Data Power and Counter-power with Chinese Characteristics
, 2022 AbstractHow to make sense of China as a global data superpower? This chapter attempts to offer new insights that are historicised and holistic, considering China’s internal conflicts and its relations with the external world. It starts by outlining and debunking two myths about China, fetishising it as either dystopia or utopia.

Structure and Characteristics of the Cordless Power Station.
Journal of the Magnetics Society of Japan, 1993 The "Cordless Power Station" is a power supply system which does not use cords. The system makes use of electromagnetic induction generated with coils. Such systems will have uses such as supplying power to portable household electrical appliances or charging the batteries of circuits.
