Boeing’s new laser canon can destroy drones in mid-flight
Drones are everywhere these days. They’re at your local park, they’re in the ocean, they’re hovering over the White House lawn, and they may even be hovering overhead armed with tear gas.
In a world that’s becoming increasingly drone friendly, there are some serious safety considerations that shouldn’t be ignored.
Specifically, government and military officials have cautioned that drones might soon be outfitted with explosives or chemical weapons and flown into either public or sensitive spaces.
With that in mind, Boeing recently developed a portable laser cannon that can eviscerate unwanted and pesky drones mid-flight. In the future, these types of lasers might be installed in all sorts of locations, including airports and sensitive military installations.
Terminator-style ‘skin’ quickly repairs itself after a gunshot | New Scientist
Other self-healing plastics exist, but they take much longer to repair themselves. The ability to instantly plug holes could be especially useful to protect structures in space, where flying objects can puncture spacecraft or orbiting habitats. The plastic could be incorporated into their walls, creating a seal if the atmosphere inside a vessel starts to leak out, putting astronauts at risk.
Other fabrics take a different approach: stopping projectiles altogether. A futuristic tissue combining human skin cells with spider silk can cushion a gunshot when fired at half speed. Pure graphene, which is made up of layers of carbon one-atom thick, is being investigated for use in bulletproof armour because it can handle blows better than steel.

Glass paint could keep metal roofs and other structures cool even on sunny days
Sunlight can be brutal. It wears down even the strongest structures, including rooftops and naval ships, and it heats up metal slides and bleachers until they’re too hot to use. To fend off damage and heat from the sun’s harsh rays, scientists have developed a new, environmentally friendly paint out of glass that bounces sunlight off metal surfaces—keeping them cool and durable.
The researchers present their work today at the 250th National Meeting & Exposition of the American Chemical Society (ACS).
“Most paints you use on your car or house are based on polymers, which degrade in the ultraviolet light rays of the sun,” says Jason J. Benkoski, Ph.D. “So over time you’ll have chalking and yellowing. Polymers also tend to give off volatile organic compounds, which can harm the environment. That’s why I wanted to move away from traditional polymer coatings to inorganic glass ones.”

Cities are often seen as the flipside of nature: synthetic, sleek and sometimes impersonal. For places that pine after being greener, the Solitair tree nursery provides a blueprint.
What If We Had Another Earth?
A realistic and desirable human destination would produce a different space program than what we have today.
“We reach for new heights and reveal the unknown for the benefit of humankind.” This is NASA’s Vision Statement. This is NASA’s reason for being, its purpose. This is a vision statement for science and knowledge. This vision statement was crafted in a solar system that has only one planet that is environmentally friendly to human life.
Thanks to the ongoing search for exoplanets, we’ve identified several planets in our galaxy that are Earth sized and in their star’s habitable zone. Based on statistics, potentially billions more are waiting to be found. We are just now developing the technology to detect them. But we’re nowhere near having the technology needed to get to visit them. They are simply too far away.
Now here is where I’d like to pose a what if question: What if there was another habitable planet just like Earth, right here in our own solar system? What would Earth’s space programs look like, if anyone with a good telescope could look up and see another world with oceans, and continents, and clouds, and green forests? I think that it is safe to say that space programs in this imaginary solar system would be vastly different than ours today. This is conjecture, but it seems likely that the vision statement above, would be more in line with making that new world available for humanity.
Of course the key difference between our present reality and this imaginary scenario is the existence of an obviously desirable destination relatively close by to Earth. This lack of obviously desirable destinations has shaped space programs into the form we see them today. The science oriented form described in the current NASA vision statement is a good example.
It has been said that leadership begins with a vision. To be compelling, a vision describes a desirable end state to be obtained. In the case of the fictional scenario with another Earth like planet in the solar system, that leadership vision might include making it possible for people to move freely to this new world.
As an analogy, in the mid 1800’s, the transcontinental vision (paraphrased) was to secure the U.S. position on the Pacific through a speedy and direct means of travel from one coast to the other. That vision did not include establishing and building the city of San Francisco! The prior existence of San Francisco, enabled the vision of a transcontinental railroad.
