I’ve written about Solarflux, its FOCUS parabolic dish, and its new tool, CASPER, which is a concentrating solar power (CSP) performance comparison tool. I’ve also had the pleasure of sitting down with Solarflux CEO Naoise Irwin and CTO John Fangman, who invented the FOCUS dish. This is the second part of that interview, this time talking about CASPER and how to use it, as well as a few other things.

CASPER

In a nutshell, CASPER is a web-based tool that compares the energy collection and conversion efficiency of the Solarflux FOCUS parabolic dish concentrator with a widely used type of CSP. Naoise explained:

“It’s a tool that compares the output of our system versus parabolic trough, which is the other technology that I’ve talked about. What it’s intended to do is to highlight how much more energy you would get in an equivalent area with FOCUS.

“For example, in Phoenix, Arizona, which is a great place for concentrated solar energy because it has so much sun, you get about 30% more energy using our system versus the trough. So we’re just trying to find a simple way for people to compare.”

Naoise demonstrated CASPER and shared the comparison for Baton Rouge, which receives a similar amount of sun as Phoenix. I was a bit surprised seeing that, as we get plenty of rain here.

“It calculates how much energy you’re capturing throughout the year — for our system and for the trough — and it tells you what the difference is.”

Features Of The Focus Parabolic Dish

Naoise told me that the FOCUS parabolic dish had several unique features. It’s made of aluminum and steel, making it extremely recyclable.

“The fact that it’s made from aluminum and steel makes it recyclable and environmentally friendly, and this is something we really like about it. I love photovoltaics (PV), but one of the issues is what happens to all the PV when it gets to end of life? It needs to be recycled, processed.

“They’re made of silicon and all of this processing has gone into making these panels. So, they’re not that easy to take apart at the end of their life. So, they’re going to probably largely end up in landfills, unfortunately, unless a huge recycling strategy is developed. Kind of like what you’re seeing in EV batteries. You’re seeing a big push to find an effective way to recycle the materials. I really haven’t seen that much done on the PV panels, and this is a concern.”

Photovoltaic Recycling & Developing Strategies

Solarflux’s system is relatively low tech, Naoise explained. All of the intellectual property is in the design, and they are using environmentally friendly materials. Regarding the designs, there are special patented features unique to the system.

“All of our materials are environmentally friendly and we won’t have that problem of dumping toxic materials into landfills. We want to highlight that aspect and push the idea for people to try to develop PV recycling.”

In April 2021, the National Renewable Energy Laboratory (NREL) shared the analysis from a study that a team of NREL researchers has been doing. That study was on how to manage retiring PV modules in support of the laboratory’s vision for a circular economy for energy materials. The research looked at laws and literature on the topic and also conducted interviews with solar industry stakeholders, regulators, and policymakers.

This led to the publication of a series of NREL technical reports that narrow down options and opportunities for PV equipment reuse and recycling. The article NREL published noted that currently there’s little incentive for the private industry to invest in PV recycling, repair, or reuse due to current market conditions and regulatory barriers. You can read more about that here.

In the final report, which you can read here, the researchers noted that the projected volume of decommissioned PV modules in the US alone presented end-of-life management concerns but also material recovery and secondary market opportunities.

Solarflux CTO John Fangman also added that the current trend in product development is the circular economy. He added that several electronics companies are looking at what percentage of the process is recyclable.

“In our case, I would say more than 90%.”

Naoise feels that this is a concern for the industry as a whole even though Solarflux doesn’t have the issue.

Next Step For Solarflux

The next step, Naoise said, was to develop consumer interest in the FOCUS parabolic dish. The next big goal is to raise capital while reducing costs.

“We want to move from making prototypes to making actual products that people can buy at a reasonable price. We have a plan for that and the next big step is to kick off that process and get to the point where we can supply these at high volume and low cost.”

Paris’ popular bike share program has a big sticky finger problem

Paris' popular bike share program has a big sticky finger problem

Paris’ bike-share system, Vélib has long been considered one of the shining success stories of urban micromobility. With a massive fleet of over 20,000 pedal and electric-assist bicycles around Paris, the service has helped millions of residents and tourists get around the City of Light without needing a car or scooter. But lately, a growing problem is threatening to knock the wheels off this urban mobility marvel: theft and joyriding.

