Is online thrifting as fun as real-life thrifting?

Ever since I was a teenager, I always thought there was something magical about thrifting. Magical might be a weird term to describe what I felt but I mean, come on! Imagine going to a shop with no idea what you will buy and going out of it with 10 new outfits, some jewelry that was simply too interesting to leave behind, and even something to decorate the house; all purchased for the grand sum of €30. Sounds like magic to me!

Last year, I heard of Vinted, an online platform that allows you to buy and sell used clothes with other users on the platform, and I have to say, I was rather suspicious about its value proposition. The whole point of thrifting is going to some random shop or a clothing pile somewhere in a market and surprising yourself by finding some cool pieces….. Right?

Well, to my surprise, I fell in love with the application. The digitalization of one of my favorite activities turned out to be as fun as the real deal itself! Vinted not only made thrifting clothes as an activity available to me at any place and time but also allowed me to profit from it as now I sell pieces that I don’t wear anymore to people that might like them.

However, there are some aspects of having this activity digitized that go against “thrifting” as a concept. The main one being the overpricing of items on the application; the price of the sold pieces does not reflect the quality of the pieces and designer items are often sold for immense amounts of money. Now new startups are also trying to tackle this problem. One such startup is FENYX, the platform of which will allow individuals to unlock the total value of their belongings by highlighting alternatives to premature disposal and what the value of their belongings is at a certain moment.

With such exciting players coming to the field, it is certain that the market for online thrifting platforms or marketplaces is far from stagnant.

From the Tap Tap Method to Turbine-Crawling Robots

Picture: two wind turbine technicians performing the tap test on blades

Wind turbines are some of the tallest and most complex structures architected by humankind. Whilst everyone is aware that their purpose is to harness wind energy, thereby providing clean electricity to numerous residential customers, the public knows very little when it comes to how these turbines are inspected and maintained.

The costs to bring a turbine down to the ground once it has become operational are rather high; therefore, since this technology came to life until today, companies have used the “tap test” to inspect the turbines and detect potential problems (Andreisek et al., 2016).  The “tap test” is performed by wind turbine technicians, who get on top of the turbine, hang on ropes and tap along the helixes in order to detect any abnormalities. In case the “tap” inflicts a noise considered “abnormal” by the technician, the turbine is flagged for potential defects and brought down to the ground for further inspection (Andreisek et al., 2016).

Needless to say, this inspection method is not only outdated but it poses a life threat to the technician performing it. In addition, the method is an inadequate means of measuring the functionality of a turbine as issues are only detected in case the “tap” is different, thereby not allowing space for preventive measures.

To come to the aid of wind turbine operators, startups are racing to develop new technologies that can provide real-time data on the well-being of the turbines. One of the most original ideas, gathering considerable amounts of VC funding is that of turbine-crawling robots developed by BladeBUG (Hanley, 2021). BladeBUGs are set to replace wind turbine technicians as they will be placed in the blades to scan them through ultrasonic non-destructive testing, service mapping, localized mapping, and send the data to wind farm operators. This new method of testing will finally enable companies to harness the power of data and information systems to detect potential problems before they occur (Hanley, 2021).
