      2006년에 개발되었다는군용

      http://cyclocopter.snu.ac.kr/

      로우터 축에 캠을 장착해서 상 하에따라 양력이 반대로 생기도록 유도하는 것은 아닐까요?<br />개인적인 생각입니다.

      외국에선 교수 혼자서 만드는걸<br />서울대는 교수랑 학생 수십명이 달려들어서 만들었나 봅니다.<br />맨뒤에 제작팀 명단이 꼭 출석부같이 많네요.ㅎㅎ<br />(자존심 상한다;;)

      배터리가 보이질 않으네요...

      <p>대박 빨래 건조기 입니다  <img border=0 align=absMiddle src="http://www.sunjang.com/alditor/emoticons/358.gif" /></p><p>옥상에 있는 수천개의 빨래를 몇시간 내로 ㅎㅎㅎ  <img border=0 align=absMiddle src="http://www.sunjang.com/alditor/emoticons/225.gif" /></p>

      [!--9869|1--] <p>이건 서울대 교수님이 훌륭하신 거 같습니다  </p><p>출처를 밝히는 것은 기본이니까요,,,,</p><p>미국 교수들도 정교수가 되기 전 까지는 (시간/전임/조교수/부교수) 신분도 불안정하고, 월급이 적은 분들이 많아서,  돈 대신에</p><p>상당 수의 분들이 명예에 대한 욕심이 보통 구린게 아닙니다  <img border=0 align=absMiddle src="http://www.sunjang.com/alditor/emoticons/482.gif" /></p>

      비효율적으로 보이지만... 개발하면 더좋은 발명을 할것 같네요^^
