Bikes are generally used for transportation, enjoyment, and sport. With electric bikes, you can enjoy riding a bike with an integrated motor to enhance your riding experience. These e-bikes can run at high speeds and cover long distances. However, for safety purposes, e-bikes are restricted to going beyond 20 mph or 25 mph, depending on your country’s speed limit.

Cardiff, UK-based inventor Grant Sinclair has designed the IRIS eTrike electric bike that looks unique and futuristic. The inventor claims that the IRIS eTrike e-bike is the fastest street-legal Electrically Assisted Pedal Cycle (EAPC) bike in the world.

The IRIS eTrike measures 260 cm long, 94 cm wide, and 128 cm high, and the bike’s weight, including the battery, is 50 kg. The bike has a unique three-wheel design with 24-inch carbon BMX wheels at the front and 26-inch carbon MTB wheels at the rear.

This bike comes with three power choices of 250-watt (80 Nm), 500-watt (100 Nm), and 750/1000-watt (160 Nm) Bafang mid-drive motors, which provide maximum bike speeds of over 30 mph (48 km/h). The bike is packed with a 48 v (20 Ah) portable lithium-ion battery that offers a range of up to 30 miles (48 km) from a single battery charge.

This e-bike features extra safety, weather protection, easy to use go-kart-like handling. The cabin includes a universal smartphone dock for GPS, music playback and calorie counting, etc. It also has a built-in 120° rear-view camera that streams real-time video to the rider’s mobile devices. A powerful cooling system is also included with an anti-pollution High-Efficiency Particulate Air (HEPA) air purifier to combat smoke, germs, and viruses.

The chromoly steel trike chassis with ultra-light foam EPP body structure is inspired by ski helmet technology. The body design ensures additional rider safety, and the futuristic design of the e-bike is inspired by the aerodynamic helmets used for velodrome bike racing.

The IRIS eTrike is available on their official website for a special-pre-order price of $6,222.55. It has an estimated worldwide delivery of Q1 2024 for new pre-orders.

Clean energy generates the energy we need without any adverse environmental effects. Renewable energy, such as wind power, hydropower, biofuel, and solar, provides affordable, reliable energy and various economic benefits.

Similarly, the piezoelectric effect converts mechanical energy into electric energy or inversely. However, traditional piezoelectric materials used in commercial devices had limited capacity for generating electricity. Also, they generally use lead, which harms human health and the environment.

To overcome this problem, researchers at the University of Waterloo and the University of Toronto have developed a new piezoelectric material that is compact, reliable, low-cost, and eco-friendly.

“Our breakthrough will have a significant social and economic impact by reducing our reliance on non-renewable power sources,” said Asif Khan, a Waterloo researcher, and co-author of a new study on the project. “We need these energy-generating materials more critically at this moment than at any other time in history.”

Using the Jahn-Teller effect, researchers made a large crystal of molecular metal-halide compound called EDABCO-copper chloride (CuCl4). It is a well-known chemistry concept related to the spontaneous geometrical distortion of a crystal field. EDABCO-CuCl4 has one of the most significant energy density potentials of any recorded material, and the resulting piezoelectric energy harvesters are highly stable.

Then this material is used to create nanogenerators with a record power density that can generate tiny mechanical vibrations under any dynamic condition, from human motion to automotive vehicles. In this process, it does not require lead or non-renewable energy.

This nanogenerator is 2.5 sq. cm. in length and about the thickness of a business card. It can be easily used in many situations and has the potential to power sensors in all kinds of electronic devices, including the billions needed for the Internet of Things.

In the future, integrating nanogenerators with various devices could help generate power from vibrations of the device and will be helpful in different circumstances.

According to Dr. Dayan Ban, a researcher at the Waterloo Institute for Nanotechnology, in the future, an aircraft’s vibrations could power its sensory monitoring systems, or a person’s heartbeat could keep their battery-free pacemaker running.

Electric bikes are increasing in markets vastly. The e-bikes are futuristic, and they have many advantages over cars, such as moving door-to-door efficiently, spending less time in traffic jams, and increasing health benefits.

Targeting to reduce the number of cars on the street in favor of a mix of electric and human-powered mobility vehicles- Portland, Oregon-based Vvolt company has unveiled their series of e-bikes named Slice Lite, PIE, and Slice DLX.

All three bikes are different from each other’s and targeted for different goals.

