Oh indeed. I was referring to how the community itself views it by their choices to flag or not flag things. But thank you for the confirmation of my understanding.
There are several books which explore this concept, viewing history through the lens of energy systems available to and utilised by humans.
Vaclav Smil has written two of these, Energy and Civilization (2017) and Energy in World History (1994). They cover much the same ground, though with different emphases.
In the past year there's a new book on the topic, Energy's History: Toward a Global Canon, by Daniela Russ and Thomas Turnbull, though I've yet to read it.
3/4 cup is about 315 ml, or another 315 g, for just over 400g cooked weight. The linked article does not make clear whether or not the 300g is dry or cooked weight.
The original paper describes two protocols, short-term and long-term (2-day and 6-week respectively) of 100g dry oats and 80g dry oats prepared for each meal. That's a generous but not outrageous serving size, and the former comes out to 300g oats per day over three meals.
The overnight oats (rolled or steel cut) will cook much faster after they've soaked up liquid. If you're adding ingredients such as egg (two per 1/3 cup s.c. oats) this takes care of the raw elements as well.
The face value of a coin may be driven down, based on the exchange value of the currency itself. A coin with a nominal value of 10 but, say, a specie value of 11, is literally worth more melted down than in exchange. This is the dynamic of the Law of Oresme, Copernicus, and Gresham (usually referenced simply as "Gresham's Law").

More generally, when a product's exchange value differs from its production or use value, paradoxical results occur. Gresham's Law, Lakoff's "Market for Lemons", arguably the Jevons Paradox, the phenomena of wine and audio kit pricing divorced from any defensible consumer capacity at discrimination, and enshittification all seem to fit this with reasonable amounts of shoehorning. Also my own "tragedy of the minimum viable user".

And that means people will buy and sell it for the specie value. The specie value is the value.
Bullion coins like silver can be worth exactly what the metal is worth, or more. Never less than what the metal is worth.
Just because a gold philharmonic coin might be minted with a €100 nominal value, doesn't mean that it is worth that. If you think so, I'll gladly buy all your gold coins for their nominal value.
I believe that you two are not disagreeing in logic, just misunderstanding each others intended meanings.
When you said "a coin can never be worth less than the metal it contains", I think you meant "no matter what number is on the coin, its value is always equal to or greater than the value of the metal"; but dredmorbius misinterpreted your comment thinking you meant "the number on the coin must always be a higher value than the metal would be worth if it wasn't shaped like a coin".
AKA when carlosjobin wrote "be worth" you meant "value to sell", but dredmorbius thought you meant "value written on it".
I might be wrong, maybe it's me misunderstanding one or both of you - in which case please correct me - but I'm fairly sure you're both correctly thinking the same thing while incorrectly thinking the other person isn't.
"Value" one of those horribly conflated terms of economics. For starters there are the relatively well-known conflicts between production cost value, use value, and exchange (market) value. The discussion here adds another element: the distinction of notional currency value vs. commodity value of underlying specie or substrate.
The absolute nature of carlosjobim's claim makes it fairly trivially falsifiable, however. Since nominal value is a value, if the face value of a coin is lower than its specie value, its use as currency meets his absurdity condition, "Of course a coin can never be worth less than the metal it contains...", but that remains its legal tender face value. As money, that is, an exchange token socially recognised as having a universal value, the coin is exchanged below its commodity value.
As a commodity, that is, metal (or other material) specie, the same item may have a different and higher value, but in this case it's not one which is universally accepted within a given market, but rather is dependent on the specific local market supply and demand of that specie. The coin-as-commodity is also subject to differential valuation based on characteristics --- assayed purity, weight, etc. --- which must be assessed on an individual basis for each coin.
In practice, where specie coin was used it virtually always traded at a premium above the commodity value, known by the term seiniorage, which I interpret as the trust value imbued by the currency issuer. My (unorthodox) view is that seigniorage exists in all monies, and is efectively the total basis for value of fiat systems such as paper or credit-based financial systems. The value of such currencies is a market vote on the trust in the issuing entity (and/or the lack of viable or accessible alternatives).
But again, coin-as-money has a value equal to its notional face value. That the face value may differ from its commodity value can of course occur. My argument is that this makes the exchange one of commodity trade rather than financial trade, and that ascribing commodity value to coin or face value is a misdirection.
Some years back looking into what money is, I realised that the names for virtually all currencies can be traced to either weight (pound, peso, dinar, penny, shekel, kopek, livre, baht, etc.) or division (dime, quarter, cent); or quality (dollar, crown, royal, franc, renminbi), sometimes appears as a signifier of value, e.g., the florin, yuan, or yen. I'd classify toponymic names (e.g., afghani) as referencing quality. There are the odd exception, notably Bolivar, the Venezuelan currency named for Simón Bolívar, though that's arguably a quality signifier.
Nominal value is in name only, IMO.
Which makes it not the value. I can sign my name on a piece of paper and say it's for sale for $5million (nominal value, right?) but it's value is nowhere near $5million, and noone will accidentally purchase it for $5million because they truly thought it was worth that.
nominal: existing or being something in name or form only (Merriam-Webster)
Nominal value of legal tender is in fact legally defensible.
Mind that the problem is actually the inverse of what you describe. It's not that the nominal value is greater than the intrinsic specie value which causes problems with coinage, it's where the monetary value is less than the commodity value of specie, in which case "bad money drives out good". I've already discussed that in detail.
One point worth making explicit is that the receiver of such an under-priced coin would be more than happy to receive it, it's the spender who has to weigh the loss in commodity value against the nominal transactional value, should their counterparty only agree to acknowledge the latter. This brings up the further point that in an exchange, transaction price (whether nominal or commodity) depends on the alternatives available to the parties. A spender without alternatives on price or obtaining desired goods/services might well spend a higher-commodity-valued coin at its nominal value. Should they be aware of that difference, they might well not be happy about the fact, but they'd be forced into the trade by circumstance.
There's no intrinsic reason balloon-framed housing has to be poorly insulated, and properly-insulated (and wrapped) balloon-framed construction is actually far better insulated than the "well-insulated" thick-walled structures based on stone, packed earth, brick, etc., which traditional half-timbered or masonry structures offer.
There is of course a large stock of extant housing which pre-dates best-standards insulation practices, though much of this can be improved dramatically at relatively low cost, especially by improving siding ("wrapping") and insulating attics. Thicker walls (nominal 2x6 rather than 2x4, or greater) can also be retrofit, either extending the exterior or interior wall dimension, though at considerably greater cost, and with trade-offs to either exterior or interior dimensions (lot size, environment, or reduced interior volume).
