Battery–Free Perpetual Flashlight

What's this?

They've mastered cold fusion and used it to power a... flashlight?

No — not quite.

But be patient.

In the meantime there's this quite arresting looking "shake–'n–bake" flashlight for your inspection.

From the website:

This remarkable EverLife Flashlight never needs batteries or bulbs so it's maintenance-free.

It uses your energy and electromagnetism to produce a bright blue/white light using super-efficient LED technology.

Just shake the light for about 30 seconds and the EverLife Flashlight provides up to 3 minutes of light.

Shake it for 10-15 seconds every 2 or 3 minutes for an unlimited supply of light.

Perfect for emergency kits — you can leave it in your car, home, boat or RV for months at a time and it still gives you light when you need it.

The bright LED will last for thousands of hours and may never need replacing.

Features a waterproof, floating plastic body.

LED can be seen a mile away.

How does it work?

When the flashlight is shaken back and forth a strong magnet passes repeatedly through the visible copper wire coil and charges the capacitor.

Where were you when they covered electromagnetism during high school physics?

Passing notes?

IM'ing your friends?

Whatever.

They've sweetened the deal.

You get not one but two flashlights: the regular 8"–long version and a mini iteration, 5"–long and perfect for your pocketbook or bag.

$19.98 here (batteries not included).

Shake it up.
