## 2 thoughts to “Energy Forms”

1. Infrared energy is a hidden glowing energy that is commonly present now on most household devices such as heaters. You can now find the best infrared heater available in the market in several sizes and different brands. Everyone can now experience a more efficient and eco friendly heater, thanks to the power of infrared energy.

1. Thanks for the comment. In this case we want to maintain an educational focus rather than a commercial focus.
