Urtopia’s carbon fiber e-bicycle goes weighty on the tech

The electrification of the bicycle has historically meant just that: A bike, but with an electric motor. You might discover some other clever conveniences on greater-close types, but “a lot less is a lot more” has typically been the way. Urtopia, the most current e-bike manufacturer from China, has other thoughts. Its debut ride is, on paper, a single of the most tech-major bikes we’ve seen. The spec sheet reads far more like a phone’s than a following-gen fixie.

For instance, beyond the 250W hub motor with 3 ranges of using guide (and an estimated 30-80 mile array), there is an integrated dot-matrix display, a fingerprint reader, GPS, 4G (by means of eSIM), mmWave sensors for car detection, an integrated alarm and, well… the record goes on.

The bicycle itself has a hanging aesthetic that doesn’t hassle to cover the actuality that this is maybe the most technologically highly developed design you’ll see this calendar year. The body was made by Mathis Heller who has working experience with BMW and IKEA among other individuals, and it’s pure curves and racing traces. The stealth bomber search is even further enhanced with all the cables concealed from see inside the body. The Urtopia is pitched as a town bike and even though the (detachable) battery isn’t extremely clear, there is no question to even the most informal of glances that you are not wielding a regular analog pedaller.

When this point arrived, I was dreading putting it with each other. Previous experience has taught me that while not complicated, you are going to want to set apart some time (and space) to get factors established up. Turns out, the prototype product I analyzed only really necessary the front wheel inserted and the tires pumped and I was fantastic to go.

The noticeable attract here for gadget lovers will be the “smartbar” — an onboard computer developed proper into the handlebars. The dot matrix display is the centerpiece of the bicycle and only dials up that “bike from the future” vibe. On the right-hand facet in which the bell would usually be is the fingerprint reader which interacts with the laptop in a couple ways (it’s also a electronic bell). The remaining-hand side homes the 4-way D-pad which is where by you transform modes and settings together with powering the bicycle on (but not off, additional on that later on).

In spite of that extensive listing of wise attributes, not all of them were being offered to take a look at on the prototype I was sent. The hardware for the mmWave sensors is there, but there’s no way to activate it. The GPS and eSIM have to have the companion application to get the job done and that is not prepared still also. Sadly, those people are some incredibly exciting features we’ll have to wait around and see on, but most everything else was existing and correct.

Ahead of the enjoyable things, the essential e-bike operation (ability/speeds/vary

Enel CEO skeptical of carbon seize and storage technological innovation

The CEO of multinational Italian strength company Enel has expressed question on the usefulness of carbon capture and storage, suggesting the technology is not a climate solution.

“We have tried and experimented with — and when I say ‘we’, I imply the electric power industry,” Francesco Starace explained to CNBC’s Karen Tso on Wednesday.

“You can think about, we tried out challenging in the previous 10 several years — it’s possible far more, 15 many years — simply because if we had a trustworthy and economically attention-grabbing resolution, why would we go and shut down all these coal vegetation [when] we could decarbonize the method?”

The European Fee, the EU’s govt arm, has described carbon capture and storage as a suite of technologies concentrated on “capturing, transporting, and storing CO2 emitted from ability plants and industrial facilities.”

The idea is to stop CO2 “achieving the atmosphere, by storing it in appropriate underground geological formations.”

The Fee has reported the utilization of carbon seize and storage is “important” when it arrives to encouraging lessen greenhouse gasoline emissions. This see is primarily based on the competition that a considerable proportion of equally business and electric power era will nevertheless be reliant on fossil fuels in the decades ahead.

Enel’s Starace, however, seemed skeptical about carbon capture’s probable.

“The fact is, it won’t do the job, it has not labored for us so much,” he reported. “And there is a rule of thumb here: If a know-how will not definitely pick up in five decades — and here we’re talking about more than 5, we are talking about 15, at minimum — you better drop it.”

There are other local weather solutions, Starace claimed. “Fundamentally, halt emitting carbon,” he said.

“I’m not expressing it is not value seeking yet again but we are not likely to do it. It’s possible other industries can consider more challenging and realize success. For us, it is not a solution.”

Carbon capture technological innovation is normally held up as a supply of hope in minimizing worldwide greenhouse fuel emissions, showcasing prominently in countries’ climate strategies as well as the web-zero approaches of some of the world’s biggest oil and fuel businesses.

Proponents of these technologies believe they can engage in an critical and varied part in conference international energy and weather ambitions.

Local climate researchers, campaigners and environmental advocacy teams, however, have extensive argued that carbon seize and storage technologies extend the world’s fossil gas dependency and distract from a a lot-essential pivot to renewable alternatives.

Options to raise shareholder dividends

Starace was talking following Enel published a strategic approach for 2022-24 and laid out its aims for the decades ahead. Among other issues, Enel will make direct investments of 170 billion euros ($190.7 billion) by 2030.

Immediate investments in renewable energy assets that Enel will own are set to strike 70 billion euros. Consolidated mounted renewable capacity, or potential that is immediately owned by Enel,

Carbon nanotubes could help electronics withstand outer space’s harsh conditions

Space missions, such as NASA’s Orion that will take astronauts to Mars, are pushing the limits of human exploration. But during their transit, spacecrafts encounter a continuous stream of damaging cosmic radiation, which can harm or even destroy onboard electronics. To extend future missions, researchers reporting in ACS Nano show that transistors and circuits with carbon nanotubes can be configured to maintain their electrical properties and memory after being bombarded by high amounts of radiation.

The lifetime and distance of deep space missions are currently limited by the energy efficiency and robustness of the technology driving them. For example, harsh radiation in space can damage electronics and cause data glitches, or even make computers break down completely. One possibility is to include carbon nanotubes in widely used electronic components, such as field-effect transistors. These single-atom-thick tubes are expected to make transistors more energy efficient compared to more run-of-the-mill silicon-based versions. In principle, the ultra-small size of the nanotubes should also help reduce the effects that radiation would have when striking memory chips containing these materials. However, the radiation tolerance for carbon nanotube field-effect transistors has not been widely studied. So, Pritpal Kanhaiya, Max Shulaker and colleagues wanted to see if they could engineer this type of field-effect transistor to withstand high levels of radiation, and build memory chips based on these transistors.

To do this, the researchers deposited carbon nanotubes on a silicon wafer as the semiconducting layer in field-effect transistors. Then, they tested different transistor configurations with various levels of shielding, consisting of thin layers of hafnium oxide and titanium and platinum metal, around the semiconducting layer. The team found that placing shields both above and below the carbon nanotubes protected the transistor’s electrical properties against incoming radiation up to 10 Mrad—a level much higher than most silicon-based radiation-tolerant electronics can handle. When a shield was only placed beneath the carbon nanotubes, they were protected up to 2 Mrad, which is comparable to commercial silicon-based radiation-tolerant electronics. Finally, to achieve a balance between fabrication simplicity and radiation robustness, the team built static random-access memory (SRAM) chips with the bottom shield version of the field-effect transistors. Just as with experiments performed on the transistors, these memory chips had a similar X-ray radiation threshold as silicon-based SRAM devices.

These results indicate that carbon nanotube field-effect transistors, especially double-shielded ones, could be a promising addition to next-generation electronics for space exploration, the researchers say.
