So, Mu, are you advocating HG methods combined with substantial depopulation?
Some of the stuff I edited out of my posting for the sake of not writing another even-lengthier GG3 essay:
Electricity for lighting is easy. LEDs. Yes, it means that indoor lighting basically consists of nightlight-level lighting for general room light, plus task lights for reading and cooking. But it can't cause a house fire.
Many appliances that use motors could be human powered if properly designed. Of course we already have manual eggbeaters/mixers, ice crushers, and so on.
I did a lengthy project on laundry and figured out how to use manual power input at maximum efficiency, but building the machine will require a metal shop. However, my twintub washer does 5 lbs. for 60 watt-hours which is the equivalent of an incandescent bulb left on for an hour.
Floor cleaning as such can be done with a combination of a broom and long-handled dustpan, and a damp mop. As for beating rugs, I dare you to try it, and report back what you discover. In point of fact, most rug cleaning can be accomplished with a manual sweeper, and these are still made (some will also sweep floors). The vaccum can be used only occasionally (as in, once a month or less). For above-the-floor dusting there's the oldschool dust mop.
Smoking of meats etc. doesn't address the issue of dairy and eggs or the issue of keeping vegetables from going rotten. In fact my design plan for refrigeration involves a clustered housing or cohousing layout, where there is a large (therefore intrinsically more efficient) hyperinsulated refrigerator and freezer in the main building, and the individual/family units clustered around it would have micro fridge/freezers sufficient to keep a minimal supply of food i.e. the gallon of milk, half dozen eggs, quarter pound of butter, a head of lettuce, and a few pieces of fruit, that kind of thing. Plus ice cream. Can't do without the ice cream:-).
Cooking is still the big open question. Wood fires in and of themselves may or may not be sufficient. Solar concentrators are a no-brainer in appropriate weather.
Now onward to tools. A power saw consists of only one moving part, an electric cement mixer consists of only three. A power drill has an intermediate gear train so you can count that as one assembly or as a cluster of individual parts.
The elemental machines are the lever, the wheel, and the inclined plane.
A wheelbarrow, properly designed, puts 80% of the load on the front wheel. Thus an individual can move 300 lbs. with a total weight on each arm of 30 lbs. A two-wheeled barrow enables putting 100% of the load on the wheels, enabling one person to move a half ton or more easily depending on the surface it's being moved across. Note that plain steel wheels can & should be used for these applications, thus reducing rubber consumption further.
The wedge is nothing more than a derivation of an inclined plane, and from that we also get the plow. A plow mounted on a wheeled frame with a seat and a sun shade, all of this pulled by a couple of horses, takes the "backbreaking" out of tilling the soil. A similar unit, minus the plow, and with a cutting bar and a platform behind it, makes the harvest manageable.
As for bicycles, rubber is a problem but not insurmountable. As for the roads to ride them on, something like a wide sidewalk will do.
I predict a renaissance of toolmaking, concentrating on the most efficient uses of whatever energy sources are availble including humans and animals. Simple machines will make a comeback. Pick any area of technology that interests you, research the history of it as far back as the middle of the 19th century, and you can see where we're going.
As for reuse and recycling of raw materials, look no further back in history than the end of the Bell Telephone System in the US and its equivalents overseas. Every piece of equipment, every component, and every foot of cable was designed to be repaired and reused indefinitely (typically on a 40-year lifespan between major reconditioning), and then when it could be repaired no longer, melted down for raw materials to make the next batch. Landline telephony, by the way, is far more efficient than wireless telephony on all counts. And for entertainment, a simple radio will do: there the tradeoff is between a) analog AM & FM, with a greater amount of energy input at the transmitter but far simpler equipment all'round, and b) digital broadcasting, with a far lower power requirement at each end (a decimal place or two at the transmitter) but more complex (integrated circuit based) transmitters & receivers.
Welcome to eco-industrial design: doing more with less, for fewer, for longer.
And if we don't get the population levels down to about 2 billion, no matter whether we go into full HG mode, we're still screwed.
