Wind turbines were meant to improve the weather, now it seems these things are making it worse. Bear in mind the weather worriers are fretting about changes of a degree or two (apparently an increase of just 1.5°C means instant disaster and pumping it up by 2°C means an irreversible catastrophe).

A prototype jet engine can propel itself without using any fossil fuels, potentially paving the way for carbon-neutral air travel. The device compresses air and ionizes it with microwaves, generating plasma that thrusts it forward, according to research published Tuesday in the journal AIP Advances.
