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.

Seventeen state attorneys general and DC are fighting a Trump executive order that froze permits and funding for all onshore and offshore wind projects on January 20.
The coalition is asking a federal judge to declare the executive order illegal and prevent the Trump administration from obstructing wind energy development. It was filed in federal court in Massachusetts.
New York attorney general Letitia James is leading the coalition. James said, “This arbitrary and unnecessary directive threatens the loss of thousands of good-paying jobs and billions in investments, and it is delaying our transition away from the fossil fuels that harm our health and our planet.”
Federal agencies have stopped issuing permits for wind projects across the board and even pulled the plug on the fully approved Empire Wind in New York, which was already under construction. Developer Equinor, majority owned by the Norwegian government, went through a seven-year permitting process and is considering separate legal actions.

Massachusetts attorney general Andrea Joy Campbell said that Trump’s “attempts to stop homegrown wind energy development directly contradict his claims that there is a growing need for reliable domestic energy.”
The coalition argues that the action violates the Administrative Procedure Act and other federal laws because the Trump administration, “among other things, provides no reasoned explanation for categorically and indefinitely halting all wind energy development.”
Trump’s executive order puts billions of dollars in state investments at risk, jeopardizing everything from wind industry infrastructure to supply chains and workforce training that’s already well underway.
The coalition consists of attorneys general of Arizona, California, Colorado, Connecticut, Delaware, District of Columbia, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Jersey, New York, New Mexico, Oregon, Rhode Island, and Washington.

Professional salespeople love to talk about “the steps of the sale,” a tried-and-true process that guides every customer from curiosity to closed. But when it comes to electric cars, that old-school hustle can fall flat, leaving dealers struggling with how to fit them into their familiar playbook. But what if I told you, dear dealer, that there’s a whole category of vehicles on existing dealer lots that need to be approached in exactly the same way as an EV to score a successful sale that you’re already familiar with?
That category: Heavy-duty tow trucks. Here’s how selling one is a lot like selling the other.
That’s right, greenpeas – selling a tow-rated pickup truck to someone who’s buying it primarily to haul a trailer, boat, or RV is a delicate thing that requires salespeople (and sales managers) to approach their customers with a lot more patience and empathy, and a lot less, “what can I do to get you to drive this home, today?” And, as we go through the whys and hows, I think you’ll agree that all the heavy truck selling wisdom we’re going to cover today will help you sell more electric cars, more often, and for more money.
1. Discovery is where the deal gets done
When it comes to heavy-duty tow vehicles, most smart dealers understand that their customer probably has a better understanding of their individual needs than they do – but it’s still a good idea to go over that understanding during the discovery phase of the sale.
Advertisement – scroll for more content
Has the customer factored in the weight of the trailer and the weight of everyone and everything else inside it? What about the weight of water, tools, or animals? Do they fully understand the concepts of GVWR and GCWR, and the difference between trailer weight and tongue weight? Will they have enough range, when fully loaded, on their standard fuel tank or will they need an aux. tank? What about the future – are they thinking about upgrading their RV or hauling bigger loads longer distances?
In other words, the customer has to trust that the vehicle they’re about to buy from you will meet their needs and fit into their lives today, while also meeting their needs in the foreseeable future. That’s what it looks like in a truck, but now apply that to an EV.
Has the customer mapped out the routes they take every day to make sure they can make the drive? That might sound ridiculous to you and me, but what if they’re depending on a single DC fast charger out on a rural stretch of highway to get the EV to meet their needs? What if they think 200 miles of range is 200 miles of range, but they like to drive 80+ mph (on Chicago’s I-290, that’s a minimum safe travel speed), do they understand that speed impacts range as much as weather?
Tools like Chargeway are great for helping dealers explain EV charging speeds, the impacts of speed and topography on range, and – especially in this era of NACS adapters – where buyers of used or off-lease EVs can charge up and get back on the road.
In either case, the salespeople who take the time in discovery to understand their customers’ needs and become consultative partners will make a sale, the ones who rush through the process won’t, and the ones who sell their customers the wrong thing will make a problem (if not an expensive lawsuit) for the dealership.
2. Options really do matter
When you’re selling a conventional ICE-powered crossover to a typical suburbanite, moving your customer up or down a trim level doesn’t typically impact their use case. Sure, they might have to keep their foot planted a little longer to get up to highway speeds or learn to live with cloth when they really wanted leather or vinylvegan leather, but they’ll still be able to get five-to-seven adults from point A to point B with the same general effectiveness.
That’s not true when it comes to trucks that are going to get put to work. There, the difference between one axle ration and another can have a huge impact on driver comfort, towing capabilities, and fuel economy – and going from a one-ton truck that’s just outside the customer’s budget to a half-ton that you happen to have on the lot could get someone seriously hurt or killed.
It may be tempting to switch the customer to a vehicle you have on the lot (especially if that vehicle happens to be an aged unit with a fat spiff on it), but the long-term pain isn’t worth the short-term gain on this one.
3. Information is your friend
This might feel like a duplicate of the discovery phase, but think of it as a member of the “measure twice, cut once” advice genre. That is to say that, sure – the customer thinks that new 5th wheel RV they have on order weighs 11,000 lbs., but does it? Did they add any options of features (see no. 2) that make it heavier? Get the information from the RV manufacturer or dealer and confirm as much as you can. That extra work will help keep your customer safe and build trust.
Similarly, you’ll want to verify your assumptions when it comes to EVs. Is that once-a-month 300 mile drive really 300 miles, or is it 330? Is there more than one charging option available on their preferred route? Is the customer able to make their trip without changing the way your they drive? Are they willing to change up where they stop, or for how long?
When it comes to EVs, especially used ones that came onto your lot as part of a trade deal that you may not be intimately familiar with, I cannot stress how much route planning apps like Chargeway or A Better Route Planner can help salespeople answer questions about electric vehicles confidently and correctly, generate trust, and drive referrals.
4. Aftersales support is critical
Successful salespeople follow up – not just with prospects who are still shopping, but with customers who have already bought. And, just as RVers know other RVers, RV salespeople who get positive feedback about a local dealer who takes the time to make sure their customers get the right truck know RV customers who might need a right truck of their own.
Yes, those RV salespeople might expect a $100 bird dog bonus to send their customers your way, but the money on its own isn’t enough. They have to know they can trust you with their customers, and you build that trust in steps 1-3, above.
The reason BMW is consistently pulling ahead? It seems to come down to education. “First-time EV buyers are receiving minimal education or training,” explains Brent Gruber, executive director of the EV practice at J.D. Power. “Dealer and manufacturer representatives play the crucial role of front-line educators, but when it comes to EVs, the specific education needed to shorten the learning curve just isn’t happening often enough. The shortfall in buyer education is something we’re seeing with all brands.”
And, if you’re still not quite convinced that you need to learn how to sell EVs to be successful on the sales floor, think again.
Overall, 94% of BEV owners are likely to consider purchasing another BEV for their next vehicle, a rate that is also matched by first-time buyers. Manufacturers should take note of the strong consumer commitment to EVs as the high rate of repurchase intent offers the ability to generate brand loyal customers if the experience is a positive one. In fact, during the past several years, the BEV repurchase intent percentage has fluctuated very little, ranging between 94-97%. This year’s study also finds that only 12% of BEV owners are likely to consider replacing their EV with an internal combustion engine (ICE)-powered vehicle during their next purchase.
Listen to an EV convert who has desked an awful lot of car deals, greenpeas – if you treat every EV customer the same way that crusty old fleet rep treats his truck buyers, you’re going to sell a whole lot of EVs. And, if you’re a brave enough little toaster to follow up and ask for that referral, you’ll find that EV buyers know other EV buyers.

