When I say mothers are not always available that was a polite way of saying mothers sometimes die during childbirth. A gross number in America but childbirth is dangerous even in the best circumstances. It is a leading cause of death among

If you need baby formula you can’t avoid baby formula. Not all mothers can or want to breast feed. Mothers are not always available when babies need to be fed. Any supply chain for secondary breast milk is going to have similar contaminatio

Most goods and services don’t fluctuate minute to minute despite input prices varying minute to minute. If I go to a car dealer the price of the car doesn’t change while I am there even when the real time price of commodity inputs are movin

This is in fact how regulated utilities work for fixed rate customers (simplified). The utility charges a customer a rate of x for some period. If the cost during that period is below x the utility may have to lower the price in the next pe

Renewables do make electricity cheaper. Here is a highly simplified version of how rates are set: Fixed price = (unit cost + a profit margin) * number of units The fixed price is set for a period of time based on historical and forecasted

The research on the oral transmission of epic poems should meaningfully affect how you read/think about the Iliad and The Odyssey. Further, the absence of knowledge about Homer himself is useful information (you might even try to use t

This would make it impossible to share definitions (even when we both think all the same things are bread).

What isn’t fully thought out? The categories in the report are weather related, equipment failure, and fuel supply issues. These are considered in the report mutually exclusive. But they aren’t, it is just a useful categorization. You are s

Page 16 is quite clear: the vast majority of missing generation capacity was natural gas. The lost wind capacity was comparable to lost coal capacity. Whether the cause is categorized as equipment failure, weather, or fuel availability, the

That was only part of the Texas issue. Many Nat Gas plants were also offline. For nearly the whole time Nat Gas outages were 2x wind outages according to ERCOT. Here is their own report: https://www.ercot.com/files/docs

I misspoke. The K&T I had in my house had gaps in the loom because it failed. You also can’t insulate around it.

Lead remediation isn’t just sanding and covering with paint is not always a good idea. First windows and doors are painted friction surfaces which create lead dust. Second, painting over it assumes the bond between the substrate and the lea

The major thing that is unaddressed is the inertia of the extant built environment. We know that lead paint is bad for people, especially kids, but we haven’t remediated it in much of the pre-1976 housing stock. Why? It is expensive and the

Anecdote on the estimates. We bought a house for X and renovated it. The day before we listed it both Zillow and Redfin estimate had an estimate around the purchase price X. When we listed it for 2X, both companies changed their estimate to

As long as gas is used to produce electricity the energy delivery systems are not independent. In a home the two systems generally serve different purposes so I am not sure the value of having both is as high as you suggest. My gas furnace&

In early 2014 numerous pipes were shut down in the eastern US because supply was not enough to meet demand due to a polar vortex. Compressor stations break down, suppliers fail to deliver gas, mercaptan might not be available, control syste

Tesla doesn’t buy the octovalve from other suppliers but it uses the same module in every model they make.

Gas is also supplied by a set of pipelines. There isn’t a free lunch.

None of the explanations below are correct. It is warmer but most people don’t have electric heat (resistive or heat pump). Fewer people are home but they are at work and commercial and industrial uses are the largest use. Electricity use p

Who is the we? Different countries, states, and grid-operators have different policies. Grid-scale renewables in the US are not ‘take it any time I have it’ to the grid, they are generally required to be able to dispatch down. This means wh

The goal of adding solar isn’t to use less electricity or less energy per person. Solar electricity is cheap and stable because it doesn’t have a volatile, margin-sensitive commodity as an input (as opposed to oil, ng, coal). Specifically,

Imagine I have a load that varies between 10kW +\- 50% and an intermittent generator that outputs 1kW at maximum and sometimes zero. I don’t have any need for storage so why would I have to calculate any storage cost? This is basically the

That just isn’t true. Solar is among the cheapest per watt to build [0] and produces very cheap electricity [1] even if you remove subsidies. It isn’t a perfect technology but that is beside the point. Further, every other technology for pr

Maybe you can see changes but you can’t see the actual number. The people being polled and the pollsters themselves are incentivized to lie. They poisoned Navalny and then killed the doctor who treated him. If I am Russian living in Russia

Do you trust opinion polls of people subject to autocratic regimes? Do you trust the people doing the polling? If you lived in Russia and you got a call from a stranger asking if you support Navalny would you say yes? Seems obvious these is

These are for college, not high school. Private high school costs have gone up as fast or faster than college. This cannot be explained by the availability of federal loans.
