Hot coffee can also charge mobile phones.

Modern people have a growing sense of environmental protection, so there are more and more related products that can use green energy to generate electricity, and Epiphany onE Puck, which raises money on KICKSTARTER, is one of them. The Epiphany onE Puck looks like a high-tech metal coaster. It doesn't need any external power and can charge the phone with the heat generated by a cup of hot coffee. In particular, Epiphany onE Puck can not only convert heat to generate electricity, but also use the low temperature of a cup of cold cola to convert it into electricity.

The interesting thing about Epiphany onE Puck is its two-sided design. The red side can be used to convert heat into electricity. Just put in a cup of hot coffee and wait for the light to come on. Then you can charge your phone and tablet through the USB cable. But the design team also thought that most people will not only drink hot coffee forever, but also want to drink cold drinks when the weather is hot, so all you have to do is turn the Epiphany onE Puck over and put the cold cola or beer on the blue side, and you can also turn the low temperature into electricity to recharge.

Although the design team has not yet announced how efficient Epiphany onE Puck can convert energy into electricity, you have no way of knowing how much hot coffee or cold beer you will need to tie up your phone to recharge. But seriously, the two-in-one concept of coaster and charger, which makes full use of green energy, is really good. Epiphany onE Puck's goal is to raise US $100, 000, and if all goes well, mass production is not expected until 2014. If you are interested in it, you can sponsor it at KICKSTARTER for US $115, or about NT $3404.
