Mnuchin said:What a jerk. The idiocy stinks.
Is she the chief economist, or who is she? I’m confused. It’s a joke. After she goes and studies economics in college she can come back and explain that to us.
Not knowing much about capacitors (yeah, less than even that), I had this idea the moment after I heard that Tesla bought Maxwell - that one could load up a (future 1,000 km range) EV's capacitors really fast (like in 5 minutes - "megacharge"!), then get the car back on the road, and have the capacitors then, at near-optimum rates, charge up the battery.Ir's an impractical idea for several reasons.
Probably anybody who actually knows something about capacitors would know my idea is bunk. Musk said in that long interview that he's hyper-rational - he compares his ideas with known physics before proceeding. I just don't know the physics.
As of 2013 commercial specific energies range from around 0.5 to 15 Wh/kg. For comparison, an aluminum electrolytic capacitor stores typically 0.01 to 0.3 Wh/kg, while a conventional lead-acid battery stores typically 30 to 40 Wh/kg and modern lithium-ion batteries 100 to 265 Wh/kg. Supercapacitors can therefore store 10 to 100 times more energy than electrolytic capacitors, but only one tenth as much as batteries.So for energy storage where weight is a consideration supercapacitors are not very useful. However in applications where a high power is desired and weight is less of an issue supercapacitors have the physical ability to be useful (not sure about cost).
Maxwell Technologies, an American supercapacitor-maker, claimed that more than 20,000 hybrid buses use the devices to increase acceleration, particularly in China. Guangzhou, In 2014 China began using trams powered with supercapacitors that are recharged in 30 seconds by a device positioned between the rails, storing power to run the tram for up to 4 km — more than enough to reach the next stop, where the cycle can be repeated.For an E-Semi I don't think supercapacitors can be very useful, as the weight of the battery is a very important consideration (the limiting factor for increasing range). However for buses and trams that have short routes and require rapid charging, supercapacitors could be quite useful.
So, bring it on!For the record, I strongly disagree with your post.
This energy storage solution is quite clever!This solution (quite innovative) was posted on the forum in the past. The main worry which seems unaddressed is the risk of earthquakes. Otherwise, great idea. Once the blocks are up kinetic energy is preserved for a very long time.

Oren, what do you think of the definition of a BOE as the unit of time, during summer, when surface air temperature north of 80 shoots up beyond normal summer variability? I think that will be a climatically momentous occasion. There will be much less than 1 million km2 remaining when that happens, and it will likely happen in August.Yes, that is when the climatic shit his the fan IMHO. But when? Hard to guess.
At the end of the 90s, it was for me the 'bitches', 'hoes', 'gangsta rap', vocoders etc. that ended my connection with and interest in modern music. Glorification of violence and bad behaviour, toxic masculinity. The end of love; the end of trust, kindness and intimacy.I sympathize as I really dislike that type of music/violence. But there is still trust, kindness and intimacy in music even today. There's also sadness and vulnerability. You normally have to look hard for it, but sometimes such music even becomes popular by some miracle.
I stopped listening to popular hits, made my own playlists and later started my search for older music. Morality in music sunk to the bottom. What a stark contrast with the 80s and 70s.
If we are really serious about EV, every second parking space, paid or free, needs a 100kw, minimum, charger.I expect the number of chargers to adapt itself to the number of EVs, perhaps with some delay.
This is a major and popular misconceptionVery much not true. When you overfish the oceans leading to much lower fish output later, you borrow/steal from the future. When you deforest the Amazon for cattle and soy farming, leading to a much smaller carbon sink later, you borrow/steal from the future. When you overfarm leading to topsoil loss and poisoning of the ground with chemicals, leading to lower farming output later, you borrow/steal from the future. When you drain aquifers at much higher rates than their natural refill rates, leading to much lower water output later, you borrow/steal from the future. There are many other examples, too many to list unfortunately.
1) Real goods can not be borrowed from the future only nominal assets. Borrowing can temporarily push up the nominal price of stocks, housing, etc but won't change the amount of real goods available
3) Forecasting the end of the world is always a very attractive psychological position as it proves me that I am cleverer than everybody else and when they realize their doom I will be standing there, telling everyone: "I told you so"I am not a psychologist but it seems from reading this forum that "debunking" dire long-term forecasts using a variety of techniques is a very attractive psychological proposition for some members.
I don't think civilisation can collapse now because first the globalized infrastructure (finance, logistics, production, transport, energy) has to be severely damaged. A breakdown of 2 of those 5 will be enough I expect. Globalized infrastructure is a manifold of complex interdependend interconnected systems and I expect that when a tipping point is crossed through breakdowns, it will be a fast global crash. 'Just In Time delivery' cannot go on -> no deliveries.Yes, yes and yes.
...
Can the finance and energy infrastructure be 'sandboxed'? I don't think so because the whole system needs to be re-engineered and there will be no time for that. Missing essential resources and parts will stop almost all production. There is no resilience in our current systems and no self sufficiency. Most rich countries can't even produce their own food. Prices will skyrocket.
...
Some richer countries will be able to temporarily soften the blows and continue but not for long.
- human population: this is absolutely true, there are simply too many humans for this planet, but I do not think that any of you would have an IMMEDIATE solutionEl cid, on the contrary, the immediate solution is to reduce childbirth to one per woman, this would reduce global population in 2050 (which I estimate will be the crisis point) by about 2.5 billion down from the expected 10 billion.
Since we had more than that before FF and the Americas were not fully settled, that seems reasonable.Bear in mind those 1 billion people back in 1800 had much lower levels of resource consumption per capita, resources were more abundant, and the global environment with much less cumulative pollution.
The world's population is growing rapidly, and by 2100 will exceed 10 billion.World population is extrapolated/forecasted to reach 10 billion by 2050 unfortunately. So the issues considered in this thread will be larger and sooner.
As a result, the shortage of drinking water is increasing.
That would be the Qattara depression.QuoteYou can try to fill the deep basins with the ocean to stop the growth of the ocean. There is a project to fill the Dead Sea.I also heard one to fill a depression in North Africa. I forget the name, but I think it started with 'Q'.
