text: Yo, check it out, I got a story to tell
  'Bout portable devices and how they fell
  They run out of juice, can't keep up the pace
  But I got a solution that'll rock the place
  
  Listen up, this paper's got the scoop
  An alternative power source that makes you loop
  We convert your walk into electricity
  From the soles of your shoes, it's pure simplicity
  
  We got air bulbs in the game, distributed just right
  Harnessing the power, day and night
  Micro-turbines and DC motors in the mix
  Optimized to harvest the airflow, that's the fix
  
  We keep it flowing, no time for rest
  Outflow, inflow, it's the best
  Designed for continuous power, it's a thrill
  No need for batteries, we got the skill
  
  Put on a combat boot, test it out
  75 kg subject, no doubt
  Walking at 3.0 mph, feeling fly
  Average power of 10 s of mW, oh my!
  
  Over a 22 Ω load, it's no joke
  Enough to power a GPS tracker, that's the stroke
  Relaying coordinates to your phone with ease
  No battery replacement, we aim to please
  
  So next time you're walking, feeling the beat
  Remember this device, it can't be beat
  Power in your steps, energy on the go
  Turn your walk into electricity, yo!
