Researchers Create New Cheap, Shatterproof, Plastic Light Bulbs

hattig writes "US researchers say they have developed a new type of lighting that could replace fluorescent bulbs. The new light source is called field-induced polymer electroluminescent (Fipel) technology. It is made from three layers of white-emitting polymer that contain a small volume of nanomaterials that glow when electric current is passed through them. The developer is promising cheap, hard-to-break, mercury-free, highly efficient bulbs from 2013."

      In both those cases, though, there's a large entity that should be responsible, but isn't being held responsible:

      • For global warming, the power consumption is not the problem. The production methodology is the problem. If our power were produced 100% by solar and wind, with a superconducting grid, there would be basically no additional pollution caused by additional usage (ignoring any pollution caused by the manufacture of the power production and transmission hardware, but at some point in time, that becomes a sunk cost).
      • For plastic bags, it is the responsibility of the property owner to keep things clean. And so on. In both cases, the laws are trying to treat the symptom instead of the actual cause.

      BTW, I can't say I've seen many plastic bags floating around Wal-Mart parking lots. Maybe you just live in an area where people suck. :-D

      You're right about the cost of the bags being spread out across all of the merchandise, of course. But the numbers don't add up for most people. On average, that bag costs about four cents to the retailer. On average, a similarly sized trash bag costs about a quarter. So at about 16% reuse, the grocery bags end up being cheaper. My reuse percentages are at least that high, because I typically pick up plastic bags only when I'm carrying lots of small things and don't waste them on single items or on large items like milk or soda bottles. I certainly can't speak for others in that matter. (Admittedly, this minimal approach to bag consumption is directly correlated with the trend towards self-check registers at stores; baggers at stores tend to overbag; one could probably say, then, that my minimal consumption of plastic bags is caused by me being lazy, but I prefer to put a positive spin on it.)

      Also, the factor of six cost difference between the "free" bags and the bags you actually buy in stores is largely because the actual trash bags are made of thicker plastic and have to be transported across the country inside cardboard boxes that add considerable weight and volume. When you add up the extra fuel burned as a result, even if only a couple of percent of those grocery bags are reused as trash bags, I would expect those anti-bag laws to have an overall negative impact on the environment as a whole. The impact just isn't as visible without the plastic bags floating in the streams, because you can't see global warming. And if you include the additional trash burden from the thicker bags and extra cardboard boxes, the negative impact should be even greater.

      But I digress.

    From a CNN article:

    Doing away with food imports could be seen as understandable if international transport played a dominant role in the food chain's greenhouse gas emissions.

    But in the UK 's case -- where much of the research into the "food miles" concept has taken place -- that doesn't seem to be the case. A sturdy 85 percent of UK food transport-related emissions actually derive from domestic road deliveries according to the DFID. Road freight traffic in the UK grew by 67 percent between 1980 and 2001, with the average journey length also increasing by 40 percent.

    By comparison, international freight contributes 11 percent of UK food transport-related emissions -- that's less than one-tenth of one percent of the UK 's overall emissions, the DFID says.

    Transportation as a whole contributes 2.5 percent of the food chain's emissions, says FCRN. Food refrigeration, on the other hand, accounts for as much as 18 percent (and notably 3.5 percent of the UK 's entire greenhouse gas emissions).

    The whole transport issue initially came to the fore after the "food miles" concept was coined in Europe to illustrate how fossil fuel-intensive the global food distribution network had become.

    But the relative blame that the transport sector should be taking for this is debatable.

    In the U.S., up to 20 percent of the country's fossil fuel consumption goes into the food chain, according to the UN's Food and Agricultural Organization (FAO), which points out that fossil fuel use by the food systems in the developed world "often rivals that of automobiles".

    To feed an average family of four in the developed world uses up the equivalent of 930 gallons of gasoline a year -- just shy of the 1,070 gallons that same family would use up each year to power their cars.

    The average developed world diet uses 1,600 liters of fossil fuels each year, according to the U.S. based Organic Consumers Association (OCA). Only 256 of those liters come from transporting the food, says OCA.
