This is a sustainable design. The generator provides a constant stream (in the long run) of biogas, the oxygen used up in burning it is replaced by the growing algae and the released carbon dioxide is actually required for growing algae[5]. Because none of these processes make or destroy matter, all the quantities add up to equal amounts, meaning that burning biogas produced in this manner does not produce any waste or require any fuels that are not already part of this system and constantly cycle, maintaining each other. Biogas also has the relatively high energy density (890 kJ/mol)[17] and is very simple to use like fossil fuels, by burning. If this were to be in widespread use, minimal alterations would have to be made to the vehicles currently in use[18].
Our designs were made with sustainability in mind. This system isn’t simply another technology, it’s the same technology used differently. Biogas generators have been in use for years in different areas of fossil fuel use and waste recycling[19]. What is different about our design is that the original intention was not how to produce more fuels or recycle more wastes, it was how do we deliver the same advantages of fossil fuels to the consumer without a catch. And this is also the point of the Sustainable philosophy, you do not provide products, you provide advantages.
Record industry
Similar improvements could be apparent in other industries, resulting from the different way of thinking during the design of their systems of production. Take the record industry for example, currently this is an industry challenged with technology of the day, where their main area is stacking up their costumers with optical media (CDs and DVDs) which are now obsolete and provide their costumers with no obvious advantage, given other technology of the day. If the record industry had planned with Sustainability in mind their purpose would instead be delivering multimedia content to the consumers, rather than discs. If this were the case one would assume they would have come up with the idea of using a communications network for the purpose a long time ago.
Serving drinks
For a most down to earth example of the differences in thinking, let’s look at the area of serving drinks automatically. The vending machines in use for this purpose today offer your drink in a colourfully printed single-use can or single-use thin plastic cup, convincing you to drink it with large advertisements. This is because from the provider’s point of view, the point is in selling as many as possible and all comfort and ecological concerns are secondary to that. In a Sustainable design, the industry’s focus would be on supplying the consumers with drinks, rather than selling them as many cans as possible. In this approach attention could shift to providing better drinks and comfort of use (drinks could be served in comfortable reusable mugs rather than single use cups), advantages good for the consumer, rather than colourful cans and advertising, which offer no advantage for the consumer. The reasons for this are: Firstly, the provider will be encouraged to look for cheaper ways to deliver drinks with minimal overhead, secondly the provider littering the consumer’s living space will not seem acceptable to the consumer, thirdly the consumer’s right to interact with the provider will not abruptly end on purchasing a product as the sold will be a service rather than an individual product.
It is noteworthy that Sustainability in this case also has clear advantages for the provider. The drop of of sales here is an illusion, as it is realistically very unlikely the consumers will ever buy more drinks than they desire simply due to being tricked into it. Sustainability ensures more permanent and reliable consumer relationships, which provide a dependable stream of income.
Part 4 – Sustainable design
Ultimately the place where the change in way of thinking makes the biggest difference is in the mind of the engineer responsible for designing these systems of production. Here are some recommendations:
- Always keep up to date with newer technologies and obtain general understanding of the natural processes that can complement your production process to make it sustainable. Detailed understanding is not required for the educated guess expected of you, yet basic understanding will allow you to see solutions to systemic problems you may have thought unsolvable (e.g. How to provide a sustainable option for a reliable source of electricity).
- When doing feasibility studies, always consider and emphasize the sustainable option. Your costumer is relying on your expertise to provide solutions that are best for them and sustainability is excellent for all of us.
- Sustainable solutions guarantee investment return. Be sure to mention that. Unsustainable solutions may seem cheaper on the short term, but will always have poorer investment return than sustainable solutions. An unsustainable solution has limited lifetime and often maintenance costs that depend on the market situation (cost of oil, electricity), while a sustainable solution is capable of generating a constant stream of return forever and maintain itself by design.
- It is always possible to obtain a sufficient loan, to cover your initial investment. Sustainability is the smart option. It will pay out on the long run.
Conclusion
By properly understanding what Sustainability really means, we have moved the term away from being an expensive buzzword of the modern world. We have shown that Sustainability is in fact something that makes sense both in the engineering and economical sense. It is something that is good both for the industry as for the consumers. We have shown that Sustainability is not another nonsensical drain on your money that you are forced into by the ecologists, instead by taking it into account early enough into the design of the facilities of production, you can use it to increase your long term returns and lower the risks involved.
Eventually, all of our systems will have to be Sustainable if we want to survive. However, it is important that we start now. Sustainable solutions may not remove the environmental damage we have already caused, but they will begin to remove the cause, before the effects become too taxing. By starting to design systems with Sustainability in mind now, we allow us the chance of a smooth transition from exploiting our environment, to using it intelligently. There is nothing to loose.
