20 years earlier, in 1970 Congress banned the advertising of cigarettes on television and radio
Solar spray Scientists at Sheffield have made another leap forward in the realms of renewable energy with the development of spray-on, highly efficient solar cells.The researchers have discovered a way to spray perovskite, a promising new solar technology that combines high efficiency with low production costs.Spray painting this material is a new development that means very little is wasted, and can be scaled up to high volume manufacturing, like spraying paint onto a car.There is a lot of excitement around perovskite based photovoltaics," said lead researcher Professor David Lidzey.Perovskite cells now have efficiencies of up to 19 per cent
There have been a number of criticisms of e-cigarettes
