Scalable, fast, easy and cheap solutions when we get serious about avoiding climate doomsday

New York Magazine David Wallace-Wells decided to go full doomer with “When the Earth will become uninhabitable”. They got their most read article ever, so they will probably keep it up. The combination of dooms proposed * maximum climate warming per models which have overestimated warming to this point * adding in maximum feedback effects …

Combining geoengineering approaches would keep constant temperatures and overall rainfall

New research from an international team of atmospheric scientists published by Geophysical Research Letters investigates for the first time the possibility of using a “cocktail” of geoengineering tools to reduce changes in both temperature and precipitation caused by atmospheric greenhouse gases. Carbon dioxide emissions from the burning of coal, oil, and gas not only cause …

Tests for safe Geoengineering should start now

Technology Review summarizes some of the arguments for and against geoengineering. Alan Robock, a professor of environmental sciences at Rutgers, has published a list of 27 risks and concerns raised by the technology, including its potential to deplete the ozone layer and to decrease rainfall in Africa and Asia. Ultimately, Robock worries that geoengineering may …

World will blow through Two Degree CO2 and have to look at Geoengineering even if all electricity went solar and all cars are electric

On the low estimate for 1.5C degree change, the world is about 14 months away from using up the permitted CO2 emissions. On the low estimate for 2C degree change, the world is less than ten years away from using up the permitted CO2 emissions. China added 5% more power generation in 2016. This was …

“Glassy carbon” electrodes transmit more robust signals to restore motion in people with damaged spinal cords

When people suffer spinal cord injuries and lose mobility in their limbs, it’s a neural signal processing problem. The brain can still send clear electrical impulses and the limbs can still receive them, but the signal gets lost in the damaged spinal cord. The Center for Sensorimotor Neural Engineering (CSNE)–a collaboration of San Diego State …

Climate scientists know we cannot prevent 2 degree global change without geoengineering

In 2008 some climate scientiss said that the world had 100 months to enact drastic anti-global warming policies to avoid the environment warming by two degrees celsius compared to pre-industrial times. The 100 months have passed and only modest policies have been enacted and it seems likely that some of the policies will be reverse …

Customized on demand 3D printed drones produced in less than 24 hours from spec to completion

US Army Research lab has created on demand custom 3d printing of drones. With this concept, once a patrol requires UAV support, Soldiers input all their requirements into mission planning software. The system then knows the optimal configuration for the aerial vehicle and it’s printed and delivered within 24-hours. This isn’t just about UASs,” Spero …

Scale of the threat to US supercarriers from China’s submarines

The Chinese Navy consists of approximately 26 destroyers (21 of which are considered modern), 52 frigates (35 modern), 20 new corvettes, 85 modern missile armed patrol craft, 56 amphibious ships, 42 mine warfare ships (30 modern), more than 50 major auxiliary ships, and more than 400 minor auxiliary ships and service/support craft. During 2013, more …

Stratospheric Sulfate Geoengineering would be effective and affordable to mitigate climate change

Stratospheric sulfate aerosol geoengineering may mitigate effects of climate change. Sulfate could be mixed into jet fuel so that contrails would spread the sulfate into the stratosphere. We would mimick a volcano. If we put 5 billion tons of sulfates a year into the atmosphere 20 kilometers high, and do that for 50 years. These …

Advanced memristors are a pathway to affordable human scale neuromorphic artificial general intelligence

It may be possible to create neuromorphic human-level Artificial General Intelligence within 5 to 15 years for 30 to 100 thousand dollars, of marginal cost using memristors. The extreme complexity of the human cerebral cortex,featuring in particular ~10^14 synapses, makes the hardware implementation of neuromorphic networks with a comparable number of devices exceptionally challenging. One …

US hit another post-1973 oil production record and oil storage space is shrinking worldwide

US crude oil production hit another post-1973 record with 9.213 million barrels per day. Oil storage space is shrinking in the US and Europe as USA and Saudi Arabia and OPEC are not cutting back on production. Oil tankers are once again being heavily used to store crude oil by oil traders who are counting …
