RWE Renewables and Kansai Electric Power have signed an agreement that will see the two businesses “jointly study the feasibility of a large-scale floating offshore wind project” in waters off Japan’s coast.

In a statement issued Monday, RWE Renewables’ Sven Utermöhlen said his firm saw “great potential for floating wind farms worldwide — but especially in countries with deeper coastal waters, like Japan.”

Indeed, the project announced Monday is not the only one in Japan focused on floating offshore wind. In July, self-described “cleantech company” BW Ideol said it had signed a joint development agreement with energy firm ENEOS Corporation to develop a “commercial-scale floating offshore wind farm” in waters off Japan’s coast.

In June, authorities in Japan said a consortium made up of six companies — Toda Corporation, Osaka Gas, Kansai Electric Power, ENEOS Corporation, INPEX Corporation and Chubu Electric Power — had been selected to develop a 16.8 megawatt floating offshore wind farm in waters off the coast of Goto City, Nagasaki Prefecture. There were no other bidders for the project.

Floating offshore wind turbines are different to bottom-fixed offshore wind turbines that are rooted to the seabed. By contrast, RWE describes floating turbines as being “deployed on top of floating structures that are secured to the seabed with mooring lines and anchors.”

One advantage of floating turbines is that they can be installed in deeper waters compared to bottom-fixed ones. As the Carbon Trust, an advisory firm, notes: “Sites further from shore … tend to benefit from more consistent wind resource, meaning floating wind can deliver higher yields.”

Floating offshore wind is still in its early stages of development and costs will need to be driven down going forward. It was only in 2017 that Norwegian energy major Equinor — a major player in oil and gas — opened Hywind Scotland, a 30 megawatt facility it calls “the first full-scale floating offshore wind farm.”

For its part RWE, which is headquartered in Germany, is already undertaking work on three demonstration projects in Spain, the U.S. and Norway. It’s also looking into whether bottom-fixed offshore wind projects are feasible in parts of Japan.

In another announcement, also issued on Monday, RWE said it would be reorganizing its renewables business. Under the new structure, its offshore and onshore renewables businesses will be managed separately. Utermöhlen will have responsibility for RWE’s offshore wind division, with Silvia Ortín Rios heading up onshore wind and solar photovoltaic.

The collaboration between RWE and Kansai Electric Power comes after Japan’s Ministry of Economy, Trade and Industry published a draft of its sixth Strategic Energy Plan last month.

According to research and consultancy firm Wood Mackenzie, the draft included “major changes” to the country’s targets for its power generation mix in the fiscal year 2030.

“Included in the draft targets is a significant increase in renewable and nuclear shares of the generation mix and hydrogen/ammonia is mentioned for the first time,” Lucy Cullen, a principal analyst at Wood Mackenzie, said in a statement at the end of July.

Such a plan is not without its hurdles. “Our current outlook for renewables is a 30% share by 2030, so the proposed 36% renewables share is a stretch,” Cullen said, referencing the draft’s goal for renewables to have a 36% to 38% share in the power generation mix. “It can only be possible with additional government support.”

Of the draft’s nuclear target, Cullen called it “perhaps the most critical and uncertain component.”

“METI continues to back nuclear and maintains the previous 20-22% target,” she said. “Safety regulations, on-going opposition and rising costs continue to plague restarts to date and make this an incredibly challenging target to meet. The outlook for restarts remains highly risked in our opinion.”

Elon Musk claims that Tesla's always 'coming next year' Roadster can fly

Elon Musk is again claiming that Tesla’s always “coming next year” Roadster will be able to fly.

The prototype for the next-generation Tesla Roadster was first unveiled in 2017, and it was supposed to come into production in 2020, but it has been delayed every year since then.

It has become a sort of running joke, and there are doubts that it will ever come to market despite Tesla’s promise of dozens of free new Roadsters to Tesla owners who participated in its referral program years ago.

But earlier this year, CEO Elon Musk made some rare new comments about the next-gen Tesla Roadster, reviving hope that the vehicle will finally happen.

Musk said that Tesla will unveil a much-needed updated version of the next-gen Roadster since the design of the yet-to-be-revealed vehicle is already 7 years old, and he said that vehicle would come to market in 2025.

We haven’t heard anything bout the vehicle since and it wasn’t in Tesla’s shareholders meeting presentation.

