Follow These Easy Moving Tips

Hi Every One,
How are you all? Moving from one home to another always puts a lot on one's plate. Nevertheless, moving does not have to be a bad experience. Here are a few things to keep in mind that may make your move a little smoother.

- Consider how you will provide the necessary means to actually move your belongings. Decide if you will hire a moving crew, rent a moving truck, or use a portable storage unit, such as SMARTBOX. Have your reservation made as far in advance as possible.

Solar charging an electric vehicle (motorcycle)

Here's some deep physics analysis into the requirements for using solar panels to charge an electric motorcycle or other EV.

http://blog.dotphys.net/2009/05/solar-powered-motorcycle-possible/

Some vehicle makers might add solar panels as a way to woo people into thinking the car is extra cool. Such as Fisk'ers karma which has solar panels on the roof ... but the roof is so small it only provides a modest amount of power, enough to run the in-cabin stuff like air conditioning.

Break though at lithium batteries - longer service life - lower production costs

Just got to publish a break though in lithium battery technology

Ober 30 years of service life,
Electrolyte is exchangeable.
BMS gives maybe every 10 years a message: please exchange the electrolyte.

Extrem fast charging possible

TED Talks Bill Gross: Great ideas for finding new energy

This talk just came in through the TED Podcast and I thought it was immensely interesting. Bill Gross, the presenter, is the founder of Idealab (linked below) which seems to be a kind of high tech incubator company. It appears from Idealab's website that they spun up a company named Stirling Cycles, which was later sold to Infinia Technology (also linked below). This appears to be unrelated to Stirling Energy Systems who is building some kind of large installation in the Mojave desert.

The idea he talks about is an intelligently designed heat capturing system that feeds heat into a stirling engine to produce electricity.

How many miles / gallon are you getting with your electric bicycle?

Last weekend I attended a talk by the CEO of Coulomb Technologies. They're making charging stations meant to be deployed around a city for electric vehicle drivers to use. He had an extremely interesting presentation, and it gave me the topics for a series of blog posts.

This first Equating "fuel" efficiency between electric, hybrid, and gasoline vehicles tries to answer the efficiency of an EV over a gas vehicle. For instance Tesla claims its Roadster gets 190 miles/gallon equivalent efficiency.

Solar car completes 1st ever round-the-world trip

POZNAN, Poland – The first solar-powered car to travel around the world ended its journey at the U.N. climate talks Thursday, arriving with the message that clean technologies are available now to stop global warming.

The small two-seater, hauling a trailer of solar cells and carrying chief U.N. climate official Yvo de Boer, glided up to a building in Poznan, Poland, where delegates from some 190 nations are working toward a new treaty to control climate change.

Phoenix is Dying

Email I just received:

Phoenix Mission Status Report October 29, 2008

PASADENA, Calif. -- NASA's Phoenix Mars Lander entered safe mode late yesterday in response to a low-power fault brought on by deteriorating weather conditions. While engineers anticipated that a fault could occur due to the diminishing power supply, the lander also unexpectedly switched to the "B" side of its redundant electronics and shut down one of its two batteries.

Introductory "lecture" on Petroleum science and Peak Oil

Last month I attended the Association for the Study of Peak Oil USA conference in Sacramento. I'm finally getting around to posting the audio I recorded at the conference and thought one of them would be interesting to this crowd. Everything is being posted through my podcast, the home page for the podcast is here: http://www.7gen.com/technosanity

Technosanity #14: Petroleum & Peal Oil 101 was given by Dr. Ken Verosub, a geology professor at U.C. Davis. He gave a high level overview of the science behind how this planet produces oil, the model behind the peak oil claims, and a few simplistic calculations related to near term production of oil and the looming crunch in oil demand versus oil production.

Destructive patterns in technology

A while back I had this idea come to me.. one that seems so right on the more I think about it.

It's about the pattern our society follows in destructive use of our resources. The destructive pattern is to take something, use it, destroy it by using it, and throw away the shards that remain from the destruction.

Peak oil program from Australian TV (Four Corners program)

I found this following program on the bittorrent sites but it appears you can watch it online. It's a really good rundown on peak oil issues and dangers.
