The steam turbine may be stuck at 49%, but you can do multi-stage and heat-recovery from the smoke, or you can decide to use "waste" heat for district heating.
They aren' planning on retrofitting it on vintage cars like yours. I should think the larger problem for you will be getting out and hand cranking your engine at the stop lights. I mean, pre-heating the glow plugs, what exactly are you driving?
If you can grow corn, you can grow switchgrass or willow. Of course that won't fuel your car either until we switch to electric cars, but it will replace coal and that is more important at the moment anyway. Oil will run out on its own, coal needs to be replaced by something cheaper.
Sure, corn ethanol is over-unity. However, over-unity doesn't count. We don't have enough land to use for corn at a ratio of 1.56. Why not grow switchgrass or willow instead? Or just burn the corn without processing, you'll probably get a ratio close to 3 that way.
The problem is that you are not paying the actual costs of that energy. You get to spew oxides and particles into my air without compensating me. If your consumption was taxed so you paid the external costs, I would say consume all you want, but right now I'm paying for your fuel and I don't like that.
The solution to inner-city traffic jams is rather easy: Just make roads narrower or close them to traffic. If there is an uproar about not being able to get somewhere in particular, improve public transport or bicycle paths to that spot. Eventually people will learn, and the traffic jams will either go away or consist of way fewer cars, and people will get around quicker on average.
The difficult bit is selling this solution to the public who at first see more traffic jams and lots of spending on public transport which no one uses. Not a good election platform.
We have easily enough resources to extend American quality of life to 6 billion people. It isn't the planet setting the limit, it is ourselves and our technology. Our primary problem right now is sufficient energy, but the Sun beams way more energy to us than we need, even if you only count desert regions. Nuclear energy would also solve the problem.
The problem with preaching about overpopulation is that it is generally done by us in the first world saying that the third world should solve our problems with inefficient production by having fewer children. It isn't THEM who are the problem, it is US. Once they start generating enough pollution that it's a problem for everybody, we can start blaming them too. China has recently reached that stage.
Why grow sugar in the North when the tropics can easily supply everywhere? If you want biomass, grow switchgrass or willow, if you want animal feed grow corn... Sugar beets are a lousy crop which only exists because of trade barriers and subsidies.
That is a minor engineering problem though. We got through the switch to unleaded, from a technical viewpoint we can relatively easily switch to more than 50% ethanol. We just do not have an efficient way to produce that much ethanol, apart from sugar cane.
Corn is useful for animal feed. It is a reasonably efficient plant if you measure yield/acre (and you use the whole plant, not just the cobs). Burning corn as a substitute for coal is not out of the question, although switchgrass or willow are more obvious candidates.
Sugar beets are another lousy way to make sugar. They do not grow in high-solar areas, they capture solar energy less efficiently, and their sugar content is lower than sugar cane.
Ethanol is a relatively safe octane booster. As long as temperatures are not too high, it is a great idea to add some ethanol to the fuel, even if you lose a little bit of range.
With current production methods you really should not try to use it for its energy content though, except perhaps if you have access to a lot of area where you can grow sugar cane. Wasting corn on making ethanol should not be encouraged.
Electricity production is a market with large fixed costs and generally low marginal costs. A free market will force the price close to the marginal cost, leaving no money for fixed costs. Eventually some less efficient producers are forced off the market, creating a situation with insufficient production, increasing prices and letting the other producers make some money that they can use for maintenance. During that period, demand exceeds supply.
You will have a situation where most of the time electricity is perhaps $0.05 per kWh but once in a while it's $5 per kWh. Combine that with contracts locking most consumers to a fixed price and you get rolling blackouts.
The script was used during the design of the CPU, it didn't run at runtime. The results of the script was burned into silicon as a lookup table. Whether a lookup table is software or hardware or firmware is up for others to decide, but the original bug was in completely normal software running on a normal CPU.
...have you noticed that Canada isn't using this to promote itself as the "Hub to the Americas"? Fly to Canada first (East Coast from Europe, West Coast from Asia), then get a connecting flight to Central or South America and vice-versa? Wonder why that would be...
You'll pass through US airspace, which puts you at risk of an unscheduled landing. Instead you could go from London to Mexico City direct.
The only problem with exim configuration is that they're trying very hard to pretend that the acl part isn't programming. Traditional if then else would be a lot easier to read by everyone who can handle shell scripting, and if you can't handle shell scripting you aren't likely to handle an obscure language with side-effects based on boolean short-circuit evaluation.
You can get very far without touching the acl's, but those are what makes exim more capable than most other MTA's.
False DNA matches will happen. Not because of mathematical chance, but because it is extremely easy to contaminate DNA samples. I wish they would always send the samples from the crime scene to an entirely different lab from the samples from the suspected individual, for instance, but AFAIK it is often the same lab handling both. The same thing applies to samples from different crime scenes, where the lab could end up establishing links between unrelated crimes.
You often have a cryptographically secure and reasonably fast hash algorithm available in some library, no matter what you program for. It's easier to just pick that by default instead of spending a lot of energy on developing and debugging something which might not end up all that much faster or smaller in the end. Skein is in the region of 6 cycles per byte on modern Intel CPUs. That should be fast enough for almost all uses. SHA is slow on modern CPUs, but even that is often fast enough.

Then Lorenz and Mandelbrot appeared on the scene, and the whole premise of psychohistory went out the window.

Don't hold the rest of us back though.

Why would you want to grow sugar in places unsuitable for it? Freight is cheap.
I meant that fuel producers should add it, not random people. On re-reading I can see that I said practically the opposite. Sorry.