Now, Musk has again made a rare new comment about the new Tesla Roadster – saying that it “can fly”:

The CEO had previously talked about an updated version of the new Tesla Roadster with something called ‘SpaceX package’, which would include cold air thrusters that could theoretically make the vehicle “fly”, or rather jump and possibly hover, for short distances.

Electrek’s Take

It’s pretty funny that Elon is responding to a guy using the classic technology complaint that “we were promised flying cars, but they are never coming” with a vehicle that Tesla has been promising every year for the past 4 years.

At this point, the Roadster, like FSD, is something that entered the “put up, or shut up” phase.

Bring it or stop talking about it, especially the flying part. The Roadster was supposed to be the “halo effect” for electric cars. I’m not sure how the cold air trusters play into this.

Tesla Cybertruck deliveries halted amid problem with giant windshield wiper

Tesla Cybertruck deliveries halted amid problem with giant windshield wiper

Tesla has reportedly halted Cybertruck deliveries amid a problem with the motor of its giant windshield wiper.

The Cybertruck is equipped with the biggest wiper put on a consumer vehicle.

It’s the result of Tesla’s design, which aimed to have a straight line from the front-end all the way to the apex of the roof – resulting in nowhere to hide wipers between the hood and the windshield.

Instead, Tesla opted to have a single giant exposed wiper with a vertical resting position for aerodynamic reasons.

In my review of the Cybertruck, I noted that we had some problems with it, like starting on its own for no reason and staying down as a resting position rather than up. However, I chalked this up as being due to Tesla’s notoriously bad auto windshield wiper system, which is common on all Tesla vehicles – not just the Cybertruck.

Now, many Cybertruck buyers are reporting that Tesla has delayed their deliveries, indicating a roughly week-long halt on deliveries, and some were told by Tesla that it had to do with the windshield wiper motor (via Cybertruck Owners Club).

Some buyers were told that Tesla would have to replace the windshield wiper motor on all Cybertruck, but this has yet to be confirmed.

No recall notice has been released yet.

Electrek’s Take

As I previously reported, we had some issues with ours last month when reviewing the Cybertruck.

I chalked it up to the terrible Tesla auto wiper, but now that I think about it, it’s possible that it wasn’t that.

Tesla’s auto wipers are known to start when they shouldn’t and don’t start when they should. The Cybertruck’s wipers were doing that, but they were also starting and stopping at the bottom rather than at the top position and just staying there.

I’m not sure if it has to do with this or if it’s completely unrelated. I expect that we will learn more in the next few days.

E-quipment highlight: Bobcat pitches electric telehandler concept

Bobcat unveiled the all-new TL25.60e electric telehandler concept at Intermat last month, with a 2.5 ton rated capacity, three electric motors, and the promise of unmatched energy efficiency and performance that’s objectively superior to diesel.

The Bobcat TL26.60e gets its energy efficient edge from its “actively cooled” li-ion batteries, which are designed to deliver consistent performance in any weather and help fleet operators maintain low running costs while maximizing efficiency and, as a consequence, savings.

Those batteries send power to three separate electric motors, one each to power drive, the rotating superstructure/cab, and the boom/attachments. Bobcat says the arrangement helps its electric telehandler concept consume energy only when it’s needed, and claims that the setup provides immediate responsiveness for all the machine’s movements. That kind of quiet, vibration-free precision control should make the TL26.60e’s operator cab a great place to work from.

Speaking of the cab, it’s the same one found in Bobcat’s larger TLS models, despite the TL26.60e’s smaller footprint. The compact nature of the the machine’s electric components means there’s room for stuff like that – and, as a consequence, more room for operators.

“At Bobcat, we are committed to innovative design that prioritizes both cutting-edge technology and operator wellbeing,” says Vijay Nerva, Innovation Lead, Bobcat EMEA. “Our integration of ergonomics and digitization, exemplified by the transparent T-OLED screen, allows us to introduce customizable, interactive features without compromising the comfort and spacious design of our cabs.”

The TL26.60e features a top speed of 25 km/h, a 6 meter lifting height, and a 2.5 ton lifting capacity. The liquid-cooled battery has a 30 kWh capacity, which should be good for a full shift at most low-speed job sites.

Electrek’s Take

Bobcat’s electric telehandler concept is still just that, but as more and more construction companies come up agains no-drip job sites, low emissions zones, tightening noise regulations, and the ESG goals of both corporate and government clients, it seems like only a matter of time before machines like this become more the rule than the exception.
