In reply to Lawrence de Bivort's message of Sat, 9 Feb 2008 11:08:28 -0500: Hi, [snip] http://news.bbc.co.uk/1/hi/technology/7234544.stm The heat differentials expand or constrict wax, which provides energy for propulsion. Battery power needed to sensors and communications. It would seem trivial to include a small hydraulic motor driven by the expanding oil, which drives a generator to top up the batteries.
