Solarflux, a company specializing in parabolic dish concentrator technology, has developed the FOCUS parabolic dish concentrator, which converts 72% of the solar energy it gets into usable heat. This news comes from Solarflux, which just announced the results of an independent report by Lehigh University’s Energy Research Center. The report was conducted in close accordance with the methods outlined in the ASTM 905-87 industry standard relating to solar concentrators.

The report reviewed the Solarflux FOCUS parabolic dish concentrator’s performance test results. It showed that the device demonstrated solar-to-thermal conversion efficiency of 72%, meaning that once solar energy arrives at the FOCUS, 72% of it is converted into usable heat.

The company noted that its solar-to-conversion efficiency is comparable to best-in-class solar-to-thermal conversion performance from alternative concentrating solar power (CSP) systems such as parabolic troughs. The difference, however, is that the FOCUS is a full, two-axis tracking device that is able to maintain perfect alignment with the sun from dawn until dusk at all latitudes.

This enables the delivery of maximum conversion efficiency throughout the day and year-round, which reportedly gives the FOCUS a significantly higher annual energy yield than alternative CSPs. FOCUS has outperformed parabolic troughs by up to 50% or more depending on the system’s peak capacity and site location.

The new FOCUS dish seems to offer a low-cost, low-maintenance, zero-emission modular thermal energy solution that can be used in a variety of ways. These include:

  • Industrial process heat.
  • Water desalination and purification.
  • Space heating and cooling.
  • Hot water.
  • Remote power generation.

I had a quick chat with Solarflux CEO and founder Naoise Irwin, who said:

“This report provides independent confirmation of what we have long known — that the FOCUS solar concentrator is the highest performing solar technology out there.

“With a low lifetime cost of energy and room for further performance improvements, we are excited about the prospects for the FOCUS.”

The FOCUS is said to have a small physical footprint relative to other solar energy technologies. The company says that its thermal energy storage solution is around 1/10th of the price of battery storage, which allows FOCUS to be used to power nighttime operations sustainably at a low cost, and in remote locations.

It’s made up of mostly aluminum and steel and is highly recyclable. It doesn’t have an e-waste problem or toxic substances to manage at the end of its life. The thermal energy that FOCUS produces can be used for many things. Irwin pointed out, as well, that many of these uses can be helpful to mining companies of various sorts — due to the efficiency and capability in remote locations as well as the diversity of uses.

Earlier this spring, Solarflux shared a blog post titled, “The Promise of Parabolic Dish CSP Technology,” which pointed out that parabolic dishes are commonly understood as the most efficient concentrating solar power CSP technology and noted that the promise has been long recognized.

The article described some of the challenges that CSP has faced as an industry over the past decade, but explained that the Solarflux team earnestly believes that CSP, especially the parabolic dish, has significant potential, most notably as a distributed solar thermal (versus electrical) energy technology. Citing the IEA, the article pointed out that heat is the largest energy end-use and it accounts for over 50% of energy consumption. Half of this is used by industry, with a balance used for space and water heating (think cooking in homes and buildings) and agriculture with only around 10% of the heat being provided by renewable technologies.

Another large energy consumer mentioned was air conditioning, which accounts for up to 27% of home energy consumption in parts of the US. Mine is definitely in that number — heat domes are not fun! Solarflux noted that air conditioning can be more energy efficient if it uses a thermal energy source along with an absorption chiller. You can read more here.

Costco Executive members get MASSIVE $31,500 off Chevy Brightdrop van

Costco Executive members get MASSIVE ,500 off Chevy Brightdrop van

With 272 miles of range and more room inside its walls than your first apartment, GM’s Chevy Brightdrop electric van is one of the best commercial EVs you can buy. And if you’re a Costco Executive member, you can get one for yourself or your business with an absolutely incredible $31,500 discount. (!)

Fleet electrification expert Tony Nisam took to LinkedIn yesterday to post a deal that he ran across at a Washington State Costco that stacks a $25,500 manufacturer rebate with $3,000 in “regular” Costco Member Savings, $2,750 in “LIMITED-TIME” Manufacturer to Member Incentives, plus an additional $250 for Costco Executive members.

Do a bit of math (add up 25,500 + 3,000 + $2,750 + 250), and you’ll calculate an almost unheard of $31,500 discount on one of the best, most capable commercial vans on the market – ICE or electric. And that’s before you factor in the 0% interest financing (72 mo.) being advertised at Blade Chevrolet, the Mount Vernon, Washington, where VIN 2G58J2TY6S9104313 (the exact van shown, below) is shown as stock number 16757.

