he Solar Bottle Lamp is a solar-powered light
that reuses a waste plastic bottle by attaching
a 3D-printed solar lamp in place of the old
plastic cap. It also makes clever use of the
light-refracting properties of water!
I designed this lamp as a low-cost solution for
lighting rural homes, replacing their harmful
kerosene lamps and at the same time upcycling
some of the millions of waste plastic bottles
that are daily thrown into the garbage. These
lamps are also great for decorating a garden, for
camping or traveling, or for emergencies when
the power is out.
