These are talks I've given or hosted. Topics include climate politics, energy politics, migration regimes. Highlights include: Julian Allwood on climate politics; David Hughes on 'who owns the wind?'; a conference on the hydrogen economy; Alf Hornborg on technology; Wim Carton on direct air capture. All links are in 'Videos'. Plus, in the "Playlists" section, are links to talks I've given on technology fetishism, climate politics, green growth, migration/Polanyi, East Germany.
1:09:00 For large airplanes + long flights, hydrogen's real competition is probably going to be more or less what we have now (liquid hydrocarbon fuels) + direct air capture. As some point, exhaustion of petroleum may make biofuels preferable. This is not ideal, but probably a reasonable long-term choice, as long as the amount of such aviation is kept to a small portion of the energy mix.
47:05 Not nearly enough is being said about the need to reduce the amount of organic material going into landfills in the first place. Disposal of food waste into the trash is just something vile, yet no one seems to want to confront it directly as an issue. Just from sanitary and esthetic perspectives, this needs to be reduced aggressively.
12:20 GWP of CH4: I think it only confuses things to give GWP for different periods (usually 20 yr/100 yr). It's completely valid to just give the ratio in the immediate sense, and I think that must be about 100 (although I've NEVER seen it given without a time frame ~~~~<-(=(). Give it just as a ratio, and say what the half-life is.
