🚀Startups Nuts
A team of engineers from MIT and China have designed a solar desalination system that passively turns seawater into drinking water. It circulates water in swirling eddies, which when combined with the sun's heat drives water to evaporate and leave salt behind. The resulting water vapor can be condensed and collected while the leftover salt circulates out of the device rather than accumulating and clogging the system. A small suitcase-sized system could produce up to 6 liters of drinking water per hour and last several years.
A startup called Aquagga has successfully deployed a PFAS destruction unit housed inside a modest 10-feet-long by 8-feet-wide shipping container - PFAS chemicals are great at deflecting water, stains, and grease, but the long-lived chemicals have contaminated drinking water everywhere.
🏭Business Nuts
Amazon launched its first Project Kuiper satellites on Friday. The project, which was announced more than four years ago, aims to build a network of 3,236 satellites in low Earth orbit to provide high-speed internet access anywhere in the world. Amazon plans to invest more than $10 billion to build the network. The company has kept the size and design of the satellites secret, only sharing photos of the shipping containers that carried them to the launch site.
Billionaire investor Ken Griffin’s flagship hedge fund rallied last month. The person said that Citadel’s multistrategy flagship Wellington fund gained 1.7% in September, bringing its 2023 performance to 12.6%. The S&P 500 pulled back 4.9% last month, suffering its worst month. The equity benchmark is still up 11% for the year. The market has grown more volatile and fragile as investors grapple with a higher-for-longer interest rate regime.
📱Tech Nuts
Meta's Quest headset marketing plans changed in response to Apple's Vision Pro announcement. The company plans to release a VR headset without controllers next year. It will shift away from a heavy focus on the metaverse and lean more into pushing the practical uses of the headset. The next headset should be cheaper than the Quest 3.
LLMs allow users to ask anything and almost get an answer to everything. However, the answers it returns could be wrong, and even if the answers are correct, they might not be the right way to solve the problem. They are probabilistic models that provide the most probable answers. Large language models are currently a general-purpose technology that can do some theoretically magic stuff, but for many people, they still look a bit like the PC ads of the late 1970s that promised computers could be used for anything.

The SP80 and Syroco teams have built two boats designed to beat the current world sailing speed record of 65.37 knots. Both teams are using huge kites attached to the boats and aim to achieve a target speed of 81 knots. This article takes a look at how both teams are progressing with their projects. Pictures and videos of the sailboats are available.
