Nonprofit seeks insight from devices left behind by veterans who died by suicide_我的网站

A |     The cell phones, tablets, and laptops left behind by veterans who died by suicide may offer insight that could help prevent future military suicides, according to a nonprofit dedicated to analyzing the data from the devices.Stop Soldier Suicide collects the technology as part of its initiative, "The Black Box Project," which is named after the black boxes found on planes that help determine the cause of aviation incidents."If we could gather novel data from those that have died by suicide, we might be able to recreate the last year of life," Stop Soldier Suicide CEO Chris Ford told ABC News.Veterans are 57% more at risk for suicide than non-military adults and around 6,000 veterans die by suicide each year, according to the Department of Veterans Affairs."I think we can prevent needless suffering and a ton of loss of life," Ford said.That kind of loss is something David McDaniel, whose son Connor died by suicide at the age of 26, knows all too well.Connor McDaniel joined the Army after high school, and, according to David, he appeared upbeat during his deployment to Afghanistan, where he was assigned to protect local villages from the Taliban."Some of his Army buddies told me that he was making them laugh while they were being shelled in Afghanistan," David McDaniel told ABC News.But it wasn't long after Connor came home that David McDaniel says he sensed a shift in his son's behavior to include "more anger, a lot of frustration, a lot of gloominess."On Sept. 1, 2021, David says his son entered a wooded area with a firearm."I start screaming his name as I'm walking up the field. And just then the police, the sheriff's department shows up and they tell me to come back down," McDaniel said.He followed their direction, but on the car ride home, an officer called him and said Connor was dead after he fired upon sheriff's deputies and the deputies returned fire and killed him.Connor's death was determined to be a suicide. The district attorney's office concluded that the officers' actions were justified.While grappling with his son's death, David McDaniel was immediately drawn to the Black Box Project, which uses forensic software to unlock and comb through service members' devices provided by their loved ones to review their activity in the weeks leading up to their suicides.McDaniel works in the tech field and says if the project can find repeated patterns in online searches, they may be able to help others to prevent suicides.For instance, McDaniel says his son searched for SGLI, Servicemembers' Group Life Insurance, before his death. If a veteran were to make a similar search and look up "suicide" in the future, for example, McDaniel suggests it could trigger an ad for Stop Soldier Suicide to pop up and provide resources in the search results.Ford says the nonprofit uses machine learning, a subfield of artificial intelligence, to analyze texts and notes in order to determine sentiment or emotional tone, such as anger or desperation. He says they can also track phone usage of the deceased veterans to monitor their past sleep cycles and trace their past geo-locations."Machines can go through computations a lot faster than humans, and they can find signals that we often miss," Ford said.Since launching the Black Box Project in April 2020, Stop Soldier Suicide has received over 100 devices, Ford said. So far, he says they're seeing three patterns before most of these suicides: more anger, different sleep patterns, and social isolation.Ford's team includes Ph.D.s in clinical psychology and suicide researchers. A scientific advisory committee helps steer where and what to look for on the devices.The findings are still preliminary, according to the nonprofit, but one goal is to help the organization decide where, when, and how to target their own mental health resources, like adding more hotline staff at certain hours and ensuring calls are picked up overnight.When asked about privacy concerns of collecting data, Ford said it's something they think about daily."We don't resell the data. We don't push it out to others. We use it for our own research purposes so that we can best understand risk and then give those devices back to those families intact," Ford said.Current privacy laws do not carry on past death, meaning the next of kin typically gains new authority.Petra Oxford-Jackson, whose veteran husband Anthony died by suicide, says she gave his phone to the organization with the possibility it could save even one life."I truly believe he would have been okay with it, and it's a hard thing for a survivor to give up something so personal as his cell phone," Oxford-Jackson told ABC News.The Black Box Project received $3 million in funding from the Department of Veterans Affairs earlier this year.If you are struggling with thoughts of suicide or worried about a friend or loved one, call or text the Suicide & Crisis Lifeline at 988 for free, confidential emotional support 24 hours a day, seven days a week.。

