How is it possible to safely use carbon monoxide as a fuel?

Is there anything that will allow carbon monoxide to be used as a fuel? It is quite toxic, but has attractive properties otherwise (only produces CO2 with no water, also no smoke or soot). Aside from a permanent spark, or a pilot light, I can't see any way of doing this.

Is there some catalyst that will help the reaction? Apparently, platinum can be used as catalyst between hydrogen and air.

• A fuel for what? If you wanted to heat with it, then its conceivable that a pilot light would do the job. If you're wanting to use it in an IC engine, that has been done via wood gasification for some time, though that yields a blend of CO and H2. Any leaks in the system could prove fatal though, so I wouldn't count on it being the next big thing. – Jason Patterson Mar 20 '16 at 16:00

During WWII many cars were powered by a gasogene engine, which transformed wood or charcoal into a synthetic gas composed by $$\ce{CO}$$, $$\ce{N2}$$, $$\ce{H2}$$ and $$\ce{CO2}$$. Thus the use of $$\ce{CO}$$ (albeit not as a pure gas) as a fuel is not something new (the former use of piped coal gas for house heating and cooking has already been mentioned above). I am not sure however about how safe those gasogene engines were.
