@sierrap Lots of GPs offer to make intros to LPs, few follow through with any. I think you made 12 introductions for me! I'm grateful for you trailblazing the path with @VoyagerVC and for all your help with this fund Now we just need to find an investment together

The world is getting warmer while our infrastructure gets older: a recipe for disasters. We’re excited to announce Fund II: $85M for early stage investments in disaster resilience.

We have a shortage of urea again. The last time I saw this was during the pandemic. We need to come up with better ways to produce fertilizer. Who's working on this?

“You can see the surface of the Moon…we just went sci-fi.” On flight day seven, images from our @NASAArtemis II crew amazed, turning science fiction to reality. From the lunar far side to a solar eclipse from the Moon, the views are EVERYTHING. No pressure to pick a favorite.

Senator Mark Kelly@SenMarkKelly·
"A whole civilization will die tonight” are words no President of the United States had ever spoken until this morning. Donald Trump’s behavior is unhinged and making Americans less safe. After a 25-year career in the United States Navy, I have never met or served with anyone who so completely lacks the qualities of good leadership as Donald Trump does. If the President takes the actions he has threatened to take, countless Iranian civilians will die, it will massively escalate this war, and the United States will be seen as a country without a moral or ethical compass. That will make Americans less safe right now and risk the lives of thousands of service members. The consequences will have a lasting and damaging effect on our nation. Trump's mistakes have led us to this perilous moment, but the solution is not to escalate even further. This must stop.

@tferriss 9/10 - Good navigation of spaces and furniture; effective in both vacuuming and mopping. Only complaint: not silent.

Has anyone used Matic (robot vacuum)? If so, from 0-10 (no 7 allowed), how strongly would you recommend and why? Thanks! 🙏

We could just... stop. This is such a waste of resources, land, and nitrogen. Even if we still wanted to use this land for fuel, we should be planting perennial grasses that require no fertilizer or irrigation and can yield far higher dry biomass per acre for use in Fischer-Tropsch (biomass to liquids) or gasification plants.

Effectively all growth in corn production over the last 20 years is for ethanol. ~20 million acres of conservation land, grassland, and soybean rotation was turned into corn monoculture that effectively strip mines the topsoil. Meanwhile it’s the most fertilizer dependent crop with only a 40% uptake rate. So ~1.7 million tons of nitrogen runoff flows into the Mississippi basin annually while also polluting their own water supplies. This runoff ends up expanding the Gulf deadzone, which is also where 40% of domestic seafood comes from. It’s hard to find a worse way to create fuel, with a wicked level of waste and downstream consequences.

ProPublica spoke to dozens of people who’ve worked on U.S. immunization programs. They shared a pit-of-the-stomach dread that future American children will fight for their lives against infections that have long been preventable. propublica.org/article/rfk-jr…

Gotta be honest: not great that paying data centers to turn off is our plan for grid reliability through 2030. A curtailment payment? Come on. This is bad! We have to stop managing the failure and build the grid we should have built in the first place. What are we doing here?!
