Need a coffee when you are off the grid?
FYI there is a really a cool device that uses zero electricity to make coffee. However, it does take time and it’s not as hot as you migh think. It could helps you to have a cup anyway, everywhere…
It’s Designer Gun Ho Lee has come up with this concept for a coffee pot which you can set in your window so it can use the sun to brew you a cup.
The system is designed with an LCD display that shows the amount of energy left in the battery and warns when it’s just too low. No word from the designer on how many cups a fully charged battery can prepare, but since the system is based on modern technology we are expecting some decent numbers there.
