Houses of the Future - A Wish List - Part I

Single family houses have been the main places I have called home. There were a few apartments I lived in between the ages of 19 and 25…and an apartment we rented while we waited for our third house to be vacated so that we could move in; I always thought of the apartments as temporary and that is what they turned out to be. Of all the housing types available, the single family houses come closest to what I want in the future although I’ve been thinking a lot recently about what would make them better. Some of the items are possible now while others will require technological advances. Here’s my wish list:  

  • All external surfaces need to be productive. They need to generate power or grow food. The paint, brick, siding, and shingles we’ve been using for years protected us from the elements but that is not sufficient for a house of the future.
  • External surfaces and structural integrity need to be sufficient for the environment. In areas of high wind, heavy rain or snow, or extreme temperatures - houses need to be built to survive and remain habitable.
  • Plan for older inhabitants. At least one suite and the main core of the house (den, eating area, and kitchen) must be accessible without stairs. The bathroom needs a large shower that is easily entered. Doors need to be wide enough to easily accommodate mobility devices (i.e. wheel chairs, walkers).
  • A gray water system collects ‘slightly’ used water from sinks, showers, bathtubs, dishwashers, and clothes washers and then the water is used in toilets and for watering gardens reducing the water going into the sewer.
  • The driveway and patio - any concrete or asphalt surfaces - need to be pervious pavement so that water soaks through rather than drains away too rapidly. If water drains from roof surfaces, it should be collected and used for gray water purposes. Again - this reduces the water that goes to the sewers.
  • Yards have grass in areas where it is needed recreation (for example, a play area for children). Otherwise - the yard is either in native vegetation that does not need to be mowed/watered or used to grow food (vegetable garden, orchard) mixed with flowers.
  • The inside of the house can be easily reconfigured as the needs of the inhabitants change over time. The number of internal walls is minimized; permanent walls are only built where they are needed for structure, sound proofing or privacy. Screens, storage units or sliders could be used a movable room dividers.
  • Closets include shelves and racks to allow productive use of the space all the way to the ceiling.
  • All rooms have some form of overhead lighting and ceiling fans.
  • Heating and cooling is done to keep the temperature at comfortable levels in rooms that are in use at the time and the system is tunable for a particular person (for example, the room where an older person is located might be warmer in the winter time).
  • Heating and cooling is done in the most efficient way possible for the area. In areas where geothermal (buried pipes) heat pumps are possible, this may be the way to go….or maybe there will be other technologies that will be even better. The classic gas (or heating oil) furnaces and electric air conditioners are not what we should be building in the future.
  • Lighting is on when the room is occupied and it is needed. Otherwise the lighting turns itself off.
  • Window coverings adjust based on temperature and are linked to the heating and cooling system. For example, on a  the window coverings will allow direct sunlight to shine in to warm the inside on a cold day to the temperature preferred by the person in the room.
  • Kitchens need to function well for several people cooking at once.
    • If there is room for a center island, it needs to be counter space - not a stove top.
    • Ovens - microwave and conventional - are combined into one unit.
    • Water for drinking (and ice) is filtered.
    • Over counter cabinets go all the way to the ceiling to maximize storage space.
    • Task lighting is installed under the over-counter cabinets and comes on automatically when needed.
  • At least one wall of each room is a ‘screen’ that displays art or functions as a computer display.
  • Work from home is a growing trend - particularly for workers performing their jobs via computer. The house needs to be adaptable to support a work environment for everyone in the house.
  • Modular construction may be a way to make new technology more accessible at a reasonable cost. The idea of a core of rooms (kitchen, eating, den) with all the utilities connected being built first with modules of rooms that plugged into those utilities is appealing both to allow for 'starter' homes and then enlargement of the house later by the addition of modules.
  • No more items that are merely for ornament like shutters that don't close or dormers that provide no space on the inside. 

I’ll post the coninutation of my wish list tomorrow.

Slow Motion Hummingbirds - Video of hummingbirds at a feeder

Costa Rica's Self-Sustaining Tree House Community - A community of tree houses complete with indoor plumbing and zip lines

Bees in the bush working hard! - Photos of insects coming to a wildflower south of Nairobi (hint: more than bees) from National Geographic

What’s so Great About a World Flight Paths Map? - Comments about a visualization by Michael Markieta (showing the visualization too)

Top 25 Wild Bird Photographs of the Week #43 - My favorite in this batch is the very first one. The bright pink of the flowers and the yellow of the bird really stand out.

