10^F推rookiebear:我覺得很棒呀!!我也曾想過如果在山上墜崖是否有方法逃03/13 20:25

11^F→rookiebear:最後跟你得出差不多的結論~用氣球!!但...有幾個問題03/13 20:26

12^F推rookiebear:氣球要相當大顆才可能將人載上去,隨身攜帶或許不行03/13 20:31

13^F→rookiebear:但若是固定在某處的ex:自宅用,那大顆氣球的存放和氫氣03/13 20:32

14^F→rookiebear:供給就都一併解決了!!飄浮時用繩索固定在屋子附近就不03/13 20:34

15^F→rookiebear:會飛走,如果再附個氫電池,等安全落地後,或許還可以發電03/13 20:37

16^F→rookiebear:先救急一下03/13 20:37

6^F推rookiebear:這值得討論...以前就有把這作為科展的題目02/28 18:47

7^F→rookiebear:他是用單車的煞車系統作為研究主體02/28 18:50

[問題] 下雨天騎機車穿雨衣很麻煩，有啥好方式改善呀?

1^F推rookiebear:我想,人類以獸力為交通工具後,就一直在困擾這問題了= =02/21 18:27

2^F→rookiebear:除了結構本身就是全罩的交通工具外...似乎沒有好方法..02/21 18:28

3^F→rookiebear:個人淺見...02/21 18:29

1^F推rookiebear:的確有這種設計啊不過這大部分是利用自然現象所以會01/09 09:32

2^F→rookiebear:跟風力發電一樣來源定是有利用儲存不同氣壓時的空氣01/09 09:34

3^F推rookiebear:藉其氣壓差來電的不過電量也不大01/09 09:47

4^F→rookiebear: ^發第二行是"來源不穩定"01/09 20:08

22^F推rookiebear:樓上廣告01/12 22:36
