Abstract: Humanity has been reaping the benefits of flywheels for centuries: the sustained, steady rotation of potter's wheels has helped shape vases and jugs since antiquity; the first automobile created by Carl Benz in 1886 was started by turning a flywheel, and the electric motors in gyrobuses ran on electricity stored using flywheel technology.
Today, thanks to modern materials, frictionless bearings and long lifespans, flywheels are emerging as a serious contender in the energy storage market. Offering high capacity, extremely short response times, hundreds of thousands of charging cycles and years of reliable operation, they are even a viable alternative to lithium-ion batteries and other electro-chemical storage options.

Abstract: Anyone researching global hotspots for the production of green hydrogen would do well to have an atlas to hand-the list includes some exceptionally remote areas. On e of them is Inner Mongolia, a region in northern China featuring endless grassy plains, hundreds of rivers and lakes, and stretches of desert. In a recent study by the international Energy Agency (IEA), Inner Mongolia is marked in red on a world map of ideal locations for wind and solar power generations. In the foreseeable future-by 2030, to be precise-the IEA anticipates that it will be possible to produce clean power for less than USD 0,02 per kilowatt hour (kWh) there.

Abstract: Under normal circumstances, 2020 would have been an Olympic year. The summer games were scheduled by the Paralympic on 25 August. The eyes of the world were to be on Japan, with around two million visitors attending the games in person and many millions more watching on the screen. Japan's government had hoped that besides admiring the outstanding athletic performances, visitors would also be vowed by the country's transition to hydrogen in the post-Fukushima era.

Abstract: It is being called a "crucial resource for the success of the energy transition', the "energy carrier of the future', and even "the clean oil of tomorrow".One might be forgiven for thinking that he significance of hydrogen is one topic that everyone in the Federal Government agrees on, for a change. On 10 June, the "National Hydrogen Strategy " was unveiled by no less than four cabinet members who enthusiastically extolled the virtues of the technology-and of their own joint paper into the bargain.

Title: Use only horizontal ground distance [not grid distance] dimensions in land surveys

Subject: Use only horizontal ground distance [not grid distance] dimensions in land surveys
Keywords: Horizontal ground distance,dimensions, land surveys
Abstract: The anomaly of having two nearly identical units of linear measurement has led the USA to discontinue the use of the "US Survey Foot" after 1/1/2023, this then leaves the "International" foot as the only standard unit of linear measurement in the USA. However, the USA also has two nearly identical ways of stating dimensions in land surveys. Either Grid distances on their SPCS coordinate projection plane [usually at Sea Level] or Horizontal Ground Distance [where measured and used] are stated as dimensions. The continuation of this anomaly and duplexity prompts this paper.
Back in the 1970's, in New South Wales, Australia, the reverse situation arose. Then, the surveying profession proposed a similar to SPCS coordination system that required Projection [Grid] distance [instead of the established horizontal ground distance that everyone was using] as dimensions on survey and title plans. Also, so that the proposed grid distance dimension approximated horizontal ground distance, they required a 2o zone UTM projection [in addition to the established 6o UTM mapping projection]. This paper recounts the rationale used to ultimately reject the NSW proposal.
In Australia, all land dimensions are only horizontal ground distances, and all surveying and mapping coordinates are only on 6o UTM projection. Comparatively simple and unconfused, this Australian coordination practice has proven itself over the last 50 years and can claim to be the best survey coordination and mapping system in the world.

