Done. It was a little bitter, but that's just the flavour of the grain. It's satisfyingly nutritious without being full of sugar to mess with my teeth or give me a sugar crash. It'll keep me going for a few hours now.
If I'm smart, with my new-found energy I'll now set about making a proper big meal with vegetables and more substantial proteins with plenty of leftovers to fridge for the coming food crises of tomorrow and the next day and the day after. I might make a biryani. Oh but I should really do my assignments. I really shouldn't open any more tabs.
Damn, I'm hungry now. Having scales handy helps things happen predictably and quickly.
- Stir in a bowl: 50g red sorghum flour + 250g water + butter + salt.
- Microwave on high for 2 mins, then stir.
- Microwave on very low for 5 mins, then stir.
You can make porridge with flour and water. Even better if you have interesting flours you bought in a moment of excitement but never figured out what to do with. Butter and salt help the palatability.

Meanwhile India's incredible train network suffers continuing decades of neglect resulting in poor performance and tragic rail disasters.

What's the scale of this?
Hmm.. would it be too much to paste some of these up around the local schools?
So.. I really don't know chemistry, and these aren't the highest quality references, but here goes:
- 4 mol of iron in a heat pack provides 1648.4 kJ of heat. ^[1]^
- 4 mol of iron weighs 223g. ^[2]^
- Recycling 1000kg of steel saves 642 kWh of energy. ^[3]^
- Recycling 0.223kg steel saves 642 * 0.223 / 1000 = ~ 0.143 kWh
- 0.143 * 3600 = 515 kJ
Huh. So maybe heat packs are a reasonable use of scrap iron's embodied energy after all. Assuming you have a sufficient source of uncontaminated steel filing waste and that it's economical to collect and process into heat packs.
...But only if you're heating your water using fossil fuels using an inefficient method! If your water is heated using solar or waste heat capture or a heat pump^[4]^, which would swing the balance way over to hot water bottles again.
You're not considering the energy required to smelt the iron.
Iron filings (in a collected quantity high enough to make manufacturing these heat packs worthwhile) are not a waste product, they are recycled -- saving the smelting of that much new iron.
Sawdust+iron heat packs are a very useful and non-hazardous product, for sure, but aside from situations where a hot water bottle is impractical, hot water bottle still wins.
