16 tech projects from 2023 that could change the world


Challenges like climate change and dwindling natural resources and can make the future seem uncertain and even scary. But our fate isn’t sealed so long as scientists around the world have a say. They’re busy dreaming up technologies, from the practical to the zany, that could make the future a little brighter. 

Prototypes for Humanity, a Dubai-based organization that runs a contest to spur innovation, has highlighted 100 projects in 2023 that they believe could change the world — from electrical skin to devices that predict air pollution without any air sensors. Here are some of our favorites.

Real-time monitoring to predict natural disasters

NatCat aims to use satellite imagery, remote sensing and machine learning to assess the risk of natural hazards in different locations, which could help to reduce the risk of harm for those living there. The tool generates risk assessments for any location in the world, regardless of the availability of local data. It can also use climate change data to project the frequency and intensity of some natural hazards in the future.  

Converting air humidity to electricity

This project, called Electric Skin, creates a self-powering biomaterial for electronic devices that harnesses the electrically conductive properties of the mud-dwelling bacteria known as Geobacter sulfurrenducens. Specifically, the bacteria’s protein nanowires can generate electricity from the air’s ambient humidity. The scientists have extracted the bacteria’s DNA and embedded this into E. coli for production. To create the power source, the team placed the nanowires harvested from E. coli into compostable biomaterials to create a flexible and textured membrane that can power electronic devices from the air and water.  

Recycled tiles that regulate heat and humidity

Spurred by the excessive production of non-recyclable plastics alongside the effects of climate change in south India, Wastly Roof Tiles aims to replace conventional roof tiles with tiles made of a recycled material that can reduce indoor temperatures.
