Why battery-powered vehicles stack up better than hydrogen

Low energy efficiency is already a major problem for petrol and diesel vehicles. Typically, only 20% of the overall well-to-wheel energy is actually used to power these vehicles. The other 80% is lost through oil extraction, refinement, transport, evaporation, and engine heat. This low energy efficiency is the primary reason why fossil fuel vehicles are emissions-intensive, and relatively expensive to run.

Battery technology is becoming more and more important in modern times. Not only do we use batteries in everyday devices like phones and laptops, but they are also used for large scale energy storage to support renewable power generation. On top of that, the electric car is getting more popular by the day. An innovative leap forward in battery technology could, therefore, be a BIG deal.

A quantum computing future is unlikely, due to random hardware errors

A quantum computing future is unlikely, due to random hardware errors

Quantum computing is an amazingly interesting field. Many predict that quantum computers will dominate our future. Nevertheless, there are also some inherent flaws in quantum computer hardware. Subhash Kak predicts that random errors resulting from those flaws might mean that quantum computers will be less useful than we expect them to be..
