Your Big Bear and Catalina sighting story reminds me of when I lived in LA, actually Venice, in the mid 80s to mid 90s. One winter, I think it was 1990 or 1991, for a week or so the temperature went down onto the low 20s and we heard that it had snowed on the San Gabriel range of mountains just inland from coastal LA. Now the San Gabriel range is invisible for like 99% of the time for years on end due to the polluted air. By then I had lived in LA at least 5 years, and suddenly you could see the mountains! It was a shock.
In 75 I lived in Newport/Huntington Beach living on the inland cliffs and one day after living there 4 months Catalina, 23 miles, all of a sudden popped up quite large!! next day I saw Big Bear 40miles NE. Sadly was the last time too. Living there was like smoking 2 cigarette packs/day so left a few months later.
As for green energy Penn media just announced Michigan.gov reports RE costs 25% less than coal does in their state by a board appointed to track it's RE policies. So it's relly at parity or better in many places now. The economics is getting harder to ignore and try to explain away.
And by no means the only. It's been happening for a while on well done projects. Some have paid off already and now almost pure profit other than maintaining them.
I agree with you that the supposed greater expense of bioplastics and other green materials is something of an illusion. Ot all depends on how you defined your universe and what you consider "costs."
I was a teenager in the SF Bay Area during the 1960s and know what you mean about the environment changing. I remember when the air there started to change from the crystal clear we only have now up in the mountains. I also remember a year not much later, I think it was 1974, when we had an unprecedented clear air day after some spring storms, where you could see from San Francisco all the way down the Peninsula, the air was so clear. It was a startling reminder of what we had lost.
Many seem to think bioplastics, RE, etc green things are more expensive That isn't the real facts. While some are and just greenwashing, true greenness is very cost effective as it SAVES things. Mostly when one saves it costs less.
The most effective green is using less to get more. If the designer/engineer is any good they do that automatically.
While I'm a social progressive I'm very much a real fiscal consevative, IE cheap, so want the least costly by full cost accounting. In almost all cases real green costs less in life costs.
Like oil, it's costs are huge and not in it's price but in our tax payments. 30% of the US budget goes to persian gulf military, oil wars, direct subsidies, pollution, $500B/yr trade deficit, $ that will never make another US job but support oil dictators and terrorists, etc. Add these all up and oil price would double.
Yet green energy most of the costs is labor, materials that make far more jobs, better economy and avoid all those other costs oil, coal have.
I've just found PV laminates costing only $.50/wt retail!!!!! Other panel with junction boxes only cost $1/wt, 20% of 6 yrs ago!! Sunelec.com.
I'm doing a bid to produce 2kw windgenerators costing under $2k/kw. At the same time I'm doing my own design for production.
Both these above over 3 yrs are well under the cost of coal, NG or Nuke retail costs. So go green and for under 3 yrs eergy payments, one can have almost free energy for 25-50 yrs!!
So those of you sticking to FF hold onto your wallet as it's going to be assulted badly. Best is start becoming energy independent or just use a lot less though smart living, insulation, etc.
Designers, engineers better go that way too or they will be left behind.
As for kids, they are far smarter than many give them credit for. They are watching Repubs and so called conservatives run our country into the ground fiscally and pollution wise. Their idea of freedom is make as much profit even if it kills people and leaves the bill to the taxpayer. Kids are smarter than that.
I'm not sure how many here remember just how bad the air, water got here in the 60's, knda like China now, when rivers caught fire and 50% of rivers, lakes, bays and seas were so bad. Now Tampa Bay is almost back to producing great fishing, etc because of green thinking which really is the old version of being conservative which this generation of repubs have fprgotten.
I've interviewed many of these young professionals at large electronic component producers (like TI) and consumer electronics companies. They are very knowledgeable about environmental technology, global regulations, and carbon emission evaluations. These are not PR and marketing people. I was surprised to find that many of these companies take their environmental policies and initiatives seriously. As recently as five years ago, it seemed most large corporations merely dabbled in environmental policies -- mostly they were simply complying with regulations. That has changed significantly.
I agree. Guilt is certainly a powerful motivator. Even though I've occasionally joked about needing some Guilt-Away Spray, I think it can be a positive motivator for good reasons, and this is one of them.
Those kindergarten impressions can last a lifetime. Part of the concern for the environment it might be fueld by guilt. A bright young professional take a job at Mobile, GE or TI and has concern about the company's practices. That professional may be carrying around some of the kindergarten impressions you described. So guilt about working for a company that may not have a great environmental record could prompt these professional to get behind positive changes.
Thanks, Rob, those are thoughtful and educational comments on this subject. Regarding younger folks, I remember when my niece, born in 1985, came back from kindergarten and talked about saving the planet. It was a real surprise to realize that what I had protested about was finally becoming mainstream and taught in schools. Glad to hear that this is the case in many large companies.
aleemengr, there are actually two different material categories in the story. The first material, based on ruthenium, was developed in the lab and that study appears to be mostly a chemical one. I saw a wide variety of applications mentioned that this material could be applied to. The second two materials are plant-based, and they are created and sold by Cereplast. I suspect the company has some MDS you can check out.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Engineers at the University of California, San Diego are designing a robotic arm that takes inspiration from the loose, flexible, yet very strong structure of the armored plates on a seahorse's tail.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
