Well, it is being tested now with very good results. The process requires placing electrodes near the roots of plants to capture the energy released in the process of photosynthesis.
And, so far… it does not seem to affect the plant growth at all. This appears to be just waste energy thrown off by the plant in the growth process. Energy that can be captured.
And they have created a “Green electricity roof”. Currently it creates enough energy to power a small device, but the plan is to have a roof that creates enough energy to power half the household. Green, renewable and works day and night, summer or winter.
Curious? Here is more and there is a video at the end.
“Do you want to use your green roof to power your house? Would you like to see each wetland and rice paddy field in the world turned into a power plant without harvesting the plants?“
Their (Plant-e) concept is simple yet incredible, and this is how it works:
When a plant creates food using photosynthesis, a large portion of the organic matter generated is actually excreted by the roots into the soil.
That same organic matter then gets consumed by microorganisms living in the soil, which release electrons as a byproduct of this consumption.
By placing an electrode near the roots, it then becomes easy to harvest this waste energy and turn it into electricity.
In addition, the plants are left unharmed during the entire process. In fact, tests show that the plants will continue to grow normally in the presence of electrodes, providing a constant source of power day and night. Combined with lamps powered by salt water, off-grid locations may have access to sustainable energy sooner than predicted, and areas unsuitable for growing crops could be repurposed as a power source!
There is a modular square-foot garden available now on their website. This can be used to grow herbs and vegetables and start harvesting power.
They even have a DIY kit that is perfect for schools (and home school) applications and even workshops.
According to their website, they are currently looking for people to help them with their testing.
