[Digestion] compressing biogas

[Paul Harris]

G'day Michael,

One of my favourite quotes comes from Lord Thomas Dewar - "Minds are
like parachutes, they only function when open!" to which I add that both
are othen used only in emergencies.

You need to look at each of your energy NEEDS (not wants!) and see what
best meets that need. By the time you cook, heat water (which can
possily be mainly solar hot water anyway) and a greenhouse I doubt you
will have too much biogas left, even using waste heat from the
generator.

Liquid fuels are far better for transport use than compressing biogas
(but for short hauls you could use a flexible bag).

All the best,
HOOROO

I will have access to grass clippings from commercial and multi-family area contractors 5 days a week for 8-9 months of the year. Irrigation from all is from well water and the fertilizer is the available commercial brands used in the Midwest. I would like to digest this for the fertilizer affluent and solid matter most of all. I also would like to compress the gas for intermittent use for electrical, water heating, or heating for the greenhouses. If feasible to power a vehicle, it would be nice to have the option of driving to market, to the store, or social events in a bio vehicle.
