50 years from now - any predictions for scientific advances?
The Sunday Telegraph is 50 years old today & asked a few experts for their vision of the future 50 years. John Zarnecki, professor in space science, predicts that we will have detected life on a handful of planets in other solar systems and will have 2 way radio contact with a few. James Dyson, industrial designer, predicts that photovoltaic technology will become so efficient that paint on roofs will generate enough energy to power an entire building.
I would hope for big improvements in batteries. At the moment, the best batteries give out about 1 kW-hr for each 1 kg of battery weight. But I would expect to see batteries weighing a few kilos storing 500 kW-hr of power in the future, suitable for powering most vehicles hundreds of miles without recharge – so I’m betting for around a 200 times improvement in power for battery weight
What would be your predictions or hopes for scientific advances in the next few decades?
