Looking ahead to 2050 – Renewable Energy II

Energy comes in different types, electrical, chemical, thermal, nuclear, movement… Each type has its own advantages related to transport, storage and usage. As an example, storing electrical energy is trickier than storing chemical energy. The density we can achieve with storage technologies is way lower for electrical than for chemical energy, …

Looking ahead to 2050 – Renewable Energy I

The advance of technology is making renewable energy economically competitive to fossil fuels. Standard photovoltaic has now an efficiency exceeding 15%, crystalline silicon panels have reached 20% efficiency and in the labs the most advanced solutions have reached 25% (the record has reached in 2016 34.5% efficiency, close to the theoretical …

Eventually … carbon nanotube memory

Carbon nanotubes have been around for awhile and their characteristics have prompted researchers to try using them for storing bits. They can be very densely packed, so supporting huge storage capacity, they are fast and require very little energy.  They seem an ideal replacement of flash memory. The quest for …
