I have had a kickback ripping 2x4s on a table saw when in a professional woodshop with my dad. That one luckily didn't cause me any injury, but my paychecks from my summer job for the next two summers went directly to the woodshop owner to pay for the damages. The 2x4 flew with such force from the saw that it hit a shelf of tools behind me, destroying several and deflecting slightly before going THROUGH the side of the building, which was a steel shop building from the 60s. Just imagine what it would do if you'd been standing there. You always see those pictures of a hurricane taking a piece of grass and embedding it into a telephone pole, well a table saw can take a 2x4 and put it through just about anything. Crazy powerful tools.

The reason people don't think it's because in their mind they don't understand a Watt is. Your average gasoline gallon has 33kW worth of energy in it, which can drive your car for about 35 miles or around 1kW / mile. Look at your average table saw running at 600W of consumption and consider that piece of hardware is using up enough power to move your 3000 pound car a little over half a mile.

  > ...gasoline gallon has 33kW worth of energy in it... kW are a unit of power (energy/time, 1 W = 1 Joule/s), which is not relevant to measure energy content (for a gallon of gas). You'd want plain Joules for that.
