About Earl
|
My name is Earl Killian. This is my personal web
page. I like to read (history, politics, fiction,
science, science fiction), and these pages contain
pointers to a few books I recommend and pointers to
interesting things on the web. I like to muse on the
way things should be and these pages include some of
my thoughts and ideas. I am vegan and a supporter of
animal rights, and these pages include a few quotes
and pointers on these subjects. I have a strong
interest in technology and public policy that will
eliminate the world’s greenhouse pollution. I have three
battery-only powered electric vehicles (a
Nissan Leaf, a
and a
Tesla Model S 85, and a
Tesla Model S 75D,
and these pages have some EV analysis.
(Sadly, I no longer have the Solectria Force.)
I do not currently have a fossil car.
I once built a solar (passive solar heating plus
PV),
straw bale home, but I no longer live there. I currently live
in Los Altos.
My current home has three solar systems (PV, domestic hot water,
and pool) and a heating/cooling retrofit. Finally, my politics,
values, and essays here reflect my interest and appreciation for
non-violence and pacifism.
The opinions expressed herein are my own and do not reflect upon
any organization, despite any association I might have.

Quote for June:
We are the people of the idea, and we rightly fear
that the intellect will dry up the blood in our veins
and wholly check the emotional and creative part of
the mind. And although I said that the fear
But to call ourselves the people of the idea is to
flatter ourselves. We are rather the people of
ideology, which is a very different thing. Ideology
is not the product of thought; it is the habit or
ritual of showing respect for certain formulas to
which, for various reasons having to do with emotional
safety, we have very strong ties of whose meaning and
consequences in actuality we have no clear
understanding. The nature of ideology may in part be
understood from tendency to develop the sort of
language I parodied, and scarely parodied, a moment
ago.