Slice Lite is an e-bike for lite work, such as riding around and bringing groceries from markets. It is powered by a rear hub 350W motor and 500 Wh battery, providing this e-bike with a maximum speed of 20 mph (32 km/h) and a maximum range of up to 55 miles (88.5 km). This bike weighs only 60 lbs (27 kg) and carries maximum 300 lbs (136 kg) weight.

PIE is a Fun, reliable, and massively capable bike made for replacing a need for a family car. It is powered by a mid-drive 500W motor and more than 1000 Wh battery, giving this bike a maximum range of 80 miles (128 km) and 28 mph (45 km/h) speed. Even with this massive battery, this bike weighs only 80 lbs (36 kg) and can carry a maximum weight of up to 440 lbs (199 kg).

Slice DLX is very similar to the PIE in a compact package. The same motor hub powers it and has the same speed and range as PIE. The bike has a more than 600 Wh battery. This bike weighs 65 lbs (30 kg) and carries maximum 300 lbs (136 kg) weight.

PIE and Slice DLX both the bikes have more advanced features, such as a boost button, smart module with GPS, and LTE connectivity that pairs with the Vvolt Rider app, enabling a range of features.

The Slice Lite is integrated with a hydraulic disc of 2 pistons, and the PIE and Slice DLX got a hydraulic disc of 4 pistons.

All three bikes have the same wheel size of 24 inches rear and 20 inches front, that are 3 inches puncture-resistant tires. Also, these bikes are integrated with torque, cadence, and speed sensors. The e-bikes are available for a rider’s height of 4 feet 9 inches to 6 feet 4 inches.

Vvolt’s e-bikes Slice Lite and Slice DLX are available at starting price of $2,049 for Lite and $3,999 for DLX. You can pre-order PIE for $200, available from late 2023.

22/05/2023

Recent advances in prosthesis development for upper-limb amputees have shown that it is possible to restore touch sensation using different approaches. However, current technologies do not allow the restoration of thermal sensation.

To provide upper-limb amputees with a more natural feeling, researchers from Switzerland’s Ecole Polytechnique Fédérale de Lausanne (EPFL) have developed a new bionic technology that allows amputees to sense the temperature of objects – both hot and cold – directly in the phantom hand. The technology opens up new avenues for non-invasive prosthetics.

“Temperature feedback is essential for relaying information that goes beyond touch; it leads to feelings of affection. We are social beings, and warmth is an important part of that,” says Micera, Bertarelli Foundation Chair in Translational Neuroengineering, professor at EPFL and SSSA who also co-led the study. “For the first time, after many years of research in my laboratory showing that touch and position information can be successfully delivered, we envisage the possibility of restoring all of the rich sensations that one’s natural hand can provide.”

For their study, researchers created a non-invasive device called MiniTouch, which provides thermal feedback about the object being touched and is specifically built for integration into wearable devices like prosthetics.

The MiniTouch consists of a thin, wearable sensor that can be placed over an amputee’s prosthetic finger. The finger sensor detects thermal information about the object being touched, more specifically, the object’s heat conductivity. If the object is metallic, it will naturally conduct more heat or cold than, for instance, a plastic one.

A thermal electrode, also known as thermodes, is placed in contact with the skin on the amputee’s residual arm. It heats up or cools down, relaying the temperature profile of the object being touched by the finger sensor.

Researchers recruited more than 25 volunteers in less than two years for the trials. The technology was successfully tested in 17 out of 27 patients.

“Of particular importance is that phantom thermal sensations are perceived by the patient as similar to the thermal sensations experienced by their intact hand,” explains Shokur, EPFL senior scientist neuroengineer who co-led the study.

The technology could be integrated into wearable devices, such as prosthetics, in the future to provide a more realistic touch to amputees.

With the rapidly increasing demand for energy storage, the lithium-ion battery market continues to expand. However, the traditional battery electrode manufacturing method involves toxic organic solvents and energy-consuming drying/recovering processes. The evaporation of the solvent leads to uneven materials distribution, and the electrodes’ microstructure could impede the fast-charging ability.

Researchers at Worcester Polytechnic Institute (WPI) have developed a solvent-free process to manufacture lithium-ion battery electrodes that are greener, cheaper, and charge faster than electrodes currently on the market. The advance could improve the manufacturing of batteries for electric vehicles.

The new dry-print manufacturing process avoids the toxic solvents and the long drying times needed when manufacturing electrodes with slurries and conventional production methods. Lead researcher Yan Wang said the new process could be scaled up and reduce electrode manufacturing costs by up to 15% while also producing electrodes that can charge faster than conventionally produced electrodes.

