January 27, 2018 – My wife and I have been going to Costa Rica for the last two years and are about to return to that country next week. For lots of reason Costa Rica is a terrific place to visit, and may even be a place where we inevitably choose to spend much of our time in the future. The country ranks first on the Happy Planet Index (HPI) not because it is a wealthy nation, but because in measuring its population wellbeing, life expectancy, income inequality, and ecological footprint, Costa Rica comes out on top.

HPI, in future, may prove more important than GDP, the current way we measure national success. Purely economic, GDP tells governments very little about the wellbeing of citizens, how stressful their lives are, how it impacts jobs and family, and how ultimately measures whether people are happy or not. But in the age of anthropogenic climate change with extreme weather events, HPI may ultimately provide nations with a means to measure future success.

Until this generation, most of us felt our children would enjoy a better life than the one we have had. Not anymore. The most recent surveys in North America and Europe state the opposite. Our measure of success, GDP, is letting us down because it isn’t designed to measure inequality in wealth distribution, social disruption from extreme weather, geopolitical uncertainty from nuclear proliferation, cyberterrorism, and more. GDP is incompatible with our planetary limits because it is growth-oriented exclusively.

Getting back to why Costa Rica is number one when its GDP per capita is one-quarter that of richer nations in Europe and North America, has everything to do with balance. The country’s economy is built on tourism and agricultural exports. It has no army, abolished in 1949. It spends government raised funds on education, health, pensions, and preserving the environment. It invests more per capita in education and health than the United Kingdom. It protects its forests and generates 99% of its electricity from renewable sources. Costa Rica is likely to be the first country on the planet to become carbon neutral.

By no means are all Costa Ricans happy. There is still income inequality, and the environmental effort towards sustainability has a few warts. But Costa Ricans say hello and goodbye with the words “pura vida,” which translates to English as “pure life” or “good life.” 

Costa Rica fascinates me for more than just its HPI. Although the country is wed to tourism and agriculture, it also is experimenting with a number of technological innovations that place it at the forefront of the 21st century.

Powering a Country without Carbon

A car trip across Costa Rica takes you to the central spine of the country where wind turbines sprout everywhere. Costa Rica has been harvesting wind now for several decades. It also has constructed a major hydroelectric facility in the north creating an artificial lake, the largest in the country, that serves as a source of irrigation water for much of the farmland in Guanacaste, the driest state in the country. Added to hydro and wind is geothermal energy. That same spiny ridge where wind turbines are in abundance features a series of volcanoes with geothermal energy potential.

Last year when we visited Rincon, one of Costa Rica’s many volcanoes, we saw evidence of the country’s investment in geothermal energy which is greater than countries like Iceland, and New Zealand, both known for this type of energy source. The challenge for the country is to ensure that its commitment to preserve its natural habitats does not get compromised by the build-out of geothermal plants, some of which are causing incursions into the country’s conservation zones. By 2025 Costa Rica plans to grow the number of geothermal plants to nine in total from the current six. This will make this West Virginia-sized country one of the top ten in the world in geothermal technology and capacity.

Geothermal, wind, hydroelectricity, and the beginning of an investment in solar may make the country the first negative emissions state.

Smart Agriculture and Biochar to Reduce Greenhouse Gases, Fertilizer and Pesticide Use

Which country or state is the largest producer of pineapples in the world? It’s not Hawaii. It’s Costa Rica. Pineapple is a pretty intensive crop to grow. Fertilizers, pesticides and machine use make producing these fruit carbon intensive. At the University of Costa Rica’s Environmental Pollution Research Centre (CICA), however, agricultural scientists are working with biochar from pineapple residue. Waste from pineapple harvesting amounts to 10 million tons every 18 months. The pineapple after-harvest residue is a source of greenhouse gas emissions and a breeding ground for insect pests that devastate local cattle.

Turning the pineapple residue into biochar seems like a good idea. It can replace fertilizer and sequester carbon at the same time. The scientists are studying the impact of introducing biochar into fields growing pineapple by using trace radioactive Carbon 14 (14C), the same carbon used to date archeological finds.  The 14C will help establish the resiliency of carbon sequestration done this way.

Biochar application from pineapple residue can be used on pasture as well helping to offset greenhouse gas emissions from dairy and beef cattle. Researchers are directly gathering soil emissions data from farmers’ and ranchers’ fields. States Mohammad Zaman, a soil scientist, “This information arms policymakers with sufficient knowledge to make informed decisions about national and international carbon policies, which will ultimately determine the future of the planet.”

Costa Rican researchers are studying using biochar in agriculture to sequester carbon.

 

Contributing to Space Propulsion to Take Us to Mars and Beyond Faster

Costa Rican physicist, Franklin Chang Diaz, is the founder of Ad Astra Rocket Company, and the inventor of VASIMR, the Variable Specific Impulse Magnetoplasma Rocket. NASA calls this the engine that does matter. The meaning can be interpreted several ways. The engine converts matter into a plasma to create thrust. And the engine matters because if successful testing to be completed this year proves the technology is viable, it may become the way NASA moves satellites and humans around once they get into space. Ad Astra’s headquarters is in Liberia, Guanacaste, in the dry northwest of the country.

