AUSTIN, Texas — For Brett Hagler, the co-founder of non-profit New Story, building homes for people without adequate shelter is nothing new."We get a large piece of land and work with families that have been living in shacks or tents without shelter and design a totally new community with the families.”Approximately one billion of the world’s population is without proper shelter.To make a dent in that he says, they have to think outside the mold.“We believe traditional ways cannot get us there.”So for New Story’s next endeavor—adding more communities to the land they’ve already acquired in El Salvador—they teamed up with a brand new startup.That’s where Evan Loomis comes in. He’s the co-founder of Austin, Texas-based Icon, a company focused on new technologies for building homes.Their first big debut came at this year’s South by Southwest festival in their hometown.“This is a gigantic robot,” Loomis says, gesturing toward a large steel frame on wheels. “[It] really does some amazing things. Down to the millimeter it knows exactly where to place building materials.”In this case that material is a proprietary mixture of concrete, that pours out of a nozzle on the underside of the metalwork. And the machine moves along a computerized map to create a house.“This is basically the first permitted 3D printed house in the United States,” he said.“We have to invest in [research and design],” Hagler said. “[We asked ourselves] ‘how do we get a breakthrough in cost, speed, and quality?’ And that’s how we landed upon 3D-home printing. The excitement in the air is palpable as they walk us through and around this modest home built up of about 100 one-inch thick concrete layers.“It’s stronger than regular cinder block,” Hagler said. It also comes at a fraction of the cost of a regular house. This model had a price tag of about ,000 but they hope to get the price down to ,000.“We can build in a fraction of the time [compared to traditional construction methods], and it can have a higher quality, strength, and sustainability for the environment."It was 'printed' in just 48 hours. Eventually, they say it will be done in just a half day. It’s a small but open floor plan — with no physical doors — and rooms are separated by partial walls made up of the printed concrete.They say they’ll easily be able to customize different designs.The prototype home can fit a family of four or five.“If you’re coming from a tent or shack and you move into this,” Hagler said, “it’s a significant life-changing difference.”One of the things they’re most excited about with their upcoming 3D-homes project in El Salvador is the fact that they’re introducing groundbreaking technology to the people who usually see tech advances last.“We are actually bringing them the future -- which is robotic construction of housing — first,” Hagler said. “And they’re really excited about that.”They say they plan to begin construction in El Salvador before the end of the year with the hopes of finishing their first community of homes by early 2019. There could one day be plans for 3D printed homes in some of the poorest areas of the United States as well, Loomis said, but he has his eye set on possibly expanding to terrain that’s literally out of this world.“It could be a really great solution for making space habitation a lot more achievable,” Loomis said. “We hit a nerve with this technology, and we are going to hit the gas hard and try to take it to everybody now.” 3528

As part of his push to get schools reopened in the fall, he is calling on Congress to approve 5 billion in funding to help with additional costs associated with the coronavirus pandemic.“This funding will support mitigation measures such as smaller class sizes, more teachers and teacher aides, repurposes spaces to practice social distancing, and crucially mask wearing,” Trump said.Trump is also taking a different tact to compelling schools to reopen. Previously, Trump threatened to pull federal funds from schools that did not reopen. Many of those funds are through the Title 1 program, which are directed toward poorer and disadvantaged schools.Rather than pulling federal funds from schools that opt for virtual learning, Trump said that the supplemental funds would go with the students. Under his proposal, students could use federal funds for other in-person learning options, or for homeschooling.“If schools do not reopen, the funding should go to parents to send their child to public/private, charter, religious or home school of their choice, the keyword being choice,” Trump said. “If the school is closed, the money should follow the student so the parents and families are in control of their own decisions. So, we would like the money to go to the parents of the student. This way they can make the decision that's best for them.”Trump said that the CDC would issue new guidance Thursday evening on how to safely reopen schools.While Senate Republicans seem poised to pass additional education funds as part of a broader stimulus plan, Democrats are not as enthusiastic.Speaker Nancy Pelosi told reporters on Thursday that the bill “so far falls very short of the challenge that we face in order to defeat the virus and to open our schools and to open our economy.”The bill also includes funding for coronavirus tests and a second round of stimulus checks. 1887