“Current lithium-ion batteries charge too slowly, and manufacturers typically use flammable, toxic, and expensive solvents that increase the time and cost of production,” Wang said. “Our solvent-free manufacturing process addresses those disadvantages by producing electrodes that charge to 78% of capacity in 20 minutes, all without the need for solvents, slurries, and long production times.”

Lithium-ion battery electrodes are typically made by mixing active materials, conductive additives, polymers, and organic solvents to create a slurry. That slurry is pasted onto a metal substrate, dried in an oven, and cut into pieces for use in batteries. The solvents are recovered through distillation.

In contrast, the new process involved mixing together dry powders that were electrically charged so they would adhere when sprayed onto a metal substrate. The dry-coated electrodes were then heated and compressed with rollers. The researchers reported skipping the conventional drying and solvent-recovery process cut battery manufacturing energy use by an estimated 47%.

The unique microstructure could also benefit the electrode with better fast-charging ability and longer cycle life. Thus, the team believes this work paves a more efficient and economical way for battery manufacturing with higher-quality electrode products.

Dry electrode technology can be cost-effective as it eliminates the need for solvent and solvent recovery steps and increases energy density. The technology also has the potential to reduce production costs by simplifying the manufacturing process and lowering the facility space requirement. Researchers say these solvent-free manufacturing processes are also compatible with next-generation batteries, especially the solid-state battery (SSB), and have already attracted the focus of the industry.

21/05/2023

Renowned carmaker BMW and German boat builder TYDE have unveiled THE ICON, a flagbearer for sustainable high-end mobility on water, at the 76th Cannes film festival. THE ICON is the first battery-powered watercraft of its kind and brings together emission-free travel with a top-to-bottom vision of luxury.

The innovative project is the result of an in-depth sharing of knowledge between experts at BMW, TYDE, and Designworks, a BMW Group subsidiary with studios in Los Angeles, Munich, and Shanghai. The construction of the concept was entrusted to boat maker TYDE while the powerful electric drive system draws from high-voltage batteries supplied by BMW i. The luxury seafaring experience is accompanied by an exclusive soundtrack composed by award-winning film composer and frequent BMW collaborator Hans Zimmer.

At 13.15 meters in length and with a top speed of 30 knots (55 km/h), THE ICON is a trailblazer for a new breed of battery-electric watercraft. The new watercraft uses a battery-electric drive system to set new standards in its sector.

Until now, marine electric mobility has been restricted to smaller, slower craft with comparatively little range, and the segment for faster boats with larger ranges is dominated by models with combustion engines. THE ICON redefines this relationship between the dimensions, top speed, and range of an electrically powered watercraft.

This is made possible by an innovation from yacht racing – hydrofoils. This advanced hull form reduces the energy requirement by up to 80% compared with a conventional design. The foiling technology also provides a higher level of traveling comfort and higher speeds.

A pair of 100 kW electric motors convert 240 kWh of energy supplied by six batteries from BMW i for a range of more than 50 nautical miles (92.6 km) and a cruising speed of 24 knots (44 km/h). In combination with its innovative drive system and foiling technology, the electric vessel navigates the seas silently, smoothly, and cleanly.

The vessel features a flat hull with a lightweight, origami-like superstructure, enabling a particularly smooth traveling experience. With its prism-like transparent architecture, the basic outline enables a width of 14.7 feet in the rear section, allowing for a spacious lounge entrance. In addition, passengers can enjoy the view directly into the water through large glass surfaces, accentuated by iconic LED light strips at the bow, stern, and charging connection points throughout the vessel.

THE ICON’s angled glass doors open to a lounge area with artistically designed furniture on a luxurious carpet that creates a kaleidoscope effect. The yacht also sports 360-degree rotating seats, an easy-to-reach tablet-based infotainment system, and a 32-inch touchscreen display with 6k resolution, with a look and feel that resembles the BMW iDrive control/operation system.

In addition, passengers looking for a different audio experience can turn to the onboard Dolby Atmos system, which delivers superb sound quality throughout the vessel. Voice commands can be used to access key functions such as range information and weather reports.

THE ICON impresses with a powerful drive system that creates neither noise nor emissions. Foiling technology allows it to reach high speeds without generating waves or dragging out a wake behind it. Indeed, the only things THE ICON leaves behind during every journey are pleasure and joy.

In August 2021, at the Tesla AI Day, Elon Musk revealed that the company is working on its own AI-driven humanoid robot called Tesla Bot. Almost a year later, at the Cyber Rodeo event in Texas, Musk discussed the robot again, referring to it as the Optimus Sub-Prime and emphasizing the high priority he had assigned to the project, and stating that the robot would be ready for production by 2023.

