Mgr. Mirko Riha Inventor
The Solar and Compressed Air Managed HoseholdTM provides safety, patent issued. The unconventional techniques, ensures better living and during natural disasters, reduction of the risks. Articles at www.mirkoriha.com.
The photo above shows the basic house model with roof solar panels. Situated to the right, low level, is the energy compartment
Alternatively, the energy compartment is under the house’s roof, close to the solar panels.
Data produced by Energex Ltd. confirmed that the electricity produced by rooftop solar panels is strongest several hours before householddemand for power peaks. The compressed air managed household air compressor, harvest the solar energy throughout the day. The energy stored in battery of air tanks, is used twenty four hours per day, to actuate components of household.
The following are described conceptions for specified environment.
More people are injured and killed, during bushfires and floods, in the open than
in houses. To keep house safe from bushfire requires property’s defences.
Can a house be removed into safety? The ingenuity of man is incredible. A record was broken close to Los Angeles, by National Geographic. A house of 4.8 x 4.8 x 5.4 metres was lifted by 300 balloons, each 900mm in diameter, filled with helium. Result of National Geographic team of scientists, engineers and workers. The ultra-light house weighted 4000 kg, plus four people 300 kg, was lifted to 3000 meters and flew one hour.
Regrettably, most of our family houses weight over 40 000 kg. This makes the balloon idea as well as lifting by a helicopter out of question. The most powerful helicopter Mil V-12 record lift was 40 205 kilograms.
During the years, the writer emphasized the advantages of the Solar and Compressed Air Managed Household. After designing and building house extension, he became familiar with buildings. Bushfire protection of houses built in wooded area remains the best option. During natural catastrophes, there is a good chance to protect and save family houses
This is based on a model of a house built in wooded areas. There are several defences to make a house safe from bushfire. The model house is protected by fireproof textile blanket. In one piece, the fireproof blanket would be cumbersome. The model house shows fireproof blanket segments, joined by Hi-Temp Velcro. Another defence is fireproof foam spread over the house. The house managed by compressed air has the means for spreading the fireproof foam, by compressed air available. Once the bushfire passed, the fireproof foam is scrubbed by means of compressed air and the fireproof blanket is detached from Velcro and rolled back to its ground storage.
The above left photo shows the fireproof blanket lifted half-way from its ground storage. The upper windows of the house are not covered. The residents can observe the direction of the bushfire, oncoming towards their house. If bushfire, is approaching their house, the fireproof blanket is pulled over and covers the house, as shown in the picture to the right. The fireproof blanket is in sections, joined by Hi Temp Velcro, or other joining means. The fireproof blanket covering the expensive solar panels may not be enough to be heat protected. With the compressed air available, fireproof foam is sprayed over the solar panels. The cool clean air from air tanks are available.
Floods, Earthquakes and Tsunami waves not breaking
The writer, years back, designed a novel hydrodynamic hull attached to a family inflatable ski boat. It was a small capacity outboard required, with low fuel consumption. It proved to be powerful and very economical. This knowledge led to the hydro dynamically shaped, floating house.
Design pending, the model of a house, built for flood and earthquake, tsunami’s areas is unconventionally built. It has a horizontal, suspension platform deeply and secularly anchored to the ground, in a way of a suspension bridge. Many tsunamis waves do not break, as they hit the land. Tsunami waves grow in height as they approach land, flooding low lying areas, rebounding off the hill and causing further damage as they recede back to the sea.
Due to changing hydrodynamic pressure, the suspended platform of the floating house rides out the tsunami. The changing power of the hydrodynamic forces has little effect on the suspension platform. The suspension platform, due to the excessive forces temporary remains out of alignment but has the capacity to straighten back to its original position. On the boundary of the dwelling the horizontal suspension platform are firmly attached a number of vertical anticorrosive, extensile rods, or tubular rods. The number of rods, or tubular rods depends on the house size, minimal four are required. The house, at its periphery has corresponding cylinder tubes, linear guide for the rods, or tubular rods. The anticorrosive extensile rods or tubular rods are linear guided by the house’s cylinder tubes, permitting floating more than 10 metres above ground.