Bay Bridge Crossing the Chesapeake Bay

The Bay Bridge (William Preston Lane Jr. Memorial Bridge) crosses the Chesapeake Bay via 2 spans that are over 4 miles long. It is full of hefty metal compared to the newer Ravenel Bridge that I posted about after my trip to South Carolina. What a difference 40 years makes! 

I took pictures from the vantage point of Sandy Point State Park on the western side of the bridge and then as we drove across the bridge going to (east span) and coming back (west span) from Chincoteague National Wildlife Refuge. It was a misty and cool day on the eastward journey. The pictures from Sandy Point (the first three in the slide show), captured the mood of the day. There is still some morning color penetrating the moisture in the air. On the way back, the day was sunny.

Technique to Detect Breast Cancer in Urine Developed - Wouldn’t it be wonderful if this really works and can replace routine mammograms?

Image gallery: frost - From the Weather and Climate page of the Royal Meteorological Society. Use the frame on the left to look at other image galleries. There is also an interesting animation of Hurricane Katrina under ‘Resources’

Cicada Swarmageddon! - Our area of Maryland is on the edge of Brood II of the 17-year cicada which is due to make an appearance this year. We haven’t seen or heard any yet but I enjoyed learning about the less visible parts of the insect’s lifecycle in this video.

Picnicking Through the Ages - We are more likely to use an ice chest and canvas tote rather than a basket….find a picnic table in a park rather than spread a blanket. We still enjoy eating outdoors as we travel. Recently it appears that parks are encouraging people to take home their own trash rather than providing trash cans...a return to pre-park etiquette of picnicking.

First Drug to Significantly Improve Heart Failure Mortality in Over a Decade - Coenzyme Q10….a supplement that is a drug. And other drugs for heart failure depleting the Coenzyme Q10 that the body makes on its own….maybe a feedback loop that, over time, actually made those drugs less helpful to the individual with heart failure.

Little White and the Three Toxins - A new species of mushroom…a new toxin?

Ten Days of Little Celebrations - May 2013

Back in August 2012, I posted about finding something to celebrate each day. It’s an easy thing for me to do and the habit of writing it down reminds me to be grateful for these and a myriad of other things in my life. Here are some ‘little celebrations’ I’ve noted this month:

Peonies at the Lewis Ginter Botanical Garden. The whole garden was special but the peonies were the highlight. See the post here.

Rhododendron at the Norfolk Botanical Garden. Lots of beautiful plants and glass artwork…but the rhododendron were at their best. See the post here.

A balanced diet day that met 90% nutritional requirements from food. I started recording me food intake on cronometer.com and learned very quickly that there was room for improvement. First I got the protein/carbs/fat percentages aligned to the recommendation (when I started, fat was overwhelming carbs too frequently); then I started to improve the percentage of nutritional targets I achieved with food (from the low 80s to low 90s). It has be more of a learning experience than I anticipated - and a very positive one.

New camera. I am thoroughly enjoying my new camera (a Canon PowerShot SX280 HS). See some blog posts about it here and here.

Planting seedlings grown in egg shells. I planted some seedlings started in egg shells that are doing well in pots on the deck. See the gleanings post that gave me the idea.

Lowest weight of the year; highest stock market day of the year. These may seem like unrelated metrics but they are both items I monitor daily. It is a day to celebrate when they both move in the right direction on the same day.

Horseshoe crabs at Sandy Point State Park. The view of the Chesapeake Bay Bridge would have been the highlight for me if the day had not been so misty. Instead I flipped over a horseshoe crab that had stranded itself upside down on the beach and celebrated that is crawled back into the water. I’ll be doing a post about the park in a few days.

Osprey, barn swallows, and immature bald eagle at Blackwater National Wildlife Refuge. I cannot pick which of the three birds I enjoyed spotting more! I’ll have a blog post in a few days.

Blue grosbeak and egrets at Chincoteague National Wildlife Refuge. The surprise of seeing a purple grosbeak in the wild for the first time was quite a high point…but then the myriad egrets and their antics took the stage. Pictures will be posted in a few days.

Finding a surprise iris in my garden. I thought I had moved all the iris bulbs from the back garden that had gotten too shady to the front garden where they would get more sun. It worked - they are booming in profusely in their new flower bed but I found on lone flower in the back flower bed….a missed bulb that managed to bloom even in the shade. I celebrated its survival.

