iPhone 3G Yes!

July 19th, 2009 admin

Though not an i-Phone addict yet, I am now an iPhone user. From the time I have been introduced to the iPhone, by friends, I have constantly admired the versatility and the sheer quality of the product. And after a few bad experiences with our previous phone service with Sprint we decided to switch to AT&T. It has been a relatively seamless switch. But the highlight has been the iPhone.

Even before I opened the iPhone box I was impressed with the immaculate packaging. The phone was surprisingly easy to learn using, and any non-obvious features were easy to search for on the web. The ability to download the applications of our choice and even develop your own applications is a tribute to and celebration of innovation and creativity embodied by the iPhone. I could rave about this Swiss-army knife of mobile gadgets or I could argue that no one really uses a Swiss-army knife in normal life. Indeed, I have not yet figured out how best to effectively use this phone. Some of the features that translate into time and money savings are the GPS when you are lost on the road, the ability to look up the Internet to get answers to simple questions when you are in doubt, the ability to entertain yourself when you have time to kill (books, podcasts, puzzles, YouTube, newspapers, iPod music), the ability to shoot video and ship them to your friends (thus avoiding hours of procrastination) and the ability to synchronize the contact list and calendar entries with Google. In short, this tool allows you to use small pockets of time more efficiently, either the educate or entertain yourself, or to rewind. This is important, to me at least, because then the time with family does not need to be compromised for trying to rewind in my own way. Simple example: if I feel like listening to Louis Armstrong I can listen to him and other jazz artists on Pandora while driving back from work. Then once I am home, I can spend time with Kavita, as she wants me to.

So, finally, thank you, Anu, Shankar and Sandeep, for live demos and persuasive nudges, and thanks Kavita for the final push. I’m on board and I am enjoying the ride.

(I posted this entire entry from the iPhone. I am getting very good at typing on this, something I was not so sure about only two days ago.)

What should I do with my used PVC shower curtain liner?

July 19th, 2009 admin

When replacing the PVC shower curtain liner today, I was wondering what kind of plastic it was and whether it was recyclable.

Here is what I learnt about the various types of plastics. The following list is from Wikipedia’s article on Plastics.

  1. PET (PETE), polyethylene terephthalate: Commonly found on 2-liter soft drink bottles, water bottles, cooking oil bottles, peanut butter jars.
  2. HDPE, high-density polyethylene: Commonly found on detergent bottles, milk jugs.
  3. PVC, polyvinyl chloride: Commonly found on plastic pipes, outdoor furniture, siding, floor tiles, shower curtains, clamshell packaging.
  4. LDPE, low-density polyethylene: Commonly found on dry-cleaning bags, produce bags, trash can liners, and food storage containers.
  5. PP, polypropylene: Commonly found on bottle caps, drinking straws, yogurt containers, Lego building blocks.
  6. PS, polystyrene: Commonly found on “packing peanuts”, cups, plastic tableware, meat trays, take-away food clamshell containers
  7. OTHER, other: This plastic category, as its name of “other” implies, is any plastic other than the named #1–#6, Commonly found on certain kinds of food containers, Tupperware, and Nalgene bottles.

Three main things I learnt are:

1. The biggest difficulty with recycling plastics is that these types tend to get mixed up when people try to keep the plastics aside for recycling, and separating them is a labor intensive problem - often not worth the trouble - and thus, unfortunately, sending all this plastic, irrespective of the good intentions of recycling them, into landfills.

2. PET (Coke and Pepsi bottles) is very different from PVC (Gatorade bottles and my problem at hand, shower curtain liners), both of which are different form HDPE (milk jugs and detergent bottles)! PVC if mixed with PET, can ruin not only the batch of PET that is being recycled, it can even hurt the recycling machine! So be careful with recycling PVC.

3. Polystyrene (PS), which is used in “styrofoam” to-go food takeout boxes, is typically not recycled because it is not cost-effective to do so (maybe because of how cheap it is and also because of the food contamination that goes with the territory). It almost definitely ends up in landfills, and only centuries of wait may see its end. Along the way, during those centuries, who know how much damage it causes to the living things that inadvertently ingest it.

So, all in all, recycling is not as easy as dumping anything plastic into the recycling bin; it is important to be aware of the differences between plastics. It is important also to educate ourselves about how to ensure that what we think we are recycling actually gets recycled. Styrofoam is best avoided. Maybe we need to leave repeated comments on restaurant websites that they should avoid using styrofoam-based to-go boxes, and instead switch to paper (like Chinese-takeout buckets).

I am not sure how well I will be able to follow all of my own suggestions. The intention here is to start thinking about these issues.

