A Palestinian-designed electric car drew admiring stares on Tuesday from Gazans forced to use cooking oil to power their cars because of a fuel shortage. "At first people laughed, saying it would not work, now people are begging us to convert their cars," said Fayez Amman. Working with fellow electrical engineer Wasim al-Khuzundar, Amman hooked up an engine to 32 batteries. Driving their small car through the streets of Gaza City, they said the vehicle could travel up to 200 km (120 miles) on a single charge.
