Tesla's 100MW/129MWh Powerpack venture in South Australia is accounted for to have made about $1 million AUD ($800,000 USD) in only a couple of days. The world's biggest battery arrangement of its kind went into operation toward the finish of 2017 and has been substantiating itself appropriate from the get-go.
The framework was worked to settle the vitality network of South Australia after it encountered real power outages amid extraordinary climate in 2016. Tesla won the agreement to manufacture the battery framework in conjunction with French vitality organization Neoen's adjacent breeze cultivate. As a component of the arrangement, Neoen approaches around 30 MW/90 MWh of the framework's ability to exchange on the open market while the rest is controlled by the South Australian government. Neoen is benefitting as much as possible from its offer of the operation this month as temperatures and vitality request take off.

Summer vitality request rising 

The framework can change from charging to releasing in not more than seconds, a component that enables Neoen to exploit vitality swings. As summer vitality request increments amid the exceptionally sweltering Australian summer, Tesla's battery was paid up to $1000/MWh to charge itself. The Australian Energy Review conceives that at that value it might have cleared up to $1 million over the most recent couple of days. The Review states: "Another perspective of this information is introduced beneath, demonstrating the real cost accomplished amid the purchasing (charging) and offering (age). It's difficult no doubt, yet it may have made around $1 million over the two days from the discount showcase."

Tesla to manufacture new plants

The framework is additionally working out for the legislature. A month ago it responded to the crash of a coal plant in just milliseconds, quicker than the vitality spectator could even monitor the progressions. Restore Economy's Giles Parkinson said that the framework is as yet being tried and that these great outcomes could simply be a glimpse of a larger problem of what it could truly be able to do. The accomplishment of the battery pack and wind farm is to such an extent that different states in Australia are quick to get their own rendition. Australian media announced as of late that Tesla had won the agreement to assemble a 20 MW battery framework to help the 204 MW twist cultivate at the Bulgana Green Power Hub.

China's Intercontinental Quantum Communication Network Is Now Online

China has finished its own quantum key system; a splendidly secure system for correspondence over the globe.

Review letter

Quantum cryptography will give unbreakable security to people, organizations, and governments. These frameworks can make unbreakable codes and give another level of secure interchanges. Guided by the laws of quantum mechanics, the laws that direct what occurs on a subatomic level, this innovation can't be undermined.

The Quantum Key Network 
The individual and touchy information that individuals share over the globe is scrambled, yet that encryption isn't as solid as you think. As encryption innovation develops so does the splitting innovation. China's quantum system could end this fight. The satellite system would superbly encode motions over extensive separations. Quantum keys are long series of numbers that can't be duplicated and are ensured by the points of confinement of PCs as well as by the laws of material science themselves.
The headpiece of the Chinese system is the record-breaking satellite Micius. A capable photon transfer and finder, Micius utilizes its fine lasers and identifiers to convey quantum data and get data at mind boggling speeds.
The satellite has achieved great accomplishments throughout the years. Just in 2017, the satellite sent two ensnared photons to ground stations that were 745 miles separated. A couple of months after the fact Micius transported a bundle of quantum data 870 miles from Tibet into space. After a progression of fruitful tests, Micius ended up being not just the ideal device for China's quantum key system yet additionally a noteworthy positive development for the universe of quantum cryptography.

250 Trains Will Be Fitted with Rooftop Solar Panels in India

India is well on its way to achieve its promised additional 160 GW of wind and solar energy by investing in floating PV panels and solar trains.

India is installing photovoltaic panels all over the country at breakneck speed. The country is investing in solar in a variety of ways, some common and others that are slightly out of the box. India surprised the world at the Climate Change Conference in 2015, by promising it would add 160 gigawatts (GW) of wind and solar by 2022 to the existing 26 GW.

Available space may be a problem

One problem the country faces is a lack of available land for its planned massive solar farms. Floating farms might be the answer. According to Indian news sources, two floating solar panel projects are soon to be developed in India. The first will be in the state of Andhra Pradesh, the second in the state of Kerala. Floating solar farms are a solar array system on a structure that floats on water. Generally, they are floating on a natural lake or human constructed reservoir.

Floating solar panel systems have the ability to be more efficient than land-based systems due to the cooling effect of the water. The new plants that are being carried out by the Arka Renewable Energy College will be the largest floating photovoltaic (PV) facilities in India.

