Fourteen Low-Tech Ways to Stay Healthy (Besides Handwashing)
Fourteen Low-Tech Ways to Stay Healthy (Besides Handwashing)
Health is not just an absence of illness. At the very least health includes a well-functioning immune system, our bodies’ first defense against pathogens that cause disease. This includes COVID-19, the coronavirus.
We are all constantly exposed to bacteria, viruses, and parasites even if we wash our hands twenty times a day. If our immune system is working well, it creates a barrier that stops the antigens from entering the body altogether. This is the first line of defense. If this fails, the second line is for the immune system to produce white blood cells, chemicals and proteins that find, attack and destroy the antigens before they can reproduce. If that fails, the immune system destroys the antigens as they multiply. If the antigens are able to multiply a lot you will feel lousy as your body fights the disease in earnest. You will have unpleasant symptoms. A large part of your energy will go towards your immune system’s battle. You will be sick.
I don’t know about you, but I want to stay at defense levels one and two. And this is more than possible, even with the coronavirus. Don’t get me wrong—handwashing and not touching your face does reduce the amount of pathogens that make it to your immunity barrier, but it doesn’t eliminate them entirely unless you live in a special isolation bubble. To be healthy, you also need your immune system functioning robustly. The following suggestions (to do before you become sick) may strike you as common sense, but, to paraphrase Voltaire, in the middle of a pandemic common sense is sometimes not so common.

10-Minute Neighborhoods: The Low-Tech Solution to Almost* Everything
10-Minute Neighborhoods: The Low-Tech Solution to Almost* Everything
What if it were possible to make headway on all these issues with simple changes to our neighborhoods?
What if we could cut our medical costs in half? What if we could give the average American an added five years of healthy life? What if we could cut our energy use, our water use, and our greenhouse gas emissions by more than half while improving our happiness and prosperity? What if we could provide affordable housing for millennials staggering under student loan debt? What if we could help elders age gracefully in a connected community, with their mobility and cognition intact? What if we could create communities where children can experience both safety and independence? What if we could cut in half the cost of essential services provided by cities and towns? What if we could prevent prime farmland from becoming suburbs and McMansions? What if we could create biodiverse greenbelts and wildlife corridors around our towns and cities? What if inside our cities we could create calming tree canopies, community vegetable gardens and open spaces for all to benefit from?
All this can be achieved with 10-minute walkable neighborhoods, neighborhoods where everyone can step out their front door and reach a wide array of goods and services within ten minutes by foot. All it takes is enough density within a half-mile radius of a commercial shopping street to allow the businesses and services there to prosper. We’re not talking Hong Kong or Manhattan density, just 16 or so housing units per acre, which can be easily achieved by allowing again the “Missing Middle” of housing that was so common before World War II. What is the Missing Middle?

Gasoline–Such a Big Bang for the Buck
Gasoline–Such a Big Bang for the Buck
Are you a fan of beheadings? Are you fond of autocratic regimes? Do you want to help those kooky, lovable Koch brothers purchase another member of Congress? Do you yearn to support Saudi Arabia, Iran, Donald Trump, and Vladimir Putin, but it seems so difficult to give them direct, individual donations? Lucky for you, there’s an easy answer! Just buy gasoline!
Yes, it’s that simple. Oil is a worldwide commodity. Any gallon you purchase props up the price as a whole, enriching international oil companies and oil-exporting nations, with a handsome portion trickling to the politicians they’ve bought. (Oops, “support.”) Your money is guaranteed to enable stonings of adulterous women and beheadings of political prisoners, not to mention facilitate juicy environmental damage from oil spills and toxic fracking waste. In fact, you can rest easy knowing that every dollar you spend on gasoline works hard to attack human rights, cripple the environment and enable political corruption. A three-fer!
But there’s more! On a local level, the gasoline you burn has the happy side benefit of inflicting asthma and cancer on the poorest in your region since it’s the poorest who live along freeways and traffic sewers where tailpipe emissions are highest and the rent is cheapest.

| Make them richer and more powerful! It’s easy! |
As a bonus, it’s easy to double the impact of your gasoline purchase by doing your best to make miserable the lives of anyone traveling without a car. With a little persistence, you can force them to get their own car and buy gasoline just like you. So honk at bicyclists as you pass them. Rev your motor loudly to show them who’s boss. Don’t stop for pedestrians in crosswalks.

An Energy Diet for a Healthy Planet–Part II
An Energy Diet for a Healthy Planet–Part II
How do we get to 100 kwh/person/day, and where are we now?
I’ve written before about how efficiency is not the enemy of resiliency and the benefits of going all-electric. In Part I, I mentioned a few ways to cut our energy diet from 230 kwh /person/day to 100 kwh/person/day. I also pointed out that 56 kwh/person/day of our energy consumption is lost as waste heat in thermal generation of electricity. (One of the reasons Denmark is so energy-efficient is that they use cogeneration and district energy systems to turn this waste heat into heat for homes and commercial buildings.)
This means just converting our electrical generation to solar, wind and hydro, which have no heat losses, will give us a big jump in reducing our energy consumption. Solar and wind are also not 100% efficient in turning potential energy into electricity, but the sun shines and the wind blows whether we turn it into kilowatt-hours or not, so there’s no waste. Whereas the coal, natural gas, oil and uranium that turn into unused heat are gone forever, not to mention all the polluting by-products.
These thermal energy losses in electricity generation are part of the reason Wyoming and Montana are such energy guzzlers. Both states burn coal to create electricity, far more than their state consumes. They then export this electricity to other states. However, the heat losses (2/3rds!) involved in this electricity generation are still part of their state’s consumption. This is also a factor in why energy consumption in California, Massachusetts, and Rhode Island is as low as it is. These states import a lot of their electricity but aren’t apportioned the associated waste heat losses because the fuel wasn’t burned in their state. (Note: there’s no point saying you’re importing “green” energy if the state you’re importing it from is burning coal or natural gas to provide for their own electricity needs.)
