De tror på rumvæsner
Mennesker,
der tror på ufoer og besøgende rumvæsner, må ikke afvises som tosser.
For hvad nu, hvis det bare er mennesker, der prøver at få deres verden
til at give mening?

Nasa's "teaser" announcement sparked a frenzy of excitement in the
Twittersphere with space enthusiasts trying to guess what might have
been found.
Many picked up on the excitement and speculated that we were about to hear about an alien discovery.
Instead of plugging a lamp into a wall socket or flipping the switch
of your overhead light, try illuminating your room with a potato.
Yes - you read that correctly. With one scientific process, a simple
potato can light up an LED bulb for an entire month if it's done
correctly.
Haim Rabinovitch, a professor of science and agriculture, attached a
classic copper cathode and zinc anode together with a metal wire
conductor and let the potato "cook" for eight minutes. That's when he
discovered the charged potato could produce a harnessable form
of electricity.
This charge not only ran through the potato, but it had the
capability to illuminate an LED lightbulb bright enough to light a room
for over 40 days!
The specific compilation of elements with the potato is great for
scientific discovery and progress, but it's also helpful for third-world
countries that don't have the power, money or resources to use
electricity and modern-day light bulbs. However, if provided with
electronically charged potatoes (and it's made clear that they're not
for eating), these rural areas could be brightened without spending
millions in infrastructure overhauls.
There's an endless number of possibilities for these light-bearing vegetables, and Professor Haim is just getting started!
