>1° Conductive systems (if not localised) are dispersing the heat, so this is highly energy inefficient.

well this is true

>2° What old way?

old way of not ramping up insanely hot temperatures inside during winter.

>3° If you have 60-70% humidity in air your are fucked, it won't help. I know old people with both ceiling fan and air con, during hot days they use the air con.

who has that kind of humidity as regular? circular fan during hot summer dirrected into me beats idiotic AC directed into the room every time...have I mentioned I get fresh as opossed stale air with a circular fan?

>4° How a fireless cooker is low-tech? How?

true its not low tech.

>5° This is pure shit, high tech cooker are insulated (a good example is the rice cooker), it is way more efficient than fire.
>(Nuclear power-plant is the most efficient source of power, fire is garbage)

I think he was refering to electric stove cookers which are notoriously inneficeint but safe compared to gas (or a nuclear plant).

>6° Complementary solution, work in small cities without the need to drive 15km or so.

nothing to add here other than the expensive problem of centralization

>7° Lol, CNC means high speed, way more efficient than a human. Try to make something as fast with a old lath and milling machine. Clearly you are not a machinist.

here is what you dont get - automating everything IS NOT ECONOMICAL. In fact automatization is highly expensive (creates centralisation and shipping costs) and its only economical in specific cases when you make high quantity.

>8° Being this retarded is beyond my imagination. A low speed train (1h30-2 hours) ticket cost me 30€, when the high speed low cost equivalent (same distance, but 40 minutes) cost me 10€.

it costs (you) that because its subsidized by the government not because the costs of creating maintaining it are less read the article you mong
