Also in Greencarcongress, next item, is the Honda Civic CNG car that is sold with a free home-fill CNG device. Both the car and cng filling device are on sale now, low cost.


Could someone work out which is best on a well to wheel CO2 emission basis - using natural gas to make hydrogen which fuels the concept car or just burning the natural gas. Obviously, burning the CNG in the engine is very cheap, what extra CO2 does this lead to?

Obvious question.


If you have looked into solar energy as a method for heating your home, panels are usually the first things that come up.

There are, however, other unique methods.

The Solar Heating Aspect You Have Never Heard of Before

The power of the sun is immense. The energy in one day of sunlight is more than the world needs. The problem, of course,

is how does one harness this power. Solar panels represent the obvious solution, but they have their downside. First,

they can be expensive depending upon your energy needs. Second, they do not exactly blend in with the rest of your home.

Passive solar heating represents a panel free method of harnessing the inherent energy found in the sun for heating

purposes. If you come out from a store and open the door of your car in the summer, you understand the concept of passive

solar heating. A wide variety of material absorbs sunlight and radiates the energy back into the air in the form of heat.

Passive solar heating for a home works the same way as the process which overheats your car in the parking lot.