Adventures with a New Camera Part 1

I am experimenting with my new camera - a Canon PowerShot SX280 HS . So far - the experiment has included only the simplest aspects of the camera: using the zoom of my own position to frame the picture want. So far I am impressed with the results.

2013 05 IMG_5960.jpg

At first I expected that the camera would not focus for the close-up flower shots that I have enjoyed capturing with my older camera (a Canon PowerShot SD4500 IS)….but I was pleasantly surprised that it did so well with the azaleas at the left. I like the way the flowers pop out of the image with the light glowing through their petals.

2013 05 asian image.jpg

How well would the camera capture ripples in water? I experimented with an Asian-type composition shown below. I like the results but will have to try again on a sunny day to see what the camera automation will handle the glare from water in brighter light.

The big improvement with the new camera was touted to be the ability to capture clear images with the zoom feature. Plants are easy since they are still (if the breezy does not interfere). The dandelion and fiddlehead were good tests. I liked the clarity of both images - and that I didn’t have to expose myself to the poison ivy that surrounded the dandelion!

Images of birds and small animals will be easier to capture with this camera. It will take some practice but the automatic settings are quite good. My initial attempts with some birds and a squirrel are below. The challenge will be to frame the animals in their natural setting - avoiding things like the twig in front of the squirrel’s nose in the image below.

I am going to enjoy this camera! Maybe I’ll gradually use some of the fancy settings too.

3 Free eBooks - May 2013

The Internet has a growing number of online books…and many of them are free. This is my monthly post highlighting 3 that I have enjoyed most this past month.

National Research Council. Global Trends 2030: Alternative Worlds. December 2012. Available in several downloadable forms here. A new global trends report is published every 4 years following the US Presidential election. It is intended to provide a framework for thinking about possible futures and their implications. Is our future going to be characterized by stalled engines, fusion, gini-out-of-the-bottle or nonstate world…or some combination?

Paxton, Sir Joseph. Paxton’s Magazine of Botany and Register of Flowering Plants. London: W.S. Orr and Co. 1834-1849. More than 10 volumes available on the Internet Archive here. I can’t resist including at least one eBook with botanical prints. Many of the images are quite recognizable - like the azalea at right.

Dobson, George; Grove, Henry M; Stewart, Hugh; Haenen, F. de. Russia. London, A. and C. Black. 1913. Available from the Internet Archive here. Look at this book for the pictures and realize that it is about that time just before World War I when everything was breaking…no one fathomed just how bad it was going to be or what would be built afterwards on the rubble.

Charleston Tea Plantation

In late April, I visited the Charleston Tea Plantation - enjoying the beverage samples in the gift shop and the tour on a trolley around the place. I enjoyed the sign that pointed out how far this tea plantation is from the major tea production centers of the world. Growing tea requires warm and moist conditions - not found in the US in many places. Wadmalaw Island is one of the few places where is it possible. The plantation may be a little out of the way from other attractions around Charleston but it is a pleasant drive on a road bordered with large trees….and it is a unique experience.

The location and the flatness of this plantation make it usual for a tea plantation. The flatness here allows for automation that is not possible in mountainous terrain where tea is grown elsewhere. The one-of-a-kind machine shown below clips the new growth from the top of the bushes and collects the cuttings as it rolls down the rows of tea bushes 8-10 times a season.

The processing of the leaves into black, oolong and green tea is done on the plantation too. The factory can be viewed from two sides via big windows and filmed vignettes explain how the equipment operates to produce tea.

A factoid: Once tea bushes are established, they grow so densely that few weeds grow.

I took pictures from Patriots Point - from the parking lot,

from deck of the USS Yorktown air craft carrier

and from the picnic area -

and even Charles Towne Landing.

I was not driving so was able take pictures from the front passenger seat as we drove across. The slide show below are my favorites.

Stairs to the Roof

In Arizona, the flat roofs sometimes have stairs leading up to them. They can be used as a place to observe the sunset or sunrise…or the stars. It is a different way of thinking about that top part of the house. Lining the staircase with potted plants….putting a gate at the top to keep a toddler contained...it is an appealing difference from the roofs I see in Maryland.

And why shouldn’t we make roofs more than just a surface covered with shingles or other material to seal the house from the sky. What about collecting the water from the roofs into rain gardens rather than sending it to the sewers? Why don’t all roofs have some power generation function?

In the future - a roof that is only a roof should be the exception.