If you’re not a Costco member yet and you’re looking for a new truck for your business or even a unique #vanlife ride with zero emissions, modern tech, and a nationwide dealer network, GM makes that $130 Executive membership seem like a no-brainer.

Kind of a big deal

“But wait,” says the floating, disembodied ghost of the great Billy Mays. “There’s more!” In addition to the $31,500 worth of discounts Costco Executive members get, there are deals to be had on chargers AND a number of other state and local utility incentives your business might qualify for, bringing the cost of adding a new Chevy Brightdrop to your fleet even lower. In northern Illinois, for example, ComEd commercial customers can get up to $7,500 in rebates for a new Brightdrop Zevo van.

Is a $39,000 price cut enough to get you to take a look at a new Brightdrop? At $45,235 (from a starting price of $84,235), can you afford not to? Head down to the comments and let us know.

Tesla quietly removes range extender battery option on Cybertruck

Tesla quietly removes range extender battery option on Cybertruck

Tesla has quietly removed the Cybertruck’s range extender from the options in its online configurator.

Does Tesla still plan to bring the product to market?

When Tesla unveiled the production version of the Cybertruck in late 2023, there were two main disappointments: the price and the range.

The tri-motor version, which was the most popular in reservation tallies, was supposed to have over 500 miles of range and start at $70,000.

Tesla now sells the tri-motor Cybertruck for $100,000 and only has a range of 320 miles.

As for the dual-motor Cybertruck, it was supposed to cost $50,000 and have over 300 miles of range. The reality is that it starts at $80,000, and it has 325 miles of range.

However, Tesla had devised a solution to bring the range closer to what it originally announced: a separate battery pack that sits in the truck’s bed. Tesla called it a “range extender.” It costs $16,000 and takes up a third of the Cybertruck’s bed.

Even though the Cybertruck has been in production for a year and a half at this point, the range extender has yet to launch.

Initially, Tesla said that it would come “early 2025”, but we reported that it was pushed to “mid-2025” late last year.

At the time, Tesla also reduced the range that the removable battery pack adds to the Cybertruck to “445+ miles” rather than “470+ miles” for the dual motor – a ~25-mile reduction in range.

Now, Tesla has removed the option from its online Cybertruck configurator. It used to take reservations for the range extender with a “$2,000 non-refundable deposit”, as seen on the image above, but now it’s not in the configurator at all at the time of writing.

It’s unclear if Tesla is not planning to launch the product anymore or if it is just pausing reservations.

In its specs page, Tesla still lists the achievable range of both versions of the Cybertruck with and without the range extender battery:

Electrek’s Take

I’m curious. Is it dead, or does Tesla just want to stop taking reservations for it?

At first, I was curious about the product even though I didn’t think it would make up for Tesla’s significant miss on Cybertruck specs.

However, after it was confirmed that it takes up 30% of your bed and that it needs to be installed and removed by Tesla at a service center, I think it’s pretty much dead on arrival at $16,000.

It’s going to be a product limited to only a few people at best. And now that’s if it makes it to market.

With the option being removed from the configurator, there’s no production timeline available. Again, the last one was “mid-2025”, which is soon.

This fund most recently provided aid for communities affected by the recent Los Angeles wildfires, assistance to the Special Forces Charitable Trust (SFCT) in North Carolina following severe hurricanes, and support for non-profits engaged in hurricane preparedness in Florida and the Gulf Coast. Per Jodi Burns, CEO of the Special Forces Charitable Trust:

In the wake of devastating storms in Western North Carolina, reliable power was a critical need for the families we serve. Thanks to EcoFlow’s generous donation of generators, we were able to provide immediate relief, ensuring these families and their communities had access to power when they needed it most. We are so impressed with EcoFlow’s commitment to disaster response through their ‘Power for All’ program. It has made a tangible impact, and we are deeply grateful for their support and partnership in helping these families recover and rebuild.

In 2024, the US experienced 27 weather and climate events, each causing losses exceeding $1 billion, marking the second-highest annual total on record, according to National Centers for Environmental Information. The increasing frequency and severity of natural disasters underscore the critical need for reliable and timely power solutions during emergencies, much like EcoFlow and its members are helping provide through the “Power For All” initiative.

To support new and existing EcoFlow members, the company is celebrating its third annual Member’s Festival throughout April to offer a do-not-miss discount on its products and donate a portion of all sales to the “Power for All” fund to provide rescue power to those in need in the future. Learn how it all works below.
