What's a Watt - Power benchmarks

VWEW's 'Lernsequenzen' (in German) [1], gives a few typical power benchmarks, allowing to develop an intuitive feeling for Watts, from mili-Watts and Megawatts:

• Wristwatch: 0.02 mW
• Bicycle light: 3 W
• Person (continuous): around 100 W
• Top sport (long-duration effort): around 340 W
• Average power of a horse: around 500 W
• Car: e.g. 55 kW
• Truck: around 250 kW
• Diesel locomotive: up to 3,000 kW
• Nuclear power plant: 1,300 MW
