Thug Lessons posted:Asinine point. Ignorant at best, maybe deliberate deception. Yes, scientists agree that feedbacks will cause CO2 to increase even after human emissions peak, but they certainly don't agree that they go on forever. The is a clear consensus that a runaway greenhouse effect is not going to happen, a consensus as strong as that the greenhouse effect is occurring at all. What about positive feedback systems like the release of methane from melting permafrost and methane-hydrides in the oceans? How does that play into the runaway scenarios?

Thug Lessons posted:Methane is probably the most misunderstood aspect of climate change by the general public. Methane doesn't even stay in the atmosphere. It oxidizes and turns into CO2 rapidly and all of the methane we're emitting today will be gone in ten years... https://phys.org/tags/methane/ says: Yes: Methane in the atmosphere is eventually oxidized, producing carbon dioxide and water. As a result, methane in the atmosphere has a half life of seven years. But: Methane is a relatively potent greenhouse gas with a high global warming potential of 72 (averaged over 20 years) or 25 (averaged over 100 years). The abundance of methane in the Earth's atmosphere in 1998 was 1745 parts per billion, up from 700 ppb in 1750. Methane can trap about 20 times the heat of CO2. In the same time period, CO2 increased from 278 to 365 parts per million. The radiative forcing effect due to this increase in methane abundance is about one-third of that of the CO2 increase. In addition, there is a large, but unknown, amount of methane in methane clathrates in the ocean floors. The Earth's crust contains huge amounts of methane. Large amounts of methane are produced anaerobically by methanogenesis. Other sources include mud volcanoes, which are connected with deep geological faults, and livestock (primarily cows) from enteric fermentation.

Not to mention the acidification of oceans from the absorption of the increased level of CO2 combined with higher water temperatures killing off corals. And maybe even plankton.

Steven Goddard is a global warming skeptic, regular contributor to WattsUpWithThat (WUWT), and operator of ”The Deplorable Climate Science Blog.” The name “Steven Goddard” is a pseudonym used by Tony Heller, which he confirmed himself in June 2014. Tony Heller describes himself as “an independent thinker who is considered a heretic by the orthodoxy on both sides of the climate debate.” He has degrees in Geology and Electrical Engineering, and lives in Columbia, Maryland. He describes global warming as the “biggest scientific fraud in history.” Steven Goddard is known for a 2008 article in The Register where he posited that Arctic Sea ice is not receding and claimed that data from the National Snow and Ice Data Center (NSIDC) showing the opposite was incorrect. Goddard later issued a retraction on his statement. Goddard operates a blog titled “Real Science”, originally located at Real-Science.com, then at Stevengoddard.wordpress.com (until May, 2016), and now at Realclimatescience.com. Stance on Climate Change “Make no mistake about it, global warming is the biggest scientific fraud in history.” “Global warming is indeed Mann-made, by Michael Mann and James Hansen. But it has nothing to do with climate or science.” “”The 97% consensus quoted daily by Barack Obama is based on a few fraudulent studies of a handful of published papers.” “There is no global warming crisis. There is a crisis of the White House having government agencies manipulate data, in pursuit of their global warming agenda. There is also a crisis of the White House attacking the Bill of Rights in pursuit of their global warming agenda.”

Sunday on CBSs Face The Nation, Secretary of State Rex Tillerson said President Donald Trump would be open to remaining in the Paris climate accord. Tillerson said, The position is being led and developed by Gary Cohn over at the National Economic Council. I think if you recall, the president also said, look, we are willing to work with partners in the Paris climate accord. If we can construct a set of terms that we believe is fair and balanced for the American people and recognizes our economy, our economic interests, relative to others, in particular, the second-largest economy in the world, China. He added, I think under the right conditions, the president said hes open to finding those conditions where we can remain engaged with others on what we all agree is still a challenging issue.

Sent to Steve Jurvetson, who's on Tesla's Board. The opportunity for Tesla in Puerto Rico and the Virgin Islands. This is a chance for Tesla to do good and a long-term business opportunity as well. Electrical rates in the Virgin Islands and Puerto Rico were around 30¢/kwh prior to the hurricane. I understand that Solar City charges 6.66¢/kwh when they own the panels. To make this work, you would need the Tesla Powerwall too. So perhaps this could come in at 12¢ per kwh. Could be great for all. Replacing unreliable electrical grid with residential and community solar in a timely fashion would be an amazing achievement.