Very strong, deep anchoring is necessary. As an alternative a central single solid extensible tubular rod is fixed to the horizontal suspension platform. A corresponding central cylinder tube is extended from the house’s base up to the roof. To the base of such a house a floating material such as Styrofoam is installed, causing the house to float, during flood and tsunami.
During a flood when the house is floating, the extensile rods, or tubular rods slide within the cylinder tubes, permitting the house to float up and down. During earthquakes the quake tremors are reduced, due to the resilient suspension platform and the buoyancy foam. Archimedes, the scientist of the third century BC, discovered his Principle: A submerged body is subject to a buoyancy force equal to the weight of the fluid displaced by the body.
Left picture shows house in a container filled with 1/3 of water. The floating house, with the silver tinged horizontal platform. The water container of the picture to the right is filled with water to the rim and the house is floating, exposing the horizontal platform and the vertical rod, or tubular rods.
Tsunami waves do break wave’s turbulence hitting land
Tsunamis have a rich history, many people were killed, cities and towns destroyed. The 2004 devastating Indian Ocean tsunami killed hundred thousands of people.
The latest event occurred in 2011 in Japan. The coastline in Japan is lined with concrete seawalls to protect the country against high waves, typhoons and tsunamis. From a report shown on TV, the seawalls offered little protection from the tsunami. Close to the earthquake the tsunami that followed washed over the seawalls that were supposed to protect the area, including the nuclear power plant. Sea water disabled the diesel generators, which were crucial for maintaining the cooling system of the reactors, during shutdown. The Japanese earthquake-resistant, fortified hi-rise buildings, during the quake rocked violently, however not collapsed reducing the number of casualties. After the catastrophe infrastructure will be reconsidered and redesigned.
Many tsunami waves don’t break, as they hit the land. Most of damage done is due to surge sea waters, flooding low-lying areas and the resulting rebound-recede. Breaking waves require additional defence.
Tsunami destroyed many family houses. Areas of the house most effected where the walls and the shallow angled or flat roofs. The high wave speed detaches the house from foundation and crushes it into a ruin. History often demonstrates the power of the nature causing calamities, despite the best human developed defences.
The Japanese, earthquake-resistant, heavily grounded, high-rise buildings, coped with tsunami, reducing the number of calamities. A family house, which is relatively light, must have hydrodynamic shape, floating capacity and a very good anchorage.
The previously described house constructed for flood, earthquake and tsunami waves, has the solar panels at the top of the house. There is no defence when tsunami waves break, crushing the house’s flat roof and the walls. For this case a different tsunami house roof is required.
The model shows the roof of a house in a form of an umbrella for the case if tsunami waves break over. The registered design conical roof, umbrella shaped, foldable, has a pointed top end. The turbulent tsunami breaking waves is diverted by the conical, pointy roof, towards the ground, by-passing the house.
The umbrella shaped roof is built from strong materials, such as stainless steel, aluminium, Kevlar or other materials. The semi-cylindrically shaped walls are on both sides of the house, one facing the sea and the other one the hills. The semi-cylindrical shapes are enforcing laminar flow, around the house.
The house suspension platform constructions are built to contain the forces in motion. During the Japanese tsunami the boats, shown on TV, were torn from their anchorage. A described floating house, solidly anchored, will not move from its anchorage and has a good chance to remain undamaged. The model above shows the house walls of a semi cylindrical shape in order to diverge the destructive seas. The semi cylindrical walls enforcing the laminar flow around it will protect the house. With stored water, or a desalination unit, food, clean air and power supplied to the house.
Natural catastrophes kill many people with huge financial losses. The above proposal is presented to reduce these losses.
