Summer is soon approaching, as does the occasional blackout when local power grids can't keep up with power-sucking air conditioners. And the next time your home loses electricity, you can at least stay entertained by reading—even in the dark—with this lovely lamp that runs completely off the grid.

While most cordless lamps rely on rechargeable batteries, or solar cells, to compensate for their lack of a permanent tether to an outlet, the First Light uses a series of gears, cogs, and weights to keep its LED bulbs (we're assuming) running day or night. Even if your power's out. Like a grandfather clock you will occasionally need to wind the lamp, which raises the weights infusing it with potential energy that's converted to electricity over time. But that's a small price to pay if it means never tripping over an errant power cord ever again. [Post Fossil via The Fancy]

No, it's powered by nuclear fusion in the sun. Plants absorb sunlight, using the energy to separate hydrogen from water and combine it with carbon from CO2 to make glucose through photosynthesis. Then you eat the plants or you eat animals that ate the plants. Then your body metabolizes the glucose to produce energy which powers your muscles when you lift the weight. It's a solar lamp, just three or four times removed.