Since our situation lacks a visible desirable destination, a bit more effort is required in the vision department. We know that the solar system contains all the resources we need in order to construct vast places for people to live. Immense structures with forests, streams and farmland as advocated by Dr. Gerard O’Neill back in the 1970’s are all possible. We can achieve the same vision of having another habitable planet in this solar system, we just have to add the intermediate step of a vision to develop the manufacturing capability to construct our own desirable destinations!
Using the transcontinental vision as a guide, it is premature for the space vision to focus on sending millions of people out into space, since apart from the International Space Station, there are no destinations yet! No, to get to the transcontinental vision for space, we first need a vision of building a San Francisco in space! But in order for that vision to be considered, it must be realistic. The focus would be on developing the tools and robots necessary to rapidly and economically build up in-space manufacturing industries that can begin the construction of the first villages that will grow into the human cities.
Even though we do not have another Earth in our solar system, it is possible to envision the creation of other Earth equivalents. This leap in leadership would produce a vision unlike what we have now. This new vision, focused on manufacturing and development utilizing the resources of our solar system, would empower capabilities for even greater accomplishments in the future.
Book Review: The Human Race to the Future by Daniel Berleant (2013) (A Lifeboat Foundation publication)
From CLUBOF.INFO
The Human Race to the Future (2014 Edition) is the scientific Lifeboat Foundation think tank’s publication first made available in 2013, covering a number of dilemmas fundamental to the human future and of great interest to all readers. Daniel Berleant’s approach to popularizing science is more entertaining than a lot of other science writers, and this book contains many surprises and useful knowledge.
Some of the science covered in The Human Race to the Future, such as future ice ages and predictions of where natural evolution will take us next, is not immediately relevant in our lives and politics, but it is still presented to make fascinating reading. The rest of the science in the book is very linked to society’s immediate future, and deserves great consideration by commentators, activists and policymakers because it is only going to get more important as the world moves forward.
The book makes many warnings and calls for caution, but also makes an optimistic forecast about how society might look in the future. For example, It is “economically possible” to have a society where all the basics are free and all work is essentially optional (a way for people to turn their hobbies into a way of earning more possessions) (p. 6–7).
A transhumanist possibility of interest in The Human Race to the Future is the change in how people communicate, including closing the gap between thought and action to create instruments (maybe even mechanical bodies) that respond to thought alone. The world may be projected to move away from keyboards and touchscreens towards mind-reading interfaces (p. 13–18). This would be necessary for people suffering from physical disabilities, and for soldiers in the arms race to improve response times in lethal situations.
To critique the above point made in the book, it is likely that drone operators and power-armor wearers in future armies would be very keen to link their brains directly to their hardware, and the emerging mind-reading technology would make it possible. However, there is reason to doubt the possibility of effective teamwork while relying on such interfaces. Verbal or visual interfaces are actually more attuned to people as a social animal, letting us hear or see our colleagues’ thoughts and review their actions as they happen, which allows for better teamwork. A soldier, for example, may be happy with his own improved reaction times when controlling equipment directly with his brain, but his fellow soldiers and officers may only be irritated by the lack of an intermediate phase to see his intent and rescind his actions before he completes them. Some helicopter and vehicle accidents are averted only by one crewman seeing another’s error, and correcting him in time. If vehicles were controlled by mind-reading, these errors would increasingly start to become fatal.
Reading and research is also an area that could develop in a radical new direction unlike anything before in the history of communication. The Human Race to the Future speculates that beyond articles as they exist now (e.g. Wikipedia articles) there could be custom-generated articles specific to the user’s research goal or browsing. One’s own query could shape the layout and content of each article, as it is generated. This way, reams of irrelevant information will not need to be waded through to answer a very specific query (p. 19–24).
Greatly similar to the same view I have written works expressing, the book sees industrial civilization as being burdened above all by too much centralization, e.g. oil refineries. This endangers civilization, and threatens collapse if something should later go wrong (p. 32, 33). For example, an electromagnetic pulse (EMP) resulting from a solar storm could cause serious damage as a result of the centralization of electrical infrastructure. Digital sabotage could also threaten such infrastructure (p. 34, 35).
