Some of the most efficient ways to exercise are weight lifting about 24 repetitions of each exercise to complete exhaustion and interval training like some kind of sprinting. Lower weight higher repetition weight lifting (meaning about 24 reps) done to complete muscle exhaustion (lift until you can't lift a single time more) can actually build muscle even faster low repetition with a heavier weight. A study on this is here: http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0012033 N. A. Burd, et al. “Low-Load High Volume Resistance Exercise Stimulates Muscle Protein Synthesis More Than High-Load Low Volume Resistance Exercise in Young Men,” PLoS ONE, vol. 5, no. 8, p. e12033, 2010. Interval training works so well partly because you move fast turning on more fibers. Each muscle fiber in a skeletal muscle either contracts fully or not at all. You lift heavier weights or move faster by contracting/engaging more muscle fibers. So fast motions in interval training...
This post is about housing technology. Basically there isn't any. There is technological and other improvements for housing but in the US basically none of them are put into widespread use. There are heat exchangers that keep warmth in houses while letting fresh air in I have heard they are getting more and more common in northern Europe. There floor heating system using electricity or hot water. Floor heating is one of the most efficient systems around and are standard in South Korea. Housing can have thick walls like strawbale houses, if you don't like these modular houses built in factories have excellent insulation. There are passive heating systems that face most of the windows south and have a long overhanging roof that shades the windows from the high summer sun and lets the low winter sun in. Leaf trees planted on the south side of a house shade the windows with there leaves in summer and their bare branches let the sun in while north side planted trees keep cold breeze...
We live about the the same everywhere, even though there are so many things to take advantage of locally. In sunny places like Utah and California I sill rarely see solar panels on houses - certainly little more than in rainier places like New England. Then we also grow green lawns in the desert, desert cities look just like rainy weather ones. Places with warm mild sunny weather rarely have more bicycle commuters (or even less) than rainy places like Portland, Oregon or cold snowy places like Madison, Wisconsin. Portland and Madison actually have more bicycle commuters than most places despite their weather to the credit of their cyclists. We eat about the same north, south, east or west. Different vegetables and fruits grow best in different places but we actually vary little in what we eat. Most of our vegetables and fruits are trucked from San Joaquin Valley, CA requiring lots of diesel. This is getting dangerous because San Joaquin is having a drought possible being made worse by ...
