[..]sophisticated transfer switch with power monitoring[..]

Those break. Way more than they should. Often with interesting results that aren't just "power went off".

And you fundamentally can't make them redundant. You can have two of them on completely separate feeds of course, feeding into different power supplies on the servers. That sometimes helps, except when the overvoltage is sufficiently great to get through the protections of the power supply.

Please provide a link where I can buy a cheap 16TB tape drive. Even an LTO-7 is too small, so you have to play tape jockey, and the tapes cost about the same per TB as the disks. And that is after you find the extortionate amount for the drive.

Tape possibly makes sense if you can afford an autoloader. HP has a LTO-6 autoloader for $4,239.99 that will do 20TB really (50TB fake). It will, however, only backup/restore 560GB per hour. Let us hope you have a slowly changing dataset and incremental backups are your thing...

The reason why 2.5" became popularin servers is that servers usually care about IOPS ratherthan capacity. For capacity, they tend to access storage somewhere else.

If you open a 15K 3.5" drive from back when those seemed like a good idea, you'll discover that it consists of a less-than 2.5" drive and a bunch of eitherair or metal around it. No one managed to make an ACTUAL 3.5" 15K drive, the forces involved are just too great.

There also wouldn't be any market for it, as practically all potential customers would be short-stroking it to lower worst-case latency.

Manufacturers took advantage of loopholes and leeway in the regulations, but as far as I am aware (and I have been following dieselgate closely), no cases have been found where manufacturers produced falsified documents.

They falsely stated emissions that they could not in fact do in practice. The cars were registered and license plates issued under false pretences.

If the correct values had been provided, the cars would not have been street legal. Getting them registered anyway is fraud.

This wouldn't have been a problem if you hadn't provided falsified documents to the authorities when getting your diesel car registered. Now obviously you didn't KNOW you did so, since you in turn got defrauded by the car manufacturer. That isn't my problem though, I just need you to stop poisoning me.

Since the legal system has proven to be completely incapable of dealing with dieselgate, we are forced to turn to local politicians to help. Sucks to be you.

Either way, hybrid petrol cars provide the benefits of diesel without the downsides. Manufacturers have made it entirely clear that they are unable to produce small diesel engines (less than 3L, perhaps) with acceptable levels of NOx output. Hence banning them is the only reasonable option.


A Coal-Fired Power Plant In India Is Turning Carbon Dioxide Into Baking Soda ( 197

schwit1 quotes a report from MIT Technology Review: In the southern Indian city of Tuticorin, locals are unlikely to suffer from a poorly risen cake. That's because a coal-fired thermal power station in the area captures carbon dioxide and turns it into baking soda. Carbon capture schemes are nothing new. Typically, they use a solvent, such as amine, to catch carbon dioxide and prevent it from escaping into the atmosphere. From there, the CO2 can either be stored away or used. But the Guardian reports that a system installed in the Tuticorin plant uses a new proprietary solvent developed by the company Carbon Clean Solutions. The solvent is reportedly just slightly more efficient than those used conventionally, requiring a little less energy and smaller apparatus to run. The collected CO2 is used to create baking soda, and it claims that as much as 66,000 tons of the gas could be captured at the plant each year. Its operators say that the marginal gain in efficiency is just enough to make it feasible to run the plant without a subsidy. In fact, it's claimed to be the first example of an unsubsidized industrial plant capturing CO2 for use. schwit1 notes: "A 'climate change' project that doesn't involve taxpayer dollars? Is that even allowed?"

Nuclear generation is pretty much constant - it gains no benefit from efficient storage - the plants don't store power anyway.

That is the problem with nuclear. Load is far from constant. Nuclear is reliant on peaking plants babysitting it, just like wind and solar does.

The main difference is that solar production actually correlates pretty well with load in large parts of the world, and that renewables are dropping drastically in price so you can afford to over-build and throw power away. This is unfortunately not true for nuclear.

It doesn't work particularly well on Mars. No one has ever done proper nuclear in space.

The only nuclear energy in space has been RTG's. Feel free to build as many RTG's as you want on Earth. They are wonderfully safe devices (unless someone deliberately takes them apart). Just don't expect electricity from RTG's to be cheap or plentiful, because it won't be.

And it strikes me that for scientists who think about and investigate this stuff every day, predicting 'bootstrapped' methane emissions as at least a potential problem should have been a no-brainer.

They probably had no data or solid modelling supporting it. Most scientists are wary about publishing alarmist articles, unless they are very sure.

This is also a reason why the sea level rise estimates were known to be way below what was likely to actually happen, for a long time. They are betternow that models have improved.
