Pyka Bets The Path To The Future Of Passenger Planes Runs Through Banana Plantations In Latin America

Pyka Bets The Path To The Future Of Passenger Planes Runs Through Banana Plantations In Latin America

Pyka’s Pelican crop-spraying drone can carry more than its weight in chemicals and is designed to take off and land in 150 feet, half the length of a football field.

 COURTESY OF PYKA

Oakland-based Pyka shares a goal common to many high-tech California aviation startups: to build an autonomous electric passenger aircraft. However, its first steps to get there have taken the company far away from the pack, first to New Zealand and now to banana plantations in Costa Rica and Ecuador, where it’s preparing to field a robotic crop-spraying airplane called Pelican that CEO Michael Norcia says will prove out technology he believes will lead the way to an era of green, low-cost passenger planes.

The fat-bellied, 500-pound plane can carry more than its weight in liquid pesticides or fertilizer, and is engineered to take off and land in a ridiculously short space: 150 feet, half the length of a football field. Someday that short takeoff and landing capability may enable passenger service to be shoehorned into cities and suburbs in a different way than many other electric aviation startups are envisioning. For now, the 28-year-old Norcia is betting that agriculture is a more practical – and lucrative — avenue to pursue. Pyka says the Pelican will have 50% of the operating costs of manned crop-spraying planes and will remove pilots from harm’s way in a business where skimming fields at 140 miles per hour too often leads to accidents and death. And banana plantations, which are the most frequent users of aerial spraying in the world, may be the perfect environment for it to take wing.

Dozens of companies are trying to build futuristic-looking, autonomous electric “air taxis” that can take off and land vertically on city roofs, carrying one to a half-dozen passengers. Norcia, whose first job after graduating from UC Davis with a physics degree was at one of them, billionaire Larry Page’s Kitty Hawk, believes they’re a decade too soon – the limitations of current batteries and other technologies leave eVTOLs with too little range given how energy intensive it is to propel an aircraft straight up and down, he says.

Pyka’s strategy is to take the well-understood efficiencies of fixed-winged airplanes and marry it to advances in high-power electric motors to produce an airplane that can operate on radically shorter runways. “They like to fly,” Norcia says of fixed-wing airplanes. “By starting with something that looks like an airplane you start off on the right foot.”

Crop-spraying planes hug the ground in rural airspace that no one else is using, meaning Pyka doesn’t have to solve the thorny problems that drone package delivery services and autonomous urban air taxi hopefuls do of how to ensure their aircraft don’t crash into each other, or the airplanes and helicopters that already fill suburban and urban skies.

Another reason Norcia says they “fell in love” with crop spraying: profit potential.

“The unit economics are fantastic, stronger than any other use case we looked at,” says Norcia, including passenger service or cargo delivery, which a number of other startups are focused on as a more practical near-term target.

Pyka, which has raised $11 million from backers including Prime Mover Labs and Y Combinator, declined to discuss the numbers behind its analysis, but Norcia says of all crops, bananas offer the company the most fertile environment.

Just one variety, the Cavendish, accounts for 99% of the world’s banana exports; grown in Latin America on vast plantations that are susceptible to getting wiped out by funguses, the 15-foot-tall plants are sprayed aerially on a weekly basis. That will keep Pelican busy on the same fields, which is key for it be competitive now.

Before it can start spraying, Pelican’s operators have to survey the field, pinpointing boundaries and obstacles like telephone wires or irrigation towers that the plane will have to avoid. Down the road Norcia says Pelican, which is equipped with downward-facing Lidar and forward-facing lasers, will be able to map fields in 15 minutes, but for now it takes three hours, which means it’s not time or cost-competitive with manned aircraft unless the field needs frequent spraying.

That’s a lesson Pyka learned through experience in New Zealand, where it’s already sprayed crops with a smaller, earlier-generation version of its plane called Egret that the company says is the largest UAV yet to be used commercially. Pyka set up shop there due to a more experimentation-friendly regulatory environment that first attracted Norcia’s former employer Kitty Hawk, which has been flight-testing a two-seat autonomous aircraft in New Zealand since 2017, now in partnership with Boeing.

 COURTESY OF PYKA

But worried that safety certification from New Zealand aviation authorities for such new technology wouldn’t be recognized in other countries, Pyka decided to shift to the U.S. for certification. The U.S. Federal Aviation Administration granted Pyka a special airworthiness certificate for Pelican two weeks ago that allows the company to start demoing it on farms in the U.S. and to train crews here on how to operate the airplane, which the company plans to lease to aerial spraying outfits. Norcia expects to receive full-fledged certification from the FAA by the end of the year to spray fields within line of sight of a safety monitor, which should allow the company to get under way at the banana plantations, given reciprocal recognition by those countries’ aviation authorities.

