Cliff Ricketts, 63, a professor at Middle Tennessee State University, is trying to drive across the country, from Savannah to Long Beach, on less than 10 gallons of gasoline, ABC News reported.

Ricketts has refitted three used cars -- two Toyota Priuses and a 1994 Toyota Tercel -- to run on compressed hydrogen, batteries, or E95.

The trip is 2,532 miles, not counting detours for food or motels.

Ricketts himself may make the voyage on 10 gallons, but assistants are towing the other two vehicles using conventionally-fueled vans.

He started his trip by sticking his foot in the Atlantic Ocean near Savannah on Saturday, and hopes to reach the Pacific around Thursday. （點擊ABC網站查看原文）

靠10加侖汽油穿越美國？

???????據美國廣播公司新聞網報道，63歲的中部田納西州立大學教授克利夫·里克茨，試圖靠著不足10加侖汽油從薩凡納驅車到長灘橫穿美國。

???????三輛改裝后的二手車將靠壓縮氫、電池、以及95號乙醇汽油驅動，其中有兩輛豐田普銳斯和一輛1994年的豐田雄鷹。

???????此次總行程為2532英里，為了找吃的或汽車旅館而繞的路不算在內。

???????里克茨本人將會憑10加侖汽油上路，但其助手會駕駛靠傳統燃料驅動的貨車來拖著另外兩輛車行進。

???????周六，里克茨在薩凡納旁的大西洋下水開啟旅程，希望能在周四到達太平洋。
