法国100万辆电动汽车充电点里程碑法国配电系统运营商Eenedis报告说，今年第二季度有100万个公共和私人电动汽车充电点连接到该国的配电网络，自2021年开始以来增加了一倍以上。
大多数是私人的，略多于一半在私人住宅，其余在公司，只有大约6%在公共场所。虽然全国各地的分布是不均匀的，但按每10万居民计算，有更大的同质性，东南地区的装备尤其好。
目前，法国的道路上有超过90万辆电动车和插电式混合动力车，Enedis的研究表明，大多数电动车用户(近90%)主要在家里充电。
预计到2035年，电动汽车的数量将增长到1700万辆。重点关注的部分是公寓，约有18万套公寓和一个停车场，代表约690万个停车位，但其中只有2%配备了充电基础设施。
英国的集中式24小时供应商转换新的集中式转换服务承诺提供24小时的供应商转换，现已在英国上线。
长期以来，供应商转换一直是一个问题，许多人认为这个过程太复杂、太慢--往往需要三周时间--而且经常出错。
新服务由负责建设中央智能电表数据网络的数据通信公司开发，作为附加服务，说明这种连接客户与供应商、网络运营商和其他部门第三方的中央网络和存储库如何能够提供附加价值。
新服务的目的是最初将转换能源供应商的时间减少到5个工作日，后来减少到下一个工作日。它还应该减少由于地址数据质量差而导致的开关失败或不应该执行的数量。
氢气推动的太空热气球乘坐号称世界上唯一的碳中和宇宙飞船到太空边缘进行6小时的新颖飞行，现在已经开始预订。
海王星号飞船将于2024年底发射，它由一个充满绿色氢气的气球组成，气球下面悬挂着一个球形的太空舱，里面有一个飞行员和8名乘客的座位和设施，并提供一个全景视角。
建议该飞行器将从佛罗里达州中部的肯尼迪航天中心发射，以每小时约20公里的速度上升到约30,500米的高度--高于地球大气层的大部分--在那里将飞行约两小时，然后进行同样时间的下降，在海洋中的一个指定地点溅落，供人领取。
这个概念是由 "豪华太空旅行公司 "Space Perspective提出的。费用为12.5万美元，可通过信用卡或加密货币支付1000美元的可退还押金来确保座位--但根据该公司的网站，首批航班已经售罄。
用可穿戴设备采集能量能量收集是一个蓬勃发展的兴趣话题，它有可能从许多不同的来源为低能量设备产生至少少量的电力。
现在，华盛顿大学的研究人员已经创造了他们所称的第一种灵活的、可穿戴的热电设备，该设备也是柔软的、可拉伸的，但很结实，可将人体热量转化为电能。
这些新设备是以3D打印复合材料的形式创建的，其中含有液态金属合金的填充材料，并已被证明可在可拉伸的纺织面料和曲面上打印，这表明它们有可能应用于服装或臂章等物品。
"华盛顿大学纳米工程系统研究所助理教授Mohammad Malakooti说："我们研究的一个独特方面是，它涵盖了整个光谱，从材料合成到设备制造和表征的全部过程。
据记录，与之前的可拉伸热电发电机相比，该设备的功率密度增加了6.5倍，并且在30%的应变下经过15000次以上的拉伸循环后仍保持完全的功能。

Technology Trending: EV Charge Points, Supplier Switching, Energy Harvesting, Hydrogen Powered Spaceflight1 million EV charge point milestone in France
French distribution system operator Enedis has reported the passing of 1 million public and private electric vehicle charging points connected to the country’s distribution network in Q2 of the year – a more than doubling since the start of 2021.
The majority are private, slightly more than half in private homes and the balance at companies, with only about 6% in public locations. And although the distribution across the country is uneven, on a per 100,000 inhabitant basis there is greater homogeneity, with the southeast particularly well equipped.
More than 900,000 electric and plug-in hybrid vehicles are on France’s roads currently and Enedis’s studies have indicated that the majority of EV users, almost 90%, do their main charging at home.
The number of EVs is estimated to grow to 17 million by 2035. A segment for focus is the condominiums, with around 180,000 with more than ten apartments and a parking lot and representing around 6.9 million parking spaces, but just 2% of them are equipped with charging infrastructure.
Centralised 24-hour supplier switching in GB
The new centralised switching service promising to deliver a 24-hour supplier switching is now live in Great Britain.
Supplier switching has long been an issue there, with the process found by many to be too complicated and too slow – often taking up to three weeks – and often going wrong.
The new service has been developed by the Data Communications Company, responsible for building the central smart meter data network, as an add-on and illustrates how a central network and repository of this type connecting customers with suppliers, network operators and other sector third parties can deliver added value.
The new service is aimed to initially reduce the time it takes to switch energy supplier to five working days and, later, to the next working day. It also should reduce the number of switches that either fail or should not have been executed as a result of poor quality address data.
Hydrogen propelled space ballooning
Booking is now open for a novel 6-hour flight to the edge of space in what is billed as the world’s only carbon neutral spaceship.
Spaceship Neptune, set for launch in late 2024, is comprised of a balloon filled with green hydrogen, below which is suspended a spherical capsule with seating and facilities for a pilot and eight passengers and providing a panoramic perspective.
The proposal is the craft will launch from the Kennedy Space Centre in central Florida and at a speed of about 20km/h will make a two-hour ascent to an altitude of about 30,500m – above the majority of the Earth’s atmosphere – where it will fly for about two-hours before making a similarly timed descent to splash down at a designated location in the ocean for pickup.
The concept is from the “luxury space travel company” Space Perspective. And the cost is $125,000, with seats securable with a $1,000 refundable deposit payable by credit card or cryptocurrency – but the first flights are already sold out, according to the company’s website.
Energy harvesting with a wearable
Energy harvesting is a burgeoning topic of interest with its potential to generate at least small amounts of power for low energy devices from many different sources.
Now University of Washington researchers have created what they claim as a first-of-its kind flexible, wearable thermoelectric device that also is soft and stretchable but sturdy that converts body heat to electricity.
The new devices were created as 3D printed composites with a filler material containing liquid metal alloys and have been shown to be printable on stretchable textile fabrics and curved surfaces, indicating their potential application to clothing or objects such as armbands.
“One unique aspect of our research is that it covers the whole spectrum, all the way from material synthesis to device fabrication and characterisation,” said Mohammad Malakooti, assistant professor in the University of Washington’s Institute for Nano-Engineered Systems.
The device is recorded as showing a 6.5 times increase in power density compared to previous stretchable thermoelectric generators and to remain fully functional after more than 15,000 stretching cycles at 30% strain.
