The Gravity light !
Bringing light to Africa and India !
Watch this clip on The Gravity Light !
GravityLight is a revolutionary new approach to storing energy and creating illumination.
It takes only 3 seconds to lift the weight which powers GravityLight, creating 30 minutes of light on its descent. For free.
Following the initial inspiration of using gravity, and years of perspiration, they have refined the design and it is now ready for production. They need your help to fund the tooling, manufacture and distribution of at least 1000 gravity powered lights.
They will gift them to villagers in both Africa and India to use regularly.
The follow-up research will tell them how well the lights met their needs, and enable them to refine the design for a more efficient MK2 version.
To achieve this they launched a fundraising campaign on Indiegogo.

Asphalt Lake in Trinidad
The Pitch Lake is the largest natural deposit of asphalt in the world, located at La Brea in southwest Trinidad, within the Siparia Regional Corporation. The lake covers about 40 hectares and is reported to be 75 metres deep.
Although it wouldn’t seem like a bubbling lake of hot tar would be able to host life, we find out that it is teeming with microbial life.
In fact, each gram of sticky black goo can harbor up to 10 million microbes.
Pitch Lake is a tourist attraction that attracts about 20,000 visitors annually. It is also mined for asphalt by Lake Asphalt of Trinidad and Tobago.
Pitch Lake has fascinated explorers and scientists, as well as attracting tourists, since its discovery by Sir Walter Raleigh in 1595. Raleigh himself found immediate use for the asphalt to caulk his ship. Exported asphalt from Pitch Lake was also used to pave the streets of some regions of New York City. Since its re-discovery, there have been numerous research investigations into the use and chemical composition of this material. Above all, there have been countless theories, postulations, and conclusions as to the size, source, and origin of the asphalt.
The local Carib tribe believed that the pitch lake was created after the local tribe(who had just won a battle) feasted on hummingbirds, knowing that they were their dead ancestors. The winged god was furious and drowned the village creating the pitch lake. For the Caribs the pitch lake is a symbol of emptiness but today it’s a symbol of money.

The Ant Nebula !
Mz 3 (Menzel 3) is a young bipolar planetary nebula in the constellation Norma.
It is composed of a bright core and four distinct high-velocity outflows that have been named lobes, columns, rays, and chakram.
Mz 3 is often referred to as the Ant Nebula because it resembles the head and thorax of a garden-variety ant.
The Ant Nebula is 8,000 light years away from Earth and it has a magnitude of 13.8. It was discovered by Donald Howard Menzel in 1922.
A planetary nebula is an emission nebula consisting of an expanding glowing shell of ionized gas ejected during the asymptotic giant branch phase of certain types of stars late in their life. Planetary nebula is a partial misnomer that originated with astronomer William Herschel, because when viewed through his telescope, these objects appeared to be clouds (nebulae) that were similar in appearance to Uranus, the planet that had been discovered telescopically by Herschel. Herschel’s name for these objects was adopted by astronomers and has not been changed, even though planetary nebulae are now known to be completely unrelated to the planets of the solar system. Planetary nebulae often contain stars, but do not contain visible planets. They are a relatively short-lived phenomenon, lasting a few tens of thousands of years, compared to a typical stellar lifetime of several billion years.
