Imagine what cart corals at the supermarket would look like if shopping carts didn’t nest together. Imagine what the entryway of the supermarket would look like if shopping baskets didn’t stack. This would be poor spatial planning on the designers part. Next, image what a parking lot could look like if our cars stacked? We all of the sudden will have a plethora of open space, hmmm why didn’t we think of this earlier?

The first innovative step towards stacking cars was the parking structure, where layers of cars could be stacked upon each other. The next innovative step is to actually stack cars up against each other to reduce the absurd amount of space we require for vehicular parking. The concept is a hybrid of car sharing systems, spatial planning, alternative fueling systems, and personal convenience.

Developed by MIT Media Lab students from the Concept Car Design Workshop sponsored by GM, the key behind this concept is the redesign of the wheel and axel. Rather than having a rigid axel, it will actually fold in a way that will allow the car to rotate upwards 90 degrees. In this, the long dimension of the vehicle is perpendicular to the ground while parked. Since each car has the same form and design, they perfectly nest together to reduce surface space consumption. The stackable car will be able to reduce required curbside parking space by about a third to a half. This allows for more sidewalk space, biking lanes, and comfortable city conditions.

Due to the small dimensions, the stacks of cars will be conveniently placed in locations all over the city- where you would normally come out of a building and hail a cab; you can jump in an electric city car and advance to your next desired location. The concept City Car system includes solar paneling on the rooftops of buildings adjacent to the stackable parking depositories. These panels will be the power supply to charge the electric cars while parked.

This car-sharing concept is a solution to the missing link between public transportation and the front door. Often people don’t use public transit due to the time necessary to switch from the subway to the bus to the next bus. Now people can commute into the city, get off the train, jump in a city car, and drive that extra three to ten miles to the office. This is a reasonable solution to a very prevalent problem. Instead of unnecessarily consuming a parking space while in the office all day long, you can use a city car in the morning and evening, while others use it all afternoon; and the convenience of hopping in a city car is what will make this work. In addition, since these cars aren’t personal vehicles and people will be in them on an average of five to thirty minutes, hopefully the new system will encourage people to share rides across town thus influencing our sense of community, status, and ownership.

Kiss & Cathcart, 2020 towerIsn’t it the best thing in the world when you find out that making a decision about your lifestyle is not only the environmentally-friendly decision, but the economical one too?!!! It makes me want to run through the streets with my arms flailing, telling the world that we are going to be ok. Blue collar, green collar, white collar, red collar… we can all save a bit of money by taking a healthy and responsible action for future generations.

Increasingly, homeowners and businesses are getting bank loans and even grants to install solar and wind power systems on the site of their property. The Database of State Incentives for Renewables and Efficiency is a great place for homeowners to start. It is common to now receive an incentive to reduce the cost of these systems from 25 to 40%, depending on location, of course. The state of Oregon now has 50% Business Energy Tax Credit for all renewable project costs. Not only does this incentive make alternative, local power generation an affordable option, but in provides individuals, families, and groups with the possibility of claiming energy independence from the electric grid.

Following is a supreme example of how the business management of renewable energy systems is gaining strength and incentives. The largest investment bank in the U.S., Morgan Stanley, will finance and own the PV systems that are to be installed atop 7 Wal-Mart stores in California. The way this works is that Morgan Stanley signs on as a financing partner of SunPower, the supplier, designer, installer, and maintenance supplier of the systems. Morgan Stanley pays for the system up front and the customer pays for it over a long period of time, as opposed to 100% up front. This means low investment risk and instant availability. Big business is seeing green in dollars returned by investing in alternative energy that makes good business sense to them. Not only is it just good business because it looks good and tops their environmental checklist, but it’s economical. Tiffany’s, for example is expecting a $500,000 annual savings on the 1.3 megawatt solar installation divided between 2 distribution centers in New Jersey.

I am not writing to debate the politics of appreciating solar value, market value due to commercial demand, and increasing utility prices; I’d just simply like you to appreciate that there is a greater demand. According to Solar Buzz, “Over the last 20 years the cost of solar energy systems has come down seven fold…” According to The Economist, “Global investment in renewable power-generation, biofuels and low-carbon technologies rose from $28 billion in 2004 to $72 billion in 2006.” If you think about it fundamentally, it makes sense that there be more value at a cheaper cost to us in something that is renewable. These businesses are not signing the Declaration of Energy Independence (yet), but they are partially acting on the economical incentive present. Even though designing these stores and warehouses to maximize on natural light might be the most energy efficient option, investing in solar to power the devices within this space has to be applauded.
