Why Interstellar Travel Will Be Possible Sooner Than You Think

The term “moonshot” is sometimes invoked to denote a project so outrageously ambitious that it can only be described by comparing it to the Apollo 11 mission to land the first human on the Moon. The Breakthrough Starshot Initiative transcends the moonshot descriptor because its purpose goes far beyond the Moon. The aptly-named project seeks to travel to the nearest stars.

The brainchild of Russian-born tech entrepreneur billionaire Yuri Milner, Breakthrough Starshot was announced in April 2016 at a press conference joined by renowned physicists including Stephen Hawking and Freeman Dyson. While still early, the current vision is that thousands of wafer-sized chips attached to large, silver lightsails will be placed into Earth orbit and accelerated by the pressure of an intense Earth-based laser hitting the lightsail.

After just two minutes of being driven by the laser, the spacecraft will be traveling at one-fifth the speed of light—a thousand times faster than any macroscopic object has ever achieved.

Each craft will coast for 20 years and collect scientific data about interstellar space. Upon reaching the planets near the Alpha Centauri star system, an the onboard digital camera will take high-resolution pictures and send these back to Earth, providing the first glimpse of our closest planetary neighbors. In addition to scientific knowledge, we may learn whether these planets are suitable for human colonization.



While this endeavor may sound like science fiction, there are no known scientific obstacles to implementing it. This doesn’t mean it will happen tomorrow: for Starshot to be successful, a number of advances in technologiesare necessary. The organizers and advising scientists are relying upon the exponential rate of advancement to make Starshot happen within 20 years.

Here are 11 key Starshot technologies and how they are expected to advance exponentially over the next two decades.

1. Exoplanet Detection
An exoplanet is a planet outside our Solar System. While the first scientific detection of an exoplanet was only in 1988, as of 01 May 2017 there have been 3,608 confirmed detections of exoplanets in 2,702 planetary systems. While some resemble those in our Solar System, many have fascinating and bizarre features, such as rings 200 times wider than Saturn’s.

2. The reason for this deluge of discoveries? A vast improvement in telescope technology.
Just 100 years ago the world’s largest telescope was the Hooker Telescope at 2.54 meters. Today, the European Southern Observatory's Very Large Telescope consists of four large 8.2-meter diameter telescopes and is now the most productive ground-based facility in astronomy, with an average of over one peer-reviewed, published scientific paper per day.

3. Launch Cost
The Starshot mothership will be launched aboard a rocket and release a thousand starships. The cost of transporting a payload using one-time-only rockets is immense, but private launch providers such as SpaceX and Blue Origin have recently demonstrated success in reusable rockets which are expected to substantially reduce the price. SpaceX has already reduced costs to around $60 million per Falcon 9 launch, and as the private space industry expands and reusable rockets become more common, this price is expected to drop even further.

4. The Starchip
Each 15-millimeter-wide Starchip must contain a vast array of sophisticated electronic devices, such as a navigation system, camera, communication laser, radioisotope battery, camera multiplexer, and camera interface. The expectation we’ll be able to compress an entire spaceship onto a small wafer is due to exponentially decreasing sensor and chip sizes.

For Starshot to succeed, we will need the chip’s mass to be about 0.22 grams by 2030, but if the rate of improvement continues, projections suggest this is entirely possible.

5. The Lightsail
The sail must be made of a material which is highly reflective (to gain maximum momentum from the laser), minimally absorbing (so that it is not incinerated from the heat), and also very light weight (allowing quick acceleration). These three criteria are extremely constrictive and there is at present no satisfactory material.

6. Energy Storage

While the Starchip will use a tiny nuclear-powered radioisotope battery for its 24-year-plus journey, we will still need conventional chemical batteries for the lasers. The lasers will need to employ tremendous energy in a short span of time, meaning that the power must be stored in nearby batteries.

7. Lasers
Thousands of high-powered lasers will be used to push the lightsail to extraordinary speeds.

8. Speed
Achieving 20% speed of light for Starshot would represent a 1000x speed increase for any human-built object.

9. Memory Storage

Fundamental to computing is the ability to store information. Starshot depends on the continued decreasing cost and size of digital memory to include sufficient storage for its programs and the images taken of Alpha Centauri star system and its planets.

