That takes the low score for me as the stupidest thing I ever heard anybody say. Not only have electronic devices transformed the world, they have had more impact than virtually anything else mankind has done, with the possible exceptions of Agriculture and powering a technological civilization with FF's.

That both of those larger inventions of mankind are also the prime reasons that the human race has destroyed the ecosystem, is beside the point.

Now note that you were able to make that incredibly stupid comment because of the efforts of me and many other EE's. In the not so recent past, you would have labored mightily to write or type a letter to a newspaper, and the editor would have shaken his head in wonder as he wadded up and then consigned your ignorant comment to the circular file.

I encourage you to keep going, under every username on every forum you frequent. The scale of intelligence must have a point of origin, after all.

There were a couple of things I want to point out to you as well. California was and is a good place to find a good paying job, and Silicon Valley is the best part of the state. I earned a good (not even unusual) white collar income that eventually reached the low six figures the last few years of my career, and my small house is worth 8X what I paid for it in 1986. How do those figures compare to wherever you call home?

That many people here in California are batsh!t crazy I will not dispute. That is why I am moving away after retiring. I mostly like the place - there are no equals to the Sierra Nevada Mountains when it comes to camping - but this place has two huge infestations of Democrats in the SF Bay Area and the LA Basin, and those folks are simply incapable of rational thoughts, or of keeping their thieving hands off of other people's money.

Which obviously explains why the world has abandoned hydrocarbons and runs primarily on alternative energy sources.

Might want to rethink some of those assumption. Just saying: even while one can try to defend those assumptions one still has to justify them to the fact the overwhelming amount of energy consumed on the planet is from fossil fuels. If those assumptions have failed for many decades and continue to appear invalid today (especially in light of decreased oil prices, low coal prices and an expanding global market for NG) when will they become impactful factors?

Actually I'm almost certain that that disaster-waiting-to-happen called California will jump the tracks by 2018. The upcoming 'California Crisis' (the economic reality that their civil infrastructure will have to get far more dense while tripling their population to 120 million (it was 92000 in 1850) to "pay" for the "new" "prosperity") will be the final nail in the coffin for renewables making way for an even more "greener" (useless) "solution" called fission reactors. Considering the "educated" phd dummies in Germany desperately want to be just-like-California, it will be ironic and highly amusing. The unbelievable growth Eulenspiegel is banking on will be instantly crushed, another speculative disaster much like ThyssenKrupps Brazillian Adventure Gone Bad.

All the useless paper engineers with their useless paper nuclear reactor designs (useless cad models and useless software code) will jump up and down with excitement for 20 minutes only to be completely ignored as the procurement officers that is California outsource all electrical generation to China for the mere price of sovereignty.

This is what defines progress since the arrival of the chips: 10x more people, 1/10th the living space, and 10x more corruption.

[KaiserJeep]

As does California, so do the other 49 states - just a few years later.

You will get more respect around here if you lay off the sarcasm and concentrate more on the grammar. Your source of subject should ideally bear some resemblance to the thread topic.

You forgot to mention Germany's new construction of coal plants to replace the nukes - while talking about renewables.

I'm ready to write off Europe anyways. After lecturing the USA for years on race relations, they let hundreds of black refugees perish in the Mediterranean. They have conclusively shown themselves to be rac!st pr!cks.

About freaking time! Intermittent sources of power require massive storage capacity which is freaking expensive if you want a modern American lifestyle like 99% of the world population does.

“Fossil-free steel” plant planned for Sweden [depending, of course, on where the hydrogen itself comes from! ]

Process would use iron ore pellets; and hydrogen rather than coke or coal. Emissions would be water instead of CO2.

Peroxide is basically the perfect fuel.

1) It can be stored long term and does not require compression like H2 which also happens to leak at serious rates from any container.

2) Combustion of H2O2 does not produce NOx as does the burning of NH3. And CO2 from the combustion of CH4.

3) Fuel cells can use H2O2 as both the reducer and oxidizer and do not require a membrane.

4) Catalysts can be used to produce H2O2. The large energy penalty of electrolysis is avoided. There are are catalysts for producing H2 as well, but H2 has too many minuses as an energy carrier.

------------

5) This is not a joke: currently areas around heavy traffic can be partly O2 depleted thanks to combustion using gasoline and diesel. At 19.5% concentrations, O2 becomes biologically deficient for humans. H2O2 fuel cell combustion releases O2.

Except that hydrogen peroxide is rather difficult to manufacture. Hydrogen peroxide - Wikipedia describes two main methods.

Electrolysis of ammonium bisulfate. It makes ammonium peroxysulfate, when can then be hydrolyzed to ammonium bisulfate and H2O2.

Reduction and self-oxidation of anthraquinone. The reduction part is combination of anthraquinone with hydrogen using a palladium catalyst. Adding oxygen then oxidizes it, releasing H2O2.

Decomposing H2O2 releases a rather paltry amount of energy: 2.9 MJ/kg. Energy density - Wikipedia more than a good lithium-ion battery and less than a chemical explosive. It lists diesel fuel as having 48 MJ/kg and other hydrocarbon fuels as not much different, but correcting for its oxygen consumption gives 10.8 MJ/kg. I used
(CH2) + (3/2)*O2 -> CO2 + H2O

Carrying H2O2 along as an oxidizer means carrying a lot of extra weight without anything gained, since one can more easily get O2 for the surrounding air. The only exception is in outer space, where one has to take one's oxidizer along with one's fuel.

The production of H2O2 requires electrolysis, and it may be simpler to make hydrogen or ammonia from that process, and for hydrogen, do some Fischer-Tropsch reactions to get something that is easier to store.

Correct. In fact the Germans selected hydrogen peroxide as an oxidizer for the ME-163 Komet rocket plane, the fastest plane in the world (702mph) right up until Chuck Yeager flew the Bell X-1 through Mach 1:

The hydrogen peroxide oxidizer (called "T-Stoff") mixed with the blended methanol/hydrazine fuel (called "C-Stoff") in the rocket engine combustion chamber and spontaneously burned (hypergolic ignition). This was a very dangerous airplane that repeatedly exploded on the ground before launch or in the air when pierced by a single bullet from a bomber's machine gun.

However, it went 700mph when a front line piston engined airplane went 350mph when fully loaded with fuel and armaments. It also had a 30mm cannon, which could destroy another fighter with a single shot, or a large bomber with 4-5 rounds.

i - I'm referring to the implication that steel is being created without the use of ANY FOSSIL FUEL. Great if it reduces the total amount of ff used in the process of creating steel. But it still requires some utilization.

Interesting that a man with a reported net worth of $23.6 BILLION had to be induced with a $750 MILLION subsidy from the state to build his solar plant there. And now the state's politicians are wondering if they made a bad investment. At least Elon doesn't lay awake a night wondering the same thing. I guess that's how you become a billionaire. LOL.

"Inside Tesla's troubled New York solar factory" Reuters - Tesla Inc’s (TSLA.O) production of solar roof tiles has been delayed by assembly-line problems at its new publicly subsidized factory and difficulties producing a product that satisfies the aesthetic demands of CEO Elon Musk, eight former and current employees of both companies told Reuters.
