Lamp powered by gravity – a truly frugal technology

I came across a description of a lamp that is powered by gravity recently, called GravityLight.  This lamp is powered by raising a weightCentriYes, and as it is then lowered over a period of 25 minutes it powers a LED light.  For people without electricity this is a really low cost way to have light during the night.

Technologies like this have the potential to make a real difference for millions of people.  That in itself is worth the effort to come up with solutions like this.  Millions of children do not do well at school because they do not have light at night to study.  And for many of us the experience of pitch black during the night is unthinkable, because we are surrounded by electricity and lights 24 hours a day.

In addition to that technologies like this also shine the light on a road often less traveled – to limit our use of resources in order not to deplete them unnecessarily.  By being a bit more careful we can save a lot of energy and decrease pollution.  We should make how much energy we use and waste we generate during manufacturing and also afterwards during operation of a new technology a design imperative rather than an afterthought.

Well done GravityLight – you really are a shining light.  We need more people in technology that think like you.

  1. I have been surfing online more than 4 hours today,
    yet I never found any interesting article like yours. It is pretty worth enough for me.
    Personally, if all site owners and bloggers made good content
    as you did, the web will be much more useful than ever before.
