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.
