Malcolm's house at Oyster Cove

Wave House 3D model on Google's 3dwarehouse

2012-01-14T10:47:00.005+11:00

I've started designing a sustainable house based on a light-weight, insulated outer skin, high thermal mass internal walls made from unprocessed rock and a wave-shaped roof to take advantage of passive solar heating and cooling.

You can download a model of Wave House into your Sketchup world from the Intresto collection on Google's 3dwarehouse. Go to http://sketchup.google.com/3dwarehouse/ and search for "wave house" or "Intresto".

There's more information about the Wave House design on my other blog: http://malbertswavehouse.wordpress.com/

Rocksolver Investor Presentation - 1st November 2011 - Sydney

2011-10-18T11:03:00.003+11:00

On Tuesday 1st November 2011 at 5:30pm at the NSW Government’s Trade and Investment Centre on level 47 of the MLC Centre in Sydney the Rocksolver team and I will be presenting Rocksolver as an investment opportunity.

To attend this event please register here http://rocksolver20111101.eventbrite.com/

Malcolm Lambert introduces Rocksolver on ABC TV New Inventors - 6th April 2011

2011-04-03T20:18:00.004+10:00

The dry stone wall above features on New Inventors and was built by following a plan automatically generated by the Rocksolver software application. Rocksolver is currently undergoing prototype testing in preparation for its first commercial release later in 2011.

If you'd like to know more about the Rocksolver technology or about Intresto as an investment opportunity please leave your contact details at http://www.intresto.com.au/contact-us

More 3D virtual rocks

2010-12-05T11:57:00.004+11:00

The rocks in the image above are all virtual 3d models and are a selection of over 60 models available for download from the Intresto collection on Google’s 3dwarehouse (http://sketchup.google.com/3dwarehouse).

All the models were derived from real rocks so they have a natural look even when scaled to the size of a small stone or large boulder. The models were generated from a 3D laser scanner or from the point cloud derived from the Photosynth photogrammetry application. The models were processed as triangular meshes using MeshLab and then textures applied using Sketchup.

The models can be imported for free directly into Sketchup, used in your landscaping or hardscaping projects or exported as a Collada dae file then imported into Meshlab. From MeshLab they can be saved in a range of 3D formats such as VRML, obj, ply or stl then imported into CAD or 3D animation, graphics and rendering applications such as Blender. Have fun.

My new website - intresto.com.au

2010-05-28T17:57:00.002+10:00

It's the same name as the old website but it's been redesigned:

Rocksolver builds a wall

2010-05-28T10:05:00.004+10:00

Even before structural stability criteria have been explicitly programmed into Rocksolver it has built a stable structure. The photo shows Rocksolver's automatically generated design and the small desk-top structure built from real rocks following Rocksolver's plan. Rocksolver is using a 2D optimisation algorithm which would suit many applications such as retaining walls where stone masons already select prism-shaped rock. Stone masons mostly use a mental 2D algorithm to build a variety of structures from prism-shaped rocks because that's a lot easier than the mental 3D manipulations required to build with a random selection of rocks. Already Rocksolver has the capability to use 3D algorithms and build with random irregular shapes. Results from 3D testing will be published here and at intresto.com.au as they come to hand.

Could be a world first

2010-05-05T13:05:00.002+10:00

The image on the left is the result of running a Rocksolver simulation using data corresponding to 5 real rocks. The right-hand image is the real structure built by following the packing plan devised by Rocksolver. This could be the first time a new structure has been built from irregular objects following instructions from a computer program. It's possible some old structures have been re-built following the output from archaeological reconstruction software. The software required to simulate the rebuilding of an old structure is quite different to that required to simulate the building of a new structure so I'm happy to say it's a first.
The packing plan in the image came from my first desk-top simulation, even before the packing algorithm parameters had been optimised so things will only get better from here on.

3D virtual rocks on Google's Sketchup

2010-04-28T22:39:00.005+10:00

These 3D virtual rocks come from real rocks which were scanned. The virtual rock mesh was reduced to just a few hundred faces, imported into Sketchup then uploaded to Google's 3dwarehouse where they are freely available for download from the Intresto collection.