In the U.S., the largest aerial spraying market in the world with roughly $800 million in annual sales, by the estimate of the National Agricultural Aviation Association, drones have caught on for monitoring the health of crops, but not for applying pesticides, due to crop-spraying drones’ high cost and limited capacities. Pyka sees opportunity with crops like leafy greens and vegetables that need to look good on supermarket shelves – those often are sprayed five to 15 times a year, says Norcia.

Norcia concedes that Pelican will only be 40% as productive as the average manned crop-spraying plane, which carries roughly six times as much chemical as the 625-pound payload electric drone, and traverses fields at much faster speeds (140 mph vs. 80 mph for Pelican) but he says the electric drone will make up for it on the cost side. “It’s an order of magnitude less expensive per hour to run,” he says. Plus he says the robot will be able to apply its payload more accurately and efficiently than a human pilot, flying safely at night, when winds are often gentler, and minimizing drift, which would limit the chemical exposure of people who live by farms.

Andrew D. Moore, CEO of the National Agricultural Aviation Association, says his members will embrace any technology that makes them more efficient, but he says the jury is still out on how precise crop-spraying drones are given the air flow impact of their multiple rotors. The agricultural aviation industry has worked with the EPA for decades to reduce drift and optimize how single-propeller airplanes dispense chemicals, he says, intensively studying their aerodynamics and how to align spraying booms and nozzles. “When claims are made about the precision of UAVs, the research is not there,” Moore says.

Norcia says the design flexibility allowed by lightweight electric motors has enabled Pyka to place its three propellers – one high up on Pelican’s T tail and one on each wing — where they have no measurable impact on the drone’s spray pattern, which he says they’ve studied with top researchers in the field.

Damon Reabe, a third-generation crop sprayer who runs two businesses in Wisconsin that operate eight single-prop Air Tractor AT-502s and a helicopter, says Pyka isn’t taking account real-world problems that may torpedo its efficiency claims.

Pyka says Pelican is capable of spraying 135 acres an hour, landing every 15 minutes to refill its tank and with a battery swap after 45 minutes. Reabe says that means he’d need at least three of the drones to cover the same amount of ground in an hour as he can with a single Air Tractor. Given that each Pelican requires a crew of two (a remote pilot and a ground station operator) and a truck to haul the drone, chemicals and water to the field, Reabe says it sounds like “a logistical nightmare.”

Three trucks means recruiting three workers who hold commercial drivers’ licenses, who Reabe says are tough to recruit for seasonal work, as well as training more people on how to mix and handle the chemicals. And they all have to show up on time in order to get out to the farm for a full day’s work.

Once there, Reabe says it may be harder than Pyka realizes to find space for all that equipment on a busy farm, as well as for Pelican to take off and land, something he says he knows well from his helicopter operation, which also operates from a truck on site.

“I don’t want to disparage their efforts, but there are other problems that need to be solved,” says Reabe, “and once you do that you don’t know that it’s less expensive than putting the pilot in the aircraft.”

Norcia says Pyka’s efficiency case will be bolstered once it’s certified to fly beyond the pilot’s visual line of sight, and down the road a single pilot should be able to oversee multiple Pelicans.

The company says they have a three-year backlog covering the first 80 Pelican deliveries to agriculture aircraft operators.

Other startups are exploring the potential of short-takeoff-and-landing (STOL) airplanes: Electra.aero, founded by UAV pioneer John Langford of Aurora Flight Sciences, is developing a hybrid STOL passenger plane, while Marc Ausman, the chief strategist for Airbus’ shuttered Vahana eVTOL project, is heading a venture called Airflow that aims to build an electric STOL cargo plane.

Coinciden Trump y Biden en pronta reapertura de escuelas en EUA

Trump le pidió explicar supuestas irregularidades en relación a negocios de su hijo Hunter Biden.

Joe Biden y Donald Trump se enfrentaron este jueves en el último debate antes de las elecciones presidenciales del 3 de noviembre y coincidieron en la pronta reapertura de escuelas en Estados Unidos cerradas por los contagios de COVID-19.

En el debate ocurrido en la universidad de Belmong en Nashville, ubicada en Tenneseee, el demócrata señaló que creará estándares nacionales para abrir escuelas y comercios. “Voy a encargarme de esto, de asegurarme que tengamos un plan. El no tiene uno”, explicó.

En tanto Trump argumentó que deben abrirse ya que “la tasa de transmisión entre los jóvenes es muy leve. Yo quiero abrir las escuelas, no se puede cerrar el país”.

