In response to your “Off the Cuff” (December 16) respondents who gave their opinions of the tea party, of which I’m a member. All six had no knowledge of what we are about. Our mission is to have a government that doesn’t tax and spend us into bankruptcy, as San Diego politicians have done. We want small government, legal immigration only, leaders who are not corrupt and preserve our rights and freedoms as written in the Constitution. We want Americans to be self-reliant. The left wants a reliance on big government constituency. If Christina Sanchez thinks the tea party is about “hate and ignorance,” then she may be the ignorant one!
This is a factual correction for the December 9 “Roam-O-Rama,” “The Green Flash,” by Jerry Schad. He says the green flash is “a complex optical chemistry involving refraction, dispersion, and scattering of sunlight through the atmosphere.” I don’t think chemistry has anything to do with any of those things. I think they’re talking about optical physics, not chemistry.
Jerry Schad responds: Of course, r². It’s all physics. The word “chemistry” was used metaphorically. Physics rules!
Get Light Right
Two issues not discussed (“Best Buys,” December 9).
First, the use of LEDs means you are not burning the old amount of electricity. Good on you for that. A reduction of 12 percent in electrical usage is supposed to help prevent the need to build additional electricity-producing plants in California. They will be built, but they’re trying to build a new energy grid, and a delay will hopefully allow the new grid to be more modern and accommodating to new suppliers of electricity. So if you’re reducing 12 percent, you’re doing your part.
Next is that San Diego electricity has four tiers of billing. The cheapest two tiers top out at 15 cents. The last two tiers finish at 30 cents per kilowatt-hour. By using LEDs, you are using significantly less “end-of-the-month electricity,” which is surely billed at the double rate.
Fascinating stuff, the coldness to the lighting changeover is interesting in itself. The deadline to eliminate incandescent bulbs is getting closer, and many people think it is an intrusion on our liberties. That issue aside, it still requires a bit of experimentation to get the appropriate light for the area using the appropriate type of bulb. Some bulbs will never be replaced again, so getting it right could be a big help.
