The device converts wave motion into electricity using off-the-shelf materials, challenging the assumption that marine energy research requires massive budgets.
The generator costs around ten euros, built from PVC pipe and 3D-printed components.
It converts the kinetic energy of ocean waves into usable electricity.
The project stands in stark contrast to the billions industry spends on marine energy R&D.
Two rare dehydrated potatoes survived half a millennium at a coastal Peruvian archaeological site, giving researchers a direct window into Inca food systems.
Two freeze-dried potatoes roughly 500 years old were found at a Peruvian Inca site.
Chuño, the Andean freeze-drying technique, was central to Inca food storage and distribution.
The coastal desert's arid climate preserved the organic material across five centuries.
The American company known for 3D-printed rockets will develop the "Aeolus" spacecraft under an official NASA contract, entering the race to Mars alongside SpaceX.
A new theoretical study suggests that when a massive star collapses, quantum physics may prevent a black hole from forming — and spawn a new universe instead.
A massive star's collapse could produce a baby universe rather than a black hole, according to a new theoretical model.
Extreme quantum physics in the stellar core may prevent singularity formation and redirect collapse energy.
The hypothesis is strictly theoretical and cannot be confirmed by direct astronomical observation.
