Latest Inventions

I mean, is biodegradable plastic such a good invention after all?

It always seems like an invention suddenly comes along and you think ‘wow, that is absolutely fantastic!’ - until you think it through for a bit longer.

Well this is exactly like that.

The invention is still a great idea - but the implications of it could actually have worse effects than before it was invented!

Why?  Well let’s follow through the life cycle of a plastic bottle and see what happens - but first - what is biodegradable plastic all about?

The Invention:
Regular plastics are made of polymers that can take literally for ever to break down.  They will do though - at varying rates - depending on the type of plastic they are it can be months or years before they start to break apart.

Now, we all know that plastics will never actually really ‘biodegrade’ in the sense of breaking down into total natural products that can be used again by organisms - but the word is used for the relatively fast breakdown of an entire container or sheet of plastic.

Now, this plastic is made to contain certain other particles that will help to induce and encourage the ‘natural’ breakdown of the item.  Just like burying a plastic carrier bag in damp mud will help it to weaken and fall apart.

So, anyway - they have come up with 2 types - Hydro-Biodegradable Plastics (HBP) and Oxo-Biodegradable Plastics (OBP) - and they work either by the chemical actions of hydrolysis or oxidation respectively to reduce the overall bulk of the product.

This then renders it into small enough pieces that natural bio-degradation can start to act on the remaining parts, reducing the product to it’s chemical components much faster than normal.
 
The Problem:
Normal plastics have been designed to be virtually indestructible, therefore you can use a plastic bottle over and over and over again. Even if you can recycle it - it is still as strong as it was before.

This was the original problem, meaning that plastic products never broke down:

Old Plastic Bottle: Brought new with product inside - product used up - container cleaned - container reused to carry another product - and another - and another -and another - then the container is recycled to start all over.

However, now this means that all new plastic will only have a short shelf life - too short for some - in fact, it is already making regular plastic fall apart as well!

New Plastic Bottle:  Brought new with product inside - product used up - container cleaned - container thrown in compost heap to degrade - the end!

So, how is it affecting new bottles?  Well - biodegradable plastics shouldn’t ever be recycled as it will compromise the quality and durability of new mixed plastics - basically it is starting to make recycled products less reliable!

If you buy a product in a biodegradable container, you must dispose of it after use - this means more plastic is being produced and thrown away than ever before!

At least with the regular plastic, you could reuse your toiletries bottles when travelling, use old pots and tubs for planting and store water and food over and over again.

Not with this new invention!  You will just have to keep replacing your containers and as a result, dispose of more plastic than ever!  And in fact, there are governments who are really getting angry about these new plastics and is trying to get them eliminated!

The Answer?
Well, we still need the regular plastic and we still want the biodegradable plastics!

Can they both co-exist or has 1 got to go?

I suppose it all depends on the person using it as to how beneficial each type is - to them and the planet.  Can you trust people not to recycle the new type - and can you trust people to recycle the old type?

Is it better to have lots of old plastic going around and around  - or only new plastic, but a higher production rate?

Well, maybe financially - it was a better invention after all!

Imagine lighting your rural home all night without the cost - and danger - of kerosene fuel and fumes!

Millions of homes in rural Africa are now all proud owners of the new eco lamp called The Kiran.  It is a simple solar powered lamp that is free to power and could save the lives of over 1.5 million people a year based on current statistics!

Now, that is a good enough advocate for this new lamp as it is - but it is also very eco friendly as well - and infact that is what it has recently won the Ashden Award 2010 for Sustainable Energy.  

The Lamp:
Basically, it is just a simple hand held lamp that harnesses the sunlight during the day, and releases it when needed during the evening.

However, it has been specially designed to be not only durable and cheap to produce and sell - but made to offer the same if not better lighting than the existing alternative: kerosene.

Over 75% of households in Africa have no access to electricity - and for those that do, the supply is not always 24 hour!  Therefore they have no alternative than to light with other means, and this is usually kerosene gas.  A gas that is known to gives of unpleasant and dangerous fumes when used internally or in badly ventilated areas.

Infact it is estimated that over 1.5 million people a year in Africa alone die from bad ventilation in combination with kerosene fumes.  Not to mention the cost of buying and storing the fuel in the first place - and the risks of house fires and personal injury.

Needless to say, D Lights small solar lamp eliminates all of that worry for the consumers!

It has 2 light settings depending on your use requirements and also has various positions for the handle so you can carry it, suspend it or fix it to a wall.  It’s fat base allows it to stand freely on a table of the floor as well. 

The Result:
This just goes to show you that the simplest things are still some of the best inventions!

