That and of course the extra cost makes such a home unaffordable for the vast majority of the worlds citizens. A nice idea though

And the homes will probably be subsidised for the wealthy that can afford them in the first place I shouldn't laugh really, it is a cool idea but it did make me chuckle.

One needs to think beyond the moment. About 50 years ago color TVs were not affordable for many families. Now just about everyone can afford a color TV. Most new technology initially falls outside the affordability of the masses.

This is because it takes research and investment to arrive at a new piece of technology. Thus these costs have to be recovered to allow further research and investment to then refine the technology and improve its performance.

This in turn then allows lower costs to be achieved by offering more performance for the dollar to the consumer which helps stimulate consumer demand and hence volume production and hence overall profitability and hence profit and economies of scale etc... and this feeds back into the lower cost loop.

Once a plant is producing widgets at full capacity, its operating most cost efficiently. Now say in 5 years time a new more efficient widget maker comes along and the first widget maker is still at full capacity. This could form the justification to buy the second widget maker, produce widgets at lower cost and hence offer consumers cheaper widgets, which by the way have also been refined in their technology and operational efficiency. etc... etc.. and the cycle just keeps going where widget performance evolves as does the widget making equipment. And the beat goes on

Most PCs today, would have cost a fortune 50 years ago and taken up whole rooms and used up lots of power. Even 5 years ago if you were able to buy a PC offering the performance and memory capacity of today's PCs, they would have been out of the cost range of most people.

It can take several years for technology to evolve, improve in performance and hence sales and volume of production to rise, to help facilitate lower costs both to the manufacturers and then consumers.

Just because something seems expensive today, does not mean it will be as expensive in several years time. Usually the opposite occurs with price falling over time for a given level of technology. If the idea is good offering real community benefits, costs will generally fall over time, so long as the supply of raw materials and labour remain at a constant rate relative to consumer demand.


Give it time lad, give it time.

There's a pretty cool house design called Enertia that doesn't have any heating or cooling devices.

Quote:
solid Energy-Engineered(tm) wood walls replace siding, framing, insulation, and paneling. An air flow and access channel, or Envelope, runs around the building, just inside the walls - creating a miniature biosphere. Here solar heated air circulates, pumping and boosting geothermal energy from beneath the house, storing it in the massive wood walls. Thermal inertia causes the house to "float" between the cycles of night and day, and even between the seasons.

Yea thats a great concept the "Heat Pump House".

Gordon Brown's promise to make new homes "zero carbon" by 2016 is unlikely to be met because of "deeply embedded" failings in modern house-building methods, says a Government report.

The seven-year study tested "eco-homes" built to insulation standards beyond those of the latest regulations and discovered heat losses that designers did not expect.

The sooner they see limitations, the sooner they can try to iron out the bugs. It was a bold ask and it's a talking point which is great.
