Gas-fed generator

The output of a gasifier is called syngas, or synthetic gas. That is burned in a 100-kilowatt diesel generator, seen on the right, or a modified natural gas engine, on left. The tube running from the Green Energy Machine is piped to the generator. It has been powering all the electricity of the office building of IST Energy since September.

Compared to hauling trash to a landfill, the GEM has far fewer greenhouse gas emissions and is far cleaner than burning waste for energy, according to IST Energy.
