Our laundry tip for the future: separate whites, colours and touchscreens. NUS built a touchscreen sleeve that survived 50 washes. Battery and controller: still outside. A screen made of thread. Not yet a computer in a sweater. Would you wear it? 👇 #LogicBeforeAI #Wearables

A geothermal energy plant in western Türkiye. ♨️ The geology: mostly rain in hot rock. Rain is terrible at glowing. 🌧️ Here, the water goes back down. Most of the CO2 goes up. Save this. We did. 🔖 #LogicBeforeAI #Geothermal

Storing 100 MWh in a gravity battery is simple: lift one tonne 100 metres, about 367,000 times. 🏗️ Energy = mass x gravity x height. Nature pays for the gravity. You pay for the mass and the height. Save this for the next "perfect" sales pitch. #LogicBeforeAI #EnergyStorage

Dyson grows strawberries on 5.5 m wheels. 🍓 Real engineering, 2025 trial. Dyson: 2.5x space "in the same footprint". The story: 2.5x vs "a regular outdoor farm". One is a test. The other is a weather report. 🌦️ Next "2.5x" pitch? We ask "times what?" 🔖 #LogicBeforeAI

DIY drone. Frame: two plastic rulers. 📏 It flies. The flight board is connected to a transmitter. The part plugged into the board is a receiver. Like labelling your inbox "Sent". Built is not ready: calibrate, test props off, register if above a certain weight. #Drones

This is how paint is made, then shows tinting: the last step. 🎨 A factory made the paint. One patent: a light base has room for about 2 oz of colour a gallon. By that logic, "how cars are made" is someone hanging up the air freshener. 🚗 Watch 👇 #ALlogic #Paint

Early airbag folding machine: about 40 seconds a bag. By hand: 12 minutes. ⏱️ In a crash, the bag opens in under 1/20 of a second. The clip says over 50,000 lives saved. A newer US estimate: about 70,000 by 2019. For once, the internet undersold it. #ALinsights #Engineering

PFAS clean-up has 3 steps: measure, remove, destroy. Imagine pitching your board that way. Revenue? Geese. Burn rate? Sunset. Profitability? Imagining. Step 3 is the hardest. Ask who tested it. 👇 #ALinsights #PFAS

Sugarcrete: blocks made with sugarcane waste.🧱 A lab sample: 4x lighter than dense concrete block. Best lab strength: 2/3 of a standard one. The pitch skipped strength. So a concrete block made 7.3 megapascals its LinkedIn headline. First question?👇 #ALinsights #Sugarcrete

A 3D printer at a party: "I am in teeth." "Oh, dentist?" "No. Never once met a mouth." 🦷 Dentures? No gum base. They look like bridges, from a dental lab. The printer makes the teeth. People make them fit. What work of yours never makes the video? 👇 #ALinsights #DentalTech

A bed in the middle of Baku's airport 🛏️ Pull the shade down and nobody sees your face. Your socks are now your headshot 😄 Cleaned after each use? No public answer. Comfort sells the first nap. Proof of clean sells the second. Would you nap here? 👇 #ALinsights #Travel

Brewery leftovers in. Animal feed out. The workers? Fly larvae 🪰 The 2024 plan: a franchise. Most send a manual and an apron. This one sends baby larvae. Your welcome kit tries to leave 😄 Once is a pilot. 100 times is a business. Bet on bugs? 👇 #ALinsights #AgTech

"World's first flying car"? The Aerocar flew ✈️ Alef's claimed first: driving down a street, then lifting straight up. Its road plan: about 25 mph max, so 8+ hours of driving per charge. One full charge is a full-time job 😄 Fly or drive? 👇 #ALinsights #FlyingCars

A bike with four wheels, a roof, doors and a back seat ☔ In law it is an e-bike: 250 W, assist to 25 km/h. In France, four wheels usually means no bike lane. It costs more than a Citroën Ami. For the extra money, you get cardio 😄 Would you ride one? 👇 #ALinsights #EBikes

Rescuers doing CPR swap about every two minutes. Our office handovers take a month and a cake 🎂 A CPR machine does not tire. Big trials: no more lives saved than CPR by hand. Its job: freeing hands where they struggle. What would you hand to a machine? 👇 #ALinsights #EMS

A startup claims gold from mercury at 10x a CERN record. At CERN's top rate, that is about a trillionth of a gram an hour. No yield or cost given. Around 1950, US scientists did the reverse: gold in a reactor, mercury out. For a lamp. What do you ask first? #ALinsights #Fusion

The space elevator does not have a cable yet. It does have some very beautiful drawings of the lobby 🛗 Designs assume 100 to 150 GPa. Best bulk nanotube fibre: 8.2 GPa. Watch the cable, not the drawings. What is the "cable" in your project? 👇 #ALinsights #SpaceElevator

A big coffee firm called CEE's roaster idea "too innovative," its makers say. Everyone wants innovation. Just in a small cup, with the lid on ☕ So they bought a roastery and let people taste the result. Cup or spec sheet? 👇 #ALinsights #Coffee

It looks like a railway. Officially, it is a road. 🚌 On Adelaide's O-Bahn, small guide wheels steer the whole bus for 12 km. In the suburbs, they are just passengers. One bus, no transfer, 40 years running. Watch 👇 #ALinsights #UrbanTransport

Most days this balcony railing holds laundry and basil. Turns out it is also a fire escape. 🏢 One lever, and each stair knocks open the one below: 13 floors in about 10 seconds, no power. Climbing down took about 5 minutes. Would you use it? 👇 #ALinsights #FireSafety
