It has become a commodity to track your health and performance through the use of wearables. This includes counting the steps you have walked in a day, evaluating how good you have slept last night, tracking progress in workout or training for a marathon. Gathering this data and evaluating it can be very useful when confronted with health problems or by just being a motivational factor for exercise.

However, when considering swimming this has yet been rather difficult. There is the possibility to track data with a smart watch, however wearing a watch while swimming can hinder your training. Whether being a professional or swimming as a leisure activity one is faced with the struggle of counting laps instead of trying to improve your technique and evaluating your performance.

A start-up called “Form” from Vancouver has been working on AI swim goggles with which real-time data from the swimmer in the pool or open water can be not only collected but directly brought into the line of sight when swimming. The holographic technology by Sony is promised to display graphics such as stroke rate, distance, and split time, while at the same time providing enough sight to see where you are swimming. These goggles could evolve as a game changer for training, in particular in terms of improving your performance with real-time data while swimming. This would lead to the possibility of improving one’s swim technique immediately instead of waiting for the recommendations of a trainer at the end of a lap. Also, when training towards a competition or triathlon, a device which evaluates real-time data would definitely help in terms of preparation for the competition. Further, swim data can be evaluated within an app by swimmer and trainer after the training.

Up until now these glasses are priced quite high ($200) and will therefore only attract customers who are willing to test the new technology and are professionally training for a competition. However, when this technology is proven and further extended, it might lead to additional features in terms of an entertainment perspective when training in the pool. These might include the possibility to watch movies or competing in games in terms of bringing the virtual world into the real world.

Data centres are a fundamental part of today’s modern computing infrastructure. Each click online and every mail sent is information stored in data centres. A critical requirement in order to run a data centre is the uninterrupted power supply. Consequently, the energy demands of these data centres are enormous. As the end-consumer demands instant access to the Internet and mails, most data centres have a backup diesel generator to insure power supply at all times.

In fact, today, data centres require 2% of the total global energy consumption. It is forecasted, that the demand for computing devices will only rise further in the next years and the number of IoT devise will amount around 20 billion by 2020. Undoubtedly, the need for more data results in the need for more data centres. Researchers predict that data centres will consume 1/5 of the earths power by 2025.

In order to relate power generation to carbon emissions one must consider the energy mix (from which sources power is generated) of a country. In China, for instance ¾ of the power generation is still based on coal plants. This results in their data centres emitting carbon emissions equivalent to 21 million cars.

As the awareness to reduce carbon emissions and power consumption is at an all-time high, this challenges companies in the ICT sector to address this problem. But how?

Creating power through renewable energy sources is one measure to reduce emissions. Companies like Google and Apple have already reacted to this issue and reached their goal of supplying their global operations (data centres, retail stores, company HQs…) only from renewable energy sources. Amazon, Microsoft and Alibaba set their aims for achieving this goal within the next decade. For example, in the Netherlands, Google has acquired a wind farm through a PPA (Power Purchase Agreement) which supplies not only their data centre in Eemshaven but is giving renewable energy back to the community at the same time.

Another aspect would be the reduction of energy consumption in data centres. Companies compare their PUE (power usage efficiency) of data centres in order to efficiently reduce energy. Cooling, in conventional data centres, takes up 40% of the energy in a data centre as well as a lot of water. In order to tackle this problem, companies have tried to find innovative cooling solutions in terms of matching their system towards weather and other factors.

Essentially, ICT companies will be challenged to raise data centre storage efficiency and at the same time lowering energy consumption or change to renewable sources of power generation in order to keep the environmental impact of the industry in check.
