"If we were driving pure hydrogen automobiles, that automobile would actually help clean up the air because the air coming out of the exhaust would be cleaner than the air going into the engine intake"
About this Quote
The specific intent is persuasion-by-reversal. Weaver isn’t just advocating hydrogen; he’s trying to dissolve the psychological resistance that says “green” equals inconvenience. By focusing on exhaust, he targets the part of the machine the public already associates with guilt and smog. The subtext is that technology can redeem the very lifestyle it helped endanger, without demanding a cultural reckoning about consumption, urban design, or car dependence. That’s comforting, and it’s also the point.
Context matters: Weaver was a high-profile celebrity environmentalist who famously converted a vehicle to run on hydrogen and used his platform to evangelize cleaner energy. Celebrity activism works best when it offers a simple, vivid mental picture you can repeat at a dinner party or on a talk show. This line does that, while quietly skipping the messy middle - hydrogen production, energy sources, infrastructure, and the fact that “clean” depends on how the fuel is made.
It’s optimistic PR with a sly edge: if the air is already so dirty that a car could “clean it,” then the indictment isn’t subtle.
