Hydrogen Fuel Cells vs Lithium Battery operated Vehicles

Hydrogen versus Lithium, Checkout this interesting comparison

Published

Video: Real Engineering via YouTube

This is an interesting video, well researched and compiled and creates a reasonable argument for Lithium Battery powered vehicles, as a number of commentators have pointed out, there are issues related to the production of the lithium batteries that need to be considered. My feeling is that both Lithium and Hydrogen Fuel Cell Vehicles are both viable options that need to be considered and used where the most appropriate use of the technology suits, ie where Long range travel is required, the Hydrogen option may be the best option, Whereas small range around town may be more suited to the lithium battery fitted vehicles. What I also find interesting is the comments and some of the people quick to condemn and criticize the author of the video, I think that is absolutely NOT COOL.

Car Runs On Air

This Air car could well be an answer to pollution, global warming and commuting, it’s specs are pretty good, and to be honest I can’t see why it would not be so. Their claims are that it will do up to 200 miles, 60 mph and it can apparently be charged in something like 3 minutes… these are all very good and believable numbers, and it could do this with virtually zero emissions, especially if it’s compressed gas comes from using photovoltaic solar cells to power the air compressor.

Car runs on air

This car has been around for about 10 years now, I wonder if the oil companies have stepped in to stop it’s progress.
The car design reminds me a bit of the Citroën 2CV, which was and possibly still is, that ugly little underpowered French car, which strangely enough was quite popular. In defense of the French, the Citroëns as a rule have always been very innovative, but as with most rules, the 2CV I still think was the exception that makes the rule.

I believe that this Air car could well be an answer to pollution, global warming and commuting, it’s specs are pretty good, and to be honest I can’t see why it would not be so.

However, the ‘perpetual motion’ thing is marketing doing what marketing does, make glib, uninformed statements which are ignorant of the laws of physics.