There’s no exact way to track Tesla’s inventory in the US, but there are ways to track Tesla’s Cybertruck listings. Sometimes, Tesla may have many vehicles with the exact same configuration at the same location and it will only publish a single listing for it.
Therefore, Tesla might have been sitting on more Cybertruck inventory.

A month later, the number of listings in the US has skyrocketed to over 10,000 Cybertrucks, according to Tesla-Info.com:
This surge could be due to an actual net increase in Cybertruck inventory, but Tesla is also heavily discounting the trucks at varying rates, creating several different prices and, therefore, more listings.
At an average sale price of $78,000, Tesla could have almost $800 million worth of Cybertrucks.
Due to low demand, Tesla appears to have significantly slowed down Cybertruck production in recent months. Therefore, this surge is likely more about Tesla discounting the vehicles, exposing the broader US inventory, than an actual major increase in inventory due to more production.
Many of the Cybertrucks in inventory were built in 2024, so they are already at least four months old. Tesla still has ‘Foundation Series’ Cybertrucks in inventory, which it stopped producing in October 2024—more than seven months ago.
This is about as bad as it gets. Over 10,000 units account for about two quarters of Tesla’s Cybertruck sales.
It already looks like Tesla has slowed Cybertruck production down to a crawl, but I wouldn’t be surprised if it pauses it soon. The hard part for Tesla is to admit defeat.
The Cybertruck RWD using the same battery pack as the AWD was already a sort of admission that Tesla found the vehicle program to be too small to be worth being produced with two battery pack sizes. The automaker did the same with Model S/X when the program’s volumes shrank following the launches of Model 3 and Model Y.
It looks like under the current circumstances, Tesla will have issues selling more than 20,000 Cybertrucks per year in the US despite having planned production for 250,000 units.
