Come on down to the Slush Puppy Place, in Kingston on Saturday morning. I'm giving a live show for kids, showing them how they can extract DNA in their own kitchen using ingredients that they probably have already in their cupboards. Come learn about DNA!!!

Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004. Today, building a fence with solar can be cheaper than using wood.

🔥Performance Under Pressure 🔥 Today, we're pushing Mosaic’s PEEK material to the limit—testing its ability to self-extinguish when exposed to direct flame and extreme heat. Curious to see the performance firsthand? Request a sample part from our team: hubs.la/Q03rwPqP0

New tech scales way faster than old. Solar went from 100 → 1,000 TWh in 8 years, then doubled again to 2,000 TWh by 2024—in just 3 more years. For each of the last three years, solar was the biggest source of new electricity globally. Nothing else has scaled this fast.

1 billion people in Africa still cook with basic fuels like wood, charcoal & dung, contributing to over 800,000 premature deaths a year – mostly women & children. Solving this major injustice would cost less than 0.1% of global energy investment. More 👉 iea.li/3GUewI1