The solution to this problem is decentralization, as “where centralization creates vulnerability, decentralization alleviates it” (p. 37). Solar cells are one example of decentralized power production (p. 37–40), but there is also much promise in home fuel production using such things as ethanol and biogas (p. 40–42). Beyond fuel, there is also much benefit that could come from decentralized, highly localized food production, even “labor-free”, and “using robots” (p. 42–45). These possibilities deserve maximum attention for the sake of world welfare, considering the increasing UN concerns about getting adequate food and energy supplies to the growing global population. There should not need to be a food vs. fuel debate, as the only acceptable solution can be to engineer solutions to both problems. An additional option for increasing food production is artificial meat, which should aim to replace the reliance on livestock. Reliance on livestock has an “intrinsic wastefulness” that artificial meat does not have, so it makes sense for artificial meat to become the cheapest option in the long run (p. 62–65). Perhaps stranger and more profound is the option of genetically enhancing humans to make better use of food and other resources (p. 271–274).
On a related topic, sequencing our own genome may be able to have “major impacts, from medicine to self-knowledge” (p. 46–51). However, the book does not contain mention of synthetic biology and the potential impacts of J. Craig Venter’s work, as explained in such works as Life at the Speed of Light. This could certainly be something worth adding to the story, if future editions of the book aim to include some additional detail.
At least related to synthetic biology is the book’s discussion of genetic engineering of plants to produce healthier or more abundant food. Alternatively, plants could be genetically programmed to extract metal compounds from the soil (p. 213–215). However, we must be aware that this could similarly lead to threats, such as “superweeds that overrun the world” similar to the flora in John Wyndam’s Day of the Triffids (p. 197–219). Synthetic biology products could also accidentally expose civilization to microorganisms with unknown consequences, perhaps even as dangerous as alien contagions depicted in fiction. On the other hand, they could lead to potentially unlimited resources, with strange vats of bacteria capable of manufacturing oil from simple chemical feedstocks. Indeed, “genetic engineering could be used to create organic prairies that are useful to humans” (p. 265), literally redesigning and upgrading our own environment to give us more resources.
The book advocates that politics should focus on long-term thinking, e.g. to deal with global warming, and should involve “synergistic cooperation” rather than “narrow national self-interest” (p. 66–75). This is a very important point, and may coincide with the complex prediction that nation states in their present form are flawed and too slow-moving. Nation-states may be increasingly incapable of meeting the challenges of an interconnected world in which national narratives produce less and less legitimate security thinking and transnational identities become more important.
Close to issues of security, The Human Race to the Future considers nuclear proliferation, and sees that the reasons for nuclear proliferation need to be investigated in more depth for the sake of simply by reducing incentives. To avoid further research, due to thinking that it has already been sufficiently completed, is “downright dangerous” (p. 89–94). Such a call is certainly necessary at a time when there is still hostility against developing countries with nuclear programs, and this hostility is simply inflammatory and making the world more dangerous. To a large extent, nuclear proliferation is inevitable in a world where countries are permitted to bomb one another because of little more than suspicions and fears.
Another area covered in this book that is worth celebrating is the AI singularity, which is described here as meaning the point at which a computer is sophisticated enough to design a more powerful computer than itself. While it could mean unlimited engineering and innovation without the need for human imagination, there are also great risks. For example, a “corporbot” or “robosoldier,” determined to promote the interests of an organization or defeat enemies, respectively. These, as repeatedly warned through science fiction, could become runaway entities that no longer listen to human orders (p. 83–88, 122–127).
A more distant possibility explored in Berleant’s book is the colonization of other planets in the solar system (p. 97–121, 169–174). There is the well-taken point that technological pioneers should already be trying to settle remote and inhospitable locations on Earth, to perfect the technology and society of self-sustaining settlements (Antarctica?) (p.106). Disaster scenarios considered in the book that may necessitate us moving off-world in the long term include a hydrogen sulfide poisoning apocalypse (p. 142–146) and a giant asteroid impact (p. 231–236)
The Human Race to the Future is a realistic and practical guide to the dilemmas fundamental to the human future. Of particular interest to general readers, policymakers and activists should be the issues that concern the near future, such as genetic engineering aimed at conservation of resources and the achievement of abundance.
