Elon Musk have change the car industry with Tesla, and projects like Hyper loop and SpaceX often reach the news. But in this interview he talks about how he want to change the way we build tunnels for cars by changing the tools and the requirements for the tunnel. It is interesting to see how he adress a problem and how he step-by-step working towards a solution. Look at the interview about 3D tunnels and the future for Elon Musk.

You drop the diameter by a factor of two and the cross-sectional area by a factor of four, and the tunneling cost scales with the cross-sectional area. So that’s roughly a half-order of magnitude improvement right there. Then tunneling machines currently tunnel for half the time, then they stop, and then the rest of the time is putting in reinforcements for the tunnel wall. So if you design the machine instead to do continuous tunneling and reinforcing, that will give you a factor of two improvement. Combine that and that’s a factor of eight.

Everybody interested in, and concerned about, the now ongoing digital revolution and its impact on business, on the economy and on society should read the article; Where is technology taking the economy? The article is written by Professor W. Brian Arthur and is published in the McKinsey Quarterly October 2017.

The credibility of the article is supported by how nicely it connects to “Part I – How
technology drives economic and social transformations”
in Robert D. Atkinson´s 2004 book “The Past and Future of America´s Economy / Long Waves of Innovation that Power Cycles ofGrowth”. A book that is instrumental in order to understand the mega impacts of disruptive technology systems in general and the digital revolution in particular. For this reason is that book since a decade required reading at the Executive Program in Industrial Management at KTH EXECUTIVE SCHOOL.

Despite the limited size of the article, Professor Arthur succeeds in vividly providing the reader with:

Christian Pleijel, Director Sustainable Urban Systems at KTH Executive School has been invited to speak about his project on Greening the Island conference on Siciliy the 3rd of November. His project is nominated to their award.

Ecological and social project outcomes

Freshwater is a strategic resource on islands, often scarce. Saving water means becoming more resilient and sustainable. The energy cost for procuring water to these 8 island societies varies from island to island, but given modern osmosis processes to produce desalinated water in general need 2 kWh/cubic meter, the energy saved can be estimated at 304,010 kWh/year and the reduction in CO2 emissions as 39.050 kg/year.
