「大人の科学」,蒸氣引擎

The Steam Engine Toy from the Otona no Kagaku.
I thought this steam engine is too heavy to move, besides that, it wastes too much capability by the way it transits power. Surprisingly, This toy can actually drive by the power of the steam enginem about a miter on the wooden surface.

組裝時,本以為引擎的重量太重,且傳動的機制看起來會浪費掉許多的動能,僅是利用傳動軸及橡皮筋將蒸氣所產生的動能傳到輪子,因此這蒸氣車可能根本動不了 (前輪下方有個腳可以將前輪撐起來,讓輪子空轉)
然而在點燃酒精燈後,還真的會噗嗤噗嗤地邊跑邊冒著蒸汽呢

"It's Alive!!"


Camera: Sony T1, Explosure: 1/20s@f/3.5 with slower shutter speed flash

在摩擦力較小的表面上,如玻璃,蒸氣車可以移動相當長的距離;木頭表面的話,如果儲存足夠的動能,蒸氣車可以移動大約1m左右的距離


下一期「大人の科学」內容:機械鐘 tongue.gif 呵呵!

dear KIKILY裏,
《大人の科学》可以在台北紀伊國書屋買到
不過,蒸氣引擎算是過期雜誌了,我問過紀伊國,已經沒有存貨
因此可能需要到日本買了!
這一期的內容是機械鐘,當然我也買了 如果你有興趣的話,就到紀伊國吧

拍賣網站上也曾看到有人賣
或許我也該仿效,我最愛買奇怪有趣的書了
