What Cool New Tech Would You Put In?
Some of the best new home technology is actually old technology:
- Masonry Heaters, were invented in the Neolithic Era. Unlike wood stoves or fireplaces they burn clean with almost 100% efficiency and require infrequent fueling, only once or twice a day. They also look cool, have a neat ambiance and fuel costs are far lower than any alternative.
- Nickel-Iron Edison batteries were invented over 100 years ago by Waldemar Jungner in 1899 and developed by Thomas Edison in 1901. The nickel iron batteries in Jay Leno's 1909 Baker Electric Coupe are as good as new. Unlike any other home electric backup storage technology they last for basically an infinite number of charge/discharge cycles and have many other desirable characteristics such as immunity to 100% depletion (which destroys lithium and lead-acid batteries) and the are environmentally friendly, non-toxic and 100% recyclable. The only downside is their mass, but unless you will be driving your house around, it's by far the best option. And unlike aluminum batteries, and the Tesla Powerwall, the Nickel Iron batteries are available today.
- Used shipping containers: Build your house out of them. Invented, depending on your point of reference, some time between 1933 (first containerized shipping in Europe) and 1968 (ISO standard published). It's environmentally friendly and your house will be impervious to tornadoes and earthquakes. Container homes have gone from being kind of trailer-park to high-design.
Of course I would want modern options such as photovoltaics and a ground-source heat pump, in addition to the old stuff. So my advice: You will do best to select the best of both the old and new, instead of exclusively one or the other.