Now in 2023, the Tesla Bot is not quite production-ready, but recent updates indicate significant progress. Tesla is showing off new footage of the robot where it is walking with its installed chassis and successfully performing increasingly complex daily tasks without any assistance. The new video was presented by Elon Musk, during Tesla’s 2023 shareholders meeting event, with Musk claiming the team just put it together the night before.

The initial version could barely walk forward and perform any manual labor on stage alone. The company is showing that the robots can now walk forward with improved stability compared to their initial reveal, although at a slow pace.

The video highlights some specific updates to the Tesla Bot project, including motor torque control, environment discovery and memorization, AI training from human-tracked movements, and improved object manipulation. It also demonstrates the bots’ new capabilities of picking up items and identifying objects.

In addition, the video featured a demonstration where a Tesla Bot successfully picked up objects from one container and put them in a second container, illustrating the AI training process derived from human demonstrations.

20/05/2023

Dufour Aerospace, a Swiss aviation company that developed aerobatic aircraft, announced that it was selected by Innosuisse, the innovation agency of the Swiss Confederation, for a grant. The grant was made pursuant to a 2022 call for projects under the Swiss accelerator program of Innosuisse. Fifty-two companies will receive funding, along with Dufour. The company will receive almost $3 million (CHF 2.5 million), the maximum grant available under the program.

Dufour Aerospace applied for funding to develop Dufour’s next-generation prototype of Aero2, a key step towards demonstrating the full capabilities of the commercial version of Aero2.

The first product Dufour Aerospace will launch is the Aero2, an unmanned aerial vehicle specifically designed for the transportation of critical cargo, such as medical supplies of up to 40 kilograms (88 lbs), in medium to long-range distances. Its tilt-wing design combines the best of the helicopter and airplane worlds: vertical take-off and landing on even the smallest spots and energy-efficient long-range flight at high speeds.

With its hybrid module, Aero2 offers flight time and endurance that is out of reach for today’s electric-only VTOL applications. Its payload capacity makes it an excellent fit for search and rescue (SAR) operations, long-endurance terrain and infrastructure surveillance, and transporting cargo to remote and urban areas. Its hybrid-electric powertrain promises a flight time of up to three hours or nearly 250 miles (400 km) in standard configuration (40 kg) and up to 12 hours with reduced payload.

The Aero2 has a cruise speed of up to 170 km/h (92 knots). The Aero2 will enter commercial service in 2025.

The manned Aero3, featuring a spacious cabin with eight seats and large doors, is the next aircraft in development by Dufour Aerospace.

“Dufour Aerospace is a pioneering eVTOL company, and we are pleased Innosuisse recognized our efforts to create globally leading technology in Switzerland,” said Thomas Pfammatter, co-founder and chief executive officer of Dufour Aerospace. “The grant will be used to continue our development of prototypes of the innovative Aero2 unmanned tilt-wing drone. Our team is thankful to Innosuisse for this vote of confidence in our work.”

The latest grant follows several significant milestone achievements by Dufour Aerospace. In January, the company closed a Series B financing round led by Vista Global. In late 2022, Dufour announced the largest civilian drone purchase in U.S. history, made with Spright, the drone division of Air Methods. Meanwhile, prototype development, flight testing, and software development continue a pace in Switzerland.

20/05/2023

NASA’s TeraByte InfraRed Delivery (TBIRD) system has set a new record for the fastest data transfer rate ever performed in space. The golden, tissue box-sized satellite demonstrated a 200 gigabit per second (Gbps) space-to-ground optical link speed between a satellite in orbit and Earth, the highest data rate ever achieved by optical communications technology.

These data rates are made possible by using laser communications, which packs information into the oscillations of light waves in lasers.

Launched in May 2022, TBIRD was carried into orbit by NASA’s Pathfinder Technology Demonstrator 3 (PTD-3) satellite. This data communication link surpasses the previous 100 Gbps milestone previously demonstrated by the same team in June 2022. With this speedy connection, TBIRD can send down multiple terabytes of test data to Earth during a single six-minute pass over a ground station.

NASA currently relies on radio waves to transmit data to and from its orbiting spacecraft with similar methods to how radio broadcasts are sent to a car radio or how a cell phone communicates with a cell tower. More efficient communications are essential for smooth mission operations and effective science as the space agency looks to send humans to the Moon and beyond.

