Soil Lamp Runs on Mud

soil lamp
The Soil Lamp by Marieke Staps runs on mud. The lamp has copper and zinc strips coming out from the bottom of it and uses the soil as an electrolyte to power the LED light (just like a potato battery you created in grade school). The soil does need occasional waterings to keep it muddy so the reactions can continue to light the lamp up but beyond that, it should be maintenance free. This is the type of light that would be perfect for lighting up a shady path or garden area- just stick it in the soil and that’s it. Oddly, it doesn’t appear to have an on/off switch.

  1. One day, the truth shall “Out” and the corporations will bow heads in shame! and men will have almost free light for evening prayers. as no more night shifts for “The Man” will be worked, and the profit motive scrapped for the tranquil life ideals. A new low current, high current charge/discharge battery has been discovered. peak wind power can be absorbed for lower level discharge in our service later, Low current “ground currents can be collected at very low levels, to be discharged, even in battery cars or for electronic equipment, later, as we wish!
    LED lights SEE:
    “A £2 energy-saving lightbulb that lasts for 60 years has been developed by scientists at Cambridge University. The researchers have designed a bulb that is three times more energy efficient than today’s best offer and can cut lighting bills by 75 per cent.The bulbs are 12 times more efficient that conventional tungsten bulbs and three times more efficient than compact fluorescent “energy efficient” bulbs. They can burn for 100,000 hours and they illuminate instantly and can be dimmed, unlike energy efficient bulbs.”

    If we can adapt to the small differences, we are for all practical means, approaching the end of dependence on Oil and Nuclear power! and cancers for the bigger part! Hooray!
