百幕達之謎
百幕達之謎（一分鐘知識）
有魔鬼三角區之稱的百慕達海域不知吞沒了多少船隻，航行者提起這個地方就發毛，因為十多年己有一百多架飛機，兩百多艘船在此地失蹤，奇怪的是殘骸始終找不到，有時連派去溲索的飛機和船隻也一去不回，所以此地也叫死亡之域或死亡三角區。
死亡三角區是如何埋葬船和飛機呢﹖過去一直是不解之謎，近來科學家努力討究，似乎己找到線索。 原來百幕達三角區海域潮流向是個大旋渦，旋渦轉起來像一塊凹面鏡，此鏡經陽光照射， 陽光被聚焦，焦點周圍溫度上升到萬度，所以過往船隻和飛機都融化掉了。科學家作以下試驗，一個大浴盆裝滿水，然後攪動，讓水湧起旋渦，再令強烈聚光燈以十六到七十五度入射角照射旋渦，不久奇磧出現了，一張懸在浴盆上空薄紙突然燒起來，接著科學家把旋渦直徑加大到一百公尺，引入太陽光，發現陽光焦點直徑有一公尺以上，焦範圍溫度高到萬度。百慕達三角區旋渦直徑據說有好幾千公里，存續期間長達六十多天, 在陽光以十度到七十五度角入射時，焦點周圍直徑可達到幾百公尺到上千公尺，其焦點周圍溫度超過萬度。所以飛機，船一入焦點地區，頃刻間化為烏有。即使進入高溫區邊緣，也會引起爆炸和燃燒。甚至連夜間星光，月亮也會聚焦，使夜間誤入此次區航行區遭到不測。
New See Thru Tire
THIS IS THE WAY
Don't need to worry the petrol station air pump is spoilt again...
How soon will aircraft be fitted with these tires......
Radical new tire design by Michelin. The next generation of tires.
They had a pair at the Philadelphia car show.
These tires are airless and are scheduled to be out on the market very soon.
The bad news for law enforcement is that spike strips will not work on these tires. This is what great R&D will do, and just think of the impact on existing technology:
a. no more air valves
b. no more air compressors at gas stations c. no more repair kits
These are actual pictures taken in the South Carolina plant of Michelin.
It will be awhile before they are available to the automotive industry.
