The study, by engineers at the University of Sheffield, is the first to prove conclusively that contaminants can enter pipes through leaks and be transported through the pipe network.

The pressure in mains water pipes usually forces water out through leaks, preventing anything else from getting in. But when there is a significant pressure drop in a damaged section of pipe, water surrounding the pipe can be sucked in through the hole. 

Even though there is a long way to go before electric vehicles are accepted by all motorists, there is no doubt that the Kansas City Power and Light company is putting Kansas City on the map. The company announced very interesting and very ambitious plans to install 1001 electric vehicle charging stations across the area which it serves. This is certainly a very interesting development at a time when advances in electric vehicle battery technology are hitting the headlines but consumers are still concerned about range anxiety.

Will this move make a difference?

As one executive put it “if you install the charging stations they will come” which just about sums it up. The $20 million “clean charging network” will consist of 1001 charging stations which will be able to charge two cars at the time. Not only will this encourage more electric vehicles in the region but it will also greatly help with charging at busy times of the day. The simple fact is that until somebody actually took the plunge and decided to install electric vehicle charging stations we would always be at the beck and call of electric vehicle battery technology.

Siete mil millones de sueños. Un planeta. Consúmase con cuidado. Ese es el tema del Día Mundial del Medio Ambiente de este año (celebrado el 05 de junio!)

Establecido por la Asamblea General de las Naciones Unidas en 1972, el Día Mundial del Medio Ambiente (DMMA) ayuda a crear conciencia para proteger la naturaleza y fomentar la sensibilización en todo el mundo y la acción para la protección del medio ambiente.

Seven Billion Dreams. One Planet. Consume with Care. That is the theme of this year's World Environment Day – celebrated today, June 5th! Established by the United Nations General Assembly in 1972, World Environmental Day (WED) helps raise awareness to protect nature and encourage worldwide awareness and action for environmental protection.

First of all we have to say that the vast majority of US state authorities are continuing with their current electric vehicle financial incentives, with many actually increasing the amount of funds available, but some states are struggling. Connecticut, Georgia, and Illinois are just three states in the US where electric vehicle financial incentives are being tapered down. Whether or not they are reintroduced in the future remains to be seen but budgets need to be balanced.

Is this a reflection of the technology?

It would be easy to say that we are yet again looking at a false dawn for the electric vehicle sector but this would be wrong. There has been enormous government and corporate investment in the industry and it is inconceivable to even suggest it will fade away into the background as it has done before. The simple fact is that many states across the US, and governments around the world, are struggling to balance their books during the current tight economic environment and schemes such as financial incentives to switch to electric vehicles are feeling the brunt.