Abstract: Smartphones with dual-frequency multi-constellation GNSS (Global Navigation Satellite Systems) receivers are now available on the market. This study examines their usage in simple surveying tasks, such as data acquisition for GIS, e.g., for a tree cadastre, lantern cadastre,traffic signs, etc, as well as line documentation, such as for underground power lines. For the experiments, the Pixel 5 from the manufacturer Google LLC is chosen. Code and phase observations are recorded in different scenarios. Evaluation in post-processing based on these observations in Single Positioning (SPP) and precise Positioning (PPP) mode are carried out. In the analyses, the main focus is led on the achievable positioning accuracies and resulting deviations from reference points serving as ground truth. Apart from these parameters, other criteria, such as the measurement effort and costs, quality, accuracy and repeatability of the measurements are investigated. The results of the experiments indicate that he pixel 5, although it enables the recording of satellite data on two frequency bands, can only be used to a limited extent in practical surveying tasks because it does not meet the accuracy requirements on the centimeter level. The main reason for this is the quite low quality of the observations. With long observation times, however, results with a positioning accuracy of less than half a meter are achievable with the smartphone. Thus, the pixel 5 is capable to achieve the requirements in terms of positioning accuracy and reliability for applications such as data acquisition for Geographic Information Systems (GIS) and especially in Location-based Services (LBS).

Arobo-journalist has been writing for US daily The Washington Post since 2016.Its remit is limited to brief news stories rather than feature-length articles-for now. But Google's speech software, for instance, can make a hairdresser's appointment over the phone without the person on the other end of the line noticing anything out of the ordinary. As soon as the internet giant announced this breakthrough at a developers 'conference, a discussion flared up about whether machines should be required to declare themselves as such.

Abstract: The sump affecting Germany's wind market has had a devastating impact on production sites across the country. A case in point is Aurich. Ever since turbine manufacturer Enercon opened its doors there in 1984, fortune seemed to be smiling on the East Frisian district town. This year, however, local authorities will have to wave goodbye to 98 percent of their expected revenue-due in large measure to the introduction of auctions for wind decreed by the Federal Government last year.

Abstract: May be Peter Altmaier just wasn't able to make the switch from Berlin-mode to Brussels-mode. When it comes to the energy transition, Germany's economics minister likes to talk up the problems, and the cost of clean energy is an issue especially close to his heart. In Germany this has long earned him a reputation as an opponent of the transition. But on 11 June Altmaier was acting in an international capacity.

Abstract: new energy: Mr Sefcovic, You want to redesign the European energy market (see box) .At the same time, we are seeing developments such as Blockchain technology that are considered disruptive and have the potential to radically change the market. Do you worry that Blockchain could get in the way of your plans?
Maros Sefcovic: I don't think so. The technology is still relatively new. What I would say, I though, is that Blockchain is directly applicable to what we have in mind. I find it particularly interesting in terms of energy trading. When it comes to prosumers or trading between private citizens, Blockchain will be extremely helpful. The question is, how we make sure that every-thing runs smoothly, and that transmission lines are not overloded, for example?

Abstract: This study carried out a numerical modelling of storm surges for historical tropical cyclones that crossed the Chennai coat, the northern part of the coastline of Tamil Nadu, India. An extreme value analysis was made based on the peaks-over threshold 9POT) method to calculate extreme storm surge estimates for different return periods. The area's bathymetry was generated from the National Institute of Oceanography (NIO) sea-floor data derived from ETOP05(the earth's surface that integrates land topography and ocean bathymetry).Historical storm tracks in the vicinity of the study area were selected from the database. These storm tracks were used to generate temporally and spatially varying wind and pressure fields using the Holland method. Cyclones considered for the simulations are from a 35-year period, ranging from 1977 to 2012.Cyclones of significant intensity that occurred in the vicinity of Chennai were selected for modelling. The Delft 3D modelling software was used for the analysis .The domain considered for the study was generated on a rectilinear grid of size 540 x 670 km covering the coastline from Nagapattinam in Tamil Nadu to Diviseema in Andhra Pradesh with 1.35 km x 1.65 km as the size of each grid cell. The water level calculated by the Delft3D-FLOW module by solving the shallow water equations (SWEs) was extracted from the model over the entire domain at constant intervals and was monitored. The maximum surge in the water level at the Chennai coast was reported as the storm surge value for each cyclone. Results showed that Chennai is highly vulnerable to cyclones. A one-in-a-100-year cyclone can produce a storm surge of 1.0 m, which can pose severe hazards to the city, since the topography is very low. This study will assist officials in preparing for a disaster of this enormity.
