Hydrogen Planes

Preventing Water Wars with Hydrogen Planes BOX Score

Hydrogen planes may be the best insurance policy against wars over water when the ice caps melt, and people panic from thirst and famine.

We treat public policy like puzzles to solve, searching for the highest nonpartisan scores, and talking about solutions like the big game it is.

This is a Politics 4.0, four-minute read.

The Puzzle

Countries bordering mountains that depend on the runoff to feed their streams will become desperate for water when the ice caps melt.

solution is to methodically convert all long-haul flights to hydrogen fuel, which would water the planet with the equivalent of one or two Lake Tahoes a year. The extra humidity will help refreeze the poles and re-snow mountain caps.

You can read more about it in our intro article. We go into sudden depth on the difficult-to-call roles in our Tiebreaker article. This week’s PolicyKeys puzzle can be found here. It’s a great team sport, especially in the classroom.

Aha Moments

(YES) because water is cheaper than war

(YES) because it helps avoid a billion climate refugees by 2050

(NO) because it will fuel even more green inflation

(NO) because hydrogen needs heavy investment


The US Public Policy Leaderboard (US-PPL) ranks solutions so ‘us people’ can keep track of what’s most important to the silent supermajority. Political parrots hate it when we think for ourselves.

Hydrogen Planes
Nonpartisan Score

POLI was slightly more optimistic than our editors. We predict a 71% ±4 (11 roles) STRONG SUPERMAJORITY of roles in this country to support HYDROGEN PLANES TO PREVENT WATER WARS, including a majority of each of the four sides of the political tablemaking this a US Public Policy Leaderboard (US-PPL) worthy idea. 

90% and up Near Unanimous
80% – 89% Near Consensus
75% -79%Vast Supermajority
60% – 66% Supermajority
50% – 59% Majority


SCOTUS’s approval rating is 41%,
the media is 32%, and
Congress is 15%.

Do we expect you to agree with the supermajority on all the rankings? 

Of course not; you’re human, not a hyper-partisan parrot.

We think you’ll agree with the leaderboard about 3 out of 4 items on average. Why?

The average score of the policies on the PolicyKeys™ US Public Policy Leaderboard (US-PPL) Sweet Sixteen is 76%, with many above 80%Politics 4.0 is already a 2x to 5x better model of US political sentiment and direction than politics as usual.
