Former Special Counsel Robert Mueller told Congress on Wednesday that his investigation did not "totally exonerate" President Donald Trump as the President has claimed."The finding indicates that the President was not as exculpated for the acts that he allegedly committed," Mueller said. "It is not what the report said."But beyond that response, Mueller's exchanges with lawmakers were at times shaky, with answers that were often halting and stilted in the face of rapid-fire questions. Mueller frequently referred them back to the report, asked for questions to be repeated and answered with short "true" or "that's correct" responses.Mueller is testifying at the most highly anticipated hearing of the Trump presidency, with the potential to reset the narrative about his two-year investigation into the President's conduct.After weeks of negotiations, twists and turns over Mueller's appearance and a pair of subpoenas, the former special counsel is now answering questions about his probe for the first time before the House Judiciary Committee, and will appear at noon ET before the House Intelligence Committee.The former special counsel's testimony is the closest thing to a make-or-break moment as it gets for Democrats in their investigations into the President. It's a potential turning point for the House Democratic impeachment caucus that's banking Mueller can reset the conversation about the special counsel investigation and convince the public -- and skeptical Democratic colleagues -- that the House should pursue an impeachment inquiry into Trump.Democrats have pointed to Mueller's report as a reason to take up impeachment, but he declined to engage on the question."Is it true that there's nothing in Volume II of the report that says the President may have engaged in impeachable conduct?" asked Rep. Jim Sensenbrenner, a Wisconsin Republican."We have studiously kept in the center of our investigation, our mandate," Mueller responded. "And our mandate does not go to other ways of addressing conduct. Our mandate goes to what — developing the report and turning the report into the attorney general."Democrats walked Mueller through the key passages of his report, while Republicans sought to undercut the special counsel investigation, raising questions about his decision to write a lengthy report about the President's conduct when he did not decide to prosecute the Trump on obstruction of justice."Volume two of this report was not authorized under the law," charged Rep. John Ratcliffe, a Texas Republican and a former prosecutor. "I agree with the chairman, this morning, when he said Donald Trump is not above the law. He's not. But he damn sure shouldn't be below the law, which is where this report puts him."In his opening statement, Mueller defended the work that his team did."My staff and I carried out this assignment with that critical objective in mind: to work quietly, thoroughly, and with integrity so that the public would have full confidence in the outcome," Mueller said.But Mueller also telegraphed that he would not engage on many of the questions both Democrats and Republicans will want him to answer, from the origins of the investigation to how he decided whether or not to prosecute the President."As I said on May 29: the report is my testimony. And I will stay within that text," Mueller said.Even if there isn't a bombshell revelation, Democrats are hopeful that the recitation of the key points of Mueller's investigation and what it uncovered about the President can move the needle."Although Department policy barred you from indicting the President for this conduct, you made clear that he is not exonerated. Any other person who acted this way would have been charged with a crime. And in this nation, not even the President is above the law," House Judiciary Chairman Jerry Nadler said in his opening statement."We will follow your example, Director Mueller. We will act with integrity. We will follow the facts where they lead. We will consider all appropriate remedies. We will make our recommendation to the House when our work concludes," Nadler added. "We will do this work because there must be accountability for the conduct described in your report, especially as it relates to the President."But if Mueller's testimony fails to shift the conversation, it could spell the beginning of the end for 4385
