I want to build a 21st century farm. I’ll start with a solar array and a wind generator (probably a chimney). I’ll store energy in a liquid storage facility using a redox flow battery. Then using the storage cell I’ll run a CO2 extractor and maybe a water purifier.
Then I’ll build a sealed building similar to the PlantLab system. I’ll use red and blue LED’s on for 20 hours per day (or whatever is the optimum day/night cycle for the specific food I’m growing), high concentrations of CO2, and optimum temperature/humidity to grow food dramatically faster than a traditional farm.
There are very few consumables needed, some fertilizer and seeds. It’s not clear to me how long a wind generator or solar array can last. I’m sure eventually something will be needed for repair or maintenence.
Depending on the outdoor temperature this system could work for decades. If the greenhouse were buried in 57F degree ground and well insulated it may not lose much heat to the ground.

I really like Quanta Magazine. I wish I had time to read all the interesting articles they publish, like this one about DWave and quantum computing.

Here is a interesting article from phys.org about modifying superconductivity using stress. Film stress in the semiconductor industry can change electrical properties of conductors so this makes perfect sense.
At an atomic level the concept of stress is simply the distance between atoms or molecules. In an equilibrium state the atoms want to be a specific distance from each other. Due to the formation process the atoms may be a little too close or too far from each other. Technically this is not an equilibrium state, but the positions can be locked in place so that it is difficult for the film to relax. Moderate levels of compressive and tensile stress can be stable in the long term.
It would be interesting to deposit some high temperature superconductors at a variety of film stresses ranging from compressive to neutral to tensile and see how the critical temperature and critical magnetic field depend on the stress.
On a side note, I met Lee, Richardson, and Osheroff at the 1996 Nobel Prize ceremonies. They were all friendly and exciting people to be around.

In the future robots will watch robots killing robots. Today humans are the spectators for Battlebots. It's a visual feast of carnage, explosions, fire, and wreckage.
Robot wars are coming, soon robots will be capable of killing humans and attacking robots at the same time.

Artificial intelligence routines are now being used to develop new materials. It sounds like the work is highly derivative, searching for minor changes in a set of similar materials. But it's work that could not have been done by machines 20 years ago.

Transcranial stimulation is growing and appears headed for explosive growth. There are 3 new devices on the market.
Thync looks like something out of a science fiction movie.
Foc.us and Halo are intriguing.
Reddit even has a section on tDCS.
Last year I would have bet that AI teachers were still a decade away. Turns out they are actively working with students. Here's an article in the Washington Post about a virtual teaching assistant at Georgia Tech.
Here's an interesting New Yorker article on VR Movies.
I wish I could invest in this, VR will dominate movies in a decade.
Perhaps not, at least when we are rushed into a decision.
But what I find really odd is that the people who think we have no free will are insistent that we convert to their position, whether it's their religious opinion, or their political preferences.
My friend Harry Kroto was a committed atheist who believed I had no free will, that I had no choice whether or not to be a Christian. And yet he would not give up trying to commit me to atheism.
I asked Viv to find us a presidential candidate we could all be proud to support. It's response was "I'm ready to serve."
I shall miss you with all my heart. You smiled when you were happy, you smiled when you were angry, you smiled when you were tired, you smiled when you were everywhere.
You were there with me when Challenger exploded, when I was frustrated and lonely, when I could not care less about carbon, when I was successful and enthusiastic about buckyballs. You told me my career had peaked when I was 23 years old. I think you were right.
Harry Kroto was one of the greatest scientists in history because he understood joy and connected it to science better than anyone I have ever met. He laughed and smiled at all things science.
It is with the utmost respect that I must sadly report that Harry has gone to meet his maker (or maybe not), he is pushing up daisies, he has joined the choir invisible. Sir Harold Walter Kroto, FRS is an ex-chemist.
Goodbye my friend
Here is Stuart Hameroff's website. He has some interesting theories.
And here is an article by Sir Roger Penrose and Dr. Hameroff about Quantum Consciousness and here are some of their other articles.
I enjoyed this article by Stuart Hameroff challenging Richard Dawkins. I'm glad to see there are other professionals out there who do not blindly accept Dr. Dawkins' theories.
Here's an article on the Evolutionary Argument Against Reality.
