learning morse code the army way

on developing style

Related to the project a friend worked on at MIT in the 70s. Marvin Minsky's group received a lot of funding from the military. In this case to write software that would identify separate threads of morse code that happened to be broadcast on the same frequency.   The approach was to identify styles.   The friend ended up writing computer games instead (Zork) and founding an early game company (Infocom)

a very clever stable carbon sequestration technique

And it isn't outrageously expensive. Of course much would have to change before any of this happens and few in power treat this as the emergency it is.

Scalable, economical, and stable sequestration of agricultural fixed carbon

Eli Yablonovitch and Harry W. Deckman

Significance

This article presents a carbon-negative solution to the world’s CO2 emissions by stably sequestering carbon that has been photosynthetically fixed by cultivated plants. The technology buries salted biomass in a dry environment within an engineered biolandfill. The key to stable sequestration is the recognition that a dry environment assisted by salt preserves biomass. Preservation by salt has actually been known since Biblical times. Salt effectively reduces the relative humidity of the sequestered biomass, preventing decomposition for thousands of years. Current agricultural and biolandfill costs indicate US$60/tonne of sequestered CO2, corresponding to ~US$0.53 per gallon of gasoline. A significant fraction of world emissions can be sequestered.

Abstract

We describe a scalable, economical solution to the carbon dioxide problem. CO2 is captured from the atmosphere by plants, and the harvested vegetation is then buried in an engineered dry biolandfill. Plant biomass can be preserved for hundreds to thousands of years by burial in a dry environment with sufficiently low thermodynamic “Water Activity,” which is the relative humidity in equilibrium with the biomass. Maintaining a dry environment within the engineered dry biolandfill is assisted by salt that preserves biomass, which has been known since Biblical times. A “Water Activity” <60%, assisted by salt, will not support life, suppressing anaerobic organisms, thus preserving the biomass for thousands of years. Current agricultural costs, and biolandfill costs, indicate US$60/tonne of sequestered CO2 which corresponds to ~US$0.53 per gallon of gasoline. The technology is scalable owing to the large area of land available for nonfood biomass sources. If biomass production is scaled to the level of a major crop, existing CO2 can be extracted from the atmosphere, and will simultaneously sequester a significant fraction of world CO2 emissions.

Fueled by the rise of social media and a lucrative, unregulated supplements industry, more boys and young men today are bulking up to the point of risking their overall health. A measured amount of weight training can be positive and healthy, but it’s neither when body image turns into an obsession or exercise becomes excessive.

But when Gattacceca obtained a piece of Black Beauty and tried to decode its magnetic inscription, he found its memory had been wiped—Men in Black style—and replaced by a stronger signal. He instantly knew the culprit. Somewhere along its journey from Moroccan desert to street dealers to laboratory, the rock had been touched by strong hand magnets, a widely used technique for identifying meteorites. “It’s a pity that, just by using magnets, we’ve been destroying this scientific information that was stored there for 4 billion years,” Gattacceca says.

Abstract

Energy-efficient, healthy lighting is vital for human beings. Incandescent lighting provides high-fidelity color rendering and ergonomic visual comfort yet is phased out owing to low luminous efficacy (15 lumens per watt) and poor lifetime (2000 hours). Here, we propose and experimentally realize a photon-recycling incandescent lighting device (PRILD) with a luminous efficacy of 173.6 lumens per watt (efficiency of 25.4%) at a power density of 277 watts per square centimeter, a color rendering index (CRI) of 96, and a LT70-rated lifetime of >60,000 hours. The PRILD uses a machine learning–designed 637-nm-thick visible-transparent infrared-reflective filter and a Janus carbon nanotube/hexagonal boron nitride filament to recycle 92% of the infrared radiation. The PRILD has higher luminous efficacy, CRI, and lifetime compared with solid-state lighting and thus is promising for high–power density lighting.

Legislation has advanced more than in other states.  It mostly ignores the technical impossibility of a working state-wide ban. Also, while the worries about China may be real, American sites like Instagram, Facebook, Amazon collect even more personal information, often selling 'you' to other companies and even governments without you knowledge.    I'm no fan of these companies, but we should be honest.
