ミミズは土の中にいても決して泥まみれになっていない。それは、ミミズが土の中を移動する時に自然にミミズの表皮にマイナスの電荷が生じるからである。土の中に小さな粒として含まれる水はプラスの電荷を帯びているので、水はミミズの表皮に引き寄せられる。集まってきた水は、薄い膜のようにミミズの表皮を覆い、バリヤーのように働くので、ミミズの表皮に土が付着することはない。同時に潤滑剤の役割も果たすので、ミミズは土壌中をスムーズに動くことができる。
洗浄の必要がない、トラクターのような農耕用の車両、ブルドーザーやトラックのような工事現場や鉱山での掘削に使われる車両の開発に応用できる。植物の生育のために土壌内の土から水を集める技術の開発に応用できる。乾いて硬く圧縮された土に水を通して土壌を回復させる技術の開発に応用できる。
