...have made cloud seeding commercially viable. From small startups.
So, in steps a tech entrepreneur: Augustus Doricko. The founder of Rainmaker.
I'm not an investor; I have no relationship. I want to call attention to their work as I've suffered through wildfires myself (twice).
There are four steps to Rainmaker's tech and how cloud seeding works:
1. Disperse tiny droplets of silver or potassium iodide into clouds.
Why?
In nature, similar droplets organically disperse into clouds—airborne atmospheric elements such as soil, dust, ash, sea salt, or pollen.
With silver or potassium, we're mimicking those effects in an on-demand, scalable way.
Step 2: The cloud's water molecules naturally coalesce around these newly-introduced agents.
At first, due to the hydrophilic effect: the natural attraction of water molecules to one another because of their charged polarity.
Then, driven by random collision-coalescence:
Now for step 3: The newly formed tiny water droplets (or ice crystals) continue to bond and merge into even heavier droplets.
As these merge and grow, the cloud's upward air currents can no longer counteract gravity to keep the droplets suspended in air.
Onto the last step.
Rain (or snow) starts when droplets grow to ~40 microns, breaking free from the suspending air currents and finally falling to Earth.
This process of "cloud seeding" requires very little silver iodide:
A 6oz glass (3/4 of a cup) can trigger rain over *hundreds of square miles.*
So, it's not crazy expensive.
Rainmaker disperses their cloud seeding agent using...
weather-resistant drones!
Combined with numerical modelling to accurately predict weather and advanced radar to verify real-time conditions.
It’s not overly complicated to pull off.
The barrier is government approval and even more work to affirm safety.
The combination of these technologies unleashes a new age of weather modification in America.
Something that China is already doing on a huge scale.
California reservoirs are running out of fresh water.
Variable crop yields put pressure on inflation.
Extreme weather leads to untenable insurance claims.
The time for proving the safety of wide-scale adoption of weather modification is probably now.
At , my seed fund, we invest in crazy futuristic tech like this. Please reach out so we can chat and help you with growth if we invest.Julian.capital
Crucially, we also created to help ambitious hardware & science startups get funded by many deeptech VCs—not just us. It's the biggest site of its kind. And it's free.

i finally did it! i eliminated all mosquitos. haven't seen one in ages
the technique:
- fill buckets with water, dirt, grass
- place buckets in shade, spread 50ft apart
- put a "mosquito dunk" ($0.50 each) in each
- wait 6 weeks
that's it!
it works because...
mosquitos like to lay eggs in stale water. that's why you put dirt and grass in the buckets—to produce "old water" chemical reactions for them to sense. they like stale water because it's likely to remain, which means their eggs can hatch
now, you see that donut thing? well...
that mosquito "dunk" contains a harmless-to-humans bacteria that kills eggs once laid
as long as you have no other sources of stagnant water on your property (first address that), they have nowhere else to bread but in your buckets