Just the right design at the right time in the right place - and the invention is a winner.  I mean you have been able to get a chain of little solar lights for your garden for years now; but they didn’t win any awards!

They didn’t need to be so practical and so durable - and were infact made to be priced as profitably as possible rather than as affordable as possible!  Ironically it is the cost effective version here that is winning awards and selling millions of products.

So maybe you budding inventors need to think of something else simple and everyday that could be tweaked to make another great invention!

Get designing!

Imagine holding up a box of LEGO to a screen - and seeing a 3D image of the fully assembled model!

That is exactly what you can do right now, not just with that one ‘toy’ brand but with dozens of others - and the technology doesn’t just stop at games and gadgets - this new world of imaging could be appearing right in front of you in the street!

Soon, we won’t have to just guess what things will look like when made, we won’t have to guess where that repair store is on a busy high street - and you won’t even have to take your chances in a new restaurant without seeing the reviews of it’s past customers!

Augmented Reality (AG) - although first invented in 1968 by Ivan Sutherland - was truely brought to life in 1999 with the use of software that detected and reacted to ‘markers’ for image tracking.  Then it was developed the following year as a great way to bring text books to life with 3-dimensional images being more helpful than flat pictures - and basically - why stop there?

AG has been used for years on the TV - and watching the football teams pop up on screen as the players ‘warm up’ is a classic example; and showing the ’finish line’ over the river in a boat race is another ‘everyday’ use.  But we didn’t want an inanimate object - we wanted to be in charge of the images.

Initially driven by sales of merchandise, these AG software packages allowed consumers to ‘play’ with their gadget before buying it so to speak.  They could see images of their preferred product and even turn it around to see it from all angles before spending any money - even comparing the finished product to a similar one.

This is a huge step forward from the AG systems that need head mounted displays (HMD’s) to work.  Think back to when we thought that seeing computer information on the inside of your glasses was amazing - now it looks like you don’t even need the glasses!

The Future:
Well, think about films where computer screens seem to be on a whole table, the wall or even ‘floating’ in mid air and you can use your hands to move sections of it.  This could be coming very soon.

There are currently people working on whole room set-ups (spatial displays) that will allow you to overlay certain images into the space given - say for example looking at a new bathroom suite in your actual bathroom - try before you buy type of thing!  A new kitchen, lounge, office suite - the list is endless once you think about it.  But obviously it will have scientific uses first, like designing new hospitals, spaceships and whole environments maybe?

It is already being used in manufacturing - where the HMD’s contain step by step instructions that are triggered by the component parts and medical breakthroughs are also allowing layers of the human body to be seen simultaneously by surgeons to complete operations faster and safer.

So rather than a virtual reality - where you step into a computer generated world - this new reality is where the computers move into your world, and hopefully improve it!

However, I can imagine a hacker getting in to one of the programs and then a HMD AG fan could find New York City with wild animals or even aliens around every corner!

Your Basketball or Football can now be made with eco friendly materials at no extra cost to you!

It does seem that some advances in manufacturing could have taken place years ago, but it was all down to laziness that things stayed the same.

What I’m talking about is a sport equipment supplier that are now making all their sports balls (and more) out of ethically sourced materials.  This hasn’t really been done before as people we always happy (or at least not bothered) to change from the cheap and sometimes environmentally damaging alternatives.

All through history, people have found the easiest way to make something, and no-one ever complained.  If someone did offer up an alternative it may well have been a bit more expensive or a bit difficult to get hold of and as no-one really saw the point of changing - everything remained the same.

However now, things ARE changing.  People have found that previous products were damaging the very planet we live on, and even though the manufacturers were making a huge profit - we; the consumers, were only getting their products a little bit cheaper than the more ethical alternatives.  And so we brought the alternative.

The Brand of Ethletic are one such manufacturer, and have found that they can make sports products from sustainable and eco friendly materials, and sell them for virtually the same cost as ‘normal’ sports products.

So that is what they have done.

Their Products:
Ranging from basketballs, footballs, childrens sneakers, sporting accessories, brightly-colored baseball boots and even personalised balloons - all their products have an ethical claim and certification.

Whether it is FSC certified forestry for their 100% compostable latex, Fair Trade certification for their rubber and cotton networks, recyclable or biodegradable packaging or their use of only organic cotton - their products are certainly in a niche of their own.

And you can bulk buy products for your school, college or sports group so you get a fair deal too!  And you can choose the color, logo and other wording on them too!

Now there is no need to NOT buy the Fair Trade version of anything really, as these products are becoming more and more available thanks to new manufacturing and retail developments.
