episode description
This episode looks at a biofuel crop that grows on Indian wasteland rich in oil; a green slime fuel growing in some flasks in Japan; and a device for converting our footsteps and even noise into energy. Meanwhile a Singaporean company is installing systems in which the hot exhausts from air-con systems are used to heat water, and a new company is developing hydrogen-powered bikes. There’s also a high-tech sea-bed generator and the secrets behind getting electricity from cow-poo.