At least 48 people were shot within a 24-hour span on Sunday in New York, capping off a violent Fourth of July weekend, police said.Among those shot, 10 of them were fatal.Since Friday, there were 63 victims of gun violence, continuing the rising trend this summer.Most of the shootings were on Sunday, though there were a number of incidents on Saturday, including one in which no one was hurt. Police opened fire in Astoria, Queens on Saturday night when they spotted an individual shooting at someone else. A suspect was taken into custody in that incident.Police also witnessed violence first hand outside the 40th precinct in the Bronx Saturday night. A bullet pierced the front window of their marked cruiser.While in Brooklyn, a flaming firecracker was tossed inside a patrol car with an officer sitting inside.In a pair of tweets from Manhattan police commanders, the chiefs called out city leaders, saying the city is under attack, and they are demanding action.Former police commissioner Ray Kelly criticized Mayor Bill de Blasio for limiting anti-crime units as “crime is raging out of control in New York City.”Police are searching for suspects in multiple shootings.According to the NYPD, there were 575 incidents with 705 victims from Jan. 1 through July 4 of 2020. There were 369 incidents with 423 victims in the same time period last year. Sunday, the NYPD Chief of Detectives, Rodney Harrison tweeted, “The NYPD and the community need to work together as a team to help curb the violence.”Contributing reporting by Jennifer Bisram and Magee Hickey.WPIX's Anthony DiLorenzo first reported this story. 1625

  

At least 452 people were killed and thousands injured after a powerful earthquake struck near the border of Iran and Iraq late Sunday.The 7.3-magnitude earthquake is the deadliest of the year, eclipsing the one that hit Mexico City in September, and was felt as far away as Turkey and Pakistan. 302

  

As the debate rages nationwide over what to do over a plethora of Confederate monuments, new concern is mounting over a Confederate rally planned for Richmond, Virginia, on Saturday.At the center of the debate is Richmond’s “Monument Avenue,” a collection of statues of Confederate leaders in the former Confederate capital. Back in May, the city’s mayor Levar Stoney said that while he personally believes the monuments are an “endorsement of a shameful past,” he didn’t believe there should be a rush to remove them. He had hoped for a dialogue to take place, and even floated the idea of adding plaques to the statues for more accurate historical context."I think we have an opportunity here in the city to actually be a hub for reconciliation."He created the “Monument Avenue Commission” and even solicited public input in the form of open public meetings. Richmond residents were not shy voicing their opinions.Rita Willis, a former teacher, attended the Aug. 9 public forum to say they are a part of Virginia’s history, whether some like it or not. However she emphasized that if they stay, other statues should be erected that highlight people of other races and ethnicities.George Knight, on the other hand, stood in the auditorium and gave city officials a tongue lashing.“Now is the time to finally get rid of the monuments and replace them with people who actually fought for freedom who actually stood for justice,” Knight said, his voice raising as officials urged him to keep calm. “You lost! Get over it already! Get rid of your participation trophies on monument avenue, get rid of it.”He was met with a spattering of boos as well as cheers.But some attitudes regarding the statues changed following the white nationalist rally last month in Charlottesville, Virginia, which culminated in counter-protestor Heather Heyer losing her life. Stoney is one who’s taken a slightly different position since Charlottesville and believes that perhaps they should now consider taking them down. He wrote in a statement that it had become clear that the statues were being used as a “rallying point for division and intolerance and violence.”The group rallying support around the Robert E. Lee statue on Saturday is a relatively small group out of Tennessee known as “CSA II: The New Confederate States of America.” The group’s president said they were “standing up for their proud heritage” in a nonviolent manner and that any white nationalists or racists who show up to rally with them will not be accepted.He said his message to Richmonders on edge regarding the weekend’s rally is simple: “We are here for peaceful purposes only.”“We will not stand for any violence in Richmond, Virginia.”But the city says they are taking protective measures to be safe. The mayor and police chief announced this week that any objects that can be used as weapons will be prohibited. One type of weapon that won’t be prohibited, however, are guns, as Virginia is an open-carry state.“If you do not respect our city,” Stoney warned, “law enforcement will lock you up."  3084
