method of marrying sparrows.

They reasonably came up with an idea at lunch!

"One day we and our friends went to lunch together and ordered some mushrooms," said Sudeep Joshi, a postdoctoral researcher and author of the study.

"When we discussed them, we realized they had their own rich microflora, so we thought why not use mushrooms to support cynobacteria. We thought we'd connect them and see what was going to happen."

Using a special bio-ink, the team of bacteria printed the honeycomb cap in a spiral pattern. Previously, they used electronic ink to insert graphite nano-belts onto the surface of the sponge to collect the current.

When the light sparkled on this magical sponge, they caused cyanobacteria to generate a small amount of electrical energy.

It is not a complete moment, but the proof that this idea works. Scientists say that several sponges connected together could ignite a small lamp.

"We are trying to combine all the mushrooms in a series, in a row, and we also try to pack other bacteria together," said Sudeep Joshi.

"These are the next steps, optimizing bioprocesses, generating more electricity, feeding small LEDs."

A great benefit for the experiment was the fact that bugs on the mushrooms lasted several days longer than cyanobacteria placed on other surfaces.

Scientists believe that this idea could have potential as a renewable energy source.

"Right now we are using the cyanobacteria pond, but you can genetically engineer them, and you can change their molecules to produce higher photographic currents through photosynthesis," said Sudeep Joshi.

"It is a new beginning, we call it a technical symbiosis. If we are to carry out further research in this research, we can actually move this area forward to have some kind of green green technology."

Jump from fossil fuels to mushroom fuel need not be so far.

The study was published in Nano Letters.
