Chinese got this right

Hydrogen cars are great but you also need 'hydrogen' charging stations. I dislike cars because they cause congestion and in places like India (in fact in many cities) traffic is a nightmare.

Mass transit can alleviate traffic congestion. At least all electric vehicles can help reduce the automobile created pollution both gaseous and particulate. Hydrogen is even better as many are thinking of going the 'hydrogen way'. Toyota will be the first to market one in USA in 2015 after their initial success in Japan a year or two ago.

Since that time they have extended the 'hydrogen' product line to home energy needs.

I really believe that addressing mass transit with hydrogen powered vehicles can solve a whole lot of issues.

The Chinese got this right.

Here are some quick facts about the hydrogen powered Chinese tram from an assembly line in Qingdao excerpted from Qingdaonews.com.

• Only hydrogen powered vehicle in the field
• Two years after starting from scratch
• Hydrogen fill up time is like three minutes that gives a run time of 100KM at 70km/hr.
• With existing tram lines once filled can last for 3 round trips
• Reaction temperature in fuel cell is less than 100 deg C and emits only water
• Trams have 60 seats to carry more than 380 passengers

Here is a screen shot from the same source.

The speeds are modest but does it matter if you consider how long it takes to go 3 miles in a car in Mumbai or Bengaluru.
Transitioning from all gas to hybrid was the first step. Going from hybrid to all electric was a great improvement.

Jumping to hydrogen is the best. For countries under development why wait to go through all these steps, invest in hydrogen.
