<div class="moz-cite-prefix">Another way to look at this is to say
that the problem is not with the gas producer BUT with the engine
style used.<br>
<br>
An IC engine needs clean gas and most gas producers have a problem
producing clean gas.<br>
<br>
If something like a steam engine was used the gas and all by
products could be burned.<br>
<br>
On one hand a boiler can explode but a tar pond can last many
years. Pick your poison, so to speak..<br>
<br>
Would it be easer to design a safer boiler ? ? ?<br>
<br>
Any engineers out there up to it ? ? ?<br>
