The Trump administration has the tools to slow the momentum Obama started on clean energy. Countering Trump are global market forces and state-level action.
Fusion power, if it works, offers vast amounts of clean energy and almost zero carbon emissions. A new experimental fusion reactor has come online, and it uses a curious twisted stellarator design.
Lightning strikes are powerful – but we haven’t had solid estimates of their energy until now. Researchers turned to the hollow stone tubes they create by vaporizing sand for more precise calculations.
Fusion development takes time. It cannot be developed in miniature and then be simply scaled up. But we must work now, to make it possible to meet humanity’s need for abundant, clean energy.
A closer look into the latest financial numbers of South Africa’s state power utility, Eskom, suggest that it may be in a more vulnerable position than appreciated.
Back in the early 1900s, if you felt a bit sluggish you could reach for a beverage enhanced with radioactive elements to really add some pep to your step. It wouldn’t be a healthy choice, though.
New technologies that can help us to meet climate change targets are struggling to see the light of day. Incentives need to be fixed, and carbon pricing is at the heart of the matter.
