SolarisKit, a Scottish B-Corp have developed a flat packed solar water heater that can be assembled in 20 mins and can heat water to 60 degrees Celsius. The kit uses a solar coil to absorb heat from the sun and heat water that passes through the coil. The kit can be daisy-chained to create a home solar water heating system, or as a standalone water heater for camping or garden pools.
Researchers from Meiji University in Japan have invented electric chopsticks that trick your mouth into tasting salt without it being present in the food you are eating! The chopsticks send the electrical waveform that activates ions in salty and umami components into the user's mouth to change their taste perception of the food. The hope is using these chopsticks can reduce national salt intake by 20%.
Engineers in Japan have achieved a data transmission speed of 319 TBps across 3000km, using a new fibre optic transmission mechanism that splits data into different wavelengths and transmit it simultaneously, amplified along the way. The new cables are the same size as existing fibre cables, making them easier to install within existing infrastructure.