Getting from here to there is becoming increasingly more sustainable, in part, by electric cars.“All the cars are getting electrified,” Don Hillebrand, with the Advanced Powertrain Research Facility at Argonne National Labs in Illinois, said. “The minivan and the middle of the road sort of cars and the trucks.”By 2040, more than half of new car sales and a third of all cars on the road across the world are projected to be electric, according to Bloomberg.com.But it raises an important question.“What do you do with these batteries at the end of their life?” Linda Gaines said. Gaines is the chief scientist for Recell Center of Advanced Battery Recycling.“For a long time a lot of us looked at electrification sort of as hype,” Hillebrand explained.Hillebrand works at Argonne National Labs in the energy systems division, focusing on optimizing how energy is used. He sees one big problem in the creation of electric car batteries. “There are not enough fundamental elements that go into batteries for us to make all the batteries we need forever and throw them away when we’re done,” he said.Meaning these elements need to be reused. “The early batteries from 10 years ago are hitting the end of their life,” he said.The global stockpile of these batteries is expected to exceed 3.4 million by 2035, compared to 55,000 in 3018, according to the Institute for Energy Research. Once the battery loses 20 to 30 percent of its capacity, the available driving range gets shorter, so some companies are using them for other purposes.Florida Power and Light is using them for power storage, and Nissan is reusing old Leaf batteries to power Japanese street lights.These companies are repurposing, but researchers think another fix could come in the development stage.“After 10, 15 years, those batteries are going to reach the end of life and we have to do something with them,” Venkat Srinivasan, a battery scientist at Argonne National Labs, said. “We think there are ways in which we can make these batteries last more than 20 years.”And that’s exactly what’s being done inside this facility. The lab he works in is looking into ways to make batteries last longer. But for now, the main focus is on giving them a second life by recycling.“The biggest challenge today in recycling batteries is they’re not economic,” Venkat said.That's where the Recell Battery recycling center and other recycling businesses come into play.“If you can recover the materials in the battery in a usable form,” Linda Gaines explained. “You can actually recover valuable product.” This includes cobalt and other elements. Linda Gaines and Jeff Spangenberger are part of this center. Their goal is to come up with a recycling process that’s profitable.“Some things take more energy and resources to recycle then it did to make them in the first place,” Gaines said. “So, when you’re looking at the whole life cycle of the product, you need to try to figure out what the benefits are and what the costs are to recycle.”To understand size, one pouch cell in an electric car battery is about the size of a tablet. In the generation 1 Chevy Volt there are 288 pouch cells in one battery.Cars have become the biggest user of lithium ion batteries -- even more than consumer electronics, the Institute for Energy Research said.While Recell is looking into ways to make the recycling process more beneficial and profitable, Larry Reaugh with American Manganese, Inc. is doing something similar. “That’s where we come in, we want the battery packs,” Reaugh said. With their process, they are able to recover the elements inside the battery, comparing their operation to a small operating mine.“There’s a lot of money in it, because it’s very valuable material,” he said.As more batteries retire, companies like this will become more important.“There’s a trickle of batteries that are being recycled right now, but there’s gonna be an avalanche of batteries coming in the next 5 to 10 years as cars hit the end of their life,” Hillebrand said. 4027
GENEVA, Switzerland – The World Health Organization has declared the ongoing coronavirus outbreak a pandemic. "WHO has been assessing this outbreak around the clock and we are deeply concerned both by the alarming levels of spread and severity, and by the alarming levels of inaction," said Dr. Tedros Adhanom Ghebreyesus, Director-General of WHO. “We have therefore made the assessment that #COVID19 can be characterized as a pandemic”By definition, a pandemic is an outbreak of a disease that occurs over a wide geographic area and affects an exceptionally high proportion of the population.Ghebreyesus says the number of COVID-19 cases outside of China has increased 13-fold and the number of affected countries has tripled. “There are now more than 118,000 cases in 114 countries and 4,291 people have lost their lives,” said Ghebreyesus. In the days and weeks ahead, experts expect to see the number of cases, the number of deaths and the number of affected countries to climb even higher. "Pandemic is not a word to use lightly or carelessly,” said Ghebreyesu. “It is a word that, if misused, can cause unreasonable fear, or unjustified acceptance that the fight is over, leading to unnecessary suffering and death"Ghebreyesu says describing the outbreak as a pandemic doesn’t change WHO’s assessment of the threat the virus poses or what the organization is doing to combat it.According to Ghebreyesu, some of the hardest hit countries are seeing some progress in the fight against the virus."Of the 118,000 COVID-19 cases reported globally in 114 countries, more than 90 percent of cases are in just four countries, and two of those China and South Korea, have significantly declining epidemics," said Ghebreyesu.