Trump cuestionó a su rival y le pidió explicar supuestas irregularidades de cuando era vicepresidente entre 2009 y 2017 en relación a negocios de su hijo Hunter Biden.

“Nunca he recibido ni un centavo del extranjero en toda mi vida”, respondió a los señalamientos de los negocios de su hijo en Ucrania y China que el magnate catalogó como “un caso de corrupción importante”.

Biden por otra parte, criticó la política de Cero Tolerancia en 2018 en la que se separó a niños migrantes de sus padres.

“Esos chicos están solos, sin lugar a donde ir. Eso es criminal”, dijo Biden sobre los 545 menores de los que aún no se localiza a sus padres.

My Student Experience: Mathematics Education Student Jessica Terrones ‘22 Shares Her ‘Sin Limite’ Experience as Latinx Heritage Month Committee Chair

My Student Experience: Mathematics Education Student Jessica Terrones ‘22 Shares Her ‘Sin Limite’ Experience as Latinx Heritage Month Committee Chair

“Sin limite.” In Spanish, the phrase means “limitless.” For Jessica Terrones ‘22, who helped choose those two words as the theme for this year’s Latinx Heritage Month, it means a world of possibilities.

“As a daughter of immigrants, I have always felt that I had limitations, such as fears of proving myself because of the color of my skin or being frowned upon for the way I speak,” Terrones said. “It never felt like I could ever overcome such limitations until now. I know that I am more than capable, and I am willing to continue to persist without fear of what others think of me.”

That confidence comes in part from her role as this year’s NC State University Latinx Heritage Month committee chair. As the committee chair, the number of tasks she needed to complete to make sure the month went off without a hitch came close to pushing her to her limits.

In addition to helping select the theme, she recruited students to the planning committee, decided on programming, organized marketing materials and served as the committee’s liaison to other student organizations. But Terrones was up to the challenge, thanks to her experiences with Professional Learning Teams (PLT) as a mathematics education major in the College of Education.

“I had to regularly communicate with my committee members and let their voices be heard,” Terrones said. “I had never been in charge of a group or event so large as Latinx Heritage Month, but many of the skills like public speaking, PLT techniques, cultural competence and more that I attained through the College of Education helped me successfully lead and take charge.”

Terrones first volunteered with the Office of Multicultural Affairs to fulfill the College of Education’s Passport to Success cross-cultural signature experience, but that experience soon turned into a job opportunity that eventually led to her taking a leadership role as the chair of the Latinx Heritage Month committee.

For Terrones, the month, which lasted from Sept. 15 to Oct. 15, is a vital opportunity to let students know their heritage is being recognized.

“As a person of color at NC State, it can be easy to feel intimidated for standing out in a predominantly white institution,” Terrones said. “So by having Latinx Heritage Month, it at least gives students a moment to feel heard and acknowledged, even if it’s for a month.”

And it’s not just about being heard and acknowledged, but about bringing people together.

“It lets students know that there is a community out there where they can feel accepted and can relate their experiences while continuing to learn about one another,” Terrones said.

To create these learning opportunities, Terrones and the rest of the committee planned a variety of events, including “Mi Cocina” cooking videos on Instagram, a keynote speaker series and a virtual educational gallery. Planning these virtual events was a challenge, but Terrones knew it was necessary.

“We had seen with our own eyes that Latinx people had been one of the most impacted groups by the pandemic, so we could not risk endangering the lives of our peers as much as we wanted to do in-person events,” Terrones said.

Normally, there is only one keynote speaker during the month, but Terrones and her committee wanted to demonstrate how intersectional “sin limite” could be.

“You can be Latinx and have a career in STEM,” said Terrones. “You can be a librarian and a DJ. You can connect with your ancestral roots while encouraging underrepresented groups to engage with the outdoors. There is no one who fits all views on how a Latinx person should be in 2020, so we used this thought to guide our selection of keynote speakers.”

A self-described introvert, Terrones overcame her fear of public speaking in order to step into her leadership role.

“I had to lead keynote speaker events and committee meetings, which were very intimidating, but I enjoyed that they challenged me to do better,” she said.

Latinx Heritage Month enabled Terrones to transcend her limits, but it also allowed her to stay grounded.

“Through my experience, I have been able to stay connected with my identity,” Terrones said. “Coming into college, I was scared of losing that part of me, but instead, I have been able to embrace it.”

Race For COVID-19 Vaccine Gets Hotter

Race For COVID-19 Vaccine Gets Hotter

Dozens of companies, from biotech start-ups to Big Pharma, are racing to develop a safe and effective COVID-19 vaccine, because the world needs it and for the potential pay day.

