…But biology happens for the precise reason that utopian nanotech can’t: The world of the ultrasmall is astonishingly violent. The surfaces of objects turn out to be seething frenzies of motion — atoms vibrating thousands of times a second, bonds forming and breaking. This energetic mess is what powers cellular machinery — but it blows apart anything humans engineer to do the same job.

Electric bikes are not for the tiny-hatted bike geeks leaning over racks of $400 carbon fiber wheels at your local bike shop. They’re not even for people who are happily biking to work already. Electric bicycles are for people who would otherwise drive.

Worse: our food system is so dependent on fossil fuels that it’s entirely possible that it takes more oil to make the food that allows a person to walk a mile than would be expended in simply driving that mile.
This isn’t a result I expected when I started playing with the numbers, so it’s an object lesson in why it’s important to do the math.

Good’s editors came up with the idea for this one. It’s an interesting take on the problem of fuel efficiency – we all know smaller, lighter cars and the electrification of the drive train are the ultimate solution, but a certain amount of waste is inevitable. So: how can we recover it?

…Ironically, this eco-motivated change will undo one of our strongest, if accidental, defenses against climate change.

It’s weird that I had to be sitting in a conference room at NCAR to find this out. You would think it would be news! Just goes to show how little even the journalists who cover this beat really understand the consequences of increasing earth’s radiative forcing even just a little.

World Changing Ideas: 20 Ways to Build a Cleaner, Healthier, Smarter World
Scientific American
If you live in California or Arizona and you have a south-facing roof, there is a startup – possibly even startups – who would like to meet you. Their goal is simple: stick solar panels on your roof at no cost (or virtually no cost) to you. Really.

Hurricane Forcing: Can Tropical Cyclones Be Stopped?
Scientific American
The oceanographers I interviewed for this piece were not kind to v1.0 of the Salter Sink as proposed in Salter’s first paper on the subject. They did want to see more research on it, however. I’m beginning to think that Intellectual Ventures’ policy of revealing its new inventions before papers on them have wound their way through peer review is a mistake.

It turns out that removing CO2 from the smokestack of a coal fired power plant and then burying it under ground in a process called Carbon Capture and Sequestration (CCS) is the most costly, least efficient way to interdict carbon before it hits the atmosphere.
