Water Filters in a Book

Dr Teri Dankovich, a researcher at Carnegie Mellon University in Pittsburgh USA has developed and tested a book whose pages can be torn out and used to filter drinking water. Trails are impressive, with the process bringing the water up to US drinking water standards.

The book’s pages contain nanoparticles of silver or copper, which kill bacteria in the water as it passes through. Some of the particles do remain in the water however, but they remain within the legal limits.

Nanomaterials

Now here I have to add my own input to the debate. As readers might know I have written several posts about nanomaterials and it is one of the fields that I work in, and I would question how legal limits are defined.

Nanoparticles are treated like any other particles, and their scale is not taken in account, but this seems to raise some questions. The fact that they are so small means that they can pass easily into the blood stream, so their effects may not be the same as larger particles of the same materials.

So I have to leave an open question mark over the legal issue, but the fact that the water is drinkable is a great advantage. And this leads me to ponder the fact that innovation, and its level of responsibility and ethical justification, must be local. An invention or innovation that brings drinkable water to millions, is portable and cheap and could save many lives, must be seen within its context. Nanoparticles in the water in this situation, may not be same an nano particles found in water because of factory pollution or deliberate addition when other processes might be readily available.

An article on the BBC explains that “All you need to do is tear out a paper, put it in a simple filter holder and pour water into it from rivers, streams, wells etc and out comes clean water – and dead bacteria as well”. And one page can clean up to 100 litres of water. A book could filter one person’s water supply for four years.

The project is looking for funding, so if you are interested and have some money to spare click on the link at the start of the post and pass them over your pocket money.

As a final thought, nanotechnology has come in for criticism from the academic community for its lack of regulation, and rightly so. But it also brings a world of possibilities, many of which like the story above that could transform people’s lives. This is the fine line that interests me in my work, how to make the most of scientific developments at the least environmental and social costs, and for the highest number of people.

How to be a little greener

We all leave a footprint on the world, just by being alive we contribute to environmental degradation. No matter what you do, you can’t eliminate your effect (offset it maybe) on the world, but you can minimise it.

In this article I am going to look at some very simple things you can do to reduce the impact you have on the planet, making you a greener individual.

Water Usage

The amount of water we use has a big impact on the environment, as well as other people. Last April I posted an article which asked you to question your usage of water. I have included a brief summary of the article

Of all the water on earth, just 0.007% is drinkable, and whilst our usage of water and the number of people on earth are both rapidly growing, water supplies aren’t. Drought is a real issue in many areas of the world and one in nine people don’t have access to safe drinking water.

Rainwater storage tank

Wall mounted water butts are becoming more popular – a great way to collect and store rainwater.

Excessive use (and arguably wastage) of water via things like regular use of hose pipes and using water hungry appliances (like washing machines) when they have spare capacity, can easily be reduced, and can significantly decrease our water usage.

In the comments, there was some great feedback. Jonny suggested using a water butt to collect rainwater to water your garden, saying “it is really shocking to think that many people use drinking water to keep the lawn green“. Shane told us how he plays 5 minute songs when having a shower, so he know when it’s time to get out, and Jean noted how he tries to fix leaks as soon as he finds them, as they are a massive waste of water – and money!

Buy Local

Another step you can take which will reduce your carbon footprint is choosing local. In 2009, I wrote an article on the technology behind food, discussing the journey food takes, and the impact it has on the planet, getting it to our table. Although the figures might have slightly changed, the concept behind the article is still the same: buying local produce significantly reduces your carbon footprint.

Local doesn’t even have to mean that close. Ideally, within 20 miles of the shop you buy is the best sort of ‘local’, however even food that has been grown within 200 miles is much better than food that has been flown across the globe.

Local food not only promotes energy conservation, but it also supports local farmers. Farm shops are a really good place you can get local food, why not check out BigBarn, a site designed to help you find where you can get locally produced food.

Farm shops are a great place to source local food.

Reuse, Repair and Recycle Technology

It is important to use technology to its full potential, and to keep using it until it is no longer viable. Once something stops working, or is no longer able to fulfil your needs, whenever possible, repair or upgrade it. If your PC is starting to run a little sluggish, try to speed it up again (maybe visit my speed up your computer article) add some more RAM, upgrade the graphics card, and consider increasing the storage capacity.

As Jonny wrote last year, electronic waste is a real problem, computer components can be hard to recycle, and are often toxic. Therefore it is important to try to reduce electronic waste, and when it does occur, ensure it is disposed or/recycled properly.

If you have reused and repaired a device as much as possible, the next step is recycling. Recycling electronic waste is a growing industry, computer recycling and schemes which enable you to recycle mobile phones, so your technology is either properly recycled, or repaired and reused, either resold locally, or distributed to developing countries are becoming ever more common. Many firms (like the one I link to above) are even paying you for your old technology – reduce your ecological footprint, and get paid, what more could you ask for!