According to city officials and the service operator, more than 600 Vélib bikes are now going missing every single week. That’s over 30 bikes a day simply vanishing from the system – some stolen outright, others taken on “joy rides” and never returned.

“At the moment we’re missing 3,000 bikes,” explained Sylvain Raifaud, head of the Agemob company that currently operates the Velib system. That’s nearly 15% of over 20,000 Vélib bikes across Paris.

The sticky-fingered culprits aren’t necessarily professional thieves or organized crime rings. Instead, they’re often regular users who treat the shared bikes like disposable toys.

The city estimates that many people have figured out how to pry the bikes out of the system’s parking docks, unlocking one for a casual cruise and then ditching it somewhere far from a docking station.

Once pried free, the bikes are technically usable for the next 24 hours until their automatic locking feature kicks in. At that point, the bikes are often simply abandoned. Some end up in alleyways. Others get tossed in rivers. A few just disappear completely.

And since the bikes are intended to be parked at their many docking stations around the city, they don’t have GPS chips, further complicating recovery of “liberated” bikes.

The issue started small but has grown into more than an inconvenience – it’s beginning to undermine the entire purpose of the service. With bikes going missing at such a high rate, many Vélib docking stations are left empty, especially during rush hours.

Riders looking for a quick commute or a convenient hop across town are increasingly finding themselves without available bikes, or having to walk long distances to find a functioning one.

That kind of unreliability chips away at user confidence and threatens to drive potential riders back into cars, cabs, or other less sustainable forms of transport at a time when Paris has already made great strides to dramatically reduce car usage in the city.

The losses are financially painful, too. Replacing stolen or vandalized bikes isn’t cheap, and the resources spent on tracking down missing equipment or reinforcing anti-theft measures are stretching thin. Vélib has faced theft and vandalism issues before, especially during its early years, but this latest surge has officials sounding the alarm with renewed urgency.

Officials acknowledge that there’s no easy fix. Paris, like many cities with bike-share systems, walks a fine line between accessibility and accountability. Part of what makes Vélib so successful is its ease of use and widespread availability. But those same features make it vulnerable to misuse – especially when enforcement is limited and the consequences for abuse are minimal.

The timing of the problem is especially unfortunate. In recent years, Paris has seen impressive results in reducing car traffic, expanding bike lanes, and promoting cycling as a key part of its sustainable transport strategy. Vélib is a cornerstone of that plan. But if the system becomes too unreliable, it risks losing the very people it was designed to serve.

Meanwhile, as Parisians increasingly find themselves staring at empty docks, the challenge for the city and Vélib will be to restore confidence in the system without making it harder to use. That means striking the right balance between freedom and responsibility, between open access and protection against abuse.

In a city where cycling is supposed to be the future of mobility, losing thousands of bikes to joyriders and sticky fingers isn’t just frustrating; it’s unsustainable.

CNBC Daily Open: Elon Musk, founder of companies and political parties

U.S. President Donald Trump and Elon Musk attend a press event in the Oval Office of the White House in Washington, D.C., U.S., May 30, 2025.

When they lose a significant other, most men do indeed become a “TRAIN WRECK.” Then they pick up the pieces of their lives and start living again — paying attention to their personal grooming, hitting the gym and discovering new hobbies.

What does the world’s richest man do? He starts a political party.

Last weekend, as the United States celebrated its independence from the British in 1776, Elon Musk enshrined his sovereignty from U.S. President Donald Trump by establishing the creatively named “American Party.”

Few details have been revealed, but Musk said the party will focus on “just 2 or 3 Senate seats and 8 to 10 House districts,” and will have legislative discussions “with both parties” — referring to the U.S. Democratic and Republican Parties.

It might be easier to realize Musk’s dream of colonizing Mars than to bridge the political aisle in the U.S. government today.

To be fair, some thought appeared to be behind the move. Musk decided to form the party after holding a poll on X in which 65.4% of respondents voted in favor.

Folks, here’s direct democracy — and the powerful post-separation motivation — in action.
