The Outlook of Electric Airplanes
Fueling with electricity offers some advantages not available in conventional internal combustion engine vehicles. Because electric motors react quickly, they are very responsive and have very good torque. While electric cars can replace conventional gasoline cars, why do not we replace conventional planes with electric planes for the same advantages?…

Blockchain for EVs
With most talk about blockchain in transportation focused on freight and logistics, I want to explore the potential applications of blockchain for electric vehicles (EVs). To fully understand the implications of blockchain for EVs, let’s look at a brief overview of the blockchain, an engineer’s view if you will, characterizing the blockchain from its application…

Can we really save the climate by turning air into gasoline?
Last week The Atlantic picked up a story about a Canadian company that is reporting significant progress in reducing the costs of direct air capture (DAC) of CO2 from the atmosphere.
