Photographer constructs drone to capture wildlife in the Serengeti

The British photographer Will Burrard-Lucas built a drone at home to capture the incredible wildlife of Serengeti, Africa. Powered by six mini-motors, the drone can fly up to 15 minutes at a time, allowing the Burrard-Lucas plans so far unexplored by his colleagues.

The British managed to "catch" the hunt of the hyenas, wildebeest migration and the Hippo bath through a camera GoPro Hero3 +. Burrard-Lucas says that this technique is perfect for photographing the animals without scaring them off or put his own life in danger â€" still, we have some doubts.

The photographer, who lives in Tanzania, managed to control the drone about a mile away, also using a live video and a remote screen. According to press reports, the drone was mounted in five months.

"Animals react differently to the drone. The large animals do not see what comes from the air as a threat, since predators are terrestrial. The Hyena that I picked up was relaxed, just smelled the drone, "explained Will Burrard-Lucas.

The brand was recently launched on the market â€" at the end of last year â€" at the hands of Marco Salinas.

"It can be said that this project was born a chance. One day, while browsing the internet, I discovered that already manufactured bamboo sunglasses and I fell immediately by the concept and the beauty of these glasses, "said Marco Santos to GreenSavers.

Follow to Booglasses Facebook.

Quickly this entrepreneur found that his glasses were a bamboo covered as yet unknown in Portugal and even in the rest of Europe, "where are the fingers of one hand the countries where there are these types of sunglasses". "Only in the United States, Brazil and Australia there are some brands on the market implemented. And quite successfully ", indicates.

The Booglasses are made entirely of bamboo, which has special advantages and ecologically positive: the strength and flexibility of the material and the strength/weight ratio. In addition, bamboo is a plant that grows more quickly, and may, in some cases, grow up to a metre a day. this way, bamboo can be used as a raw material without jeopardising the sustainability of species.

The glasses are manufactured manually, but not in Portugal. This is because, after a market research, Marco Salgado hasn't found who could manufacture the glasses in the country.

"We have acted in the main vectors of consumption of a park â€" the lighting and ventilation. This Park has natural ventilation, so the energy consumption associated with it is null. The facades receive natural light, so we can, through a lighting management system and regulation of flow of lighting, artificial lighting control, "explained to the green economy Pedro Laurel, of Galp.

The bet on efficient lighting and natural ventilation allowed reduce energy consumption by 30%. Before, the monthly bill came to € 1,800. 144 were also installed photovoltaic panels, which help reduce the electricity bill and prevent the emission of 300 tons of carbon dioxide. The panels also allow upload about 1000 electric vehicles per year.

Los Angeles: jaywalking is more expensive to park illegally

Los Angeles is repressing passersby that circulate in the city illegally, particularly those that cross roads outside the walkways or when the signal is red. However, the fines applied to these transgressors are heavier than those applied to drivers who do not respect the code.

The cheapest ticket for parking in prohibited places in this Californian City is €42, and the most common one is €53. Comparatively, cross a street illegally â€" an "art" that is already known for "jaywalking" â€" can cost €144, referred to Quartz.

The effort that the authorities are doing to punish violators legally is a reaction to the revitalization of downtown Los Angeles, which brought more people into the streets without their cars. The problem is that the city was built for cars and not to passersby.  In fact, the "jaywalking" is encouraged by the automotive industry, that by making the streets dangerous for passersby benefits from an increased demand for automobiles.

As the buried skeletons influenced the construction of the London underground

Yesterday, we wrote here that archaeologists have discovered a number of skeletons in the expansion works of the Mexico City metro, leaving on standby to new infrastructure and molding, perhaps, the location of future seasons.

The phenomenon, however, is not restricted to Mexico City. In London, according to the book Necropolis: London and Its Dead, the construction of The Tube-one of the most amazing and complete metro systems in the world â€" was highly complex. Due in part to the large amount of skeletons that the soil is home to London.

According to the author of the book, Catharine Arnold, the city is completely full of bodies, improvised cemeteries and wells created during the time of the black death. These eventually influence the location and construction of metro stations.

The author also gives a clear example of the difficulty with which planners and engineers found themselves in the middle of the 19th century, when the construction of the subway and ripped solidified its expansion. There is a clear change of direction on the Piccadilly line, East of South Kensington. "Actually, the curve tunnel between Knightsbridge and South Kensington stations because it was impossible to stick to the mass of skeletons that remains buried in Hyde Park," explained Arnold.

In other words: the soil is so dense, due to the interconnectedness of the skeletons of victims of the great plague in the 17th century, that the excavation teams from The Tube, 200 years later, failed to even enter this land.

The metro bypasses to avoid this incredible congestion of skulls, legs and arms attached to the ground â€" an artificial geology made from people. Interestingly, after all this time, as the city was molded to the expansion of the metro, to buildings built later, and how it all broke the decisions taken for several centuries.

In short: urban planners from 200 and 300 years â€" as well as decision-makers and public hygiene authorities-unintended London's current influencers were. You can meet other histories of the book here.