When Andy Weir wrote his book, “The Martian,” he featured VASIMR as a technology that would get humans to Mars. Chang Diaz is a graduate of MIT and an astronaut who has served on the International Space Station and the Space Shuttle over several decades.When he retired from NASA in 2005 to form Ad Astra with the goal of designing an engine that would reduce the time to get to Mars and other places in the Solar System much faster. VASIMR, claims Chang Diaz will get astronauts from Earth to Mars in 39 days versus 6 to 8 months by chemical propulsion.

VASIMR is a hybrid technology that requires a power source to heat the matter injected into it to create plasma. The hybrid options for a trip to Mars could be large solar panels or a small nuclear reactor. This year the plan is to demonstrate VASIMR in a 100-hour continuous operation generating 100-kilowatts. If successful with this prototype, this Costa Rican company will, in the very near future, be the engine of choice for exploring the Solar System.

NASA Makes Investments in Deep Space Propulsion Technologies https://techsomogro.com/nasa-small-investments-generation-deep-space-propulsion-technologies/?utm_source=rss&utm_medium=rss&utm_campaign=nasa-small-investments-generation-deep-space-propulsion-technologies https://techsomogro.com/nasa-small-investments-generation-deep-space-propulsion-technologies/#respond Tue, 07 Apr 2015 20:29:35 +0000 http://www.21stcentech.com/?p=16889 April 7, 2015 – NASA last week announced its NextSTEP 12 space technology commercial partnerships focused on helping to advance key technologies to move us here on Earth deeper into the cosmos. Each of the companies is receiving annual grants of between $400,000 and $3.5 million U.S. for a three-year period.

Divided into three categories, NASA hopes to see progress in the following areas:

  1. Advanced propulsion systems.
  2. Space habitation.
  3. CubeSat projects.

In this posting we will discuss only those technologies focused on point #1, advanced propulsion systems. In subsequent blogs we will address the other two.

In a nut shell the problem NASA faces is one of distance and time. To get to Deep Space it needs faster, more portable and long-duration propulsion technologies that present alternatives to using traditional chemical-fueled rockets and thrusters. In all robotic missions to the Solar System’s many destinations, save a few, NASA has been relying on chemical-fueled propulsion. Because launching from the gravity well of Earth limits the amount of propellant within a payload NASA and its mathematicians have supplemented the chemicals with the clever use of the objects in the Solar System itself using their gravity to accelerate spacecraft to get from Point A to Point B. Flights using gravity assistance take years to get to their ultimate destinations with the spacecraft looping through the Solar System, aerobraking in the upper atmosphere of planets, all to alter trajectory and gather speed.

It is clever and efficient but a death sentence if it were to be used for human missions. Human crews would not survive such multi-year transits for many reasons (water, air, food, cosmic rays, etc.) NASA, therefore, is looking to commercial partners to help it perfect alternative propulsion to move them faster and further while minimizing risk to human crews.

In last week’s announcement NASA provided three-year funding contracts to companies that have shown they have the “right stuff” to help get to Deep Space. These companies include:

  • Ad Astra Rocket Company, Webster, Texas, developers of the VASIMR (R) engine. VASIMR is an acronym for Variable Specific Impulse Magnetoplasma Rocket, an electric rocket engine that takes gases such as argon, xenon or hydrogen and superheats them to create a hot plasma that when ejected through the rocket bell creates thrust. The schematic below is the VX 200 prototype, the type of engine that could power a flight to Mars. VASIMR technology can be combined with solar power arrays for use in near-Earth, sub-lunar settings. But for Deep Space missions it can be combined with a small nuclear reactor to generate electricity and dramatically increase thrust. Firing a VASIMR engine continuously for a lengthy burn when attached to a nuclear power source would be not only sustainable but also reduce a flight to Mars from 6 months to 39 days. Hence NASA’s interest.

 

VASIMR engine

 

  • Aerojet Rocketdyne Inc., Redmond, Washington, has partnered with NASA in developing landing technology for the Martian rover Curiosity, and is now being assigned the task to further develop the NASA Evolutionary Xenon Thruster, or NEXT. A Xenon thruster was used by the Dawn robotic spacecraft to provide power on its voyage to asteroids Vesta and Ceres. Ion propulsion doesn’t produce a lot of thrust but cumulatively over time can accelerate a spacecraft to the very high speeds needed to make it to destinations like Jupiter, its moons, and the Asteroid Belt. Its limitation is the dependency on sufficient sunlight to generate the electricity needed to power the thrusters. Aerojet has been tasked with tripling that thrust capability as well as developing more advanced power processing units capable of increasing the energy conversion efficiency from the solar panels to the thrusters.

 

Xenon thruster

  • MSNW LLC, Redmond, Washington, is developing the Electrodeless Lorentz Force (ELF) thruster, a steady-state pulsed inductive propulsion system. It operates with rotating magnetic fields to create field-reversed plasma toroids and can utilizes almost any in situ fuel from liquid water to hydrazine to the air of Mars. It is the ultimate engine for Deep Space missions if the technology can be improved to increase the power conversion to thrust yield. This is the assignment NASA is funding.