Here’s an update on the quest for a magic bullet against the coronavirus that has already killed more than a million people worldwide.

How Many In The Pipeline? 

The World Health Organization (WHO) has identified 42 «candidate vaccines» at the stage of clinical trials, up from 11 in mid-June.

10 of them are at the most advanced «Phase 3» stage, in which a vaccine’s effectiveness is tested on a large scale, generally tens of thousands of people across several continents.

United States (US) biotech firm Moderna, a US-German collaboration between BioNTech and Pfizer, several state-run Chinese labs, and a European project led by the University of Oxford and AstraZeneca are thought to be among the more promising.

Russia has already registered two COVID-19 vaccines, even before clinical trials were completed.

American pharmaceutical giant Pfizer said on Friday it would apply for emergency authorisation in the US for its vaccine in late November if safety data pans out.

Other clinical trials are still in Phase 1 or 2, while another 156 are in pre-clinical stages of development.

What Kind Of Vaccines? 

Some methods for making a vaccine are tried-and-true, while others remain experimental.

Inactivated «classic» vaccines use a virus germ that has been killed while others use a weakened or «attenuated» strain that is virulent enough to provoke antibodies but not to cause disease.

So-called «sub-unit» vaccines contain a fragment of the pathogen that it is derived from to produce an appropriate immune response.

«Viral vector» varieties use other forms of live virus to deliver DNA into human cells, triggering an immune response.

A measles virus modified with a coronavirus protein, for example, can be deployed against COVID-19.

There are also experimental gene-based vaccines using DNA or RNA fragments.

What Are The Results? 

To date, only the result of Phase 1 and 2 trials have been published in peer-reviewed medical journals.

On Friday, preliminary results showing that a vaccine developed by Chinese firm Sinopharm provoked an immune response were published in The Lancet.

Similar studies in recent weeks have reported on one of the Russian vaccines, along with those from the University of Oxford, Chinese company CanSino, and Moderna.

While encouraging, it is too soon to say whether these vaccines will pan out. Trials of two candidate vaccines – made by Johnson & Johnson and Eli Lilly – were «paused» recently over safety concerns.

But that is not necessarily bad news, said Stephen Evans, a professor of pharmacoepidemiology at the London School of Hygiene and Tropical Medicine.

«The fact that trials are paused should indicate that there should be confidence that the whole process of monitoring the safety of trial participants is working well,» he said.

Recent cases in which recovered COVID patients were infected a second time with a new strain also raise the question of how long vaccines might last.

Speed Vs. Safety 

Companies backed by their governments in China, Russia and the US are racing to be the first across the finish line.

In early August, Russian President Vladimir Putin declared victory, announcing the roll-out of the Sputnik V vaccine before Phase 3 trials had begun.

But there were few takers outside of Russia, and experts dismissed the announcement as premature.

Donald Trump has promised a vaccine before the 3 November election, but it is unlikely he will be able to deliver.

Earlier this month, the US Food and Drug Administration (FDA) said it would need to see two months of follow up data after vaccination before giving emergency authorisation for use.

And on Friday, Pfizer said its vaccine wouldn’t be ready until mid-November.

«What is different for COVID-19 vaccines is that speed of development and potential approval is much faster due to the public health emergency,» noted the European Medicines Agency (EMA).

But even that pressing need cannot overcome the rules.

«Before approval, all vaccines in the European Union (EU) are evaluated against the same high standards as any other medicine,» the EMA said in a statement. – AFP

Estados Unidos: Deportation Fear Grips Latino Students

Deportation Fear Grips Latino Students

When President Donald Trump took office in 2017, immigration advocates and school officials braced for the prospect that he would undertake  unprecedented immigration enforcement measures that could upend the lives of millions.

Nearly four years later, the nation’s Latino schoolchildren are bearing the mental and psychological brunt of the president’s campaign to curtail immigration: A majority of Latino high school students in two states fear that someone close to them could be arrested and deported, a new Migration Policy Institute study reveals.

More than half the students surveyed in both Rhode Island and Texas, states with vastly different immigration enforcement climates,…

Estados Unidos: CPS presenta plan tentativo para el regreso a clases en persona

América del Norte/Estados Unidos/18-10-2020/Autor(a) y Fuente: www.telemundochicago.com

El plan propone que la población estudiantil en general continúe recibiendo educación remota y por fases regresen gradualmente a los salones de clases.

Las Escuelas Públicas de Chicago anunciaron el viernes un plan de aprendizaje para el segundo trimestre del año escolar a medida que continúa la pandemia del coronavirus.

El plan del distrito propone que todos los estudiantes continúen sus clases de forma remota y luego por fases vayan regresando gradualmente a los salones de clase.

