Off grid living
Because of age I have no physical connection with off grid living but
have been studying the Sustainability problem for a long time. I feel this
issue relates directly to gasification because biomass and gasification
would be a major strategy for getting local power and possibly making
liquid fuel. Off grid living fights Global Warming, destruction of natural
resources, pollution, and can make jobs. Reducing energy consumption is a
universal way of reducing all pollution.
Two of the tactics are reducing essential travel and reducing
heating costs. Walking to work saves the earth. Travel costs are reduced by
building towns perhaps 1 square mile in area that are densely packed with
human activities such as apartments, factories, and general purpose stores.
Cities are composed of distinct towns. This means that most of business
travel can be done by foot, bicycle, horse, or low speed public
transportation thus saving large amounts of energy.
It can easily be shown that apartments in comparison to houses
reduce heating costs by a factor of at least two for geometrical reasons
only. With good insulation this cost may also be reduced by a factor of
two. Add in solar heat from green houses around the building, heat pumping
by windmills, and solar heat from reflectors and it would take almost no
biomass to heat the building. Apartments are the best way of lowering
consumption because we need them anyhow and they last a long time.
Solar mirrors are far more important than solar voltaics because
they are cheaper in light gathering and because they deal with heat as well
with electricity. The same mirrors can be used with steam engines for
making power. These steam engines can be used with biomass for cogeneration
when the sun doesn’t shine. Mirrors can increase solar panel power, make
hot water, dry crops, fuel, and food, and can power air conditioning.
Tactics used to create and save biomass energy are engine
and power, engine driven heat pumps, solar mirror energy, biodigestion, use
of manufacturing waste heat, gasification, small scale manufacture of
liquid fuels, and in dwelling manufacturing,
Fertilizer would come from sewage, manure, biomass ashes, and
later from the sea. It has to be carefully used close to buildings because
later the mines will be exhausted. Agriculture and food preservation must
be close to cities. Energy crops will be an important method of making
sewage into food fertilizer because combustion may destroy medicines and
other organic pollutants in sewage.
Jobs must be created by multiple product local factories that
specialize in commodities that we really need. Workers must have skills
that enable them to shift from one product to another. Factories that have
office space, a machine and welding shop, and heat can make special tooling
for many products. Some of that tooling such as robots would be adaptable
for anything. Kermit Schlansker kssustain at gmail.com
