Water-electrolysis toy cars / Mini hydrogen cars
Japan's Daido Metal, a manufacturer of bearing metals, has developed a fuel cell toy car that uses water as its source of hydrogen.
The Daido Metal toy car is using hydrogen created from the electrolysis of pure water. The car is 19cm long, 10cm wide and 8.5cm high, and weighs 350g with a full tank of water.
The Fuel Cell Toy Car will sell for 20,000yen.
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.
