我簡單的說
如果熱力學第二定律就把你限制住了
那你根本沒有機會跳出這個框架
根本不會去想~根本不會去看~根本不會去思考
大師講的話就是"完全正確"不需要去質疑
世界上如果有一定就好了呢...
※ 引述《mechtec (小豆)》之銘言:
: 我之前曾幫國科會審過很多一般民眾自認為發明了永動機的提案
: (甚至有一個老伯伯開宗明義就說:你們這些科學家都是笨蛋)
: 事實上,無論這個東西能不能動
: 只要能量轉移(無論何種形式),就一定會有能量損失
: 這是熱力學第二定律的基本概念
: 到目前為止,人類還找不到任何CASE能將其推翻(所以這叫『定律』)
: 所以以這個PROPOSAL,先不說這樣接能不能動,完全沒有考慮能量的損失
: 實際狀況是就算轉動比例因齒輪組放大,但轉動能量會因為損失而減小
: 使得整個系統在輪組的轉動愈來愈慢,若無外力,則整個輪組最後會靜止
: 不可能達成永動
