Can We Improve the Health of the Planet? A Series.

“Have a bias towards action – let’s see something happen now. You can break that big plan into small steps and take the first step right away.” – Mohandas Karamchand Gandhi

A couple of weeks ago I read Christopher’s article on this blog entitled ‘We Need to Act on Climate Change For The Sake Of Others’ and it started me thinking about green technology.

Scientists are in general agreement that the Earth is warming, there is plenty of debate as to why however. A large proportion claims that this warming factor is caused (or at least worsened) by human actions such as burning fossil fuels and deforestation.

Members of this group therefore believe that we need to produce energy without burning fossil fuels and that we should take other steps to avoid releasing carbon into the atmosphere such as stopping deforestation (incidentally this is cause number 1, burning fossil fuels is secondary in comparison). I should say I count myself amongst them.

An unhealthy planet

Every Thursday over the next month or so I am going to post one of a series of articles that will look at different aspects of these problems. I want to propose an argument that I borrow from the sociological study of science and is directly drawn from an economic analysis. It is simple, and should be borne in mind when reading the posts.

When we think about costs we only think about money. How much for example does a litre of petrol cost? Or a flight to Boston from London? “Oh $3.50 a litre” or “$1200 dollars” we might say. But this excludes social and environmental costs that should be added on, a bit like governments add on VAT.

The real cost of my litre of petrol should include various other factors. How did the raw materials come out of the ground? Did the company leave a mess and pollute the local drinking water in the process? How was it refined, and transported? How much did the local people who live nearby suffer or benefit from its production? And finally how much pollution will it cause when I burn it?

And here we have a sliding scale, LPG is environmentally less damaging and therefore environmentally cheaper than petrol. By this logic natural gas might be cheaper than wood to heat your house too (unless produced through fracking some would argue), and taking the train might be cheaper than taking the bus. I hope this is a little clearer than a bland phrase about ‘going green’  and offers a slightly more defined point of view.

The series will be structured something like the following:

  • Environmentally cost efficient transport
  • Electricity production
  • Engineering climate change
  • Problems faced and the miracle cure
  • Conclusions and a review of comments

I hope to present you with some interesting new technologies that really offer a much ‘greener’ future, as well as looking at some of the ways that different institutions view and approach the problems that I will address.

I am certainly not pessimistic about the future but I don’t believe that ‘technology will save the day’ on its own, but a little thought and a few small actions from a lot a people can make an enormous difference (as someone once said).

I hope you will follow and comment, and don’t hold back on your criticisms, that is what I am here for.

Are bionic suits a thing of fantasy or the future?

So, to the article! Everyone has heard of Iron Man – well I would think they have. The idea that such a suit could become a reality, is well… fiction. Until now!

A technology company called Raytheon has developed an exoskeleton, designed to effectively act as a bionic/robotic suit. The suit is designed to perfectly mimic and aid human actions, so the wearer can feel normal whilst performing tasks that they could never achieve without the aid of the suit.


One way of thinking about how it feels is to think of the power steering in a car. Without the power steering it can be really tough to turn the wheel, activate the power steering however and the car still feels normal and responds in the same way, the difference is, minimal effort is required to do a rather demanding task.

Doing press-ups in a bionic suit with ease

Performing everyday tasks is easy when wearing a bionic exoskeleton!

The suite has the potential to be fitted with some sort of amour plating, to protect the individual form attack – assuming it were to be used in a war-zone, and not in industry! D3O could actually make it a pretty invincible suit!

The suite can help the wearer lift up to 17 times what they could normally life, making tasks 17 times easier! A massive positive is that it doesn’t restrict the wearers range of motion, meaning that they can more freely and normally.

There is a problem though. The suit has to be attached to an external power source, as it guzzles power like crazy. Current batteries are either too weak, or too dangerous. For example, lithium-ion batteries can’t be strapped to a human, as they are prone to explosion if they get damaged!

A lack of power makes the suit extremely heavy, meaning that every movement becomes more difficult. This means that if there is a loss of power, the suit is hindering, rather than helping the occupant.

Aside from the lack of power, the main difference between the suit Raytheon have developed and Tony Stark’s suit is that Tony Stark’s can fly. Stark’s suit is also loaded with flairs, missiles and weapons galore, and has Stark’s supercomputer Jarvis running the interface. Raytheon’s suit is still in the early stages though, and no doubt will soon catch up 😉

Can green technology help us get out of the red?

Most people know that the world has recently emerged from an economic recession. Many people also know that we are all dangerously close to slipping back in, and are replying on governments around the world to keep us in the black.

However, has anyone thought about green technology as a way of helping steer an economy back to growth and prosper?

Well it would appear that Scotland might be doing just that, as they are trying to encourage as many as 600 companies to move into the ‘green economy’ in order to boost profitability. The green economy consists mainly of renewable energy sources, and low-carbon technologies.

Scotland seem to have recognised that there could soon be big money in this industry, hence the drive towards getting more firms into the industry.


In its attempts to become the industry leader in green technology, Scotland’s Finance Secretary, John Swinney has said that he wants to increase exports 50% by 2017 and encourage inward investment in green and low-carbon technologies.

Unemployment seems to be a problem everywhere at the moment, but Mr Swinney’s new ‘green growth’ plans are likely to create around 130,000 jobs by the year 2020.

What do you think, is Scotland taking a step in the right direction by investing in green technologies, or is is a risky option to take given the current global economic climate?
