Probably the last new show until August 12th, although I might be able to use the call–in feature while I’m at the beach in Manitoba. Mostly I talk about transport ― filling stations for motorcars versus charging stations for battery–electric cars, hydrogen propulsion for trains or perhaps airships, and especially the remarkable scaling properties of steel wheels on steel rails with overhead–wire electrification.

2023–07–11 Dialing in this time, to check that this should work for ASFO shows while I’m in Canada the next few weeks (I’ll leave the HNtW timeslot for repeats), I finish the Hoyle et al piece from last time, and then read Nuclear Reactions in Stars Without Hydrogen (Astrophysical Journal, 1952) by EE Salpeter and Primeval Helium Abundance and the Primeval Fireball (Physical Review Letters, 1966) by PJE Peebles, from the same source, and a bit of Hans Bethe’s famous 1938 “Solar Phoenix” paper, Energy Production in Stars (Physical Review).