10. Telecommunication
Once the images are taken the Starchip will send the images back to Earth for processing.

The bandwidth and speed required for Starshot to send digital images over 4 light years—or 20 trillion miles—will require taking advantage in the latest telecommunications technology.One promising technology is Li-Fi, a wireless approach which is 100 times faster than WIFI. 

11. Computation

The final step in the Starshot project is to analyze the data returning from the spacecraft. To do so we must take advantage of the exponential increase in computing power, benefiting from the  trillion-fold increase in computing over the 60 years.

Lockheed Martin Airships are the next generation in transport

About four years ago +Julie Magnone and I were meeting with one of our energy logistics clients. We had been engaged for our oversize logistics expertise to collaborate with their engineers in designing modules of their gas production plant. The goal being to optimise the design for operational efficiency, cost effective construction and transport.
From a pure construction and operational integrity standpoint the engineers were wanting to build modules as large as possible. So large that it made the land transport task impossible. We could easily transport the module sizes they wanted from overseas to the Port of Brisbane but getting them to site in central Queensland at that size was impossible due to numerous overhead bridges, power lines, railway lines, narrow roads etc en-route.
I remember clearly one of the engineers refusing to accept it was impossible and seriously demanding that we find airships that could move the cargo to site from the Port of Brisbane. Julie and I left the meeting thinking that he was slightly mad but nonetheless we did some research anyway and at that time there wasn't any airship flying capable of lifting more than a few tonnes at the most.
Well...not anymore thanks to Lockheed Martin.

A prototype, like the one pictured, is operational. It has a 7X improved cargo payload compared to what we found in earlier generation airships of 21000kg. The cargo bay is 18m long x 3m wide x 3m high and able to accommodate standard shipping containers and various other types of loads.
These airships can travel at a speed of 60 knots or 111km/h and have a range of about 2500km. Due to a special air cushion landing system, much like a hovercraft concept, they can land on water as well.
For transport into remote areas these airships are far superior than helicopters in nearly every respect. They are quieter and more fuel efficient as well!

While the current prototype still could not solve the transport task our client set for us it is fair to say it probably won't be too long before cargo bays and payloads starting increasing making Airship cargo transport a commercial reality.
Depth Airships here we come!

NYK, MOL and K Line to merge container operations

Yesterday the three largest Japanese shipping lines Kawasaki Kisen Kaisha Ltd. (K-Line), Mitsui OSK Lines (MOL), and Nippon Yusen Kabushiki Kaisha (NYK) announced their agreement, subject to sign off by their respective boards and shareholder/regulatory approval, to establish a new joint-venture company and to integrate their container shipping operations.

M&A activity is sweeping the shipping industry globally as carriers in the wake of the Hanjin Shipping receivership fight to survive. The current wave of M&A activity is more about addressing structural industry issues by strengthening balance sheets, addressing poor investor returns and adapting to a low growth environment.

The industry still suffers from surplus capacity so M&A activity is needed to realign carriers and find synergies in cost reduction, economies of scale, improved competitive positioning and better protection from the prevailing weak industry fundamentals.

This announcement is another positive step for the industry where a significant number of carriers have not made money in the recent years. People that were affected by Hanjin's demise know the problems this caused and is still causing so hopefully another failure by a major carrier can be avoided.


The industry must navigate it's way back to a healthy and sustainable performance for all stakeholders as fast as it can.

New generation of car carrying ships now able to use the expanded Panama Canal

The term "Panamax" refers to ships of a size able to use the original Panama Canal. Prior to the expansion of the canal, which opened in July this year, some ships could not use the shortcut between North and South America. They were simply too big. Therefore many ships were designed and built to a maximum, "Panamax" size.

Since the opening of the expanded canal even the worlds largest ships can travel via the canal thus saving time and money. Ship owners have been building new bigger ships to take advantage of the improved economies of scale. These are called "Post-Panamax" ships.

Hoegh Autoliners now operates the worlds largest PCTC(Pure Car & Truck Carrier) and Post-Panamax ship in the "Hoegh Target". In fact she is the first PCTC of this size to transit via the canal.

The "Hoegh Target" can carry an incredible 8500 cars and has 71400 square metres of deck space. Importantly she is very fuel efficient and Hoegh claim will halve the emissions per car that they carry.

Here are a some pictures of her in the expanded Panama Canal.



Innovative vessels like this and the expanded Panama Canal are contributing to keeping freight rates lower for shippers.
