Just “Food” for thought…..

I just attended a seminar on biofuels….

Switchgrass is one of the leading contenders for biofuel crops (as opposed to wood waste from logging).

To generate the 5 MW that a FF module would, you would need, roughly, 2,900 acres of switchgrass growing. At the very least, an alternate use for this land would be grazing and forage…. so it will reduce potential food production.

This assumes a reasonably efficient boilers/turbines (10,250 Btu/kw heat rate) and…. very high crop yield (no crop failures, storm damage, etc) and low spoilage of the switchgrass crop.. remember, very large quanties (small mountains) of “dead grass” would have to be stored between harvests to fuel a boiler running 365 days a year.

Something to chew on….
