  • T-GenX Solar Energy T-Shirt: Eco-Friendly and Innovative Design

    T-GenX Solar Energy T-Shirt: Eco-Friendly and Innovative Design

    Key Takeaways

    1. The T-GenX is an innovative T-shirt that generates electricity using thermoelectric technology, currently in the crowdfunding phase on Kickstarter, posing financial risks for backers.

    2. The T-shirt can produce up to 2 watts of power under ideal conditions with a temperature difference of 20 Kelvin, sufficient for charging small devices like smartwatches and headphones.

    3. Achieving the necessary temperature difference is challenging in warm or humid conditions, limiting the T-shirt’s effectiveness for power generation.

    4. The manufacturer suggests the T-GenX is more suitable for colder environments, raising questions about its practicality for everyday use.

    5. Backers can purchase the T-GenX for $89, but alternative options like regular power banks with solar panels may offer better value.


    First of all, it’s essential to point out that the T-GenX is an ambitious item from a lesser-known brand, and it’s currently in the crowdfunding phase on Kickstarter. This situation means that supporters may encounter significant financial risks and could end up losing their investment, while the technology might also face some challenges.

    T-Shirt Technology

    Moving on, the T-GenX is a T-shirt designed to produce electricity. It achieves this by utilizing heat, or more specifically, a temperature difference. While thermoelectric Peltier elements are a well-known and reliable technology, the T-GenX incorporates flexible modules instead.

    As per the producer, a setup with either 4 or 10 modules can generate 5 volts and currents between 50 to 100 or 300 to 400 mAh. This could, in theory, charge smaller gadgets like smartwatches, headphones, or even a power bank. However, the limitations are clear, as this peak output of 2 watts can only be reached with a temperature difference of 20 Kelvin.

    Real-World Limitations

    In situations where ambient temperatures exceed 68 degrees Fahrenheit, especially in the humid summer months, achieving this temperature difference seems unlikely. Plus, wearing a sweater would naturally lower the temperature difference, thus decreasing the power output. So, even in the best-case scenario, 2 watts of power would lead to very slow charging.

    The manufacturer subtly acknowledges this limitation by mentioning that the T-shirt is best suited for colder areas or caves. Whether anyone would actually want to wear a short-sleeved T-shirt in such conditions is another topic altogether. Backers can secure a T-GenX for a pledge of $89, plus shipping, with the first deliveries set to be made in September. At that price, buyers might also consider picking up a regular power bank with a small solar panel on Amazon.

  • Swiss Watch Prices May Rise Due to Increased Tariffs

    Swiss Watch Prices May Rise Due to Increased Tariffs

    Key Takeaways

    1. Swiss businesses, especially watchmakers, are preparing for significant financial impacts due to a 39% tariff imposed by the Trump administration on their goods.
    2. Major companies like The Swatch Group and Richemont may need to raise product prices, potentially leading to consumer inflation and affecting their financial results.
    3. Market reactions show a 22% drop in shares of Watches of Switzerland and an 18% decline in Swiss watch exports compared to the previous year.
    4. Switzerland exported $61 billion worth of goods to the US in 2024, making it the 17th largest trading partner, but the trade balance is unfavorable for the US.
    5. The Swiss government is seeking a negotiated resolution to the tariffs, having expressed disappointment, as the US is Switzerland’s largest trading partner.


    Swiss businesses across various industries are getting ready for the financial consequences of the new tariffs that the Trump administration has put in place. Watch makers and exporters in Switzerland are bracing for potential price increases and changes in demand due to the steep 39% tariff (up from 10% as of April) imposed on their goods, marking one of the highest tariffs currently enforced.

    Impact on Major Companies

    These tariffs are set to take effect next week, stirring up concerns among firms like The Swatch Group (which owns brands such as Omega, Tissot, Breguet, and Blancpain) and Richemont (which includes Vacheron Constantin, Jaeger-LeCoultre, Panerai) as well as retailers like Watches of Switzerland (which sells Rolex and Patek Philippe). As a result, these companies might have to raise their product prices, which could lead to increased consumer inflation and affect their financial outcomes. Nonetheless, manufacturers have stated that they are trying to minimize the impact on their customers.

    Current Market Reactions

    The consequences of these tariffs are already becoming apparent. According to Bloomberg, the shares of Watches of Switzerland have dropped by 22% over the past year. In addition, the Financial Times has noted a decline of 18% in Swiss watch exports compared to the previous year.

    In 2024, Switzerland exported $61 billion worth of goods to the US, ranking it as the 17th largest trading partner. However, the trade balance is unfavorable for the US, which has made it a target in the administration’s goal of “securing fair, balanced, and reciprocal trade relationships,” as stated by the White House.

    Swiss Government’s Response

    The Swiss government has expressed disappointment over this decision but has indicated that they are pursuing a negotiated resolution, even though previous discussions have not led to an agreement. This tariff could have serious repercussions for Switzerland, as the US is its largest trading partner. In May alone, exports from Switzerland fell by 39%, impacting sectors like pharmaceuticals, watch manufacturing, chocolate, and coffee, among others.

  • Circular Ring 2: Extra Costs for Blood Pressure and Sugar Analysis

    Circular Ring 2: Extra Costs for Blood Pressure and Sugar Analysis

    Key Takeaways

    1. Circular Ring 2 launched on Kickstarter, with the first 1,000 units shipped after a successful campaign.
    2. The ring is priced at $249, making it more affordable than the Oura Gen 4, which costs $349.
    3. It offers advanced features like ECG, blood pressure, and estimated blood sugar level measurements.
    4. Blood pressure and blood sugar features now require payment through microtransactions or “Circular Coins.”
    5. Circular Ring 2’s core features remain free, and users can earn Circular Coins through regular use of the ring.


    Circular Ring 2 was funded through Kickstarter in the spring, and last week, the first 1,000 units were shipped to supporters. The ring was priced starting at $249 during the campaign, making it much more affordable compared to the Oura Gen 4, which retails for $349 on Amazon.

    Advanced Features

    The main aim was to surpass rival products by offering more analytics: the ring claims to perform electrocardiograms (ECG) and assess blood pressure and blood sugar levels. Blood pressure is measured using a heart rate sensor and ECG, much like the Samsung Galaxy Watch8, which likely means it will need calibration with a standard measuring device. The blood sugar level is merely “estimated,” so the information it gathers can only serve as a rough guideline.

    Subscription Concerns

    Although Circular Ring 2 was marketed during the Kickstarter campaign as not needing a subscription, the two standout features—blood pressure and blood sugar measurements—are now behind a paywall. To access these features, users must engage in microtransactions or spend “Circular Coins.”

    As these features are set to be available only after an update anticipated at the end of the year, it’s still uncertain how much they will cost. Backers expressed their frustrations in the Kickstarter comments, noting that Circular Ring 2 was originally promoted without any ongoing fees. In response, Circular emphasized in a statement that the 13 “core features” of the ring remain free, and users can also “earn” Circular Coins by using the ring without any additional spending.
