- Why the Hydrogen Economy doesn’t make sense. “The advantages of hydrogen praised by journalists (non-toxic, burns to water, abundance of hydrogen in the Universe, etc.) are misleading, because the production of hydrogen depends on the availability of energy and water, both of which are increasingly rare and may become political issues, as much as oil and natural gas are today.” For a heated discussion visit the Slashdot thread.
- Seoul Semiconductor has created the brightest LED ever. It also has the highest luminous efficiency, 110lm/W@350mA (by comparison: fluorescent 70lm/W, incandescent 15lm/W).
- Speaking of efficiencies. Our fridge broke a few weeks ago and in the process of troubleshooting it I went to remove a light bulb in the freezer section and burned my finger. Doesn’t putting heat generating light bulbs in a fridge/freezer strike anyone else as a bit antiquated? Tim over at Instructables thought so too, be sure to read the comments though.
- The Sparta Ion – Europe’s number one E-Bike. Nice integrated battery and motor system and they even tap the battery for a built in headlight.
- Next time you check out a new vehicle look for the new window sticker. The EPA is coming out with their new fuel economy ratings. Car makers have responded with a website: Your Mileage will vary, includes explanations on why the stickers will be showing lower mileage and basic tips on how to help improve it. Hey, now would be a GREAT time for automakers to put MPG readouts in all cars and really help everyone understand and improve their efficiency.
“Hey, now would be a GREAT time for automakers to put MPG readouts in all cars and really help everyone understand and improve their efficiency.”
I listened to an interview on the radio recently about “smart meters” for homes (electricity consumption). If I recall, in Ontario homes where these meters were installed, average energy consumption declined by 6%.
That seems to suggest to me that putting fuel economy readouts in cars would have a measurable impact.
Hi Jerry
I saw that hydrogen link as well, someone referred to it in The Oil Drum.
I spend a lot of time reading that site when I am not reading this one.
