Molecular Heat pump for electric cars

Heat pump for electric car would make it run farther
By Itza Montforte Noguez, web writer.

USA, Pacific Northwet National Laboratory.
This laboratory is working on nanotechnology that would extend the range of electric cars by allowing them to heat and cool the passenger cabins with a new type of heat pump. The final goal is to create electric cars that are more affordable to operate.

This work is inspired by the final goal of having 1 millions electric cares on the road by the year 2015. The problem with current electric vehicles, powered entirely by electricity is that they are limited by the power-storage capacity of their lithium-ion bateries. The design proposed is for a new type of heat pump that would require far less power to heat and cool a car, extending battery charce and range.

The design is based on metallic organic frameworks (MOFs) which  are formed out of metal ions bound to organic compounds, nanotechnology improvements. MOFs are porous and can be calibrated to cause various chemical elemts to bind with them in controlled ways to that they can control de condensation and evaporation of the refrigeant, heating or cooling air delivered to the car's interior.

The researcher wanto to creat a new, 5-pound molecular heat pump, that sice of a 2-liter bottle that would handle both heating and cooling and allow the cars to travel longer distances before they need to be plugged in again.
