Deep Learning Technology Predicts Accidents on The Road

Posted by in categories: mapping, robotics/AI, satellites, sustainability

Studies say that by combining historical accident data with road maps, satellite imagery, and GPS, a machine learning model is trained to create high-resolution crash maps, we might be getting ever so closer to safer roads. Technology has changed a lot over the years such as GPS systems that eliminated the need to memorize streets orally, sensors and cameras that warn us of objects that are close to our vehicles, and autonomous electric vehicles. However, the precautions we take on the road have largely remained the same. In most places, we still rely on traffic signs, mutual trust, and the hope that we’ll reach our destination safely.

With a view to finding solutions to the uncertainty underlying road accidents, researchers at the MIT Computer Science and Artificial Intelligence Laboratory have been working with the Qatari Center for Artificial Intelligence to develop a deep learning model that can predict high-resolution maps of accident risks. The model calculates the number of accidents predicted for a specific future time frame using past accident data, road maps, simulations and GPS traces. Thus, high-risk zones and future crashes can be identified using the map.

According to reports by homelandsecuritynewswire.com, maps of this type have been captured so far at much lower resolutions, resulting in a loss of vital information. Former attempts have relied mostly on hystorical crash data, whereas the research team has compiled a wide base of critical information, identifying high-risk areas by analyzing GPS signals that provide data on traffic density, speed, and direction, along with satellite imagery that provides data on road structures. They observed that highways, for example, are more hazardous than nearby residential roads, and intersections and exits to highways are even more dangerous than other highways.

T-Omega re-thinks floating offshore wind turbines for huge cost savings

Posted by in categories: energy, sustainability

Most of the world’s greatest wind power resources are offshore – often a long way offshore, where the water’s so deep that it’s impractical to build typical fan-on-a-stick wind turbines with bases sunk deep into the sea floor. Floating wind, at this stage, is so vastly expensive to build, deploy and maintain that it ends up costing two to three times as much per kilowatt-hour of energy as fixed-bottom offshore installations.

There’s a huge opportunity here for technological advancement, and companies like Norway’s World Wide Wind are proposing some pretty radical ideas in the space. A lot of the energy cost comes down to the size, weight and materials involved in the structure of the turbine, along with the logistical issues and specialized equipment needed to build, install and maintain the things.

Scientists Discover Plastic-Eating Worms That Digest Styrofoam

Posted by in categories: biological, food, sustainability

Humanity has left its mark on the Earth, from cities of steel to mountains of styrofoam. The latter is proving to be a problem, as many of the synthetic materials we produce don’t degrade in anything approaching a human timescale. Scientists have long sought to develop better plastic recycling methods, and the answer might be crawling around in the wild. Researchers from the University of Queensland in Australia say that a beetle larvae (it looks like a worm in larval form) may hold the key to eliminating polystyrene from the environment.

Styrofoam, technically known as polystyrene, is one of the most common types of plastic, accounting for 7–10 percent of all the non-fibrous plastics produced. You probably encounter it frequently in packing materials where the material’s foam conformation is adept at absorbing impacts. The solid version of polystyrene can be used to make transparent containers, disposable utensils, and more. However, polystyrene carries a recycling ID of 6, meaning it’s difficult to process and is not accepted at most curbside pickups.

Scientists have long searched for microbes or insect enzymes that could help break down durable plastics like polystyrene, and a beetle known as Zophobas morio might have it. It’s a species of darkling beetle, and the larval form is more commonly known as a superworm. They look like larger mealworms and are often used as a food source for insectivorous animals. In addition to being a high-protein, low-carb snack, this creature’s gut carries a unique mixture of bacterial enzymes that can digest polystyrene. The researchers reported that darkling beetle larva can subsist entirely on a diet of polystyrene — they can even grow while eating a pile of plastic.

Dubai will be home to the world’s largest net-zero carbon urban tech district

Posted by in categories: climatology, education, employment, sustainability

The new district will create over 4,000 jobs.

Architectural practice URB has been commissioned to engineer the world’s largest Urban Tech District along the Al Jaddaf Creekside in Dubai. “Rising population, urbanization and impacts of climate change are increasing the need for cities to be resilient, liveable and smart. Thus the creation of sustainable cities is no longer a choice, it has become a necessity. This requires planners with experience in designing and delivering sustainable communities,” says URB on its website.

The new construction will join the global transition towards achieving net-zero carbon goals and become home to top-tier entrepreneurs, establishing Dubai as an urban center for innovation and empowering a unique tech ecosystem to unfold in the emirate and across the world. It will also feature several commercial and educational facilities. population, urbanization and impacts of climate change are increasing the need for cities to be resilient, liveable and smart.

Scientists Just Made Hydrogen Fuel With Nothing But Air and Solar Power

Posted by in categories: climatology, particle physics, solar power, sustainability

Even in the driest climates, though, there is a considerable amount of moisture in the air. The researchers note that even in places like the Sahel desert, relative humidity is still around 20 percent on average. So they set about finding a way to use this untapped water resource to produce hydrogen.

Their device consists of a water harvesting unit that houses a sponge soaked in a water-absorbing liquid that can pull moisture from the air. On either side of this reservoir are electrodes that can be powered by any renewable energy source. When a current runs through the circuit, the water is split via electrolysis into its constituent oxygen and hydrogen atoms, which can then be collected as gas.

The team showed that the device could run efficiently for 12 consecutive days and produced hydrogen with 99 percent purity. What’s more, the device continues to work in relative humidity as low as four percent.

Elon’s Real World AI is the Real World Technological Singularity

Posted by in categories: economics, Elon Musk, employment, mobile phones, Ray Kurzweil, robotics/AI, singularity, sustainability, transportation

Ray Kurzweil predicted Technological Singularity nearly 20 years ago. Elon Musk could enable a world of economic abundance with real world AI. Robotaxi and Teslabot will transform the world more than car and the first industrial revolution.

Tesla sells Model Ys for about $60000, but it currently costs them about $30000–40000 to make them. A Teslabot is 1/30th of the mass of a Model Y. It will use 1/30th of the batteries. The software is an overall cost of development. If billions of bots are produced then the cost would trend toward the cost of the hardware plus Apple iPhone-like margins including the software (say 40% gross margin). At Model Y cost of $30k then the hardware cost for Teslabot will go to $1000. $2000 with margins and software. A bot can work for 8,000 hours in a year. 8,760 hours in a year. $2000 divided by 8,000 hours is $0.25. If you add 10 cents per hour for electricity then it is $0.35 per hour. Going beyond that is bots can work in the factory and work cheaper than humans. Currently 15,000 workers in Tesla China factory. Replace all of them with $0.35 per hour bots. Reduce labor cost component. If a lot of bots can increase production rates. by 2X then all costs spread over more units. Bot-produced solar and batteries can lower the cost of energy by vastly increasing the supply. Those trends could get us to $500‑1000 per bot costs and lower energy costs. Having virtually unlimited labor costing less than 35 cents per hour will be transformational.
