Welcome to the third to last xx/xx/xx year in our lifetimes  Only next year and 2012 until we wait another 88 years for one.

Now that I have gotten your attention, actually MOST plastic bottles are not evil from a health and safety perspective, but the way that we use them certainly is evil.  I did say MOST, since by far the greatest number of plastic containers are made of polyethylene (PE, recycle code 2), polypropylene (PP, recycle code 5), or polyethylene terephthalate, (PET or PETE, recycle code 1).  These materials are not very apt to leach harmful materials into the contents.

Some plastics, notably polycarbonate (PC, recycle code 7 [7 is a catch all for “other”]) are apt to leach out harmful materials, particularly bisphenol A, strongly suspected as being an endocrine system disruptor because of its potential to mimic estrogen.  Polycarbonate containers are clear and usually thick, while PE and PP are translucent.  PETE is also clear, but usually quite a bit thinner than PC.  Just look at the recycle codes on the bottom.

I have been thinking about sustainability for a long, long time.  Unfortunately, in my scientific analysis, it not possible if we continue on the route that we have chosen.  This is an extremely complex topic, and might even deserve its own, new, date.  I am thinking that Wednesdays might be a good time for it.  This is more speculation than science, so it does not properly belong on Pique the Geek for the long term.

This will be the most controversial topic that I have ever tackled.  I may be dead wrong in some of my speculations, but a lot of thought has gone into them.  I offer no easy remedies but do ask the hard, horrible questions and illustrate them with facts.  I will ask that you, my readers, tell me whether this deserves a new series, uncoupled from Pique the Geek.

Americans for Prosperity has worked closely with the Tea Party since the movement’s inception. In the weeks before the first Tax Day protests, in April, 2009, Americans for Prosperity hosted a Web site offering supporters “Tea Party Talking Points”.

Talking Points: Taxpayer Tea Party   [the Bullet point version, pdf]

Americans for Prosperity — April 2009

— Stop the handouts to Wall Street.

— Stop the Federal Reserve’s printing press

— Stop the federal bailouts that pick winners and losers in the marketplace.

— Stop exploding the national debt, which will crush our children and grandchildren.

— The grassroots MUST take action in order to achieve these goals.

Chimera (genetics)

From Wikipedia

Chimeras in research

In biological research, chimeras are artificially produced by physically mixing cells from two different organisms. Chimeras are not hybrids, […] (like a donkey and a horse) that form a single zygote that will develop as much as it can (in this case into a live mule […]);

in comparison, chimeras are the physical mixing of cells from two independent zygotes:

for example, one from the donkey and one from the horse. “Chimera” is a broad term and is often applied to many different types of mixing of cells from two different species.

Some chimeras can result in the eventual development of an adult animal composed of cells from both donors, which may be of different species – for example, in 1984 a chimeric geep was produced by combining embryos from a goat and a sheep.[8]

Gulf Coast Communities Investigate Oily Sea Mist

by Debbie Elliott, NPR — September 3, 2010

Orange Beach city hall has been inundated with calls from residents with complaints – foam that they think is dispersant, a gray-metallic slick in back bays or seaweed that looks oiled. There’s a heightened sense of environmental awareness, and local officials are looking for a way to determine what’s going on.

Mayor Tony Kennon says that’s why the town hired independent scientists to test the air, water and soil.

[…]

Orange Beach is using grant money from BP for the testing, and posting the data on the town’s website. Mayor Kennon says negative results could affect tourism in the short term, but finding the truth is more important.

Kudos to Mayor Kennon for taking a stand, for what’s right!

The Major is a man of his word.

Monitoring, he is.

Whether we’re even conscious of it, we need and desire a means of discernment.  We seek a measuring stick with which to compare our own individual perspectives with something close to objectivity.  We desire something firm and deeply grounded when the world around us is always changing.  Increasingly, Americans view science as the final and ultimate say.  To qualify my remarks, I don’t caustically dismiss scientific progress out of hand in favor of religious belief.  I do know that science is never static, and that it is a field which is constantly evolving as surely as are all living beings.  To place complete, unwavering faith in science is to overlook the continual process of human discovery.

We have talked about how engines work in the past couple of installments of this series, and now need to bring together some important engineering factors.  We have talked about intake strokes, compression strokes, and others, but only very superficially touched on how everything comes together.

For an engine to work properly, everything has to be coordinated.  For simplicity, we will consider a conventional four stroke, gasoline powered automobile engine.  Diesel engines are in some aspects simpler, and will be covered concomitantly.

Remember, an engine has to do all of the things about which we have discussed, completely synchronized, and EVERY time.  For an engine rotating at, say, 4000 times per minute, this can be a daunting task.

I, for one, hope that this is true, and will be further substantiated:

Study: Petroleum-eating microbes significantly reduced gulf oil plume

David Brown, Washington Post Staff Writer — Tue, August 24, 2010

Petroleum-eating bacteria – which had dined for eons on oil seeping naturally through the seafloor – proliferated in the cloud of oil that drifted underwater for months after the April 20 accident. They not only outcompeted fellow microbes, they each ramped up their own internal metabolic machinery to digest the oil as efficiently as possible.

The result was a nature-made cleanup crew capable of reducing that reduced the amount of oil amounts in the undersea “plume” by half about every three days, according to research published online Tuesday by the journal Science.

The findings, by a team of scientists led by Terry C. Hazen of the Lawrence Berkeley National Laboratory in California […]

Video statement

Earlier in June of this year, I was invited to be part of an interdisciplinary team of wildlife experts, that was organized by the Humane Society of the United States.  There were about five of us from around the country, who work with two HSUS disaster response experts.

We flew into New Orleans with the idea that we were going to spend a week, in the area — accessing the damage of the Oil Spill; looking at the Habitat at risk.  

And trying to come up with an Inventory if you will, of the short term and long term issues, that needed a response.

[…]

Well the hour came, where we finally were — supposedly — given our clearance to fly over the area where the Oil was coming ashore.
