Data Storage Problems

7 Replies Jonny Hankins

This week the New York Times published a long article about the problem of data storage, and I would like to summarize some of their findings. The article is available here in Saturday’s technology section.

The article is an attack at what the author sees as wasteful use of resources in data storage centres. There are now hundreds of thousands of these huge centres spread throughout the world, and the problem is they use an incredible amount of electricity. The servers have to be kept cool and they have to have spare capacity so that we can download whatever we want whenever we want.

Worldwide these centres use about 30 billion watts of electricity, and that is about 30 nuclear power plants worth of power. A single data center uses about the same amount as a small town, and the main criticism is the nature of the usage.

In the US 2% of all electricity used goes to these data centers, but the vast majority of this resource is wasted. Typically many servers are left to run 24 a day but never or rarely used (more than half in this study), and the average machine in operation uses less than 10% of its capacity. Servers are left running obsolete programs or in ‘comatose’ because nobody wants to risk a mistake and turn them off.

All of this means that any data center might use 30 times as much electricity as is needed to carry out the functions it performs.

All of these centres also have to have a back up in case of power failure, and so are surrounded by diesel generators and stacks of batteries, and many have been found in breach of environmental regulations and fined. The article gives details but the companies are names that we all know and use.

If you read the more than 300 comments however you will discover that a lot of people do not agree with the findings as reported. Many technicians argue that the companies cited are investing huge amounts of money into making the storage of data more efficient, and are constructing wind farms and using solar power in an attempt to cut costs and emissions. The article has its agenda and exploits it fully, but the problem is real.

I personally believe that we are witnessing the results of a digital culture change. We no longer have to store data on our machines, we can store it in some mythical cloud out there in the cyber-universe. This makes us think that it somehow exists without the need for a hard drive, but this is not true. As a result we keep things that we do not need. I have 500 e mails in my inbox, with attachments, photos that I will never again look at and other useless things, and they are all in storage somewhere.

Technology advances, storage gets cheaper and uses less space, but the amount of data created is growing at an incredible rate. My question is, can we do anything about it? Are we not the ones who should take some responsibility and think about the consequences of our actions. We think about not using paper to print emails but we don’t think about not sending them!

Has Geo-engineering Moved On?

Last year I wrote a series on this blog about the environment entitled ‘Can We Improve the Health of the Planet?’ Read all of the posts and report on the series here through the Bassetti Foundation website. The posts received a lot of comments, and one of the most commented was a post about geo engineering called ‘Engineering a Solution to Global Warming’.

To summarize the argument we are talking about ways of cooling the planet using technological intervention.

One of the modes put forward and that I addressed in the post is to remove carbon from the atmosphere in an attempt to minimize the problem of global warming due to heat retention.

This week in Nature magazine a short article appeared that described an experiment that according to the researchers that conducted it seems to be the first time large amounts of carbon have been removed from the atmosphere and stored.

In the case in question scientists have used iron sulphate and the ocean. The iron is dropped into the water which causes a chain if events that pulls the carbon from the atmosphere, hopefully for good.

Ocean Fertilization Technique

The iron in powder form stimulates the growth of algae that lives for about 3 to 4 weeks. Their growth relies on carbon from the air, drawn through photosynthesis. When the algae dies or is eaten and excreted it sinks to the bottom taking all of the carbon with it.

One of the scientists involved in the experiments states that a single atom of iron draws 13000 atoms of carbon from the air, a large proportion of which finds its way to the ocean floor.

Many scientists are skeptical however. The amount of carbon removed is quite literally a drop in the ocean compared to that produced, and critics argue that this insignificant result could open the gates for other geo-engineering experiments, some of which (as my previous post outlined) seem rather unwise.

E-Waste and Computer Recycling

6 Replies Jonny Hankins

I am by no means a ‘techie’ as Christopher calls himself, but a quick look round my house reveals a quite astounding history. In various cupboards I find an HP desktop computer from about 10 years ago, very rarely if ever used, another obsolete Hitachi desktop from 15 years ago, my last Chinese laptop (the lid broke off), an IBM Thinkpad, an HP laptop, an old Vaio and even an Ollivetti laptop from 20 years ago.

I have never thrown them out for various reasons, one being security, another being that one day I might need my undergraduate dissertation for something and the third being that I want to know what happens to them when they are taken away.

Recently I have learned that all is not quite what it seems with recycling of computers too, and this makes my quandary all the more difficult.

Chinese workers take apart electronic trash on the street in Guiyu, China.

Several companies offer to recycle your old computer for you, and an enormous industry has grown up around the trade in old technology. In China entire cities have been born that specialize in taking our old stuff, but I feel that recycling is a bit of a big word to use for the ensuing process, as it has positive connotations. The computers are dismantled and all of the re usable pieces taken away, then the rest is dumped in a large pile. People from the surrounding areas scratch a living by doing a bit of home made scavenging, be that boiling components on their cooker at home or dipping cables in acid baths to extract the tiny bits of semi precious metals that they contain. Obviously this is done without regulation, and the results are often poisoning for those involved and the surrounding areas. See this photo essay about the city of Guiyu pictured above, probably the largest e-dumping ground on Earth today, and where a large portion of the products in question end up.

Another possibility is that the computers are shipped as donations to the Third World. These donations come in containers, not packaged in cardboard however but just thrown in, so although some do work, the majority don’t. The recipients have to unload them and try each one to see if it is usable. Those that don’t have to be dumped, and can be found piled up in heaps or abandoned by the roadside outside the larger African Cities, again to poison the ground etc.

This video from Ghana goes into greater detail.

India has some recycling sites and used to import waste for processing but now the problem is that the country itself is now a major producer of waste as it becomes one of the most technology saturated countries on the planet. And India is not alone, consumer societies all over the ex developing world are hungry for new technology, and obsolescence is just round the corner. This short article in Time expands upon the argument.

Large sums of money are involved as we would imagine, but the industry is practically non-regulated in real terms. Government regulation does exist but with the majority of the work carried out in the informal economy it is not adhered to, and dirty job as it may be it provides income for hundreds of thousands of poor migrant labourers.

And we are speaking about a problem that can only get worse. I personally don’t think it has to or should be like this however, it is not fair and it is exploitation, and so my question is ‘what can be done about it?’ Or more correctly ‘what can we do about it?’ We are the guilty party after all.
