Zero Motorcycles Introduces New Game-Changing SR/F Model with 110 horsepower, 200-mile range and Internet connectivity to "find my bike"

Zero Motorcycles is not waiting around for Harley-Davidson to figure out how to make an electric motorcycle. The company has been doing it for the past 13 years. Any comparison between what Zero has done to the motorcycle industry and what Tesla has done to the automotive industry is strictly intentional.

The SR/F alerts riders regarding bike status, including interruptions in charging and tip-over or unexpected motion notifications. In addition, the “Find my Bike” function allows riders to keep tabs on the motorcycle at all times.

The SR/F takes the convenience of recharging to new levels with the ability to remotely set charging parameters, including Targeted Charge Levels, notification of State of Charge, Charge Time Scheduling, and Charge Tracking. These notifications allow riders to control all aspects of charging and to monitor charge status even when away from the motorcycle.

Riders can gather, relive, and share extensive data about their ride through the app. An industry first, the motorcycle records bike location, speed, lean angle, power, torque, SoC, and energy used/regenerated. Riders can replay each ride and also choose to upload additional content to record and share their full experience. Riders also have the option to keep data anonymous.

New updates and diagnostic capabilities allow the rider to remotely download the latest Cypher III operating system release to ensure optimal performance and provide access to feature improvements.

They're not cheap at around $18,000 to $20,000 but Zero has certainly set themselves apart from the pack.

The advent of cheap, renewable hydrogen is nigh - And cheap wind turbine generation may bring on the hydrogen fuel cell revolution

Hydrogen gas has been the pipe dream fuel of clean-energy advocates for decades. Splitting electrons from H2 molecules creates electricity and a waste product: pure H2O. It has the added benefit of being storable (albeit at high pressures or low temperatures), and it can refuel a car or a generator in minutes, as opposed to batteries, which can take hours to recharge.

Unfortunately, most of the hydrogen that is mass-produced today is made by synthesizing it from natural gas (more specifically, methane, or CH4). But it's also possible to make hydrogen using electricity and water, using an electrolyser. If that electricity is renewable electricity, hydrogen can be nearly carbon neutral in its lifecycle.
The problem is that the electrolysers that can make hydrogen from renewable energy have historically been prohibitively expensive. But that's changing, according to a new paper in Nature Energy.

Researchers from universities in Germany and at Stanford University created a financial model for a wind farm connected to a hydrogen electrolyser. They modeled electricity and hydrogen prices as if this theoretical system were based in Germany and then in Texas. The researchers concluded that "renewable hydrogen is projected to become cost competitive with large-scale fossil hydrogen supply within the next decade."

5G routers could download at speeds faster than many solid state drives' write speeds

5G routers could download at speeds faster than many solid state drives' write speeds

The Balong 5000 chipset can deliver theoretical maximum download speeds of 4.6Gbps on sub-6GHz bands, although its expected top speed on a live network should reach around 3.2Gbps.

At these speeds, a 1GB HD video clip can be downloaded in three seconds and 8K video can be streamed smoothly without lag.

Additionally, the chipset can deliver download speeds of up to 6.5Gbps on mmWave spectrum, easily outpacing current 4G connections by a factor of 10.

This peak download speed would result in a real download rate of 812.5MB/s, which is higher than the read and write speeds of many solid state drives.

In fact, at these speeds it is often the hardware or interface between components in your client device which limits download and upload rates.

For example, if you were to connect to a Huawei 5G CPE Pro router in your home over Wi-Fi 6, you could receive a download speed of 4.6Gbps.

However, if you tried to download a file at this speed – 575MB/s – to a typical 2.5-inch SATA SSD, your download rate would be limited by the write speed of the SSD, which is up to 520MB/s.

The speeds provided by Huawei’s Balong 5000 chipset and the 5G hardware are astounding, but they do require sufficient network capacity and coverage in your area, and the Internet server to send the data at this speed.

South African Government turns to renewable energy as state utility Eskom breaks down

South African Government turns to renewable energy as state utility Eskom breaks down

With South Africa’s state electricity utility in dire financial straits and straining to meet demand, the government has reverted to courting independent renewable energy producers to help power the continent’s most industrialized economy.

President Cyril Ramaphosa, his Energy Minister Jeff Radebe and the Treasury have all recently heralded solar and wind-powered plants as the answer to meeting South Africa’s future electricity demands, citing falling costs and environmental considerations. The government also needs private investors to help fund new infrastructure: Eskom Holdings SOC Ltd., which generates about 95 percent of the nation’s power, can’t afford to maintain its aging coal-fired plants, never mind build new ones, and the Treasury has no cash to spare.

Renewable energy companies have reason to be skeptical. South Africa initiated one of the world’s most successful renewable-power programs starting in 2011, which garnered more than 200 billion rand ($14.4 billion) in investment from 112 producers. But projects were stalled for almost three years during ex-President Jacob Zuma’s rule as he and Eskom officials pushed to build nuclear plants, a deal that was tainted by corruption allegations and was shelved when Zuma was forced to step down a year ago.

“They’re putting things right,’’ said Mike Rossouw, an independent energy adviser. “The renewables outlook is getting better and better.

That’s imperative because financiers are becoming increasingly reluctant to fund coal-fired projects, amid a global move toward more environmentally friendly forms of energy, according to Radebe.

The Energizer Power Max P18K Pop - This 18,000mAh battery has a phone in it

But seriously many people prefer battery life over something ultra thin and bendable. Why can't phones come in an ultra long life version (thicker) versus those who want ultra thin with less battery life?

Avenir promises a week’s worth of use, or two full days, 48 hours, of continuous video playback. It measures in at 18mm of thickness.

