Google sends satellite carrying TPU into space; launch costs key

Google has sent a demonstration satellite carrying its TPU chip into space for the first time to test an orbital data centre concept. The Planet Labs-built satellite will check whether the TPU can operate in space, including continuous 1 kW power supply, chip cooling and errors while running models. The company’s longer-term plan envisions 81 satellites flying in formation for parallel computing, but it says the concept requires significantly lower launch costs.

Battery charged at 10-metre depth as \'underwater solar\' moves closer to reality

Researchers have developed perovskite solar cells that can generate electricity at depths of about 10 metres by improving durability and tuning light absorption to underwater wavelengths. The team tested a wide-bandgap device in the lab and in the South China Sea, reporting 34.71 percent efficiency under simulated 10-metre conditions and 16.79 percent under standard sunlight. A sealed module showed little degradation after about 1,160 hours underwater, with a T80 life estimated at 48,094 hours. Field tests charged a battery at 2, 6 and 10 metres.