现在，可能你只需要每天开开车，就能让国家给你承包电费。而利用的，就是一个叫 V2G（ Vehicle-to-grid ）的技术。江湖中传闻说，这是一项电车狙击传统燃油车的 “ 杀手级 ” 技术。很多朋友可能没听过这个名词，其实这技术说白了就是：双向充电。只不过，是指电动汽车对电网充电。也就是，把咱们的电动车，变成一个长了四条腿的充电宝。通过特殊的双向充电桩，把咱们电池里储存的电，反向输送给国家电网。
而咱们在这中间赚的，就是一个 “ 趁火打劫 ” 的差价钱。我们在电价便宜的谷时，给车充好电。然后，在国家电力紧张的时候，反向把车里的电按照峰电价格，卖给国家。国家电网 V2G 服务 ▼
差评君这里给大家算了笔账哈，看看这笔生意做起来到底咋样。咱们就拿 Model X 为例，它的续航版电池容量在 100KWh。假设按照下图的峰谷电价来计算，那么差价平均能到 0.7 元 /kwh。
也就是说，如果汽车电池容量全部用来充放电，在不考虑损耗的情况下，咱们一单能赚到 70 块。

C | 一个月天天充，那可就是 2100。而这还仅仅只是差价本身带来的收入。作为一项全新项目，车企们给出的 V2G 补贴力度，应该也会很劲道。举个例子啊，前段时间，长城汽车就率先建了个 V2G 运营示范点。

D | 而根据它们的说法，车主每个月最多能靠补贴，美滋滋地躺赚两千。长城汽车 GEF6 V2G 示范项目 ▼
不过，肯定有差友会觉得这事不靠谱。因为 V2G 用的充电桩，跟咱们常用的那种不一样。

E | 虽然现在家充桩也不少见了，但是 V2G 用的是改装过的双向充电桩。目前国内能见到的双向桩，基本上全是公共的。也就是说，咱们卖电能赚是肯定能赚了。只不过麻烦的是，我们每次想卖点电，还得满地找桩。
别担心，到这一趴，就是车厂们登场的时候了。车厂除了要改建专门的双向充电桩，还得弄一个非常重要的东西 —— 储能站。就好像超市的储物柜一样，可以帮咱们把电先存起来。

F | 之后，只要利用线上 APP，监测好电费波动，咱们就能在家完成一键出售。

G |
而且，车厂们也会非常乐意去帮咱们做这事。因为对他们来说，建这玩意成本很低。我国对于动力电池的要求非常严格，导致电池的淘汰率也非常高。之前有机构预测说，2022 年会有 42 万吨退役动力电池等待处理。这些车厂们本来就对那些“ 不合格 ” 电池，头疼的很。

H | 每天都会有大量的报废电池，被输送到太阳能或者风能发电站里，被回收用作储能。

I |
现在 V2G 的储能站，正好让电池们完成下岗再就业。车厂不光能处理掉一大批不合格的电池，甚至还可以反向跟车主们要点储电的手续费。

J | 而且，在 V2G 的背后，最着急的可能还是咱们的国家电网。早在 2018 年，电车还没跑利索的时候，国家就在提倡这个玩意了。今年九月份的时候，能源局又出来点了一下。算是出面给 V2G 模式牵头撑腰了。加大新型电力基础设施建设力度。推动新能源汽车与电力系统融合发展，鼓励开展有序充电、电动汽车向电网送电（ V2G ）等技术应用示范。
至于为啥国家也急着搞这个东西，这段时间看各种电力新闻，大家应该也能感觉出来。

K | 电这玩意是真的存不住，只能现发先用。

L | 我国有大量的峰值负荷的备用发电厂，大部分时候都是闲置的。有且仅有缺电的时候，这些电厂才会运作起来。
但是，这些四条腿到处跑的 “ 充电宝们 ”，可是 0 成本啊。把这些大家伙们利用起来，能调度出多少电呢？根据清华大学新能源动力系统课题组的测算，每辆车平均电量大于 65 千瓦时。那么 3 亿辆车的储能容量就能超过 200 亿千瓦时，基本就等于中国目前每天消费的电量。

