太陽能電動自行車 ?

不論是為了省油錢、健身、還是為了趕上流行時尚，現在全台灣最流行的假日休閒運動大概就是全家人一起去騎腳踏車了。

前幾天，我們全家人也在烈日下沿著河濱公園騎到了士林科博館，雖然不是很長的路程，騎的車子也不是麼名牌車，即使塗了防曬油，後來幾天我的皮膚還是因此曬黑不少。雖然一路顛簸，汗水淋漓，但這趟全家自行車之遊，還真是充滿了樂趣，也讓我領略到了為什麼現在台灣有這麼多人這麼喜歡騎自行車了。

當然，沿途頂著烈日流著大汗，我總是免不了有職業病，腦袋不停地想發明看看有沒有更輕鬆的方式騎車，而且還自以為聰明的想去申請個 "太陽能電動自行車" 的專利而竊竊自喜。

不過回家一查，相關的發明原來已經不少啦，而且還有一位天才老兄，乾脆直接把太陽能電池穿在身上當作電動自行車的電源，也可算是一絕啦 ! 有興趣的朋友，可以上 USPTO 美國專利資料庫查一查 "Solar" + "Bike"，你會發現 67 項相關專利，其中有幾個很有趣的發明，有興趣的朋友趕快去研究研究吧.....
