It doesn’t get greener than this
It makes not difference if the cars are green or not, they are still not as green as they could be, the same can go for many other types of transport, but there is one form of transportation that is totally free, eco friendly and now can even produce electricity into the bargain.
So what is this all powerful means of transport? Walking, yes walking is free, keeps you fit and healthy, costs virtually nothing and now according to research will be able to produce electricity. This concept is based on heel strike which is the point of contact of your heel while walking. It has been estimated that by installing a heel strike power generation system at Victoria Station on the London Underground, the heel strikes of the 34,000 people using the station every hour could power 6,500 light bulbs, neat idea!
