In my childhood, I can remember my brother and his dynamos. He used it to power his toy cars. I am not really familiar with dynamos not until a great submission from Joan Rojeski disseny sostenible team to IGreenSpot was made. The group presented an eco-friendly lamp called the Lham Lamp. Looking at its photos, the lamp looks elegant enough to be in your modern home. You can have it used to both indoor and outdoor purposes. The lamp uses LED lighting technology and a dynamo for its power needs. With all these features and sleek design, tell me if this is not sustainable enough.