India invests in solar panel trains

India is willing to invest in an unusual solar power project as it races towards its solar power goals. As well as floating solar panel farms, the country has also invested huge amounts of money and resources into adding solar panels onto the roof of trains.

Indian Railways will install flexible solar panels onto the roof of 250 local trains. The power generated from the panels will be used to power lights and fans on board. The new train is hoped to save approximately 21,000 liters of diesel a year, that would normally be used to power the interior.

The move is in a larger government push to modernize the Indian train system and make it much more environmentally friendly. Each new train is fitted with 16 solar panels on each carriage as well as battery back-ups. The trains are expected to offset carbon emissions by nine tonnes a year.

Suresh Prabhu, India's Union railway minister, told local media that this is a “path-breaking leap” towards the grander goal of making India’s trains more environmentally sound. The trains are only the first of many steps to green up the whole rail network system. Other green investments include using solar power for train stations. “7,000 railway stations across the country will be fed with solar power as per the Indian Railways mission to implement 1,000 megawatts of solar power capacity," Indian Finance Minister Arun Jaitley told guests, at a union budgetary speech in February this year.

The whole world will be watching India as it continues to rely increasingly on solar for its energy needs. It will also serve as a learning example for other countries eager to make the move to renewable energy.

A collaboration between researchers at UCL and Queen Mary University of London (QMUL) has led to the development of a new optical ultrasound needle that allows heart tissue to be imaged in real-time during keyhole procedures. The new technology gives doctors a high resolution image of soft heart tissue up to 2.5 cm in front of the needle when inside the body. The needle has been successfully tested on surgery on pigs and has the potential to make surgery safer and more accurate. Currently doctors have to rely on preoperative imaging scans and external ultrasound probes to give help them visualize the soft tissues being operated in during keyhole surgery as the surgery incision hole is too small to allow for imaging equipment as well. The breakthrough of combining the imaging technology with the surgical tools is a game changer.

High-frequency ultrasound imaging can provide exquisite visualizations of tissue to guide minimally invasive procedures. Here, we demonstrate that an all-optical ultrasound transducer, through which light guided by optical fibers is used to generate and receive ultrasound, is suitable for real-time invasive medical imaging in vivo. Broad-bandwidth ultrasound generation was achieved through the photoacoustic excitation of a multiwalled carbon nanotube-polydimethylsiloxane composite coating on the distal end of a 300-μm multi-mode optical fiber by a pulsed laser. The interrogation of a high-finesse Fabry–Pérot cavity on a single-mode optical fiber by a wavelength-tunable continuous-wave laser was applied for ultrasound reception. This transducer was integrated within a custom inner transseptal needle (diameter 1.08 mm; length 78 cm) that included a metallic septum to acoustically isolate the two optical fibers. The use of this needle within the beating heart of a pig provided unprecedented real-time views (50 Hz scan rate) of cardiac tissue (depth: 2.5 cm; axial resolution: 64 μm) and revealed the critical anatomical structures required to safely perform a transseptal crossing: the right and left atrial walls, the right atrial appendage, and the limbus fossae ovalis. This new paradigm will allow ultrasound imaging to be integrated into a broad range of minimally invasive devices in different clinical contexts.

DIY HEARTBEAT SENSOR

Heart rate💓💓 is the speed of the heartbeat measured by the number of contractions of the heart per minute (bpm).

When the heart beat detector is working, the beat LED flashes in synchronously with each heart beat. This digital output can be connected to micro-controller directly to measure the Beats Per Minute (BPM) rate.

It works on the principle of light modulation (Light to voltage converter) by blood flow through finger at each pulse.

Main Component it uses is Proximity Sensor.

This project demonstrates a technique to measure the heartbeat by sensing the change in blood volume in a finger artery while the heart is pumping blood . It consists of an infrared LED (Light emitting diode) that transmit an IR signal through the fingertip of the subject, a part of which is reflected by the blood cells.

The reflected signal is detected by photo diode sensor. The changing blood volume with Heart beat results in a train of pulses at the output of photo diode.

This type of sensors are already used commercially in mobile phones like Samsung Galaxy ALPHA, Galaxy S5 etc.
