The picture on the left is a lamp lit by gravity.  It is named “Gravia”.

This floor lamp was created by Clay Moulton, a Virginia Tech student.  The concept of Gravia is to move the weight in the lamp to allow the heavier weight goes on top, and let the weight slides down slowly.  This activate the lamp as the sliding mass spins a rotor, and the LEDs glows.  Other features of this lamp?  It is noise-free.  In other words, it works silently.  This device is also a really long-life one.  You can pass it to your children, grandchildren or even great grandchildren.  It is said that the mechanisms of Gravia can last more than 200 years (eight hours a day, 365 days a year).

Comparing to the switch, some lazy people might thinks that it’s very troublesome to move the lamp every certain period just to let it glow.  We can work on that, for example, making a device that turn the lamp after a certain time.
