What if you could 3D-print food? A team at Columbia University has experimented with printing dough, meats, vegetables, sweets, made a seven-ingredient slice of cheesecake, and chicken samples that were then cooked by lasers. In this episode, researcher Jonathan Blutinger explains why 3D-printed food could transform cooking, and when listeners may be able to buy one of the printers for their home.

Motors are driving the zero-emissions race to electrification, but what if we could make them smaller and more efficient? David Calley, who spoke to Lexicon at CES 2023 in Las Vegas, is one entrepreneur working on the issue. His company, Arizona-based Elemental Motors, is digging into more efficient designs that could offer five or more times the torque density than comparably-sized motors. It could power robots, industrial applications and eVTOLs, paving the way for improvements in mobility.

Was there ever oxygen on Mars? An experimental study in December 2022 revealed it’s not likely, as part of research that could reveal more about whether life on Mars is possible. As entrepreneurs like Elon Musk and others chart a course for a city on the red planet, Lexicon takes a look at what awaits the future visitors.

Tune in to learn more about the benefits of repairing industrial technologies instead of replacing them.

Join us in this episode of Lexicon as we delve into the mysterious world of processor architecture and examine how RISC-V, an open standard, is shaking up the industry dominated by major tech companies. Learn about the implications of architecture choice for our devices and the potential benefits of a more open and accessible processor ecosystem.

Back in January, Kyle Monson began a 90-day trial of using ‘AI Interns’ as part of his creative team. Part publicity-stunt, part serious experiment, Kyle wanted to see how his teams could incorporate the use of tools like ChatGPT, Bard and Midjourney to assist with creative work, experiment, learn, and have some fun.

In this episode, IE caught up with Kyle to find out what he had learned, and whether he planned to take Aiko and Aiden on full-time.
