Startups and SDGs

Mon, 05 Sep 2022 00:00:00 +0100

As an electronics engineer, you have a superpower: the ability to design and create technology that can change the world. Over the course of your career, you’ll spend around 80,000 hours working. That’s a significant portion of your life, and how you choose to spend that time matters. By aligning your work with the United Nations Sustainable Development Goals (SDGs), you can ensure your 80,000 hours are dedicated to making a positive impact.

The Carbon Impact of a Private Pilot Licence (PPL)

Sun, 15 May 2022 00:00:00 +0100

What influences the carbon emissions?

How much you fly?

The standard UK PPL mandates a minimum 45 hours of flight time. Many students will complete their PPL within this minimum number of hours, but others will take more time. Clearly, the more hours you spend in the air, the more carbon emissions will be generated.

What you fly

Most flight schools will use small, fairly fuel effecient aircraft. The Cessna 152 is a small 2 seater that is great to learn in. The Cessna 172 and the Piper PA28 are also common 4-seater options, for those who feel the 152 is too small. Check what options your school has and ask about fuel efficiency of their fleet.

Scalable off-grid energy services enabled by IoT: A case study of BBOXX SMART Solar

Sun, 01 Oct 2017 00:00:00 +0100

This case study intends to show how Internet of Things (IoT) technology can be used to tackle development challenges by studying the example of BBOXX and its SMART Solar platform as applied to Solar Home Systems. It aims to highlight the benefits of such technology to its users and how it can be utilised to create scalable business models through user-centric design. However, it also shows the difficulties in designing, developing and deploying appropriate technologies in an affordable and impactful way. Similar applications in the water and agricultural sectors are looked at to further explore the potential and the challenges of IoT technologies in driving social and economic development. The case study raises ethical questions about the storage, collection and sharing of data and explores whether the data protection models prevalent in the developed world are applicable in a development context. It offers ideas for future research and points to the need of including financial, socioeconomic, and ethical considerations in the processes of innovative solutions development.