Rain, Huawei launch first commercial 5G network in SA, and one of the first in the world

South Africa's mobile data-only network operator, Rain, has announced that it has launched the first 5G commercial network in South Africa in partnership with Huawei. Rain and Huawei made the announcement at Mobile World Congress (MWC) 2019 in Barcelona, Spain making it the first network to launch 5G on the African continent, and one of the first in the world.

In November 2018 Rain demonstrated its 5G capabilities in Cape Town and told ITWeb that it had plans for a commercial 5G service to be live in early 2019.

Rain now says that full commercial rollout is only planned for mid-2019 but that its 5G network is actually already live in Johannesburg at the moment. "The network will provide fibre-like speeds without the installation complexities, time delays and cost of laying fibre in under-serviced areas", said Rain group CEO Willem Roos.

Android Is Helping Kill Passwords On A Billion Devices By Adopting Certified Support For The FIDO2 Standard

The FIDO Alliance — a consortium that develops open source authentication standards — has pushed to expand its secure login protocols to make seamless logins a reality. Now Android's on board, which means 1 billion devices can say goodbye to passwords in more digital services than seen before.

The vast majority of devices running Android 7 or later will now be able to handle password-less logins in mobile browsers like Chrome. Android already offered secure FIDO login options for mobile apps, where you authenticate using a phone's fingerprint scanner or with a hardware dongle like a YubiKey. But FIDO2 support will make it possible to use these easy authentication steps for web services in a mobile browser, instead of having the tedious task of typing in your password every time you want to log in to an account. Web developers can now design their sites to interact with Android's FIDO2 management infrastructure.

Cardiogram - Android and iOS app for personal healthcare assistant across Android Wear OS, Garmin and Apple watches

Instead of just using your watch fitness app and losing that data when you switch watch brands, Cardiogram will collate health data from various brands of watch allowing you to switch brands and often retain all your health history.

It also gives a lot more insight into your data than many standard apps do:
• The Timeline tab shows your heart rate each day, with a detailed view for workouts and a special interface to track spikes related to stress, diet, or exercise.
• The Daily Leaderboard lens in the Timeline tab lets you compete steps and activity levels with your friends! You can invite friends who own an Apple Watch or Garmin, or even those who don't own an wearable device at all — this feature is compatible with the built-in Google Fit step tracker on your phone!
• The Metrics tab shows you how your resting heart rate and steps are trending over time.
• And the new Habits tab lets you find a new healthy habit or activity you'll love, invite a friend to share metrics, and optimize your overall health, sleep, stress, and fitness.
• Not only that, there's a larger purpose: you can share your health data with medical researchers, to contribute to studies on sleep apnea, diabetes, hypertension, or abnormal heart rhythms like atrial fibrillation.

Why not Fitbit? Well as I recall from hearing in developer forums Fitbit only shares very limited data via their API for developers and no live API data from the device. What a pity!

It'sd not perfect though as its sleep measurement seems to come from a rudimentary way the Apple watch figures out when it was last interacted with in the evening versus first used in the morning, and no Android detection for sleep - so it's not using auto-sleep detect as Fitbit does from movement.

But still, I like the aggregated approach across devices.

LG Watch Sport band splitting after 1 year and 7 months - Lesson is beware of buying devices without...

LG Watch Sport band splitting after 1 year and 7 months - Lesson is beware of buying devices without easily replaceable bands and batteries

I bought this watch in July 2017 at quite a cost as it had to be shipped out from the USA with the extra VAT and duty payable on arrival in South Africa. So 19 months later the band is seen splitting. The band contains the Wifi, Bluetooth and LTE antennas and there are not even easy to obtain replacements without the antennas. One place in Korea sells them at $70 each. The lesson is don't buy devices that do not have easily replaceable bands or batteries!

The warranty is usually a year (or a major struggle to get something replaced and this would be chalked up to "wear and tear").

But I've learnt from early Fitbit purchases too that the first big thing to look at is standard type strap/band replacements. Fitbit bands seem to last just on 13 months and then start splitting (I bought the newer Charge 2 since with easy to replace bands) and this LG is especially bad with its antennas in the band. I took it to a watchmaker and he just laughed and said I should buy a "proper" watch if I want it to last - he could put another strap on but the watch would have a gaping hole with its antenna connectors all open. A proper watch though does not have my grocery list on! So I've ordered the Ticwatch Pro now which has standard 22mm bands, and ordered an extra leather band with it.

On batteries my lesson was nearly learnt with my Nexus 6P phone. Fantastic phone with a dead battery after 1 year. I bought all the tools to replace it including a heat gun to melt the case off, and the replacement battery also dies after a few months. Easy to replace batteries are also just a blessing.

So remember that replaceable straps, batteries and microSD card slots (yes OK also headphone plugs for many) are to be valued when it comes to comparative specifications when choosing new devices.

Mounted a Watson W-30 Dual-Band Base Colinear 2m 1/2 wave 70cm 2x 5/8 wave antenna today

Mounted a Watson W-30 Dual-Band Base Colinear 2m 1/2 wave 70cm 2x 5/8 wave antenna today

So my second DIY VHF/UHF suffered during some gusting winds and the vertical bend down. The problem is not so much my construction as it is the very weak centre pin on the SO239 connector. The pin was just not strong enough to hold the 3mm bronze rod upright.

So I decided to buy a not too expensive commercial antenna for the outside use. I do probably need to give this antenna a better mounting pole as it is slightly heavier than my DIY antenna (so it is now not too high up yet), but the difference is already noticeable with the new antenna being a 1/2 wavelength over my DIY one which was a 1/4 wavelength on VHF. The antenna has 3dB gain on 144MHz and 6dB gain on 430MHz. As I'm not yet transmitting I have not tested the SWR yet but it is reputed to be below 1.5:1.
