Recent revelations of NASA’s Eagleworks Em Drive caused a sensation on the internet as to why interstellar propulsion can or cannot be possible. The nay sayers pointed to shoddy engineering and impossible physics, and ayes pointed to the physics of the Alcubierre-type warp drives based on General Relativity.

So what is it? Are warp drives feasible? The answer is both yes and no. Allow me to explain.

The empirical evidence of the Michelson-Morley experiment of 1887, now known as the Lorentz-FitzGerald Transformations (LFT), proposed by FitzGerald in 1889, and Lorentz in 1892, show beyond a shadow of doubt that nothing can have a motion with a velocity greater than the velocity of light. In 1905 Einstein derived LFT from first principles as the basis for the Special Theory of Relativity (STR).

So if nothing can travel faster than light why does the Alcubierre-type warp drive matter? The late Prof. Morris Klein explained in his book, Mathematics: The Loss of Certainty, that mathematics has become so powerful that it can now be used to prove anything, and therefore, the loss of certainty in the value of these mathematical models. The antidote for this is to stay close to the empirical evidence.

Companies looking to launch satellites into space typically spend anywhere from $10–50 million per launch but thanks to 3D printing, those costs are set to drop in a big way.

For $4.9 million, businesses can use RocketLab to send small satellites into orbit. The firm’s engine, called the Rutherford, is powered by an electric motor and is the first oxygen and hydrocarbon engine to use 3D printing for all its primary components. The New Zealand company is set to begin test flights this year and aims to launch weekly commercial operations next year. Read more

A better way to deliver innovation to the world

Cryptocurrency aficionados have been discussing Bitcoin limitations ever since the blockchain buzz hit the street. Geeks toss around ideas for clearing transactions faster, resisting potential attacks, rewarding miners after the last coin is mined, and supporting anonymity (or the opposite—if you lean toward the dark side). There are many areas in which Bitcoin could be improved, or made more conducive to one camp or another.

Distinguished Penn State professor, John Carroll, believes that Bitcoin may eventually be marginalized due to its early arrival. He believes that its limitations will eventually be overcome by newer “altcoins”, presumably with improved mechanisms.

So, does progress in any of these areas threaten the reigning champ? It’s unlikely…

More than any other individual, Andreas Antonopoulos is the face of Bitcoin. We discussed this very issue in the outer lobby of the MIT Bitcoin Expo at which he was keynote speaker (March 2015). Then, we discussed it again, when I hosted his presentation at The Bitcoin Event in New York (also in March). He clearly and succinctly explained to me why it is unlikely that an altcoin will replace Bitcoin as the dominant—and eventually surviving—cryptocurrency…

Game-changing technologies can be a waste of money or a competitive advantage. It depends on the technology and the organization.

It seems like the term “game-changing” gets tossed around a lot lately. This is particularly true with respect to new technologies. But what does the term mean, what are the implications, and how can you measure it?

With regarding to what it means, I like the MacMillan dictionary definition for game-changing. It is defined as “Completely changing the way that something is done, thought about, or made.” The reason I like this definition is it captures the transformational nature of what springs to mind when I hear the term game-changing. This should be just what it says. Not just a whole new ball game, but a whole new type of game entirely.

Every industry is unique. What is a game-changer for one, might only be a minor disruption or improvement for another. For example, the internal combustion engine was a game-changer for the transportation industry. It was important, though less of a game-changer for the asphalt industry due to secondary effect of increased demand for paved roads.

I read all the news about SpaceX’s Falcon 9 latest “failure” to land on an autonomous spaceport drone ship aka barge. I view these as trials to success. Here’s why.

1. Grasshopper Successes: The two videos below show that the early landing trials aka Grasshopper from several heights between 250m and 1,000m.

The lessons here are:

a) Pinpoint landing of a 1st stage rocket is technologically feasible.

“The inherently robotic system begs to be humanized and explained. The first question Taylor had to ask himself was if what Tocchini was attempting was even possible. Could he translate design intention into an algorithm that was always producing new and relevant results—something that satisfied a broad range of needs and desires?” Read more

Alex Davies — WiredAn autonomous car just drove across the country.

Nine days after leaving San Francisco, a blue car packed with tech from a company you’ve probably never heard of rolled into New York City after crossing 15 states and 3,400 miles to make history. The car did 99 percent of the driving on its own, yielding to the carbon-based life form behind the wheel only when it was time to leave the highway and hit city streets.

This amazing feat, by the automotive supplier Delphi, underscores the great leaps this technology has taken in recent years, and just how close it is to becoming a part of our lives. Yes, many regulatory and legislative questions must be answered, and it remains to be seen whether consumers are ready to cede control of their cars, but the hardware is, without doubt, up to the task.

One of the things that I’ve always liked about Star Trek, is the concept of a galaxy spanning civilization. I would expect that before we ever get to that point, we will have a civilization that spans our solar system. Having a solar system spanning civilization has many advantages. It would give us access to resources many times greater than what is found here on Earth. It also provides the opportunity for civilization to expand, and in a worst case scenario, help ensure the survival of humanity.

Millions of people living in spacious environmentally controlled cities on planetary surfaces and in rotating cylinders in free space, with industry that extends from Mercury to the comets is to me, a grand vision worthy of an ambitious civilization. But trying to make that vision a reality will be difficult. The International Space Station has the capacity to house just six people and cost approximately $100B to put in place. With a little simple division, that works out to about $17B per inhabitant! If we used that admittedly crude figure, it would cost $17 trillion to build a 1,000 person habitat in Earth orbit. Clearly, the approach we used to build the ISS will not work for building a solar system civilization!

The ISS model relies on building everything on Earth, and launching it into space. A different model championed by Dr. Philip Metzger, would develop industrial capacity in space, using resources close to home, such as from the Moon. This has the potential to greatly reduce the cost of building and maintaining systems in space. But how to develop that industrial capacity? Remember we can’t afford to launch and house thousands of workers from Earth. The answer it would seem, is with advanced robotics and advanced manufacturing.

But is even this possible? The good news is that advanced robotics and advanced manufacturing are already being rapidly developed here on Earth. The driver for this development is economics, not space. These new tools will still have to be modified to work in the harsh environment of space, and with resources that are different from what are commonly used here on Earth. While learning to adapt those technologies to the Moon and elsewhere in the solar system is not trivial, it is certainly better that having to develop them from scratch!
