Free Electricity from Compost – DIY Earth Battery.

Free Electricity from Compost – DIY Earth Battery.

The lab called ‘Earth’ has been researching & perfecting how to harvest solar power for over 3 billion years.  The best way was found to be:  bacteria & plants.

A teaspoon of soil can contain upwards of 50 billion microbes (for comparison, there are about 7.3 billion humans on our entire planet).

So, where do we find bacteria?

COMPOST…GARDEN SOIL…POTTED PLANTS…WORMFARMS…GREYWATER SYSTEMS…BLACKWATER SYSTEMS…AQUATIC PLANTS…so many places!

HOW IT WORKS…dead organic matter is decomposed by bacteria via redox processes (RED = reduction & OX = oxidation).  The organic substrate is oxidized (looses electrons) & another molecule (i.e. oxygen in aerobic environments) is reduced (gains electrons).  Bacteria use the energy gained from these electron transfers, along with some carbon from the organic matter to produce more cells.  However, bacteria can reduce other molecules too – so the process can occur in many different environments (even those without oxygen or with extreme acidity, temperature etc).

In addition to the metabolic electrochemistry of bacteria, many other natural processes generate electricity in the ionosphere around planet Earth, within the mantle, in aquatic environments & the atmosphere.  Together, they combine to create telluric currents & electricity within soil.

Organic matter is decomposed by bacteria to produce new cells. During the process, electrons are released. [3]

HOW ELECTRICITY IS GENERATED…

  1. A zinc screw* acts as the negative anode to attract electrons generated by bacteria in the rhizosphere (root zone) &/or telluric currents.
  2. Electrons flow through the circuit to produce electricity.
  3. Copper wire* acts as the positive cathode & releases electrons back to the soil.

*other metals can be used for the anode & cathode.

[4]

To boost output…

…add more cathodes/anodes to create a series & join together as a single circuit. This will boost output by the number of electrodes added.

[6]

…add worms to increase organic matter & charged particles. This will boost output by 800% or more!

…organic fertilizers – mulch, manure, seaweed & other organic matter which has entered the degradation process. This will boost output by 45% or more!

…molasses & other soil tinctures – to feed the soil bacteria & increase their numbers. This will boost output by 38% or more!

OUTCOMES:

  • Sustainable electricity generation.
  • Power monitoring equipment (ie. nutrient loading in blackwater system).
  • Power lighting (ie. driveway, attract insects over water to feed fish etc.)
  • Rapid recycling of used water (greywater & blackwater systems).
  • Degradation of pollutants (including phenol, petrol & oil).
  • Rapid growth of bacteria (conditions soil, compost booster).
  • Mitigation of methane (a strong greenhouse gas).
  • Mitigation of carbon dioxide (a greenhouse gas).
  • Production of water.
  • Evolution of oxygen.
  • Development of green technology & innovations.
  • Meet your needs!

Battery talk – using bacteria to GROW batteries…

[7]

     Ancient organisms have evolved to make exquisite nanostructures like shells and glassy diatoms.  Using directed evolution, the lab engineers organisms to grow and assemble novel hybrid organic-inorganic electronic, magnetic, and catalytic materials.  In doing so, the group capitalizes on many of the wonderful properties of biology – using only non-toxic materials, employing self-repair mechanisms, self-assembling precisely and over longer ranges, adapting & evolving to become better over time.  These materials have been used in applications as varied as solar cells, batteries, medical diagnostics and basic single molecule interactions related to disease.
