The latest word from NASA is that the microwave space drive developed by Chinese and British teams isn’t impossible. In fact, it works really, really well!

Electric cars have come a long way- but how far have they GONE? Combined, Earth’s EVs have driven almost 2 billion miles, or, enough to drive past Saturn!
A new technology is promising to dramatically reduce the cost of hydrogen fuel production- and, if it works, it may truly be the end for fossil fuels.
The state that tried to make accurate predictions about sea-level rise illegal is at it again, making more bone-headed statements through its academic mouthpiece, NC State University. The latest round of crazy-talk comes courtesy of a study that claims electric drive vehicles (a catch-all term used to cover EVs, hybrids, and plug-in hybrids) don’t reduce […]
In the past, we’ve written about the dangers of harmful emissions from diesels and the clear and present dangers of commuting. We’ve talked about the American Lung Association’s Minnesota division coming out in favor of cleaner-burning fuels, and we’ve talked about the Chinese government threatening to enforce emissions laws with the death penalty. Until now, […]
The journal Science, after much study and review, has confirmed that the controversial method of extracting natural gas from shale rock known as fracking can cause earthquakes.
More awesome corn ethanol news! Researchers at the A*STAR Institute of Chemical and Engineering Sciences in Singapore have developed a process for pulling fuel-cell hydrogen from ethanol that virtually eliminates the harmful carbon emissions of current hydrogen-extraction processes.
What you see here are the inner workings of the Waissi Engine. It’s named for its inventor, Gary Waissi, an engineering professor at Arizona State University who thinks that things like “connecting rods” are silly wastes of reciprocating mass and (therefore) thermal energy moochers.
America’s infrastructure is in bad shape. Our roads are filled with pot holes. Sidewalks are cracked and crumbling. Bridges are literally falling apart. This problem is not going to fix itself… or is it?
Spider-Man ain’t nobody’s sucka, that’s fo sho! Why I’m talking like those guys from Airplane!, I’m not really sure, but it’s probably because I’m too excited to really think straight. See, Tina Casey (over at Gas 2’s sister site, Cleantechnica) just wrote up an article about Spidey’s best toys: web-shooters. “So,” I hear you asking, […]
Photosynthetic green algae have the potential to be small green factories for producing alternative fuels. Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have shown that increasing the microbes’ overall metabolism by feeding them more carbon increases oil production as the organisms continue to grow. Getting microscopic algae to create alternative fuels is […]
We’ve written a number of articles covering hybrid-electric bicycles over the years – and every one of them has a comment by some clown reader that asks about the Copenhagen Wheel. As well they should! Developed by the young brainiacs at MIT, the Copenhagen Wheel is, essentially, a bolt-on item that converts any conventional bicycle […]
My one, and only, claim to fame is that I am probably one of the only green writers in the world who hates the Toyota Prius. For me, the problem was never the car itself, which is in many ways a technological wonder. No, it was the holier-than-thou attitude of many drivers, who acted like […]
Hydrogen fuel cells have quite a bit of potential as an alternative fuel source for quite a number of vehicles (the Mercedes fuel cell bus and the Mia Rox convertible van come to mind), but they’re not exactly cheap to make. This is somewhat problematic. It’s the Reaction That Counts Within a standard fuel cell, […]
It’s not exactly pulling power out of thin air, but scientists at Newcastle University are awfully close. They’re using bascillus stratosphericus – a strain of super-high altitude bacteria – to help create a biofilm that doubles the performance of microbial fuel cells. While that’s still a relatively low amount of power, it would be enough […]
Engineers in the field of microscopic machines (!) have made the world’s smallest steam engine – the steam engine is micrometers wide, the size of a water droplet found in fog. Physicist Clemens Bechinger of the University of Stuttgart said, “The machine is so small that its motion is hindered by microscopic processes which are […]
Hybrid flywheel energy storage got off to a bit of a shaky start in Formula 1 back in 2009, but the technology is gaining ground outside the motorsports arena in production cars, utility companies, and – now – it’s found its way into bicycles! The bike you see here has been rigged up with a […]
John Galt is the engineering/physics/philosophic genius of Ayn Rand’s me-generation-enabling novel, Atlas Shrugged, who was able to usher in a monopolistic utopia by virtue of an electricity-generating MacGuffin which drew usable power from the static electricity in the air. A neat enough idea – but nothing quite as cool as this: electricity from heat. Possible? […]
The beauty of the Maker Faire is to show us that we CAN make it. Want a diesel motorcycle? You can do it. Want to convert your vehicle to electric? Or steam? Go for it, these guys did! Want a suitcase you can cruise through the airport on? If my 10 year old nephew can make one, I’m sure you can too. For the Maker Faire to expand is to revive that pioneer spirit so many Americans have lost. Even the major sponsor, GE, found something fun and unusual to do with solar panels. They had a solar-powered carousel. It could’ve been a bit more Steampunk, though.
Although the original faire in San Mateo is getting too crowded for my tastes, it remains an excellent place to instill children with a passion for creation. It’s teeming with wonderful examples of how science and math can be fun and wild. Despite feeling quite jaded elsewhere, there’s one thing that never fails to fill me with wonder and delight. And that’s a Tesla coil. Even better TWO Tesla coils! But even better than that, they’re alighting on a Faraday cage filled with children! Oh, and just when you thought it couldn’t possibly be any better….
