LONDON — Drivers of London's iconic black cabs may soon find themselves competing with accountants to obtain an unusual commodity: chip fat, the oil used to make French fries.
Cabbies, who collectively spend almost $634,000 a day on diesel, are starting to switch to biodiesel, a fuel derived from vegetable oil, to cut costs. Accounting firm PricewaterhouseCoopers is also looking at using biodiesel to power its new London office, due to open next year.
(The success of the biodiesel fuel industry relies heavily on biodiesel testing <http://www.youtube.com/watch?v=s32Ke2VzrqU>, not only at the production level but at the consumer level, where degraded fuel may cause engine failures. Of major concern to diesel and biodiesel users is the very real possibility that water has contaminated their fuel. (See http://www.youtube.com/watch?v=0YcczdvPyAk). The potential catastrophic impact of this problem is discussed at length in this video at: http://www.youtube.com/watch?v=-lh4qhXc_5s&feature=youtube_gdata.
