So often these days people will ask me how do I recycle such and such...consisting of items such as appliances, batteries and the dreaded CFL. Just today I stumbled across a great article called 21 Things You Didn't Know You Can Recycle on the Coop America website.
I just stumbled across this great new technology that claims to be able to 'print' solar cells for 30 cents per watt. This is a great article on the technology and their website.
I woke up this morning to this email in my inbox. I have often pondered ways to have the manufacturers wake up about the amount of solid waste they use for packaging. I really like this one.
Hi Greg,
Saw your article about one-use throw-aways in the paper. Here's something kind of related: in Germany (my wife's a German national), household garbage is weighed as it is collected and the homeowner is charged by weight for its disposal.
Even more interesting is that a store is required by law to accept (at time of sale) and dispose of any packaging material used in a product they sell. Since consumers would rather the store pay for the garbage, they often leave such materials behind.
Since the stores themselves want to save money, they have put pressure on manufacturers to reduce the amount of packaging material.
The result is that one sees far less of recycle-unfriendly things like bubble-packages, etc. over there.

In an effort to clear up any seeds of confusion I am dedicating this column to distinguishing the three distinct “flavors” of seeds: heirlooms, hybrids and GMO’s. Heirloom seeds are left just as Mother Nature intended, while the hybrids and GMO’s (genetically modified organisms) involve some level of human intervention.
Heirloom or open pollinated seeds as they are sometimes called, are seeds that have been passed from generation to generation and have stayed true to their ancestral roots by consistently producing the same offspring. This results in plants that genetically are hundreds, or thousands of years old, each developing a resistance to the diseases and pests with which it evolved. When this type of seed is planted and allowed to grow and go to seed again, it will always produce the same plant.
Seed banks serve a vital role in the preservation of the genetic diversity embodied in the heirloom species. Organizations such as The Southern Seed Legacy, Seed Savers International and our own Native Seed Search also have created methods to work with indigenous peoples to preserve such seeds. Of particular interest to me is the way Cornell University in Geneva, New York maintains an incredibly diverse collection of apple and grape plants, boasting over 2,500 apple cultivars and 1,300 grape cultivars.
Hybrid seeds have their own magic. I find that most people are familiar with the term hybrid, which is similar to the process that occurs in nature called natural selection. The process is simple: plant A cross-pollinates with plant B creating plant C. In essence this is how plants and animals slowly evolve. Here is where it gets interesting -- about 150 years ago a gentleman named Gregor Mendel discovered that different pea plants (Pisum sativum) carried different traits and that by selectively breeding these plants he could bring out, or suppress, these different traits. The value in this method is that the “positive” traits in a plant or animal can be brought out, while the “negative” traits can be suppressed.
So now onto real life…a farmer has a really sweet watermelon (A) but it has a lot of seeds, and watermelon B has a great shelf life. By selectively breeding these two plants the farmer finds that the resulting watermelon magically doesn’t have seeds, and he gets a sweet fruit with a long shelf life. The unfortunate part of this process is that hybridized plants often make seeds that are not viable for future generations. So saving seeds is somewhat futile, and of course impossible with “seedless watermelons.”
I get a lot of questions from people that have concerns about GMO’s. Currently these seeds are only available to farmers and as of this year are not available at the nursery or in live plants that you can buy. For a great primer on this topic, see the book Genetically Engineered Food: Changing the Nature of Nature, by Martin Teitel & Kimberly Wilson.
Another term you may have seen applied to seeds is Organic. Simply put, organic seeds are those that have been grown in a manner that is consistent with the U.S. Department of Agricultures Organic Standards. There are organically grown heirloom and hybrid seeds. However, under the current organic guidelines you will not see organically grown GMO seeds because by definition they are excluded.
So carefully select and sow your seeds and soon your imagination’s dream garden will be a reality.
Natah Bowers found a guy in his local farmers market selling seedlings in biodegradable pots made from pressed grass.
Natandidn't mention a source for them, and I've not seenthem before, but I do know about these:
Biodegradable Eco-Friendly Cowpots(TM)
They are made from cow manure.
I found this interesting video describing the construction and use of a DIY compost tumbler on The Compost and Composting blog:
As the former owner of a Mercedes-Benz diesel, the idea of running biodiesel is near and dear to my heart. The older 123-chassis non-turbo models are ideal for running biodiesel.
AZSustainably.com has a great article on making your own biodiesel.
I've been reading this reportby CNW research that provides some insight as to the total energy costs of an automobile broken doen by make and model.
Data includes supplier as well as brand manufacturer energy consumption for the listed vehicles; transportation at all levels of distribution; use of materials (plastics, steel, light-weight steel, aluminum, etc.) and literally hundreds of other factors.
When examined in this light, the current generation of hybrids don't fare as well as some conventional cars. FOr example, my Honda Accord is pegged at $1.96 per mile. The Toyota Prius is $2.19
To quote the report:
"This doesnít mean that hybrids, for example, are a bad choice. That is NOT the intention of the research. What it does mean, however, is that a 2005 hybrid uses less gasoline and produced fewer tailpipe emissions, but costs society significantly more in overall energy costs than conventional Internal Combustion Engine (ICE) vehicles."
Once upon a time, I owned an airplane. The onboard computer was connected to a fuel flow transducer and I could see how much fuel I was burning, effective range, and a bunch of other interesting data.
I've discovered an interesting device that allows me to have the same information in my car: The Scan Gauge II.
It simply hooks up to the ODBII port on your late model car and provies the following data:
Just having this in my car will make me more conscious of my gas mileage, particularly when I see the numbers spiraling down towards awful when I floor it.
One of the bulbs in the light kit of the ceiling fan in my office died the other day.
I wanted to replace all four bulbs with CFLs. Nope. None are made that fit.
Bummer
Ecotality Life brings us pictures of the new Honda Insight. It's gorgeous.
I've heard people comment that it looks like a Prius clone, but the nose is pure Honda.
