Rasputin has good critical thinking skills and is right when he/she is concerned with the inherent give and take of energy production. However, he/she also has a poor understanding of physics involved in this situation. Rasputin and Paul’s criticisms are unfounded and based on faulty logic.

First of all, we do not know to what extent the Piezo or Heel Strike Generators give. How much do they move? Many items we use every day move as we touch them, yet seem not to take any extra energy output – typing on a key board for example. Using Rasputin’s logic, typing this response to his post should be considered a workout and make me hungry. So the claim that these tiles would create more need for food is unfounded.

Second, walking down stairs created a greater impact than our bodies need, it’s called gravity. That’s why we have nice soft soles on our shoes. Adding soles to our shoes does not make one extend a significant amount more energy when walking, but it is better for our joints. Which is better for one’s body in the long run. Which helps with doctor’s visits and keeps health care costs down.

So, Rasputin and Paul, try to be more open to the exciting, creative, and efficient new ways people are exploring to create essential electricity and I’ll try not to make you look like a fool on the internet.

So instead of just getting power from the grid, they are taking power from the grid, using it to run tractors and pump water, growing food, having it consumed by lots of humans and then walking them on pressure plates? Extremely inefficient. Apparently ‘the future’ is people making showy, expensive, inefficient inventions to generate paltry amounts of electricity…
