VIDEO: Top Gear looks at alternative fuels in 1990
Watching these 18 year old segments, it seems not a lot has changed. Woollard looked at hydrogen with an early prototype of the BMW Hydrogen 7, methanol, CNG, solar powered EVs and even hybrids. The GM Impact, the precursor to the EV1, even makes a brief appearance while discussing battery electric vehicles. In that pre-lithium ion era, sodium sulfur batteries seemed to be one possible solution to range and weight problem of storing electrons. Although such batteries were tested by automakers, the high operating temperatures (up to 350 °C) limited their usefulness. Nonetheless, the similar Zebra batteries are still being evaluated today and used in some applications. Check out the videos after the jump. Thanks to Joseph for the tip!
