Hydrogen & Future Fuels
Fact-checks and plain-English explainers on hydrogen, HHO claims, and the fuels that come next.
Can a Car Really Run on Water?
No — water is not a fuel. Splitting water into hydrogen takes more energy than burning the hydrogen returns. Here's the physics, and what the claims get wrong.
HHO Kits Explained: What They Do and Why They Don't Save Fuel
HHO kits electrolyze water into hydrogen-oxygen gas using your alternator. Testing shows no fuel savings — the electricity cost exceeds any combustion benefit.
Hydrogen Car vs Electric Car: Which Technology Actually Wins?
EVs beat hydrogen cars for personal driving: 3x better energy efficiency, vastly more fueling infrastructure, and lower cost per mile. Hydrogen fits heavy transport.
