Autonomous Rail Rapid Transit

Automated rail transit is an environment friendly, rail-less, and driver-less vehicle that is projected to reduce traffic congestion in the highly populated cities. On effective execution of this project, which is presently under development in China, is expected to gain extensive traction in the near future. Due to its low construction cost and a huge carrying capacity, road jamming can be reduced significantly. Additionally, no track is required for its operation, multi-axle steering system, and also functions effectively under extreme climatic conditions.

The world’s first driverless autonomous rail rapid transit (ART) system, equipped with sensors for the measurement of road dimension and also helps to create its particular route, under a test run in the city of Zhuzhou in central China’s Hunan Province. It was revealed in Zhuzhou in Hunan province on June 2, 2017 and is expected to be operational in 2018.

The product has been described as a combination of a train, bus, and tram. An ART train with three carriages is around 30 meters long and costs about US$ 2.2 million to construct. It can travel at a speed of 70 km/h and provides space for maximum 300 passengers and a five-carriage train can carry an estimated 500 passengers.

Rio de Janeiro turns garbage into energy

Rio de Janeiro, a city of about 6.7 million is also one of more than 70 cities worldwide that are aiming to become “carbon neutral” by 2050, meaning they will produce no more climate-changing emissions than they can offset by other means, such as planting carbon-absorbing trees.

From planting trees to promoting renewable energy and cleaner methods of transport, such as electric cars and buses, each city is going about achieving its carbon neutral goals in different ways, and with varying degrees of success.

Whirlpool provides energy to rural areas

This whirlpool can power a small village. It provides energy 24 hours a day. It can be installed in most streams and canals wherever a natural height difference occurs. It’s designed to bring electricity to rural areas and doesn’t require skilled labour to build.  Current technology is invasive and destructive but this device won’t harm the ecosystem.

How does it work?

It’s installed at a small,natural height difference. Land is excavated near the water. Prefabricated parts are installed, then the core of the turbine. The land is filled back in. Then the river wall is opened and the turbine starts working 24/7. The generator is the only moving part so it reduces the chance of failure.

This tech is being tested in rural areas and is producing promising results. It could energise the world over. What’s better than clean energy for all?

Space technology to predict droughts several months in advance

Scientists from ANU have used new space technology to predict droughts and increased bushfire risk up to five months in advance.

ANU researcher Siyuan Tian said the team knew they needed to move into space to get closer to understanding the complex nature of drought.

They used data from multiple satellites to measure water below the Earth’s surface with unprecedented precision, and were able to relate this to drought impacts on the vegetation several months later.

“The way these satellites measure the presence of water on Earth is mind boggling,” said Ms Tian from the ANU Research School of Earth Sciences.

“We’ve been able to use them to detect variations in water availability that affect the growth and condition of grazing land, dryland crops and forests, and that can lead to increased fire risk and farming problems several months down the track.”

The drought forecasts will be combined with the latest satellite maps of vegetation flammability from the Australian Flammability Monitoring System at ANU to predict how the risk of uncontrollable bushfires will change over the coming months.

Seabin: Rubbish bin for the ocean

More than 13 million tonnes of plastic enter Australia’s waterways every year, and some experts believe by 2050 there will be more plastic pieces in the world’s oceans than fish. Meet Seabin, a device designed to collect plastic waste floating in coastal areas before it gets to open water and breaks down into harmful microplastics.

Earthquake-resistant concrete

A new seismic-resistant, fibre-reinforced concrete developed at the University of British Columbia will see its first real-life application this fall as part of the seismic retrofit of a Vancouver elementary school.

The material is engineered at the molecular scale to be strong, malleable, and ductile, similar to steel—capable of dramatically enhancing the earthquake resistance of a seismically vulnerable structure when applied as a thin coating on the surfaces.

Researchers subjected the material, called eco-friendly ductile cementitious composite (EDCC), to earthquake simulation tests using intensities as high as the magnitude 9.0–9.1 earthquake that struck Tohoku, Japan in 2011.
