The US isn't very serious about efficient homes and buildings even though space heating and cooling and water heating are major energy consumers. Try to build a passive home and find out how many ways it violates building code, is uninsurable and unfinancable ...
Here is a nice list of articles on passive housing..
Somehow this was supposed to be part of the future in 1969
The Honeywell kitchen computer...
When one thinks of computer hardware, they often think of a monitor or a keyboard or a printer. Well, the Kitchen Computer has perhaps the oddest piece of "hardware" I have ever heard of -- a cutting board. Yes, a cutting board! This oddity was most likely added so the food could be prepared right there without having to walk away from the recipe display, considering the Kitchen Computer isn't as portable as a good old-fashioned cookbook (It weighed a staggering 150 pounds).
Other specifications for this system include 4KB magnetic core memory (Expandable to 16KB) and a system clock speed of 2.5MHz. I was not able to find any information about the display, but I imagine it has to be some kind of text display (Who'd want to read recipes using LEDs and binary code?). I also could not find any information about the CPU, or whatever the 60s version of a CPU was. This system is so obscure I had a quite difficult time finding detailed specifications for it. Supposedly the H316/Kitchen Computer is based on the DDP-516 (Also made by Honeywell), so perhaps some of the specifications are similar. However I couldn't find any way to verify that.
