Building a Network of Tunnels Underground to Ease the Flow of Traffic

Guest post by Aron Alba

“Roads must go 3D” – Elon Musk

The Boring company plans to build the network of tunnels under the ground in order to combat traffic congestions all over United States. As seen in their presentation video, the idea is to construct a system of tunnels in which electric vehicles autonomously zip around cars, people and cargo transport in high speed under the surface (like a scene from a science fiction movie).

The ride would begin with the lift that lowers the vehicles from the surface into the tunnel system. These lifts could be a possible bottleneck for the entire system, but it may be the best solution. To secure the vehicle to the autonomous pod and possibly select the end destination would take some time anyways, so this transition into the tunnel system could go unnoticed. Pods could travel at higher speeds than those allowed for the human driver, since the system is autonomous and completely monitored. The scenery wouldn’t be much though, so probably not the most interesting ride, but certainly fast.

Why build a tunnel network in the first place?
Traffic congestion is a very common nuisance in american lives. With the problem just getting worse. In order to solve this problem you have to build more roads or have fewer cars on them with arranging a better public transport. The land for the roads is scarce. The alternative of going up using drones to fly people around may not become possible due to safety concerns in a long time. Where to go then? Underground.

This has not been done before for obvious reasons, it is really expensive. The most expensive roads to build are tunnels and bridges. Tunnels have even more problems the larger they get. With people driving inside of them there needs to be proper ventilation to get rid of the carbon-monoxide. Resting stops for people. Great deal of risk with so many people driving inside a closed tunnel. The subway system is one solution to many of these problems. Except subways lack the flexibility and require substantially more infrastructure.

Elon Musk’s big plan is to use the technology that his other company Tesla already has developed. Instead of trains like in a subway system, Musk plans to have autonomous pods that run on battery power to zip along the tunnels. This has several advantages. First the battery powered pods to not require power lines to be continuously run through the tunnel like the train does, this saves on the costs of the tunnel. Also since the pods will be autonomous, this saves on personnel needed to operate the system. But probably the smartest idea behind the Boring company’s plans is to build a tunnel with a smaller bore diameter. Probably large enough to fit a pod with a largest planned Tesla vehicle but certainly smaller than the current tunnels for trains.

The Boring company plans to build the tunnel network using a tunnel boring machines. These machines are massive systems build to bore tunnels with circular cross section. They consist of cutting head system, a system for removing earth, systems for advancing the cutting head, systems for laying the concrete walls around the bore. At the end these machines leave a tunnel pretty much ready to use.

Drone Deliveries to Hospitals in Rwanda

Partnering with the Government of Rwanda, Zipline serves 21 hospitals nation-wide. They provide instant deliveries of lifesaving blood products for 8 million Rwandans.

Their drones are tiny airplanes (instead of the more common tiny helicopter model). Supplies are delivered using parachute drops from the drone. Landings are similar to landings on aircraft carriers (they grab a line to help slow down the drone) and, in a difference from aircraft carrier landings, the drone line drops them onto a large air cushion.

Zipline Muhanga Distribution Center launched in October 2016 making Rwanda the first country to integrate drones into their airspace and to begin daily operations of autonomous delivery.

As of May 2017, Zipline had completed over 350 delivery flights to real hospitals and their pace is accelerating. Zipline can cut delivery time from 4 hours to 15 minutes (which is extremely important in time critical health care emergencies).

I wrote in 2014 about the huge potential for drone delivery of medical supplies. It is wonderful to see Zipline improving people’s lives with their effort.

Small Farm Robots

The IdaBot was created by researchers at Northwest Nazarene University (Idaho, USA).

Using robots in farming is limited today but the future could see a huge growth in that use. Benefits of introducing more robots to farming include reducing the use of pesticides and chemicals to control weeds.

Reducing labor costs is also a potential benefit but at current market prices (due to high costs of robotics and available cheap labor) that is more something for the future than today. However that can change fairly quickly – as for example the collapse in solar panel costs have made solar energy economically very attractive. In areas with high labor costs (Japan etc.) or areas where there are active efforts to reduce the supply of labor (in the USA where a significant portion of labor does not have proper visa to work in the USA and the current administration is seeking to reduce that labor availability) robots become more attractive economically.

Robot farmers are coming to a field near you

In Japan, using robots to harvest strawberries is roughly cost-equivalent to human labor if the ‘bots are shared between multiple farms, Lux Research said.

“With strawberry-picking being slow and labor-intensive, and labor scarce and expensive ”” the average agricultural worker in Japan is over 70 years old ”“ the robot is quickly likely to become the cheaper option,” it said.

Lux Research also forecast European lettuce-growing ”” a major industry on the continent ”” would become automated by 2028.

“Automated lettuce weeding is already competitive with human labor in Europe, thanks to regulatory limitations on agrochemicals. Lettuce thinning is still accomplished manually at lower cost, but robots are likely to reach breakeven with human labor in 2028,”

The global market for agricultural robots will explode to $73.9 billion by 2024, up from $3.0 billion 2015

14 Year Old Signs $700,000 MOU for a Drone to Detect and Defuse Land Mines

Harshwardhan Zala, from Gujarat, India has signed an agreement worth Rs. 5 crore (US$733,940) to explore the possibility of commercial production of a drone created by him which can help in detecting and defusing landmines.

Harshwardhan started work on the prototype of the landmine-detecting drone last year after reading in newspapers about high army casualties due to landmines. Aerobotics7 is the company founded by the 14 years old.

