While blowing, some of the fan's energy is spent on increasing the pressure inside your dishwasher, which increases the density of the air the fan blades move through, increasing drag on the fan blades causing them to move slower and create less airflow.

While blowing, you're also pushing moist air to the back of the dishwasher, and after that air reaches 100% relative humidity, it can't hold any more water and will not help dry your plates. Some of it will eventually escape around the sides, but some of the airflow your fan creates just circulates humid air around the inside of the dishwasher.

Turning your fan around solved both problems. It increased the volume of air flow, and decreased the relative humidity of the air flow.

A lot of the electricity probably came from burning natural gas at the power plant, and then some of that (~5%) gets lost in transmission. If we assume the natural gas plant is 60% efficient at turning gas into electricity, then an electric heating element in a hot water tank at your house would be about 55% efficient.

A typical gas furnace is about 80% efficient at turning gas into hot fluid, and a good one can reach 95% efficiency.

Depending on the fuel mix of your local grid, there's a good chance that burning natural gas at home will result in less pollution than using electric resistance heaters, either for heating water or the air inside your home during winter. Places like Washington state that generate most of their electricity from hydroelectric power plants will be exceptions.

However, heat pumps can be higher than 100% efficiency. They don't use electricity to generate heat, they just move heat from one place to another. You'll produce fewer emissions overall by using an HVAC heat pump to heat your house, and a heat pump water tank for hot water. Even if you live in a place like Canada, you can reduce emissions by installing a dual-fuel system that will use electricity to run the heat pump weather permitting, and fall back to using gas when the outdoor temperature goes too far negative.

Using heat pumps to move heat from outside, to inside your house, to inside your hot water tank is more efficient than using gas to heat your home and water, even when the electricity to run the heat pump is generated by burning natural gas.

Back in the day it was the best at what it did, but there's less demand these days for that kind of old fashioned search.

Its still better than the competition at finding the URL of a corporate or government entity. Its still helpful for searching other websites for particular content - for example, the wikis for some games have an obtuse layout and unhelpful search function, and google can be the best way to find a particular page in that wiki.

Before ChatGPT existed, and before the enshitifaction of Reddit reached the critical level its at today, google searching site:reddit.com was pretty good at finding organic human conversations that provide actual answers to your questions.

Today however, ChatGPT is better at providing useful answers to whatever questions you may have. And Bing is better at image search.

over charging customers and under paying employees

That's the crux of the issue.

Who's going to buy it for a high price, if there is no demand for office space, because workers are all remote?

The market didn't need regulations to maintain its freeness back then because the vast majority of transactions were made with small businesses. The limited technological capabilities in transport and communication also decreased the need for government regulation by decreasing the ability of the largest concentrations of capital to succeed at implementing global anti-competitive strategies.

To achieve the same degree of market freedom today, in the era of omni-national mega-corporations wielding monopoly influence, requires utilizing levers of power outside of the market those mega-corps dominate. The intervention of democratic governments to enforce anti-monopoly laws and prohibit other kinds of anti-competitive behavior is a necessary component of any plan to transform today's marketplace into one that looks more similar to the market of Adam Smith's day.

It is though - this is what capitalism invariably becomes. Musky Twitter is a symptom of late stage capitalism. This is why so many people say capitalism is bad and doesn't work as advertised.

The golden age of classical liberalism, when capitalism actually worked, the 1700-1800's, more closely resembles what we would today call market socialism.

Once the agglomerations of capital became large enough to impose irresistible anti-competitive force, the days of capitalism's beneficial functionality ended. They say "the freer the market the freer the people", but an unregulated market isn't free - it invariably trends toward monopoly and irrationally assigned concentrations of wealth and power, eg Musk, Bezos, DuPont, Sackler, etc...

Capitalism supports, rather than resists, the anti-competitive influence of capital. A truly free market requires the intervention of powers other than capital - eg, democratic governance imposing something akin to Market Socialism against the wishes of those anti-competitive agglomerations of capital.
