Inventions that generate electricity from plants or fire

Getting a charging point for a mobile device or a small appliance is possible from quite atypical renewable energy sources. We are not talking about solar, wind, or even geothermal energy or that from conventional biomass , but about obtaining electricity from fire or from the photosynthesis of plants.

Back to the fire

Extracting electricity from fire is another initiative that is on fire. It is intended to use natural resources, as the human being did at the dawn of humanity, but giving it a twist with new bioenergetic technologies .

The Biolite kitchen is an example of this desire to take advantage of this universal raw material. It is a new model of stove specially designed for campsites or gardens that allows you to transform fire into electricity, more than enough to charge your GPS , phone and tablets, all at the same time. After exceeding its goal on Kickstarter, it will go live soon.

A somewhat more modest but specific alternative for this use is FlameStower, which allows three minutes of calls for every minute of recharging in the terminal, being able to charge other mobile devices as well. It’s another invention that has been hugely successful on Kickstarter.

Taking advantage of photosynthesis and the calorific power of fire for this use offers advantages in two ways, since they can be used continuously and are easily regenerated, although they are not strictly an inexhaustible source in the style of those.

There are numerous experiments and first prototypes that try to do it, achieving greater or lesser success. Some are based on conceptual works that show the potential of technology. This is the case of the moss-covered table with built-in lamp, an example of what the Biophotovoltaics project aims to achieve.

In reality, neither the lamp lights nor produces enough electricity to charge practically anything. Yet. In the future it is expected to be able to power telephones, computers … although today it is an interesting conceptual product, yes, loaded with virality , which seeks to draw attention to the possibilities of exploiting photosynthesis in living organisms , such as cyanobacterial plants, mosses or algae.

Swiss designer Fabienne Felder has been working in collaboration with the University of Cambridge for the first radio of the world fueled by plants . The idea is simple: photosynthesis is converted into electricity even when there is no light, and while there is still a long way to go, it is expected to be commercialized within a few years.

But why is photosynthesis a source of energy? As is known, photosynthesis is a process by which plants convert carbon dioxide into organic compounds. They achieve this, among other things, thanks to solar energy and their objective is to use them as food to grow.


In this way, when the plant releases some of these organic compounds into the soil, which contains bacteria , they also decompose these compounds for their subsistence, releasing by-products that include electrons. Logically, these electrons are the target of these technologies, so they are captured using conductive fibers , accumulating in batteries to be used.
