Passive Houses -- Simple Sophistication

I'm always looking for simple systems that work well. Passive houses seem like a great innovation: they are so efficient that they do not need furnaces and are heated by the occupants and other equipment in the house itself. A special heat exchanger allows a steady exchange of air with the outside to keep the house ventilated yet warm.

Unfortunately they are still too cutting edge in the US to make them practical but they are doing well in Germany.

No More Disposable Plastic!

Unfortunately the future is plastic because plastic lives just about forever and will be the death of much of our environment, and maybe us. If you have not already, please see Wall-E  for what our earth may eventually look like. We must do as much as possible to greatly reduce the use of plastic! Here is a seagoing bird that died from ingestion of plastic in the middle of the Pacific: From:  http://ecowatch.com/2013/05/28/california-plastic-pollution-policy-tangled-up-committee/ See also  http://www.nrdc.org/oceans/plastic-ocean/ and many other sources you can find by googling. And read the fantastic book  Plastic-Free: How I Kicked the Plastic Habit and How You Can Too . So my household is eliminating our need for plastic bags and other disposable plastic. No more hard copy newspaper with its plastic bag (see my separate post about my newspaper ). No more disposable plastic grocery bags (thank you for the local plastic bag ban -- now we must m...

The best way to dispose of dog poop

Based on my research, the best way to handle dog poop is to use a reusable pooper scooper and flush the poop down a toilet . Pros: - Sewer systems are designed to handle poop (yours and your pet's) safely and effectively (this was verified by calling the local sewage treatment plant in Sunnyvale, California) - The poop is treated and recycled fairly quickly and safely back into the environment Cons: - Need to carry the poop to a toilet - Need to purchase or make a reusable pooper scooper Here are other alternatives generally listed from healthiest for environment to least healthy. Use a flushable poop bag and flush down a toilet. Pros: - Sewer systems are designed to handle poop - The poop is treated and recycled - Easy to carry bag around to pick up poop Cons: - Flushable bags can "melt" in rain or other very wet conditions - Flushable bags should be kept sealed in another plastic bag before use - Flushable bags are a bit expensive and hard to find - Flushable bags smell...

Wikipedia

Many gleefully trash Wikipedia , but nonetheless it is one of the most helpful and practical resources on the internet along with Google search. While most articles are not eloquent prose, as a whole Wikipedia is the largest and best first stop when investigating a topic. It is a wonderful example of what people can accomplish when they work collaboratively. My hat is off to Jimmy Wales and all the others who created Wikipedia. It's a self sustaining information ecosystem that is constantly cleansing itself and making itself better and better every day. Knowledge is power. Power to the people. It's as simple as that.