Intresto

2007-06-08T16:25:00.000+10:00

Intresto Pty Ltd is a company I have just started to help me attract government funding (governments will fund companies but not individuals) so I can keep going with the research and development. Intresto is from Intelligent Rearrangement of Stone, something people have been doing for thousands of years, I'm just throwing a computer into the mix. Have a look at www.intresto.com.au (formerly www.rocksolver.com).

The ant survives

2006-09-15T18:26:00.000+10:00

In the high resolution animation it's possible to see the ant scurry over the hills in the distance after it nearly gets squashed by the first rock. I modelled the ant on the Bull Ants living under the front windows of the house I built at Oyster Cove.

My invention

2006-09-15T18:09:00.000+10:00

My invention, the "rocksolver" (see www.intresto.com.au), uses a computer to fit together irregular polyhedra, each of which approximates the shape of a rock used to build a wall. When the computer finds a rock to fit into the wall it outputs instructions to the builder as to the rock's position and orientation. The 3D shape of the rocks can be acquired by using a laser scanner or by digital photgraphy.
Have a look at www.intresto.com.au (formerly www.rocksolver.com) for more information.

gone to a good home

2006-04-15T18:32:00.000+10:00

Fiat 1100, 1961. The last time it was running was in 1990. At that time it was in good order until the motor suddenly stopped working. It might simply be a broken part in the distributor. Since 1990 it's been sitting outside, mostly under a tarp. The subframe is sound but there is some rust on the body and I suppose some of the parts have deteriorated or seized up over the years. It would be a project to get it going again but the basic parts are all there and it comes with a full set of workshop manuals.

May 2006 - I sold my house

2006-04-06T09:51:00.000+10:00

The photo shows bluestone paving around the front doors. The doors are old double swinging doors from a pub and I've set them into solid Celery-top pine poles.

my house

2006-04-03T15:27:00.000+10:00

The northern part (left side of the photo) of the house is a hexagon and contains the kitchen, dining, lounge and study areas in an open-plan type of space. The hexagon has lots of windows in the northern half and a wood fire in the middle, making it light and airy during summer and warm and cozy in winter. On the right is the bedroom. Behind the bedroom is the toilet and bathroom. Separating the northern and southern parts of the house is a glassed-in vestibule area. There is also a separate studio.
My house is at Oyster Cove, 35km south of Hobart.

lounge

2006-04-03T15:08:00.000+10:00

The lounge space.

dining

2006-04-03T15:00:00.000+10:00

The dining room...well, it's in the same space as the kitchen, lounge and study. The kitchen and study are separated from each other by an internal mudbrick wall. In the middle of the hexagonal room is "Warmbrite", the wood fire.

kitchen

2006-04-03T14:52:00.000+10:00

The sink is set into a Celery-top bench and the cupboard framework is Celery-top with Tas-oak and corrugated iron doors.

The glass ceiling.

bathroom

2006-04-03T14:41:00.000+10:00

The wall separating the bathroom from the bedroom is a curving wall made out of corrugated iron. It's got the same green-colour on both sides, with insulation in between. The bathroom is a work in progress. It has a shower, hand basin and washing machine. It has enough room for a bath but I'd have to evict the washing machine.

paving

2006-04-03T14:37:00.000+10:00

I paved outside the other front doors using local bluestone.

the view

2006-04-03T14:33:00.000+10:00

Bruny Island in the distance.

looking towards the SE

2006-04-03T14:21:00.000+10:00

Around the house is a wide area of mown grass which is a fire break in the event of a bush fire. In the 21 years I've owned the property it has never been threatenned by fire.

Bracken is my friend

2006-04-03T09:40:00.000+10:00

This view is looking towards the west. The bush in the background and the hills behind the bush protect the property from the worst of the weather that sometimes hammers Tasmania from the west and south. In the foreground is lots of bracken fern which has an undeserved bad reputation. I've found the bracken a very useful plant nursery. Young trees are protected by the bracken from summer sun, winter frost, competing grass and browsing animals. Once the tree is higher than the bracken it starts to out-compete the bracken and then other understory plants can regenerate.

