Tenedos #003: Tesla unveils its humanoid robot, methanol cars, Ethereum energy-saving upgrade, building Sim-like digital cities
This week we talk about (1) the unveiling of a humanoid robot prototype from Tesla, (2) China betting big on methanol cars, (3) Ethereum’s long-awaited energy-saving ‘Merge’ upgrade, (4) how today’s technologists are pitching a vision in which players don’t just control Sims-like characters, they become them.
▶ 📧 Welcome to Tenedos
I round up the best articles of the week and send them to a group of people who are as passionate about the world of technology as I am. I do this to keep up with this rapidly changing world. My main areas of interest are emerging technologies, blockchain and the world of innovation in general.

▶ 📚 In short
- Are we witnessing the beginning of the humanoid robots mass production era? Last Friday Elon Musk has unveiled the humanoid ‘Optimus’ robot at the Tesla’s AI day [link, #robot #humanoid #tesla]
- We hear a lot about electric cars, but what about alternatives? China is investing on methanol cars as an alternative to electric vehicles [link, #methanol, #methanolcars]
- Ethereum, the second largest blockchain network after Bitcoin, finishes its long-awaited energy-saving ‘Merge’ upgrade [link, #ethereum #ethereummerge]
- More than three decades after SimCity, tech companies, retailers and governments are using the game’s basic building blocks to create three-dimensional worlds [link, #digitalcities, #smartcity, #simcity]

▶▶ Humanoid robot unveiled at Tesla’s AI Day
A prototype of the humanoid robot ‘Optimus’ took the stage and greeted the seated audience. A video was shown in which the robot carried a box, watered plants and moved metal bars in the automaker’s plant.
Are we observing the beginning of the era of mass production humanoid robots?
▶▶ China is investing on methanol cars
Methanol (commonly called “wood alcohol”) is a simple organic chemical that can be produced from a variety of sources, including coal, natural gas, biomass, and captured carbon dioxide.
As a fuel methanol is as powerful as traditional fuel, but greener. It has already been widely used in race-cars because it gives the engine more horsepower while keeping it cooler.
In some scenarios like long-haul transportation, methanol-powered vehicles can be more affordable and dependable than EVs.
▶▶ Ethereum finishes its long-awaited energy-saving ‘Merge’ upgrade
The Ethereum, the second largest blockchain network after Bitcoin, completed the crypto world’s biggest and most complicated software upgrade to date (according to its co-founder Vitalik Buterin).
Called the ‘Merge’, it replaced power-hungry computers that were used to order transactions on the network with a more energy-efficient set-up using piles of the network’s native token, Ether, placed in special, so-called staking wallets.
As a result, Ethereum’s energy consumption will decline by an estimated 99%.
▶▶ How do you build a digital city?
Today’s technologists are pitching a vision in which players don’t just control Sims-like characters: they become them.
While nothing, or very little, exists today that holds all the component parts of a city in one cohesive package, individual developers and large corporations are creating metaverse spaces that could function as essential parts.