A couple of other interesting websites I found:

1.  http://www.townofcary.org/depts/pwdept/recycling/trivia.htm

2.  http://www.greensangha.org/PVCaction.PDF

Now, the question still remains. What do I do with the used PVC shower curtain liner? I don’t know if Cary recycles PVC. I need to find out and act accordingly. And maybe it is best to stop buying these liners, and instead switch to a cloth-only liner or some bio-degradable variety.

Have people forgotten Shiva?

July 19th, 2009 admin

Hinduism has a notion of trinity - three forces that drive the universe. The trinity consists of the creator, the sustainer and the destroyer (personified respectively by Brahma, Vishnu and Shiva). I do not claim to know the spiritual aspect of this concept. However, the applicability of this concept to the physical things in our lives is almost obvious. Everything physical comes into being, serves its purpose during its lifetime and is (or rather, should be) eventually destroyed. These three forces must guide each other in an eternal cycle, rather than in a linear progression. That which is destroyed, must contribute to the creation, and that which is created must be destroyable. This is not philosophy; this is just the principle of equilibrium and balance.

The spark of a creator’s idea, must be weighed and studied for the sustainability and fesibility of that which the idea generates. Once the creative force is assured of the sustainability and usefulness of its creation, it must also analyze the destructibility of the creation. Only when the idea passes both these tests - useful when in existence and destroyable when not useful - is the creation sustainable. To be destroyed does not mean to make it go away or vanish. Being destroyed here means to change form. The death of one is the birth of another. The death of a wine glass when it slips from your hand and shatters is the birth of a hundred pieces of glass. The death of those hundred pieces in a kiln if the birth of liquid silica, which dies to takes up another form when shaped into a glass window.

Sunstainable creation is dependent on reliable destruction, which in turn is dependent on future creation. In our lives nowadays, I wonder if the creator’s dependence on the destroyer is being slowly forgotten. Things are getting created with no concern for its destructibility (and often with no concern even for sustainability). Creation is driven by sustainability and usefulness, which is fine. However, the second part of the pre-creation analysis, destruction, is becoming only a secondary concern.

A case in point is plastics. Plastics are almost irreplaceable in certain situations. However, its usage cycle has overflowed its equilibrium bounds. The ease of creating plastics and the convenience of sustaining plastics have together overpowered the responsibility of destroying them. The durability of plastics, which is often a big positive, makes it equally hard to destroy. And when used in scenarios where such durability becomes a liability, the benefits of plastics are questionable. Wikipedia’s article on Plastics has this, somewhat scary, line. “Due to their relatively low cost, ease of manufacture, versatility, and imperviousness to water, plastics are used in an enormous and expanding range of products, from paper clips to spaceships. They have already displaced many traditional materials, such as wood; stone; horn and bone; leather; paper; metal; glass; and ceramic, in most of their former uses.” Notice that all the things that plastics have replaced are either natural or biodegradable, or both. I agree that there are some organic palstics in nature, and there are some man-made biodegradable plastics; however, the point I am trying to make is not hijacked by either of these. From wall-to-wall carpets to the teacups used by chai-wallahs in roadside dhabas, from ziploc bags to microwaveable idli-plates, plastics have slowly but surely taken over our lives. In this takeover, not only has the senseless overuse of plastics created a dangerous imbalance in the natural world, it has paralyzed us into a state of helplessness compliance. Plastics have destroyed the destroyer.

In many uses of plastics, they are certainly replaceable by other, more responsibly created, products. We, the users and sustainers of plastics, should vote down the creators’ decision to create them by reducing the use of plastics where possible (take your cloth grocery bags with you when you go shopping, use glass or steel dinner ware at home and paper or corn-based plates at picnics). When usage is not avoidable, we can restore the balance somewhat by paying due homage to the destroyer (use plastic that is recyclable and recycle the plastic that you use). A moments thought before consumption can not only help restore some balance in the cycle of creations and destruction, it can also help restore a sense of control over our destiny.

On my part, I make it a point to visit the Shiva temple of Cary once a month. It is a large, airy temple, with the added convenience of a drive-through pradakshina (the act of revenential, clockwise, walking around a Hindu temple’s central structure). Each time I go, the priest walks up to my car, greets me, and asks, “What do you have?”. Upon telling him about my problems, he points me to the correct deity to go pay my respects to. His utterance may seem strange for temple-talk, “Go to number 4″, but what he really means is, “Deity no. 4 will rid you of all your troubles and send you home free and uplifted”. The temple, for some strange secular reasons, likes to identify itself with a small, unadorned, non-ostentatious, green sign with white lettering that reads, “Cary Recycling Center”.
