What we do

  • Abretech invents and creates new types of energy-related equipment that will…
    – Cut the need for fossil fuels
    – Reduce climate change
    – Provide these devices cheaply to the world so even poor people can enjoy the benefits.
  • After we launch the Koomidown (probably 2017) we hope to offer new kinds of batteries for electric bicycles and for powering homes.
