San Francisco launched project Greasecycle just before Thanksgiving, a free citywide effort to collect and recycle fryer grease from the city’s restaurants. The city will collect the grease, turn it into biodiesel and power the city’s vehicles with it – including buses and firetrucks. The benefits for the city are twofold: they get an almost-free fuel source that burns cleaner than traditional fuels and they solve the illegal grease-dumping problem. According to the San Francisco Chronicle, illegal grease dumping costs the city about $3.5 million annually by causing “heart attacks” in the sewer system – congealed grease clogging up the works. The city also plans to start picking up household cooking grease in the near future, reminiscent of WWII era bacon grease collection (but back then it was used to make bombs).
This is our first time covering the Earthracer, a racing ship using Biodiesel as fuel, as it attempts to circle the globe. We are covering it now because a friend and one of our first G Living Live host, Ziya Tong, did a show on the ship and its crew for the Canadian Knowledge Network.

Earthrace is a 78 foot wave piercing trimaran designed by New Zealand navel architect Craig Loomis Design Group and was built by Calibre Boats.

Earthrace has concluded its sea trials and Skipper Pete Bethune is confident the boat is structurally sound to circumnavigate the globe.
