I’m willing to sacrifice a clean shave for the good of the planet. I have to if I want to be zero waste. All the options on the market involve disposable razors, the kind you throw-out after a week. It’s a minor thing but every bit counts when you’re trying to be zero waste. At a certain point all you have left to cut-out are the little things.
I’ve considered investing in a straight blade, barbershop style. One that I could sharpen myself and get the closest shave of my life. It sounds manly and tough, like teaching myself about knives will earn a boy scout badge. But I grew up in a peace-loving, near-hippy family and so I’m not used to any sort of weapon.
And my first alternative was already lying around in the bathroom – an electric shaver. I cut my hair with it and decided to try a shave with it. It’s not exactly the closest shave but it does the job. And I collect all the shavings for the compost. They disappear immediately in there, not like an ear of corn which take forever to disintegrate.
The only problem with this method is that it uses electricity, but I’m okay with that. I see the world moving towards all-electricity devices running on renewable energy. And since the power company allows me to pay more for renewable energy, it feels ok.
But I still look forward to earning that man badge and become the first person I know to shave with a real blade.
Men, have you ever shaved with a real blade?
Ladies, do you have a way to avoid using a disposable razor?
The city of Milton Keynes will replace the diesel buses on one route with eight electric buses that will use wireless charging. The route currently transports more than 775,000 passengers a year over a total of 450,000 miles. Electrification is expected to remove about 500 tons of tailpipe CO2 emissions per year, and cut running costs by between £12,000 and £15,000 per year.
The busses will charge when parked over a primary coil in the ground. In 10-minutes the coil can send enough energy to the secondary coil in the bus that it can complete its route. The plan is to place the primary coils at the beginning and ending locations for the bus route and coordinate charging with bus driver breaks.
If all goes well this technology could be “real contender in the future of public transport.”

Not only do electric cars threaten all those gas stations on every corner, but also the auto-mechanics and car parts stores:
Mechanic worries that electric-car brakes will ruin his business
Joe Ferrer says that brakes are easily 35 to 40 percent of his total business. Replacing rotors, calipers, and pads keeps his shop humming.
But on hybrids, brake jobs aren’t needed every 15,000 miles as they are on conventional cars–more like 45,000 miles, he says.
Those regenerative braking systems reduce the impact when braking and extend the life of the brake pads.
Of course, this isn’t the only thing that will change, Jiffy Lube will also be hurt. Electric vehicles (EV’s) get rid of nearly all the liquid lube in cars, so that means no more oil changes.
What is going to happen to all that land currently used for gas stations, Jiffy Lubes, and mechanics shops?
This story is a bit old (October 2011), but in light of Chip Yates project to create the first all-electric transatlantic flight, is worth reading about:
NASA has awarded the largest prize in aviation history, created to inspire the development of more fuel-efficient aircraft and spark the start of a new electric airplane industry. The technologies demonstrated by the CAFE Green Flight Challenge, sponsored by Google, competitors may end up in general aviation aircraft, spawning new jobs and new industries for the 21st century.
The first place prize of $1.35 million was awarded to team Pipistrel-USA.com of State College, Pa. The second place prize of $120,000 went to team eGenius, of Ramona, Calif.
“NASA congratulates Pipistrel-USA.com for proving that ultra-efficient aviation is within our grasp,” said Joe Parrish, NASA’s acting chief technologist at NASA Headquarters in Washington. “Today we’ve shown that electric aircraft have moved beyond science fiction and are now in the realm of practice.”
The winning aircraft had to fly 200 miles in less than two hours and use less than one gallon of fuel per occupant, or the equivalent in electricity. The first and second place teams, which were both electric-powered, achieved twice the fuel efficiency requirement of the competition, meaning they flew 200 miles using just over a half-gallon of fuel equivalent per passenger.
“Two years ago the thought of flying 200 miles at 100 mph in an electric aircraft was pure science fiction,” said Jack W. Langelaan, team leader of Team Pipistrel-USA.com. “Now, we are all looking forward to the future of electric aviation.”

From the Fresh Energy blog and a good reminder that most experts have trouble thinking exponentially.
- In 2000, the International Energy Agency (IEA) published its World Energy Outlook, predicting that non-hydro renewable energy would comprise 3 percent of global energy by 2020. That benchmark was reached in 2008.
- In 2000, IEA projected that there would be 30 gigawatts of wind power worldwide by 2010, but the estimate was off by a factor of 7. Wind power produced 200 gigawatts in 2010, an investment of approximately $400 billion.
- In 1999, the U.S. Department of Energy estimated that total U.S. wind power capacity could reach 10 gigawatts by 2010. The country reached that amount in 2006 and quadrupled between 2006 and 2010.
- In 2000, the European Wind Energy Association predicted Europe would have 50 gigawatts of wind by 2010 and boosted that estimate to 75 two years later. Actually, 84 gigawatts of wind power were feeding into the European electric grid by 2012.
- In 2000, IEA estimated that China would have 2 gigwatts of wind power installed by 2010. China reached 45 gigawatts by the end of 2010. The IEA projected that China wind power in 2020 would be 3.7 gigawatts, but most projections now exceed 150 gigawatts, or 40 times more.
- In 2000, total installed global photovoltaic solar capacity was 1.5 gigawatts, and most of it was off-the-grid, like solar on NASA satellites or on cabins in the mountains or woods.
- In 2002, a top industry analyst predicted an additional 1 gigawatt annual market by 2010. The annual market in 2010 was 17 times that at 17 gigawatts.
- In 1996, the World Bank estimated 0.5 gigwatts of solar photovoltaic in China by 2020, but China reached almost double that mark—900 megawatts by 2010.