hobbesmaster posted:And then you get to sell the solar panels again the next time there's a direct hit from a tropical cyclone! Or not: Antigua's well-built PV systems sustain impact of hurricane Irma Antigua at only 50 km distance from the eye of the storm and well within the devastating display of natural forces suffered less damage, but was affected seriously as well with sustained winds exceeding at times 275 km/h. This devastating natural disaster has even more underlined the importance of a diligent and reliable approach in terms of planning and installing PV solar systems in hurricane-prone regions. Since the clean energy provider PV Energy has already beforehand adapted the design, mounting and structuring of its solar power racking systems and solar panels to the potential risk of hurricanes almost all solar systems designed and installed by PV Energy sustained the devastation through Irma. Designed to withstand hurricanes of up to the category 4, each of the 55 solar power installations on Antigua, ranging from several kWp to the 3 MWp and 4 MWp utility scale installations at the international airport of Antigua and in the Lavington/Bethesda region with a total of 38,000 panels mounted, have survived hurricane Irma without damages or substantial system failures. One of these PV systems, based on a 50 kWp sun2safe hybrid converter, was even able to generate 25% of its maximum expected performance during the worst hours of the hurricane, thanks to its proprietary MPPT tracking algorithm which is able to optimise the production even under extreme weather conditions. "This experience confirms our commitment to supplying tier one equipment only and adopt proven, reliable and diligently calculated and designed engineering solutions", states PV Energy's Chief Technical Officer Thomas Beindorf. Load test for racking systems, ramming depths for the pillars of the substructures as well as reinforced frames and modules are just a few key factors to be considered for planning and installing robust solar energy plants.

hobbesmaster posted:I thought solar city only did rooftop solar, not these types of heavy infrastructure deployments? They are doing some large projects in Australia: Tesla wins bid to build world’s largest lithium-ion battery for South Australia esla CEO Elon Musk promised back in March that his electric car company, which also owns solar energy provider SolarCity, could help the state of South Australia with its routine weather-caused blackout issues. At the time, Musk said Tesla was so serious about the endeavor, he wrote on Twitter that the project could be completed within 100 days of a signed deal or it’d come free of charge. Now, Tesla is getting the opportunity to make good on that promise, as the company has won the government of South Australia’s bid to build what would be the world’s largest lithium-ion battery. Tesla beat out 91 international bidders for the project — perhaps because of Musk’s clout (and proven track record) and his audacious claim to waive the installation fee — to supply South Australia with a 100-megawatt lithium-ion energy storage solution. It would be the largest lithium-ion battery system ever made, and it appears to involve a substantial scaling up of Tesla’s current commercial Powerpack system first unveiled back in 2015.

Not taking credit for this (I sent a message to a member of their board soon after the hurricane), but this is good news. Tesla is shipping hundreds of Powerwall batteries to Puerto Rico Some of them are already on the commonwealth, along with company employees to install them. Tesla is sending hundreds of its Powerwall battery systems to storm-ravaged Puerto Rico. The commonwealth has been almost entirely without power since after Hurricane Maria made landfall on September 20th and tore up its energy infrastructure. Once the storm passed, Tesla started sending hundreds of its standalone power banks, and some have already arrived while more are en route. Powerwalls, first unveiled in 2015, are large batteries designed to store power gathered by solar panels. Tesla sent its own employees to help install units, and is reportedly working with local organizations to find the best locations for the power banks. These could potentially be worked into whatever energy network can be constructed, but there's no timeline for how long it will take to revive the commonwealth's power network. As New Scientist points out, since the entire grid went down, it must be restarted from scratch in a labor-intensive process known as a 'black start'. Meanwhile, a majority of the 3.4 million Puerto Ricans can't refrigerate food, run air conditioning to stave off the Caribbean heat or pump potable water. https://www.engadget.com/2017/09/29/tesla-ship-hundreds-powerwall-batteries-puerto-rico/

Rime posted:I have posted repeatedly in here that recycling batteries amounts to vaporizing them in blast furnaces and recovering very little of the material. Here is an explanation of Umicore’s recycling process for Tesla batteries: The Umicore battery recycling technology is able to save at least 70 percent on CO2 emissions at the recovery and refining of these valuable metals. It does this by creating “products” and “byproducts,” rather than following a mechanical separation process. “Product” is comprised of an alloy that’s refined into cobalt, nickel and other metals. Traditionally, cobalt is used as a metallic powder to harden tools, or a pigment for ceramics. Umicore has developed a process whereby the cobalt (the highest value material in our batteries) is used to make up LCO (lithium cobalt oxide) that can be resold to battery manufacturers. The “byproduct” produced together with the alloy fraction is an environment-friendly slag where the lithium contained in EV batteries ends up. This “byproduct” containing lithium is valorized in different applications, one being construction material. Nearly 5 percent of the global man-made CO2 emissions worldwide are produced by cement manufacturing. Replacing the raw materials with secondary raw materials, and avoiding thermal processing, significantly reduces the CO2 emission and non-renewable resources consumption. With the “byproduct,” the construction industry is able to use this secondary raw material as a more environmentally-conscious alternative. The only other emissions from the recycling process are CO2, water vapor, and dust. The dust makes up about 1 percent of the total output, and goes to protected landfill. In an effort to reuse every possible part of the process, the Umicore facility even sells the electricity created from an on-site combined natural gas generation plant to the copper mine next door, which uses the heat in its smelters. So, lithium battery packs not only save thousands of gallons of gasoline/diesel over the life of the vehicle, it is less toxic than the lead-acid batteries that are in regular cars. Then, at this moment, much of it is being recycled, with the ultimate goal of 100% reusability of Tesla batteries.
