AC/DC converter losses are on the order of 10%. Negligible, and don’t change the point. Your pedantry is noted and ignored.

Every single Chinese EV manufacturer wants to go make sales abroad because the price war in China makes profits barely attainable, but government policy and subsidies keep sales within the country.
The open secret is that China’s EV subsidies are designed to keep sales within the country, because otherwise Chinese EV companies could make obscenely higher margins selling overseas.
The BYD Seagull ($9700 in China) is being sold as the BYD Dolphin Mini in Mexico… For $21000.
The BYD Seal U (€19400 in China) is being sold in Germany for €41990.
Sanders could’ve won against Trump in 2016 and he could’ve won against in 2020. Yet, here we are in 2024…
Lai is a short-sighted idiot that would rather be dependent on external seaborne LNG imports than maintain any degree of energy independence with nuclear.
I don’t think I need to say anything about how bad natural gas is.
How much internal migration between Crimea and other regions has there been? The population of Crima has hovered around 2 million for decades.
Dividing America by building infrastructure instead of dumping trillions of dollars into the next military superproject.
I shouldn’t need to say that not only natural gas bad, but oil also bad
I’m cautiously optimistic that the burger empire will embrace HSR like the rest of the advanced world. America’s competition is no longer the Soviet Union, but China.
Heat is actually surprisingly easy to moderate with green spaces, water, shade, and wind.
Unfortunately, roads, roofs, and buildings fuck that all up.
Plant trees along every road. Line every building roof with greenery. Water that greenery, and centrally control how it’s watered to create temperature/humidity differentials and thus wind throughout the entire city.
Can you ban people for spurious reports too thx
The real answer is that most roads are a transient solution as transit gets built out. They should form an auxiliary network, not the backbone of a country’s transportation.
In this case Russia shot down everything and there were casualties.
Yay I love little explosive pellets
It’s not. Americans just can’t live without AC.
Building, or built? Either way, maybe these companies will come out with a better design than Tokamak, but until then they’re literally just research ventures because the vast majority of investment at actually scaling fusion is happening for Tokamak tractors.
That’s from a lack of vision rather than anything else. Google is IIRC
I don’t think you understand thermodynamics.
ACs are heat pumps that use temperature differentials to move heat from one side to another. There are inherent losses there (e.g., moving 1000kJ of heat out of a room might take 500kJ, for 200% efficiency). That excess 500kJ is dumped outside into the world along with the 1000kJvof heat, creating a local heat island effect. That’s why ACs consume electricity, and that’s where the energy goes.
The radiator behind the freezer isn’t mega hot because of advances in insulation that limit the amount of heat that needs to be moved and advances in efficiency when operating in specific temperature regimes. A modern fridge consumes 400kWh a year, which averages out to 1.1kWh/day, or 45W continuous draw. That’s about the same as a laptop charger. But, well, obviously your house is much larger than your fridge. A fridge might average 400L in volume, but your house averages more like 600000L (1500x more).
If you could move heat around without incurring losses, you could use that to construct a perpetual motion machine. Conservation of energy is a thing and entropy always increases.
If we really cared about the warming component of climate change, we would stop funding natural gas and dump all the money we would have spent on natural gas infrastructure on renewables. We would roll back the ship fuel sulfur ban (which has a cooling effect) and rely on corrective measures for pollution problems in exchange for preventative measures for warming problems.
Because of methane leakage and other factors, natural gas is only a net-positive effect over coal in terms of greenhouse effect somewhere between 20 to 100 years down the line (imo reasonable estimates put this at around 40-50 years). Until then, natural gas has a more significant warming effect than coal because of obscenely high rates of methane leakage during transmission and distribution (which are underreported by relevant agencies to the order of 2-5x).
There is no one solution to climate change, but the question now is whether we care about it as the only problem or just one of a myriad of problems caused by human activity.
You didn’t have to inject your pedantry everywhere either over 10% losses, and yet here we are.
