Comment Re:But what if the sun isn't shining? (Score 3, Interesting) 110

Baseload is one of those talking points which get repeated and repeated again, but no one actually enumerates the baseload. How much energy do we have to provide constantly at a minimum?

The Dutch Railways are now completely wind powered as of Jan 1 2017. Apparently they don't need baseload power plants.

The maximum signal-to-noise ratio you can get from a cassette tape is between 60 and 65 dB (depends on the type of tape, Fe, Cr, Ferrochrome, Metal). The CD offers 96 dB. A cassette tape is really, really band limited. Above 16 kHz, it won't record anything meaningful. Below 50 Hz the same. A tape has not enough band reserves to even record VHF radio while preserving quality.

No, he didn't. Compact Cassettes were invented in 1963 by the dutch company Philips, and in the 1970ies, they were everywhere. I was born in 1970, and as long as I remember, we had a cassette recorder at home. I also remember all the cassettes my father had in his box with his recordings, which were called something like "Songs 1975" or similar. We never had an 8-track though. My father just commented once during a movie where you could see someone putting a cassette into his car's stereo, that this was an 8-track, the first time I ever heard about it.

If you write generic code, it might be a worthwile consideration. Most of the code I write is one-off-code. There is exactly one use case, and I write some small program to solve it. The same implementation will never be needed anywhere else. I know the size of the load beforehand, and I do my test runs on the whole load, so I know the absolute runtimes, and I know they won't change in the future. Many of my programs are somewhat glorified awk/sed/perl magic to convert data I get from a source somewhere into a format I have to use somewhere else, and the data size remains about the same for the foreseeable future. Sometimes, the program runs exactly once as it it used to import data from an old system into a new one, and the old system gets decommissioned when the new system proves stable and works as expected.

So all warnings about the future and code reuse and upscaling are nice and dandy, but actually, I just ignore them.

On the contrary: People don't use air travel every day. 99% of all travel is not air travel.

You are messing two things up: deciding against air travel for a specific trip, and abolishing air travel altogether.You are trying to make the one be the same than the other. Many issues with air travel can be solved by simply having less air travel.

Once you are out of a job and can't pay for a gun and ammunition anymore, it's definitely you losing.

Coal is quite expensive and inflexible. It takes literally decades to open a coal mine, extract the coal and close it up again. And it is only feasible if there is either someone constantly requesting the coal, or if you have large storage capacities for unused coal, or if some governmental body pays subsidies for the time you can't sell the coal, and thus have to stop mining.

But one solution to air travel issues is not to use air travel. Air travel is just one piece of the whole solution to the problem of getting from A to B, and it's not even a necessary one, as most travel is not by air.

There is a whole bunch of offerings, which can be put together to achieve the A->B transfer, and you not using air travel is even a solution for some of the air travel issues of others. They get shorter waiting queues and more available seats for instance, if you are not there on the same flight.

China might not be building coal plants anymore in 10 years, when Solar becomes cheaper. If you really read the article, you will find out, that there still are regions in the world, where at current prices, Coal is cheaper than Solar.

And also for coal, someone has to pay for the land and subsidy. Coal doesn't fall from the sky (other than sunlight, which literally does so), it has to be mined, and beside the coal mines you need tracks or roads to transport the coal to the plants. So Coal is also a big consumer of land, especially if the coal is mined by surface mining, which is by far the cheapest option.

And it works wonders if 40 tons of steel at 40 mph are crashing in a christmas market. Right?

Exactly. .50 cal api rounds do nil in such a situation. But you can be pretty sure to hit innocent bystanders.

If this is your plan, then the next terrorist will not even need to steer the truck into groups of people. Your .50 round will do the work for him.

After you already hit something? What would you win by not hitting the brakes? People rear ending you still have their airbags and seatbelts and crumple zones, which will protect them from the worst. People in front of you don't. So breaking and getting some 40 ton heap of steel into stillstand as soon as possible once it is out of control (and because it hit something, there is enough proof to call it out of control) is in any case better than let it run to save the people driving to close behind it a few bucks by keeping their cars undamaged.
