Lift Challenge

This is being announced to us or everyone right now? It's only around 10 weeks away: that seems surprisingly close. Have some folk already been made aware & have they had time to build for this DARPA Challenges? Generally I think of them as longer running challenges.

Darpa.mil got slashdotted? Wow. The folks who invented the internet...

The military is waking up to the need to adapt frontline logistics. With killrates of 90% for traditional trucks in the Ukraine war, without resupply missions by UAVs/UGVs holding positions is impossible now.

Really just a battery challenge. Possibly against laws of physics at energy density of 4x?

> Competitors must create an aircraft that is both lightweight and powerful – lifting at least 4x its weight while flying a 5-nautical-mile circuit course. I'd make it 50NM. 5 is way too easy to bullshit with edge case engineering. Alternatively, set a minimum payload capacity of something like 100kg.

CATL is working on 12000 Wh/kg air batteries, they will solve this problem, give them the prize.

Been working this for a few months now. It’s not a crazy hard problem - but it does break the mold of distance and speed taking priority over capacity. If you have any questions feel free to ask. I can get into the pros/cons of all the various options and tuning knobs.

Hate that "warfighter" has entered our vocabulary. It's so kitsch...
