Yes, it's true. Engineers are working on an idea to construct enormous, inflatable solar chimneys that will use hot rising air to drive turbines and generate electric.
The idea is a variation on Concentrated Solar Power (CSP) or, more precisely, a solar updraft tower but potentially a lot cheaper to construct.

It's ideas like this that, once world leaders finally agree on a global emissions cutting deal, can be rapidly developed to dramatically bring down the cost of renewables and be part of the solution. We have the technology.
