says: "Dean Kamen invented the Segway. He's also made a fortune in medical technology and now thinks he's built a working Stirling Engine - efficient electrical energy from heat. If it's true it's amazing and world changing - the breakthrough we need to face climate change. Even if it's not, he's a fascinating guy."
Now he and his engineers have built and tested a range of Stirling engines suitable for mass production that can be run on anything from jet fuel to cow dung. The one in the boot of the small blue car is designed to extend its range and constantly recharge its batteries to make a new kind of hybrid vehicle: one fit for the roads of the 21st century. A Stirling-electric hybrid, Kamen tells me, can travel farther and more efficiently than conventional electric cars; it generates enough power to run energy-hungry devices such as heaters and defrosters that are essential for drivers who, unlike those he calls the 'tofu heads' of California, must cope with a cold climate; and even using petrol, the engine runs far cleaner than petrol-electric hybrids such as Toyota's Prius.
Dean Kamen: part man, part machine
However, Kamen confesses, his new creation isn't quite finished yet: 'The Stirling engine's not hooked up. Which really pisses me off.'
But it could work?
'It will work,' he says. 'Trust me.'
I had the pleasure of writing the cover feature, on Limor Fried (aka “Ladyada”) and her company, Adafruit, for the latest issue of Make: (Volume 57).

Even though credit cards now feature an EMV chip for securing transactions, they still have to include the magnetic strip for compatibility with older point of sale systems. Because of this, there’s no way for the chip’s new security capabilities to protect against card skimmers in the wild.How do you protect yourself from legacy-technology-induced fraud? […]
As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
