GravityLight: From Gravity To Light

From Gravity To Light

gravity light power electricity


Providing clean energy

Because a lot of poor people don’t have access to electricity (and thus light) lot’s of them still use kerosene lamps to light their home. The team from GravityLight.org made this innovative solution for this problem. It not only provides light, but also gets rid of the unhealthy burned kerosene fume.

From potential to kinetic energy

GravityLight is a solution to provide light using gravity. Just like an old clock, you pull up a 12 kg weight and it slowly starts falling down (about 1mm / second). This movement powers a drive sprocket. A geartrain running through the product turns this input into a high speed, low torque output that drives a DC generator at thousands of rotations per minute.

This generates just under a tenth of a watt to power an onboard LED and ancillary devices. Given the ever-increasing efficiency of LEDs, this produces a light over 5 times brighter (lux) than a typical open-wick kerosene lamp.

Electric Aircrafts

  • e-one electric plane with solar panels

My last post about small electric cars showed different innovations in electric urban vehicles. This also counts for electric airplanes. There has been a huge leap forward in batteries, battery management and (brushless) electro engines for airplanes. This makes it possible to design and produce (clean) aircrafts with an already impressive range.
In this post a small overview of different producers, from DIY to scientific ‘around the world’ project, from glider to James Bond gadget.

Gallery: Electric Trikes / vehicles

  • Toyota announced the i-road

Last weekend I was in Antwerp, Belgium. The city centre was closed for car traffic to promote alternatives for clean urban transport. One of the solutions were these ‘reverse trike electric vehicles’. In the gallery above a quick view of different solutions that can be purchased nowadays. From DIY to James Bond like gadgets. Advantages:

  • Clean and Electric
  • Small ( 1 / 2  persons)

What do you think, can this be a clean solution for urban transport?