M | 而截至 2022 年 10 月，中国的新能源车保有量已经达了 1149 万辆，大约能调度出接近 7.4 亿千瓦时的电来。所以，国家和车厂其实巴不得车主去挣他们的钱。在美国，日本、欧洲这些国家，很早就开始尝试这种模式了。2009 年的时候，美国就拨了 3000 万给福特，叫他们跟电网合作搞 V2G。

N | 不过，虽然福特整的不怎么样。可是，这帮车企里却跑出了个优等生，那就是特斯拉。
不得不承认，马斯克这个人，确实有点东西在身上的。在别人双向充电桩还没建利索的时候，他就开始布局下一步了。特斯拉早在 2012 年，就弄了个叫 Powerpack 的东西。而这个东西，就是我们前面说的储能站。
Powerpack 是专门提供给企业们储电用。之后，特斯拉又出了个容量更大的 Megapack，尝试面向政府储电。而现在，特斯拉更是直接把储能站，弄到别人家里去了。去年，特斯拉出了一个叫 Powerwall 的项目，专门针对家庭储能。这个家用的巨大号电池，会在用电低峰期的时候，自动地给自己充好电。

o | 到了用电高峰期的时候，它就能给家庭和电车反向输电了。
我们仔细琢磨一下，会发现这不就是虚拟电厂吗？基本上，Powerwall 储存的每度电，都可以赚到 2 美元的收益。有了这个玩意，车主们就可以做到躺着薅电网羊毛了。后来，欧洲、日本也都开始推广这种家用的小型储能站。在英国，有个小哥说自己靠这个一年赚了 900 英镑。他专门在电费 15 p/kwh 的时候充电，然后到了晚上用电高峰期的时候，再用溢价 31 p/kwh 的价格转卖给电网。并且，为了方便跟电网交易。

p | 特斯拉还做了支持线上能源货币交易的平台Autobidder，让每笔交易都更加清晰。
我国的 V2G 布局，虽然比欧美那边慢了点，但是其实也默默推行了很久。2019 年的时候，国家电网就和长城威马合作了一波。牵牵手，达成了一起搞 V2G 的战线。
甚至在北京市中再大厦示范区里，已经有人在用 V2G 挣钱了。6 个月的时间，九十多个车主们就挣到了 15025 块钱。

q |
但是俗话说的好，天下可没有免费的午餐。虽然这 V2G 计划看着是三方收益。在理想状态下，是可以做到你好，我好，他也好。但是，问题也就在这 “ 理想状态 ” 四个字。在这个完美计划里面，唯一受伤的就是 —— 我们的电动车。首先，我们要知道，电池的寿命是由充放电的循环次数决定的。

r | 电池只要完成了完整的充放，就一定会有寿命老化损失。
所以，我们频繁充放电来赚差价，其实就是拿电池的命在挣钱。电池很可能有命赚钱，没命花了。卖电赚的那几个子，没准还不够给自己换电池的。

s |
其次就是，如果双向充电桩和储能站要是没有大批量铺开，那 V2G 就没啥意思了。V2G 是个众人拾柴火焰高的项目，没有够多的众人参与，那火也烧不起来了。对于国家电网来说，如果参与进来的新能源车数量如果不够多。那在庞大的用电需求面前，V2G 基本上就是小打小闹。

t | 而对于咱们这些车主来说的话，这笔生意最大的诱人之处，就是能躺着把钱赚到手。但就算是现在，在很多二三线城市，普通的充电桩都没有建利索。甚至，还有 2000 个左右的乡镇，是完全没有任何充电设施的。那就更别说什么铺设全新的双向充电桩，或者是把储能站建到家里来。其实，对于咱们车主来说啊。V2G 这玩意，也就是偶尔用用，回点血。

u | 要真指望着它薅羊毛挣钱，肯定是不好使的。V2G 更大的意义，还是在于对国家电网的安全性提升上。只是，距离 V2G 真正派上用场的那天，可能我们还有很长的一段路要走。
