Tämä taulu oli aikoinaan vertaansa vailla. Maanviljelijä Kai Knaapinen aloitti energiapajukokeet 1992 Pohjan kunnassa sijaitsevalla Nygårdin tilallaan. Hän suivaantui kokeilun saamaan irvailuun, ja teetätti omalla kustannuksellaan kuvan esittämän taulun. Se ihmetytti ohikulkevan maantien kulkijoita noin 10 vuoden ajan.
This table ("Willow is the tree species of our time") was the only one of its kind. Farmer in the municipality of Pohja in south-western Finland, Kai Knaapinen started the energy willow experiments in 1992. He experienced such an amount of resistance that he decided to erect the big board as shown in the picture. The board stayed on its site for about 10 years.
