Giant Microwave Turns Plastic Back to Oil 555
An anonymous reader writes "From the newscientist article: "Key to GRC's process is a machine that uses 1200 different frequencies within the microwave range, which act on specific hydrocarbon materials. As the material is zapped at the appropriate wavelength, part of the hydrocarbons that make up the plastic and rubber in the material are broken down into diesel oil and combustible gas.""

No, the reason why plastics are not very recyclable is that you cannot substitute one plastic for another. The previous method recycles polycarbonate from CDs only into polycarbonate. Polycarbonate cannot be used instead of polyethylene, polypropylene, polyvinyl chloride, etc. These other plastics have far more uses. So turning into fuel is a more general use to me.

The problem with current plastic recycling is that you reduce the length of the polymer molecules each time you recycle, reducing the quality of the plastic. So you can't turn PET bottles into PET bottles indefinitely; you have to turn them into lower-quality plastic items such as plastic speed bumps. After a couple of cycles, the plastic ends up in a landfill.
And that only applies to thermoplastics (which can be melted). Thermosets, which cannot be melted, are much more difficult to recycle, and are "downcycled" much farther in quality.
The beauty of the "giant microwave" process is that it turns plastic recycling into a truly cyclic process, instead of a delayed linear process. If you transform plastic back into its raw material, you can recycle it into plastic of equal or greater quality (upcycling). You keep it out of the landfill for much longer (not accounting for people who don't bother to recycle).

That sounds to me like a recipe for high inflation. After all, the only thing that causes inflation, is inflation: things get more expensive so people demand a pay rise, and then having to pay workers more makes things get more expensive.
Actually not. Money, is a commodity.
It acts just like any other commodity. If there's too much coffee, the value decreases. Money works in exactly the same way. Inflation can only occur if there's too much money in the economy, the value of the individual dollar/pound/euro decreases and everything else appears to increase in cost. All that's happening is that the currency is devaluing, which you then see on the currency markets as well.
The dirty little (non) secret of our current monetary system is two fold. First, "the national debt" and second "fractional reserve banking".
The first point is that the government and central bankers create money from nothing and create a national IOU to balance it. The government borrows money from the bankers and they write down this debt and demand interest on it. The money has been borrowed into existence. This money is then paid to government employees, contractors, suppliers etc where it enters the economy.
The second stage of this is the fractional reserve banking system. This is perhaps the biggest scam ever created. The fractional reserve banking system allows commercial banks to loan out to people more money than they have in reserve. Hence "fractional reserve" Typically they can loan out up to 20 times more than they have in deposits. That is they only have to have on hand about 5% on average of what they are allowed to loan out.
So this money comes from the government national debt, into the economy, lands in the banks deposit accounts and is then multiplied about 19 times as loans. 95% + 95% of that 95% and so on till it reaches 0. It's a recipe for creating both massive debt and massive inflation.
Which the central banks and government attempt to control using the base interest rates. Essentially what it does is divide society into the creditors and the debtors. Every dollar that someone owns is one dollar's worth of debt, owed by someone else. There are other implications also with constantly and repeatedly paying 5% interest on money.
1. The bankers will ultimately be the sole and inevitable owners of everything. They set the rules of the game years ago.
2. Everyone has to work an extra 5% harder each year for their cash, because they have to try to pay this debt. This has implications for everyone and everything. All businesses, taxpayers must constantly expand their efforts by that 5% every year to service this interest. Think about it. This is an exponential increase. 100%, 105%, 110¼%, 115¾%, 121½% and we have to try to keep up. It explains why capitalism has become so rapacious. The debts have to be serviced and to even pretend to do so requires an exponential increase in the economy.
3. The debt can never actually be paid. There isn't enough money in existence to pay of the debt, ever. Because of the interest on the initial creation of the money. You borrow $100 into existence but owe $105 at the end of the year, the extra $5 doesn't actually exist, it was never created, so you borrow some more. And so we divide into the people who have managed to pay the debt and people who are saddled with mounting levels which are literally impossible to pay.
It didn't used to be this way. A trade used to mean that two people exchanged something of value. A chicken for a duck. Both of them benefitted. Even when money came along, it still meant that both parties benefitted, they were exchanging items they valued more, a chicken for a dollar, it wasn't required for someone somewhere to lose out. That all changed during the last century. Our money became debt based. Every dollar/pound/euro/yen/yuan required a debt, paying interest to the bankers, interest on money they created from nothing.

