7纳米可容纳多少电子通过_自充电纳米金刚石电池，可运行90年的电动汽车

Is this Cold Fusion deja vu all over again? Maybe. Or maybe not.

这是Cold Fusion似曾相识的故事吗？ 也许。 或者可能不是。

On my news aggregator yesterday was a story on newatlas.com titled, “Nano-diamond self-charging batteries could disrupt energy as we know it.” What the hell? That pegged out my weird-s**t-o-meter, so I had to read it.

昨天在我的新闻聚合器上， newatlas.com上有一个故事，标题为“纳米金刚石自充电电池可能会破坏我们所知道的能量。” 我勒个去？ 那把我的表怪异地固定了下来，所以我不得不读它。

First, here’s the backstory. It turns out that in 2016, back when [political rant deleted for space], a group of scientists at the University of Bristol took some radioactive waste graphite, squeezed it into teensy-weensy diamonds…and those diamonds generated a small amount of energy all by themselves, though not enough to power a cell phone. You see, in many reactors, graphite is used as a moderator to control the heat flow, and when the reactor is refueled or decommissioned, all the graphite removed is rich in carbon-14 and is highly radioactive, and at that time the United Kingdom had 95,000 tons of it sitting around pumping out zoomies (which is how we sometimes referred to radiation in the Navy), its half-life of 5730 years providing motivation for hundreds of generations of protesters.

首先，这是背景故事 。 事实证明，在2016年，[为了摆脱太空的政治喧嚣而删除]时，布里斯托大学的一群科学家拿走了一些放射性废石墨，将其压缩成小钻石，这些钻石全部产生了少量能量。靠自己，尽管不足以为手机供电。 您会看到，在许多React堆中，石墨被用作调节剂来控制热流，当对React堆进行加油或退役时，所有去除的石墨都富含碳14并具有高放射性，在当时是英国大约有95,000吨的水被抽出了变焦镜头 (这在海军中有时被称为辐射)，它的半衰期为5730年，为数百代抗议者提供了动力。

According to a 2017 article by the Snopes fact-checking service, the concept of transforming radioactive waste graphite into electricity-emitting diamonds has been around since at least 1973, and that it might be possible to safely encase the nano-diamond battery inside another diamond and and use the resultant “betavoltaic” diamond to generate electricity.

根据Snopes事实检查服务机构2017年的一篇文章 ，至少从1973年开始就存在将放射性废石墨转变为能发光的钻石的想法，并且有可能将纳米金刚石电池安全地包裹在另一颗钻石中并使用所得的“贝塔伏特”钻石发电。

So a company in California named NDB (for “Nano-Diamond Battery”, strangely enough) appears to have done just that. They claimed to have improved the process to the point where the radioactive nano-diamonds can generate enough electricity to be not just useful, but commercially viable and scalable. Here’s how the newer article explained the process:

因此，位于加利福尼亚的一家名为NDB的公司 (很奇怪地用“ Nano-Diamond Battery”来表示)似乎就是这样做的。 他们声称将Craft.io改进到了放射性纳米金刚石可以产生足够的电能的程度，不仅有用，而且在商业上可行且可扩展。 这是较新的文章解释该过程的方式：

This graphite is rich in the carbon-14 radioisotope, which undergoes beta decay into nitrogen, releasing an anti-neutrino and a beta decay electron in the process. NDB takes this graphite, purifies it and uses it to create tiny carbon-14 diamonds. The diamond structure acts as a semiconductor and heat sink, collecting the charge and transporting it out. Completely encasing the radioactive carbon-14 diamond is a layer of cheap, non-radioactive, lab-created carbon-12 diamond, which contains the energetic particles, prevents radiation leaks and acts as a super-hard protective and tamper-proof layer.

这种石墨富含碳14放射性同位素，该碳经历了β衰变成氮，在此过程中释放出抗中微子和β衰变电子。 NDB拿走这种石墨，将其纯化，然后用它来制造微小的碳14钻石。 菱形结构充当半导体和散热器，收集电荷并将其传输出去。 完全包裹放射性碳14钻石的是一层廉价的，非放射性的，实验室创建的碳12钻石，其中包含高能粒子，防止辐射泄漏并充当超硬保护和防篡改层。

Most of us would think that manufacturing a radioactive diamond and encasing it inside another manufactured diamond sounds outrageously expensive. Answers on Quora and Reddit indicate about $2300 per carat (’cause the internet never lies, right?), and one can’t help but wonder how much more it costs with radiation hazard mitigation measures. In an interview, the Chief Strategy Officer at NDB said that their manufacturing process is somewhat more expensive than for lithium-ion batteries, but the latter need to be charged, whereas NDB’s are not only self-charging, but:

我们大多数人都认为制造放射性钻石并将其封装在另一颗人造钻石中听起来过于昂贵。 Quora和Reddit上的答案表示每克拉约2300美元(“因为互联网永远不会说谎，对吗？)，人们不禁会想知道，采用辐射危害缓解措施需要花费多少钱。 NDB的首席战略官在接受采访时说，其制造过程比锂离子电池的制造过程要贵一些，但是后者需要充电，而NDB不仅是自充电的，而且：

“Think of it in an iPhone. With the same size battery, it would charge your battery from zero to full, five times an hour. Imagine that. Imagine a world where you wouldn’t have to charge your battery at all for the day. Now imagine for the week, for the month… How about for decades? That’s what we’re able to do with this technology.”