The ultra-high-speed capabilities of laser communications, also known as optical communications, will make it possible to pack more data into each transmission from space. CubeSats like PTD-3 are ideal spacecraft for testing communications technologies due to their cost-effectiveness and small size. PTD-3 is only about the size of two stacked cereal boxes. The TBIRD payload it carries is no larger than the average tissue box.

Built and operated by Terran Orbital of Irvine, California, for NASA, PTD-3 was launched into orbit on SpaceX’s Transporter-5 rideshare mission from NASA’s Kennedy Space Center in Florida and synchronized with Earth’s orbit around the Sun in such a way that the small satellite entered a “fixed” position relative to the Sun. This means PTD-3 is able to pass over the ground station on Earth at the same time twice each day, so TBIRD can test this space-to-ground communications link.

“Achieving 100 Gbps in June was groundbreaking, and now we’ve doubled that data rate – this capability will change the way we communicate in space,” said Beth Keer, the mission manager for TBIRD at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Just imagine the power of space science instruments when they can be designed to fully take advantage of the advancements in detector speeds and sensitivities, furthering what artificial intelligence can do with huge amounts of data. Laser communications are the missing link that will enable the scientific discoveries of the future.”

With TBIRD’s successful demonstration of laser communications as a practical tool for transferring data from space to ground, future NASA missions can integrate this technology into their designs.

19/05/2023

Canada’s Sanctuary AI, which aims to create the world’s-first human-like intelligence in general-purpose robots, has now announced a major step forward with the unveiling of its sixth-generation general-purpose robot named Phoenix.

Phoenix is, the company says, the world’s first humanoid general-purpose robot powered by Carbon, its pioneering AI control system. The system is designed to give Phoenix human-like intelligence and enable it to do a wide range of work to help address the labor challenges affecting many organizations today.

Sanctuary has demonstrated Phoenix for hundreds of different tasks identified by customers from more than a dozen different industries.

The Phoenix model is the sixth generation of the platform and is the first robot model to be complete with legs and worthy of being characterized as a humanoid bipedal robotic system.

Standing at 5′ 7″ and weighing 155 lbs (70 kg), the humanoid robot is just about the size of an average human. It can carry a payload of up to 55 lb (25 kg) and has a maximum speed of 3 miles per hour (4.8 km/h). The Phoenix hand design features 20 degrees of freedom, which the company says rivals human hand dexterity and fine manipulation with proprietary haptic technology that mimics the sense of touch.

“We designed Phoenix to be the most sensor-rich and physically capable humanoid ever built and to enable Carbon’s rapidly growing intelligence to perform the broadest set of work tasks possible,” said Geordie Rose, co-founder and CEO of Sanctuary AI. “We see a future where general-purpose robots are as ubiquitous as cars, helping people to do work that needs doing, in cases where there simply aren’t enough people to do that work.”

Its literal take on “general purpose” and emphasis on creating a technology that can conduct physical work just like a person sets Sanctuary AI apart from others in the industry. “To be general-purpose, a robot needs to be able to do nearly any work task, the way you’d expect a person to, in the environment where the work is,” said Rose. “While it is easy to get fixated on the physical aspects of a robot, our view is that a robot is just a tool for the real star of the show, which in our case is our proprietary AI control system, the robot’s Carbon-based mind.”

19/05/2023

Phase change materials store thermal energy in the form of latent heat and are often integrated with high thermal conductivity metals to make composites that have both high power density and large energy storage capacity.

A team of researchers from Texas A&M University has established foundational design principles for composite phase change materials to store thermal energy rapidly. This breakthrough is expected to dramatically simplify the design process, allowing a near-optimal composite phase change material to be simply calculated without exhaustive computational fluid dynamic calculations or extensive iterative design.

Previously, several studies have investigated the performance of thermal energy storage systems. However, none have yet revealed insights into improving rate performance, optimization, and prediction of performance until now.

The new research has addressed a fundamental question of how to design a composite phase change material that balances both energy density (how much energy can be stored) and power density (how quickly energy can be stored) without adding excess mass or volume.

Funded by the Office of Naval Research, this research provides a theoretical framework to design and optimize cylindrical composites with three figures of merit – minimization of temperature rise, maximization of the effective volumetric heat capacity, and maximization of the effective heat capacity based on mass.

The figures of merit developed in this research can assess the performance of most composite phase change material systems and help design future cylindrical composites while accounting for the thermal loads specific to the thermal storage application.

In addition, the team experimentally demonstrated that treating the system as an effective composite allowed them to quickly simplify the calculations and predict near-optimal structures.
