This is not one of those parabolic cigarette lighters, or even a magnifying glass, this device’s sole function is to make sparks so you can ignite your gas stove or your furnace. This device contains no fuel, its only job is to make sparks, that’s it. Meaning it is pretty useless. However, it is pretty.

from the (translated from German) website.

Here it is the new electrónico lighter fed the solar energy! The solar cells of that it makes use recharge the stack of lithium in its interior, using one any source of light, solar or artificial. This system of very simple feeding, allows it to produce a continuous series of sparks of high potential that will decide any problems of firing of all the types of gas. E
it is not alone! The support base can be used to open capsules and to unscrew bottle covers. Of material anti-shock and metal. Dim.: 25 cm comp. Assorted colors.

So maybe I lied, it does have one more job, opening capsules and to unscrew bottle covers. So you can pop open your beer, then make sparks. I guess if you had a nice pile of tinder and some time on your hands this would be a very nice survival tool (if you kept it dry). Who knows maybe this will be the flint and steal of the future?
