  • No. Humans have lived in walkable villages and towns built at missing middle densities (hundreds to a few thousand people and markets all within walking distance linked by long distance travel corridors you walked to or what you are calling ‘urban’) with local services and a handful of people living on the outskirts.

    Endless suburban seas of <500 people per km^2 were invented for the automobile. The past you are counterfactually claiming exists did not have half an acre of roads, car parks, 4-car garages, set backs and car yards per resident, nor did it have all the services in a central gigantic box building 20 miles away through a sea of identical houses, nor did your rural people demand those in higher density regions provode them with infrastructure for heating, cooling, water and sewerage. Nor did they demolish all the houses around the market just in case they wanted to leave a cart there.


  • Better title:

    EU still setting policy based on projections of oil lobbying organisation in spite of 20 straight years of failure on analyais that can be performed by a highschool student with a pencil and some log paper.

    In spite of best efforts to stop it, targets are exceeded yet again. Set back distance, mandatory consultation with crisis actors, and byzantine permitting requirements for wind to increase again next year. We haven’t thought of anything that will slow down solar yet, but we’ll keep trying.

    The IEA has no credibility nor do wood mac. The most charitable interpretation of their continued failures for projections (sometimes even failing to project that solar will ever grow or coal will ever shrink to the previous year’s numbers) on the energy transition after having the flaws pointed out repeatedly is rank incompetence. Given the board’s career history and the membership criteria this is a pretty long reach though.


  • Thermodynamically you start with ~55MJ/kg available if you were to oxidise the methane.

    Then you end with 750g of carbon that would give you ~35MJ/kg were you to oxidise it or 26MJ. And 250g of hydrogen that would give you 120MJ/kg or 30MJ

    If it were 100% efficient and free then for the cost of the input methane you could get the same amount of thermal energy with a solar panel or wind turbine and a resistor. This is a science proof of concept so expect single digit efficiency which is unrelated to pkssible scaling

    As far as ways of greenwashing fossil methane go, it might actually have some potential positive effect, although the hydrogen produced will not be competitive except as backup energy.

    As a thing to do with waste-emission methane it might be better than burning it. You’d still need some way of storing the hydrogen that is competitive with overbuilding solar + 4-12hr batteries (none presently exists).







  • If the garage is used as internal space, then row houses are plenty high enough density. The occupant could have a much nicer back yard without the setback (front yards are car infrastructure), but the road is not too wide, just awful to be on.

    If we assume 1.8-2.1 people per house, then these blocks are about and 300m^2 with about 100m^2 out the front in tye public spacs e per house (property boundary to middle of road]. 5000 people per km^2 for the residential area, assume 50% as much commercial/parks elsewhere (~100m^2 per resident) and you’re at over 3000 people per km^2

    This is in the ideal missing middle range if a little bit low, it’s just awful missing middle (that will probably also have its density ruined hy a sea of carparks in the commercial areas and a highway, but that’s a separate issue).
