Wild Green Yonder

Boeing recently announced that it will have a hydrogen plane in the air later this year. The Boeing Fuel Cell Demonstrator Airplane is scheduled to fly at an altitude of about 2,000 feet (610 meters). The plane has a wing span of 16.3 meters (53.5 feet) and can fly at a speed of about 100 kilometers (62 miles) per hour.

The technology is identical to what is used in hydrogen cars such as the Ford HySeries, GM's HydroGen4 and Kia's 4×4 Fuel Cell Electric Vehicle, i.e. tanks holding hydrogen in the form of compressed gas, fuel cells, lithium-ion batteries and electric motors, in the case of this plane a single motor coupled to a conventional propeller.

Just like cars can (and already are) getting their electricity and hydrogen from the solar panels on top of parking lots, planes could similarly be powered from clean energy, such as from solar or wind power facilities in our backyards.

Boeing first announced the electric plane project in November 2001, when it said the first test flights could begin in early 2004. At the time, there was even speculation that the first flight would coincide with the celebrations of the 100th anniversary of the Wright Brothers first powered flight back in December 17th, 2003. Those plans have since been pushed back several times, but it now looks like it is finally going to happen.

Planes like this have the potential to reshape the face of the world. Imagine if we all used personal aircraft instead of cars. We no longer needed any roads, nor large, noisy airports. Instead we could use small airstrips to take off and land, perhaps in our backyards.

Communities without roads constitute a dramatic change in urban design. Houses could be smaller, as there's no need to put cars in garages. Without roads, houses could also be built much closer together - that in itself could reduce travel time. Simple pathways would be sufficient, connecting all such houses with a center comprising of shops, restaurants, medical specialists, lecture theaters, all within walking distance. Imagine the cost savings on cars, roads, bridges, tunnels, airports, railway tracks and railway stations, on gasoline and service stations. People could largely work from home and meet at facilities of the center closeby, resulting in further savings on office buildings and their car parking facilities.

There would also be huge time savings; given an abundance of small landing strips, planes could take us in a more direct line from one place to another, as opposed to the congested road system where cars line up for a multitude of traffic lights. GPS-navigation and radar technology could also result in a spectacular drop in traffic accidents; after all, there is much more space in the (three-dimensional) sky than on the (two-dimensional) ground.

To help such developments take off, we need to tax items that cause greenhouse gas emissions, such as fossil fuel, meat and fertilizers, with the tax proceeds going to local supply of better alternatives, such as solar and wind power, agrichar and vegan-organic food served in restaurants in communities without roads.

Tax the sale of meat!

There are many ethical objections one can have against slaughtering animals and eating them. Vegetarian lifestyles have been around for ages, just like animal rights activists have long and very publicly protested against animals being used in tests of new cosmetics in laboratoria.

Consumption of red meat from cattle, sheep, goats and other ruminants has long been linked to heart disease, colorectal cancer and further diseases.

The link between meat and obesity has only recently received much media attention, with a focus on the fat and sugar content of fast food.

Similarly, environmentalists have long protested against the loss of biodiversity, as rainforests are cleared to make room for cattle or for soy plantations to feed cattle, all to satisfy global demand for meat.

Now meat has also been linked to global warming in various ways. As the impact of global warming starts to bite, many crops are at risk, due to more extreme weather conditions such as floods, drouhts, storms, heavy rain and moisture. It takes a lot of fertile land to put meat on the table, land that could otherwise be used to grow crops top feed the poor and hungry. At the same time, energy suppliers are increasingly looking at using bio-mass as a replacement for fossil fuel, so food is increasingly competing with energy in agriculture.

Finally, animals like cows and pigs release huge amounts of methane gas, which is twenty times more potent than greenhouse gas as carbon dioxide. A recent study led by Anthony McMichael, professor at the National Centre for Epidemiology and Population Health at the Australian National University, Canberra, provides some figures. It points out that 22 per cent of the world's total greenhouse gases emissions come from agriculture, as much as industry and more than what transport emits. Production and transport of livestock and their feed accounts for nearly 80 per cent of these agricultural emissions, through release of gases such as nitro-oxide and carbon dioxide, but mainly in the form of methane. A cow can belch up to 300 pounds of methane per day. The study was published by the Lancet, at:
http://www.thelancet.com/journals/lancet/article/PIIS0140673600025642/abstract

Before you try and find more details, note that the Lancet has an elaborate registration process demanding that you name your medical specialty and probably at somepoint your blood type, so if you prefer to bypass such things, you can try BugMeNot, at:

In conclusion, a tax on the sale of meat therefore makes most sense. We could leave it up to politics to work out how high such a tax should be, but a flat 10% tax on all sales of meat looks like a good start. The tax could be higher the more methane was released, which would go hand in hand with compulsory disclosure on products of the amount of greenhouse gases that was needed to produce and ship them. Once we've got a good system in place that displays how many greenhouse gases were released in production, we could tax accordingly. There could be different tax rates, even a gliding scale proportional to the emissions. This would encourage research into different diets for cows or somehow replacing the methane-producing bacteria inside a cow's gut.

If the proceeds of such a tax merely used to help the poor pay rising prices for food, then little will be achieved for the environment. Instead, the proceeds of such a tax should be used to create communities without roads, where people can have vegetable gardens close to their homes. We should start building such communities without roads on university campuses, designing small houses for staff and students to live around shops and restaurants. Small houses need less heating and air-conditioning. If we leave out roads, garages and other car-parking spaces, they can be built closely together, so anyone can easily walk or bike their way around. That would be more healthy as well!

Anyway, it makes a lot of sense to turn vegetarian, or even better vegan. Even if you didn't have ethical problems with eating meat and if you lacked compassion for the poor and hungry, you still would help the environment by becoming a vegetarian and thus yourself!

Ten Recommendations to deal with global warming

There are many things we can all do to reduce our contributions to global warming. Here are ten things politians can do now to make a difference:

1. Tax energy supply that adds extra heat to global warming and use the money to subsidize energy supply that doesn't.

2. Stop supporting conventional power plants. Don't give them research grants or subsidies. Don't give them regulatory privileges or allow them to monopolize a market. If they go broke under the new regime of taxes, then good riddance. Instead, support renewables such as wind farms, solar power, hydro-electricity and wave power.

3. Sign the Kyoto Treaty and make a firm commitment to reduce emissions by a lot more. Work on a new global Treaty beyond Kyoto, using these ten points as a basis.

4. Support lifestyles that are more environmentally-friendly. Encourage use of the Internet as an alternative to travel and commuting. Encourage homeschooling and working from home. Deregulate taxi services.

5. Ban incandescent light bulbs. Set a date for a national ban. Actively promote a global ban.

6. Support energy that doesn't add extra heat more actively in regulations and government policy. Encourage competition and diversity among suppliers of such energy. Encourage interconnection and overlap of electricity grids, so that households can choose which grid to sell electricity to, if they generate a surplus in their backyard.

7. Plan communities without roads and with footpaths and bikepaths instead. Plan houses close together, around a local center of shops and restaurants. Redesign existing cities so that people have to travel less.

8. Tax the sale of meat and use the money to support vegetarian restaurants, bicycle shops and other environmentally-friendly outlets in communities without roads.

9. Make government act more environmentally responsible. Ask for ideas. Have more staff work from home. Look at ways to offer services over the phone, over the Net, etc.

10. Disclosure. Make that government departments and large companies publicly disclose their emissions of greenhouse gases. Make products display on their packaging the amounts of greenhouse gases needed to produce it.
