A Few Observations on Environmentalism
I took most of the day off yesterday to be a part of a family outing at the Los Angeles County Fair. While the kids were on the rides, I wandered off on my own to check out as many eco-friendly solutions as I could find in the “home and garden” area, including a clever new approach to solar water heating for swimming pools.
There was also a marvelous exhibit heralding some of the great American inventors: Franklin, Edison, The Wright Brothers, Carver, Ford, as well as dozens of others: the guy who invented the yoyo, another who gave us Post-it notes, etc. I felt a bit sad that the designers felt the need to limit the focus to Americans, but outside of that, they did a good job.
Now I’m on the train back from Los Angeles, sitting next to a very affable lady of Indian descent who works as an environmental engineer, whose job functions include a great deal of permitting and regulation. So far, the conversation’s been quite thought-provoking. “We regulate businesses, but we educate people,” she says. “As a society, we expect people to make the right decisions with respect to the environment, but not to the extent that they cease to enjoy their lives. I’m not an eco-Nazi,” she smiles.
Solar water heating for swimming pools is rather common. Because swimming pools are considerably cooler than domestic hot water, the solar collectors for them need not be glazed (although glazing would improve their effectiveness) and cost much less than collectors for domestic hot water. Pool covers help to retain the heat. Considering the energy required to heat a swimming pool with gas, it would make little sense not to use solar heating for them.
