A Japanese toy-company is shipping a water-powered, 19cm-long car that "uses hydrogen created from the electrolysis of pure water" to run itself. Link (via Engadget)
Steve sez: "this thing undoubtedly uses electricity to _produce_ hydrogen from water (that's what an electrolyzer does). The hydrogen is then converted back to electricity to run the car. In other words, this thing is nothing but an inefficient _electric_ model car. The coming 'hydrogen economy' has been oversold. Don't believe the hype!"