Hobart to Oyster Cove

2006-04-03T09:27:00.000+10:00

Between Bruny Island and the mainland is the Dentrecasteaux Channel. The region on the mainland-side of the water is simply known as The Channel and is widely recognised as being one of the nicest regions in Tasmania. Because of the Channel's popularity is has become busy recently but Oyster Cove has remained a quiet locality, partly because there is no township or industry (apart from farming) and the highway is over a kilometre from the water.

The house is the light-coloured area visible in the upper-left of the property. Thanks Tom for the photo.

The empire.

house plan

2006-04-02T20:12:00.000+10:00

Large windows in the NE, N and NW facets of the hexagon collect sunlight throughout the day. During winter nights solar energy is released by the slow-combustion fire. The trees on my property use solar energy to extract carbon from the atmosphere and convert it into wood, then I chop up the wood and burn it to release that energy. I grow more trees than I chop for fire wood so my property is a carbon sink.

climate

2006-04-02T20:08:00.000+10:00

This is what the weather does at Oyster Cove....on average.

weather deficiency

2006-04-02T20:02:00.000+10:00

Lightning display over Bruny Island. One of the few things about Tassie I don't like; there are not enough thunder storms.

aurora

2006-04-02T19:56:00.000+10:00

The Aurora Australis over my house. I usually see an aurora 2 or 3 times a year, sometimes they pulsate like someone is playing with the light switch and occasionally the whole southern sky is glowing red.

water

2006-04-02T19:47:00.000+10:00

The 5,000 litre tank on the left collects rain water from the shed and carport and the 12,000l tank on the right collects water from the house. About once a month I use the petrol-driven pump to pump from either tank to a 7,000l header tank which provides gravity-fed water to the house. The pump can also take water from any of the 3 tanks to feed the white fire hose in the event of a bush fire. All tanks are Aquaplate. The lowest the water level has ever been is half capacity.

the dam

2006-04-02T19:42:00.000+10:00

Down the north-east corner of my property is the dam. I don't use the water so it's a great place for the wildlife and it's never even looked like going dry. In the background is my house.

botanica

2006-04-01T18:00:00.000+11:00

Since 1985 the property has mostly transformed itself from a grassy paddock to regenerated bushland. During that time I've taken a photo of every native plant that has regenerated itself.

the wall and the invention

2006-04-01T17:51:00.000+11:00

On top of the concrete slab is a low rock wall made from a light-coloured sandstone. Before I bought the land in 1985 the sandstone had already been blasted to level the building site. On top of the rock wall are mudbricks made from the local soil. The rocks in the foreground are bluestone from the local Red Hill quarry.

Whilst fitting the sandstone blocks together I thought about a method where several rocks first pass through some sort of 3D scanner then a computer fits them together and outputs instructions to the builder as to the position and orientation of each rock. I'm in the process of taking out patents on the method. I've called it RockSolver. Have a look at www.rocksolver.com

photo record of the building process

2006-04-01T17:42:00.000+11:00

I've got an album with photos showing all sorts of building methods during the house-building process. It also contains photos of pipes and cables in trenches before they were covered over so I know where not to dig in future.

tactile timber

2006-04-01T17:33:00.000+11:00

Most of the timber furniture and fittings, like this Huon Pine table and the parquetry floor, have been oiled using a hard burnishing oil based on tung oil. I did this so that when I touch the wood I'm actually touching wood. When timber has been coated with some sort of varnish or polyurithane then what you touch is plastic. Also, I prefer the look of wood rather than the look of plastic-coated wood....but that's just me.

Storage

2006-04-01T17:28:00.000+11:00

The inside of my studio/shed where I lived from 1992 to 1998 whilst building the house.

Lawn mower

2006-04-01T17:20:00.000+11:00

I mow the lawn once a year, late December or early January. Then for the rest of the year the grass is kept under control by teams of Bennett's Wallabies (one pictured here), Pademelons, Potoroos and Native Hens.

Oyster Cove

2006-03-31T08:58:00.000+11:00

This is the Cove; about 15 minutes walk, along quiet country roads, from my house.

Sunny afternoon

2006-03-30T20:53:00.000+11:00

This is my house, as viewed from the clothes-line (looking towards the east).
On the right is the bedroom. There is also a separate studio (see other photos).
In the far background is Bruny Island.
