Moser Lamp: a plastic bottle makes free light

_69142255_img_8451With electricity becoming more expensive, here’s a way to save resources and get free lighting.  The Moser Lamp, invented by Alfredo Moser, is simply a clean empty plastic bottle filled with water and a little bleach.  Using the natural science of refraction, the lamp puts out the energy of a 40-60 watt bulb depending on how strong the sun is.  In areas where power outages are common and in areas of poverty, Moser Lamps are becoming a great way to provide light to homes cheaply and efficiently.

How much energy do Moser Lamps save?  Since plastic bottles are recycled/up-cycled from local communities, there’s no energy needed to gather, manufacture, or ship new bottles, whereas it takes 0.45 kg of CO2 to manufacture one incandescent bulb.  Plus, a 50-watt light bulb running for 14 yours a day for a year has a carbon footprint of nearly 200kg of CO2…whereas Moser lamps emit no CO2 at all!    Even in first world countries, this would be a fun idea for playhouses, garden sheds, pump houses, etc.
