Fusion deficient


Humans' ability to harness energy, propelled tactically by the Sun, remain meager. Unfortunately, they have not even been able to replicate the processes in the Sun that apparently throws of seemingly unlimited free energy. Fusion, hot and cold, eluded the struggling species, with nearly 30% still without proper food, clothing and shelter. Lifting humanity from despair remains to be an energy problem, something not many are focused on.

The simplest of processes, fusing two Hydrogen atoms into one of Helium and releasing an abundance of energy, still remains outside the grasp of the engineers. Recent news from the famous defense contractor was encouraging but the path to practical implementation still seems too long. And the crooks who raised false hope on cold fusion seem to have gone away. Tactical conversion of Sun's power - solar and wind - still seem too expensive and rather cumbersome. And, if the energy secretary ever goes to school and perhaps learn something, he may learn that fossil fuel is not the answer either.

The answer appears to be tantalizingly close in fusion. The template is readily available and a generation of great technologists stand ready to convert dreams into practical applications. What is missing is imagination, something that cannot be taught or bought. Perhaps, we need a bit of luck.

The code

Humans and their cousins, the apes, have been exceptional in facial recognition. Their life depended on it for the ability to recognize a friend from a foe was crucial for survival. Recent research from Caltech (1) appears to get closer to the neural code for face recognition. The trick appears to be specialization with singular neurons, focused on specific features. The idea appears to validate recent advances in deep learning for image recognition and it could provide further impetus to the acceleration of artificial intelligence.
The idea that single neurons encode specific features has been tantalizing for deep learning enthusiasts. It allows scalability in deep neural networks with increasing specialization in layers. The single feature specificity at the neuron level and its ability to make binary decisions provide further evidence of micro compartmentalization and voting based decision-making. Complementarity, communication and cooperation appear to dominate in goal seeking and that has implications for future research in computerized image recognition and more broadly, artificial intelligence.
The neural code developed by primates, an efficient and massively parallel processed algorithm that helped them survive and evolve, could be replicatable. Hopefully, those who get hold of this will use it wisely.

The DART

The space administration's plans to throw a refrigerator at an incoming small asteroid (1) to demonstrate fancifully worded, "kinetic impactor technique," is ample proof that humans are sitting ducks on the blue planet surrounded by big and fast objects. Momentum has been known for a while and if one can impact the direction of the approaching object slightly, it could be beneficial. But to be effective, such a maneuver has to be very early in the trajectory of the approaching object. Combined with a lack of knowledge of projectiles moving toward us, it remains to be a probability game - and the odds are likely against the species, still trying to kill each other around the world.


If the state of the art is studying the effect of an impact of a heavy projectile on an approaching asteroid, it seems that we have not advanced sufficiently to survive. If the best minds in practical space exploration are engaged in tactics, we may be in more terrible shape than could be imagined. Aided by policy making ignoramuses in the capitol, trying to cut funding for fundamental research, we now have a stagnant knowledge regime, unable to advance science and humanity. To make matters worse, we have engineers and technologists focused on applying old ideas just to win funding. 


Stupidity has a price. In most past failed experiments in civilizations, it ended up with an ignorant leader perpetuating tactics surrounded by those currying for favor by applying old ideas to solve new problems.
