Abstract
Description
1.回転方向の抗力を受けやすい構造によって起動時における始動の確実性を高めるとともに、風力および太陽光をエネルギー源とする発電量を増加することができる。
2.前縁気流貯留部42に風を集中させるとともに、風向きに対して投影面積を減らすことで抵抗を減らし、回転しやすくすることができる。
3.受風パドルの内面412に生じる揚力により、回転を後押しする力とすることができる。
4.受風パドル4を大型化することにより、揚力とともに発電量を増やすことができる。
5.垂直回転軸2が回転しても、接点にギヤを用いることにより、コード等が回転してねじ切れることがない。
6.受風パドル4の外面411が外側を向くように支持するため、受風パドル4の長手方向を放射方向に沿って配置する場合と比較して省スペース化され、オフィスビルの屋上や建物の傍の空きスペース等にも手軽に設置することができる。
7.軽量な部材で構成することができ、自重による回転抵抗を低減することができる。
