After reviewing different ideas on how to make them work for a years without service and any external power supply, Soviet engineers decided to implement atomic energy to power up those structures.

So, special lightweight small atomic reactors were produced in limited series to be delivered to the Polar Circle lands and to be installed on the lighthouses.

Six of the groups have their own name – perhaps the most well-known of these being the noble gases (group 18).

Here are five facts you might not know about it (despite all those hours spent in science class) and Mendeleev himself: On 4 January, it was confirmed that elements 113, 115, 117 and 118 would be added to the table’s seventh row to make it complete after they were verified by the International Union of Pure and Applied Chemistry on 30 December.

So it has been done and a series of such lighthouses has been erected.

The inventor formulated the periodic law – which states that elements can be arranged by their mass and be organised into groups that share similar chemical and physical properties.Also here is the spectacular Kurhaus, Baden-Baden's oldest and best-known resort establishment, built between 1821-24 in the style of a French chateau.The pleasant gardens in Kurpark are also worth a visit and include interesting buildings such as the Trinkhalle or Pump Room and the Greek-Romanian Chapel built in 1863-66 with its interesting tombs.Those small reactors could work in the independent mode for years and didn't require any human interference, so it was very handy in the situation like this.It was a kind of robot-lighthouse which counted itself the time of the year and the length of the daylight, turned on its lights when it was needed and sent radio signals to near by ships to warn them on their journey.
