Passive House Platform

Browsing through Leonardo Energy, I found a post pointing to a very interesting webcast on a European standard geared toward ultra-low energy building, referred to as passive houses.

The term passive house refers to a specific construction standard for residential buildings with good comfort conditions during winter and summer, without traditional heating systems and without active cooling. Typically this includes very good insulation levels, very good airtightness of the building, whilst a good indoor air quality is guaranteed by a mechanical ventilation system with highly efficient heat recovery.

MDI Compressed Air Technology (C.A.T) led me (1, 2) to a short article on what could prove to be a promising technology: a vehicle powered by compressed air, also available as dual energy hybrid engine.

Being a syndicated article formatted for print and broadcast, there were no links to further references, so I researched the subject a bit deeper and found a slew of information on this clever French-built innovation (though the concept isn’t new).

Here are a few of the links I found interesting:

The reasons and challenges involved are obvious, but I hope MDI finds an effective way to muffle the vehicle’s rather loud audible output. Zero or reduced emissions are definitely a very respectable and timely achievement, but noise/sound pollution can also be quite a scourge, particularly in urban areas.

All in all, I can picture a great future for this technology, especially in the Third-World in the short term, which has so far been more opened than wealthier countries to fossil fuel alternatives.