“在iPhone上考虑一下。 使用相同尺寸的电池，它将以零到一小时的电量充满电，一次充电五次。 设想。 想象一下一个世界，您一天无需为电池充电。 现在想象一周，一个月……几十年了？ 这就是我们能够使用这项技术的能力。”

He claims the technology is scalable enough to power electric cars where the batteries may have a useful life of up to 90 years. Let that sink in for a moment: a self-charging battery that can power your car for 90 years, for not much more than what current electric-vehicle batteries cost today. The company claims it can even be used to power aircraft.

他声称，这项技术具有足够的可扩展性，可以为电动汽车提供动力，其中电池的使用寿命可达90年。 让它暂时消失：一种可以为您的汽车供电90年的自充电式电池，价格不超过目前的电动汽车电池价格。 该公司声称它甚至可以用来驱动飞机。

Damn.

该死的。

I hate being a cynic. Read most of my articles — hope and optimism drips off them like honey poured over…well, let’s not go there. But even an eternal Pollyanna like me must acknowledge the fact that if it sounds too good to be true, it probably is. After all, I’m old enough to remember the cold fusion fiasco of 1989 where two scientists named Pons and Fleischmann had claimed to produce fusion — that holy grail of energy production — at room temperature. The hype and hope were insane, and energy would be cheap and plentiful for all…until it all went up in smoke like so much phlogiston, and the two scientists’ names became synonymous with the danger of not adhering to strict standards of scientific rigor. The collective dreams of geekdom were dashed upon the baryonic rocks of the scientific method. Yes, even today there’s highly-qualified scientists striving to make cold fusion work, but more and more it’s looking like a high-tech version of a perpetual motion machine.

我讨厌成为一个愤世嫉俗的人。 阅读我的大多数文章-希望和乐观情绪像蜂蜜一样倒在它们身上……好吧，我们不要去那里。 但是，即使像我这样永恒的Pollyanna也必须承认一个事实，那就是，如果听起来听起来太好了而无法实现，那可能就是事实。 毕竟，我年纪大了，可以回想起1989年的冷核聚变惨案 ，当时两名名叫Pons和Fleischmann的科学家声称在室温下产生聚变-这是能源生产的圣杯。 炒作和希望是疯狂的，能源对所有人来说都是便宜而充足的……直到所有这些都像火药一样烟消云散，而两位科学家的名字成了不遵守严格科学严格标准的危险的代名词。 怪异的集体梦想在科学方法的重压岩石上破灭了。 是的，即使在今天，也有高素质的科学家努力使冷聚变工作，但是越来越多的科学家看起来像是永动机的高科技版本。

As far as NDB goes, it seems the jury is still out. Just because a scientific concept seems possible, that doesn’t mean the engineering on a mass-production scale is feasible, much less commercially viable. According to Germany-based finanzen.net:

就新开发银行而言，陪审团似乎还没有成立。 仅仅因为科学概念似乎可行，并不意味着大规模生产的工程是可行的，而在商业上则不可行。 根据德国的finanzen.net的数据 ：

NDB…today announced completion of two successful Proofs of Concept tests of the NDB battery at Lawrence Livermore National Laboratory and the Cavendish Laboratory at Cambridge University. NDB’s battery achieved a breakthrough 40% charge, a significant improvement over commercial diamonds, which have only 15% charge collection efficiency. NDB also announced its first two beta customers, including a leader in nuclear fuel cycle products and services and a leading global aerospace, defense and security manufacturing company. Development of the first NDB commercial prototype battery is currently underway and will be available later this year.

NDB…今天宣布在劳伦斯·利弗莫尔国家实验室和剑桥大学的卡文迪许实验室成功完成了两项关于NDB电池的概念验证测试。 NDB的电池实现了突破性的40％充电，比仅具有15％电荷收集效率的商用钻石有了显着改进。 NDB还宣布了其首批两个beta客户，其中包括核燃料循环产品和服务的领导者以及全球领先的航空，国防和安全制造公司。 目前，第一款NDB商业原型电池的开发正在进行中，并将于今年晚些时候上市。

So it’s definitely a maybe. We may have seen this movie before, and if so, it doesn’t end well. But if this technology pans out, we could have safe, relatively-green, radioactive-waste-mitigating, and self-recharging batteries that we can pass down to our kids and grandkids, and for not much more than we’re paying for lithium-ion batteries today.

所以绝对是一个可能。 我们可能以前看过这部电影，如果这样的话，收尾不好。 但是，如果这项技术得以推广，我们就可以拥有安全，相对绿色，减轻放射性废物和自我充电的电池，并将其传递给我们的孩子和孙子孙女，而且价格不超过我们为锂支付的费用今天的负离子电池。

I mean, Damn.

我的意思是， 该死