Save Energy

There seems to be a growing resistance to nuclear power, fossil fuels are running out and this matched with the lack of investment in renewables, is leading us to a global energy crisis. Every individual can make a difference, by reducing their consumption.

Electrical energyTurning off devices instead of leaving them on standby, switching to energy bulbs, and insulate your home and relatively simple and cheap ways to save energy, which we have probably all heard many times. Steps which involve using smarter technologies, such as getting Remote Heating Control installed and choosing smarter energy using devices are also good ways to save power, and are now also becoming more common.

In Summary

Four of the best ways you can reduce your environment impact are to: be more frugal with water; try and buy local produce; maintain technology for as long as possible, and then recycle it; and reducing your energy usage.

The Gadget Show Live 2013

The Gadget Show's 'G' logo at The Gadget Show LiveOn Sunday the 7th of April, I went to the Gadget Show Live at the NEC in Birmingham. It was a really great day, and I want to share the experience with you, I just haven’t had time to finish this post!

First of all I must give thanks to British Gas, who were very kind to give me tickets to the sold out event. As you may know, thanks to a collaboration between Technology Bloggers and British Gas, I have been able to step into the future of smarter living, and experience how technology has the potential to improve our lives. The technology I tested was of course their Remote Heating Control system, and I got to try it a few months before the national roll-out; I reported my findings via a series, which British Gas later posted on their website.

The day was very good fun, and I live tweeted from the event – take a look at our Twitter account and you can find some of the Tweets.

There was a lot of technology on show, some of which was cutting edge stuff, just being brought to the market.

Super Show

I had tickets to the ‘super show’ which was an event in which the three presenters of the Gadget Show: Jason Bradbury, Pollyanna Woodward and Jon Bentley, showcased exciting gadgets, offering various prizes to members of the audience. The show was good, however it did feel slightly commercialised, as pretty much every third word was plugging a product!

Smarter Living

After the show, the first stand (there were hundreds!) I visited was the British Gas stand. They had been kind enough to send me to the event, so I thought it only fair to pay them a visit!

They had designed their stand to look like a home, and had equipped it with all the very latest smarter living technology. Their Safe and Secure security system, Remote Heating Control and smart meters were all on show. It was very well designed and the complimentary Stuff magazine was appreciated!

Microsoft

A tweet I posted about the Gadget Show, had attracted the attention of the team at Microsoft Windows UK, and they invited me to check out their stand, and to use their bloggers lounge.

As the main sponsor of the event, Microsoft got a pretty big stand – making it hard to miss!

Microsoft's stand at The Gadget Show Live 2013On their stand, Microsoft were showcasing many of their different software and technologies, including IE 10, Windows 8, Windows Phone, Surface, Bing, 3D scanning software and a real time, 3D webcam!

There was quite a lot on display, and the amount of technology was quite impressive, that said, as the event was so busy, they needed it all, as their stand was quite crowded at times.

I got talking to the person manning the 3D printing section, and was then offered (as a blogger) to go to the bloggers lounge. There I met some great guys from the technology giant, including the faces of @IE_UK and @WindowsUK, and the Senior Product Manager for Windows at Microsoft UK. I was given a tour of Surface and IE 10, and got to test them out for myself. I was quite impressed.

I love Windows 7 and don’t have any problems with it, so I have never really thought about upgrading to Windows 8, however having been given a Windows 8 license, I am going to test it – expect more soon!

AQUAdue Loo

There was some really innovative technology on show this year. One example was AQUAdue‘s toilet system, when you need to flush, a tap which runs into a basin on top of the loo, starts to run. Use this to wash your hands, and it fills up the toilet for the next flush. What a great idea to save water and space!

3D Printing

3D printed TARDIS cufflinks.

The 3D printer Microsoft were using on their stand was an Up! 3D Printer. On another stand there was a firm called Denford Ltd there, who were showcasing the capabilities of a 3D printer. Probably the best giveaway I got from the event were some 3D printed TARDIS cuff links – as a techie, and a Doctor Who fan what better freebie could you get?

The technology has been around for a few years now, however it’s now starting to become mass market. Fancy a 3D printer? Well they aren’t as expensive as you might think, here’s a link to somewhere you can buy an Up! Mini 3D printer for less than £1200!

3D printed objects

An Up! 3D printer and some printed objects, included a printed TARDIS, castle and Yoda.

Microsoft were also using the Up! 3D printer to showcase their 3D scanning technology. You could get your head scanned, and then a miniature version printed out, right there and then – how cool is that! Gadget Show presenter Jason Bradbury seems to think so too, as he went to get his head scanned and printed! Take a look below.

Too Much!

It was a really great day, and there was far too much there for me to talk about it all. Some of the best bits I have mentioned above, there’s loads more that I haven’t mentioned, mainly because I don’t want to run too far over 900 words – people tend to switch off after that!

I think from the number of tweets and images in this post, you can see that there was a lot going on 🙂