Explaining more about the drone, the zealous 14-year-old said, “The drone is designed to send out waves that cover eight sq. mt area while flying two feet above the surface; the waves detect land mines and communicate their location with a base station. The drone also carries a bomb weighing 50 gram that can be used to destroy the landmine.” Harshwardhan Zala”™s proud father Pradhyumansinh is an accountant with a plastic company in Naroda, and his mother Nishaba is a homemaker.

The video has Harshwardhan speaking a bit of English but mainly some other language that I don’t understand. If I understand right, his drone is 98% accurate at identifying mines (where the current solutions are 92% accurate – and much more dangerous for those having to walk around testing). His solution is 17 times faster and 22 times cheaper than the current solutions. Once the mine is detected by the drone through an infrared sensor, a 50 gram detonator will complete the task of defusing it (blowing it up).

Autonomous Delivery Robots Launched in Europe and USA

Starship Technologies is launching a fleet of autonomous delivery robots on the pavements of the United Kingdom, Germany and Switzerland as part of the testing program. A similar program will be announced for the United States shortly.

The largest European food delivery company Just Eat, leading German parcel delivery company Hermes, leading German retailer Metro Group, and innovative London food delivery startup Pronto will test the delivery robots developed by Starship Technologies, a company launched in 2014 by Skype co-founders.

As part of the program, dozens of robots will be deployed in five cities to run first test deliveries and introduce the innovative devices to the general public.

“By launching partnerships with major companies we will enter the next phase in our development. While Starship has been testing the robots in 12 countries in the last nine months, we will now develop know-how on running real robotic delivery services,” said Ahti Heinla, co-founder, CEO and CTO of Starship Technologies.

Robots developed by Starship Technologies are meant for delivering packages, groceries and food to consumers in a 2-3 mile radius. The robots can drive autonomously while being monitored by human operators in control centers. Introduced to European and American cities since the end of last year, the robots have already driven close to 5,000 miles and met over 400,000 people without a single accident.

Frank Rausch, CEO of Hermes Germany, said: “We are very proud to be Starship”™s exclusive logistics partner in Germany. At Hermes we believe that parcel delivery”™s main goal is to fully satisfy the customers”™ needs in receiving their online shopping orders as fast and convenient as possible. Nobody likes to spend hours waiting for the courier just to have a parcel delivered. Therefore, individually scheduled delivery services will become increasingly important within the coming years.”

The test programs will run in London, Düsseldorf, Bern and another German city to start, before moving to several other European and American cities. Starship Technologies will also continue testing in Tallinn, Estonia where its R&D facilities are located.

Sustainable Ocean Farming

Farming the Sea: why eating kelp is good for you and good for the environment

There are serious problems with our ability to grow healthy food for the number of people we have today (and will have in the future). Innovations have allowed us to feed ourselves. But the damage done to topsoil and other damage including pollution of our rivers is huge. Overfishing and factory farms are keeping us going today but are doing immense damage and are not sustainable.

Seed companies abusing the corrupt government patent systems creates even more damage. We need better solutions. We have many people doing great things but we need to do much more. Ocean farming is one of many areas we should expand. And we should greatly reduce the use of factory farms, antibiotics for livestock, overfishing and the overuse of pesticides.

How an Army of Ocean Farmers are Starting an Economic Revolution

So we all went on a search for sustainability. I ended up in Northern Canada on an aquaculture farm. At that point aquaculture was supposed to be the great solution to overfishing, but when I got there I found more of the same, only using new technologies to pollute local waterways with pesticides and pumping fish full of antibiotics.

I never thought climate change had anything to do with my life. But it does. From my vantage point, climate change is not an environmental issue at all”Š”””Šit”™s an economic issue.

As ocean farmers, we reject aquaculture”™s obsession with monoculture, an obsession similar to that of modern land farming. Our goal is diversity. It”™s a sea-basket approach:We grow two types of seaweeds, four kinds of shellfish, and we harvest salt. But with over 10,000 edible plants in the ocean, we”™ve barely scratched the surface.

Instead of repeating history we”™re building infrastructure from seed-to-harvest-to-market. We”™re starting nonprofit hatcheries so that our farmers can access low-cost seed. We”™re creating ocean seed banks so that the Monsantos of the world can”™t privatize the source of our food and livelihoods.

Cleaning Up the Plastic Pollution in Our Oceans

This is an interesting talk on an important topic: cleaning up plastic in the ocean. ,a student from the Netherlands, looked to find a solution to a problem others said couldn’t be solved.

This is exactly the type of wonderful activity that inspired people can accomplish using science and engineering. He collected an understanding of the 50 issues that supposedly makes a solution impossible.

After getting funding (sparked by an explosion of viral social media) he worked on exploring the “insolvable” problems (having withdrawn from school to work on this problem). It is wonderful to see what we can do when inspired people use science and engineering to make the world a better place.

From their website, The Ocean Cleanup

In the feasibility report, we estimated that a 100-kilometer array operating in the North Pacific gyre for 10 years could remove 42% of the plastics in the area, or an estimated 70 million kilograms.

The plastic will be stored in an internal buffer within the platform at the tip of the V-shaped array. The plastic in the buffer will regularly be emptied onto a vessel that comes to collect it for transport to land. This will occur approximately once every six weeks, depending on the size of the vessel.

Besides monetary support, your relevant knowledge and skills may be a very welcome addition to The Ocean Cleanup. Our work requires not only scientific and technical expertise, but also assistance with legal, commercial and policy matters. If you would like to get actively involved in our work, If you would like to get actively involved in our work, please visit the careers page.

They aim to put a full scale pilot project in place in 3 to 4 years.