CPS dijo en un comunicado que planea comenzar su reapertura gradual a las escuelas con los «estudiantes de prekínder y alumnos vulnerables, como los de educación especial o aquellos que enfrentan desafíos significativos al participar en el aprendizaje remoto sin el apoyo de un tutor, hecho que agrava aún más las desigualad educativa».

 

Los estudiantes seleccionados comenzarían a regresar al salón de clases en enero mientras que CPS pone en función los procesos necesarios de salud para reabrir las escuelas de manera segura.

El distrito planea comunicarse con los padres de los estudiantes de otros grados a finales de este año para evaluar su interés en que sus estudiantes regresen a las escuelas.

CPS dijo que enviará a todos los padres y tutores de estudiantes de prekínder y de programas de grupo un formulario de intención el 21 de octubre para indicar si se sentirán cómodos enviando a sus hijos a la escuela, pidiéndoles que lo devuelvan antes del 28 de octubre.

El distrito señaló que los padres tendrán la opción de optar por no participar en cualquier momento y que cada escuela llevará a cabo una reunión para responder cualquier pregunta antes de una posible reapertura.

CPS dijo que una decisión final sobre el aprendizaje en persona se tomaría junto con el Departamento de Salud Pública de Chicago más cerca del comienzo del segundo trimestre, el 9 de noviembre.

El liderazgo del Sindicato de Maestros de Chicago (CTU) de inmediato reaccionó a este plan tentativo de CPS y dicen que les preocupa el que estas decisiones se tomen cuando han comenzado a aumentar de nuevo los casos de coronavirus en Chicago.

Por su parte, CPS indica que están desarrollando protocolos sanitarios en las escuelas que incluye el uso de cubrebocas, gel antimaterial y lavado de manos constante, además buscan hacer grupos pequeños de estudiantes, que siempre trabajaran juntos, para minimizar interacciones y el rastreo de contactos.

Estados Unidos: Sube 82 % número de inmigrantes en universidades en los últimos 20 años

Los estudiantes universitarios son más propensos a provenir de familias inmigrantes que en los últimos veinte años, según el Instituto de Política de Migración (MPI, por sus siglas en inglés).

La matrícula de estudiantes de origen inmigrante aumentó de 2.9 millones en 2000 a 5.3 millones en 2018, lo que representa un aumento del 82 %.

En cambio, la inscripción de los que no proceden directamente de un entorno inmigrante aumentó sólo un 15 %.

Las universidades ven un aumento de estudiantes con orígenes de inmigrantes

Estos estudiantes representaron alrededor de 5.3 millones (28 %) de los 19 millones de estudiantes universitarios matriculados en 2018, lo que representa un aumento respecto al 20 % en 2000.

Sin embargo, algunos estados reportan un mayor porcentaje de estudiantes con raíces inmigrantes: 50 % de todos los estudiantes que buscan diplomas en California; 40 % en Florida, Hawái y Nevada; 39 % en Nueva York; y 36 % en Nueva Jersey.

El informe excluye a los estudiantes internacionales, que provienen del extranjero específicamente con fines de estudio, para permitir un enfoque en los residentes establecidos de Estados Unidos que están en el país para más de una educación.

La mayoría de los estudiantes universitarios con orígenes de inmigrantes son ciudadanos

Basándose en el análisis de MPI de los datos de la Encuesta de Población Actual de la Oficina del Censo y otras fuentes, una nueva hoja informativa ofrece un perfil de estudiantes universitarios que son inmigrantes (primera generación) y los hijos nacidos en Estados Unidos de inmigrantes (segunda generación).

De los 5.3 millones de estudiantes con origen inmigrante en 2018, el 68 % nacieron en los Estados Unidos. Esto marca un cambio significativo desde 2000.

Del 32 % de los estudiantes matriculados de origen inmigrante que nacieron en el extranjero, la mitad son ciudadanos naturalizados.

Juntos, los ciudadanos naturalizados y la segunda generación representan el 84 % de los estudiantes de origen inmigrante, con titulares de “green card”, migrantes humanitarios e inmigrantes indocumentados que representan el resto.

Con los trabajadores de origen inmigrante proyectados para impulsar el crecimiento de la fuerza laboral de los Estados Unidos a lo largo de al menos 2035, el examen de las características de los estudiantes puede ayudar a los colegios y universidades, así como a los responsables de la política educativa del estado, ya que buscan equipar a sus residentes con las habilidades y los conocimientos para satisfacer las demandas cambiantes de las economías locales y estadounidenses”, dijo Jeanne Batalova, analista principal de políticas de MPI.