Huh? The debt is no different than my personal debt. I have some income. I have some expenses. I have some debt. I pay more on my debt than the interest, and the debt goes down. Eventually, it becomes zero
As individuals we can theoretically pay down our own debt faster than it accumulates by reigning in our spending, or working harder or whatever. But this can't happen on the macro-scale, if I start paying my debt faster, it just means someone else is falling behind faster (indirectly because they are paying me more, or suffering from me not buying as much).
There simply isn't enough money in the system to pay everyone's debt down. Unless we print more, and then lend it to people... which is exactly what we do. Except that borrowing more money to pay down the debt doesn't really get us anywhere.
Its equivalent to paying your Mastercard with your Visa.
Intuitively eventually this catches up to you, and it looks like this is finally starting to happen. They thought as long as the population grows, and technology advanced, that the total productivity of the nation would keep up with the currency debt spiral, and the 'balance' could be held indefinately.
Deflation has been deemed worse than inflation. Deflation is harder to manage than inflation. So a "small" inflation has been built-in to our economy to ensure stability of the economy. People much smarter than you determined that this is an acceptable trade off.
They knew it was unstable, but they thought they could control it. I can't say for certain that it absolutely can't be controlled, but its becoming clear that they, at the very least, lacked the discipline or ability to control it.
Inflation is rising, despite their best efforts to keep it low, and they're lying about it. They are changing the rules, and redefining things to hide the true inflation rate. The use of hedonics for example.
If you bought a computer 3 years ago for $1000, and then replace it with one that today also costs $1000, but is twice as fast. They count it as a $2000 dollar computer (because its 'twice as good' as the old one) and inflation shows that the price of computers today is half what it was 3 years ago, despite the fact that we're still paying the same amount.
Of course, when the price actually goes up, they substitute an inferior product to keep inflation numbers looking low. Suppose you bought a desk for $200 dollars several years ago and it was made of, oh say, actual wood. And then you try to buy that same furniture today, you'd find might it would cost $1000 perhaps, you know, due to the inflation of the price of wood... but you can get a piece-o-crap desk at walmart made of plastic and particle board for $200 bucks -- well then we'll just substitute for that and inflation shows a 0% change. Desks are still $200 hurrah!
And when something is really ugly, like the recent fuel price hikes... well how are we going to fix for that? Its not like we can substitute a cheaper product in? How about we just not count fuel anymore? Ok! So, now inflation is reported excluding energy. (And food is excluded to for that matter.)
So lets see... inflation is supposed to be a broad measure that tells us essentially how much more money we need this year over last year in order to maintain the same standard of living? Yet it excludes the cost of fuel and energy. It requires that I buy inferior products. And even though my cellphone costs the same as the last two I've bought I'm supposed to think I've massively splurged on it because it now has a camera, and picture caller id.
So what exactly does 'inflation' mean NOW? Its just a meaningless number so detached from reality that its useless, except that people still find it pschologically reassuring to hear that inflation is

I've heard anecdotally that in Japan, there are people who basically go through trash at transfer stations, and will hunt down (based on personally identifying information in the trash) those folks who don't sort their recyclables out and reprimand/embarrass them -- short of something vaguely creepy like that (and in the U.S., social ostracism and humiliation aren't going to work as punishments), I'm not sure any consumer-sorting programs are going to work.
Without draconian enforcement, I think the sorting has to be -- or at least has to be backed up by sorting -- done at the transfer station or dump.
From a different perspective, sorting garbage based on predetermined criteria seems to be like something that, once you get over the initial investment in the system that does it, is probably better done by one giant machine that sorts the garbage for 100,000 people, than each of those 100,000 people having to take a few minutes a day to think about it. From a purely economic perspective, the opportunity cost of everyone's time probably justifies an automatic sorter, and when you factor in the recovered value from the recyclables [1] and the possible "dump mining" aspects that it creates later, I'd think it would be a good investment.

One of the great and wonderful things about English is that spelling reflects quite accurately the history of the word. Sure, there are some pronunciation ambiguities that are a little difficult to learn, but even ESL learners get over that hill remarkably quickly.
But with English -- unlike almost any other language -- you can look at a word and immediately know that its roots are in Greek, or Latin, or French, or Celtic, or whether it's a modern loan word. This has massive benefits for advanced literacy, as it means you actually know more words than you think you do, and can quite accurately guess at the meaning of new words you encounter -- which is of far greater utility than simply knowing how to say the word. Get the sound wrong and people will correct you almost immediately, so what's the problem?
In other languages, once a word has been imported, its roots are lost, and with that the connection to the linguistic system from which it came, and its connection to other similarly-sourced words.
So, regular spelling: great for primary school kids; not so great for everyone else who wants to use language at a more advanced level, for things like communication and literature.

Air is an even worse conductor, and the potential difference across the air between a piece of electrically-charged metal and the earthed oven wall might well be significant.

Okay, a publication calling itself scientific is not going to publish figures in non-SI units. I appreciate the effort of conversion, but it's not much better to publish figures in "base 0.454", as it were.

What if you want to express the total yield per unit of ground-up tyres? Use a unit amount or a power of 10 amount of tyres and calculate the rest from that:
For every 10 kilograms of ground-up tyres, the Hawk-10 produces 5 litres of diesel oil, 1.6 cubic metres of combustible gas, 1.1 kg of steel, and 3.7 kg of carbon black.
