Bikejus.

Its been a while, but it doesn't mean we haven't been working on it way to much.

We got the light bulb lit weeks ago, but getting the gear ratio and visual display of information all worked out has slowed us down a bit.

We started with the belt to wheel to motor, then moved to wheel/wheel ratio, this? not so good. So we're back to using the belt.

At 90-100 RPM I can generate about 12-16w constantly not bearing any load, once we hook up the DC/AC invertor I can generate about 1-2w.. on a good day.

We've also started working on refining the visual display of the energy output, thats this week's project.

to be continued.

bikejuice..

bike juice

we'll we've been working on bikejuice a lot. Yesterday I managed to blow the invertor, so Marc has another one ordered and on its way. Today we worked on getting the light to work again, moved down to a LED. We are considering doing a LED interface to chart the amount of energy a user generates like the carnival strength game, this was sort of Todds idea but then we really ran with it and have been trying to figrue out where to buy 1w LEDs for less then 4.60 a piece.

its that time of the semester, discouraging time!

sustainable practices has got me . . . discouraged. The brightest and most intelligent people I know are spending the majority of their lives stagnant behind computer screens, typing away. Change is active yet we are idle.

The world is going on without us, and not a single person here is doing a thing about it. we sit, we talk, we sit some more. the pattern is the pattern for a reason.

Cradle to Cradle

I'm not sure I would consider Cradle to Cradle visionary, a lot of it is things that the hippies in Northern California have been thinking about for the last few decades.

Changing the way we design things vs trying to change the general population however is probably our only answer in trying to save this little place we call home. People are selfish by nature and won't change unless they are given a motive (usually in the US, its financial).

Major corporates hold the power here, just like everywhere else. They have the technology available to them to make sustainable products, they have the ability to completely shift consumer demands with the right celebrity endorsements or they have the ability to keep doing what they're doing.

The book also list five steps which basically could of just been listed and saved me from reading the rest of it:
1) elemenate toxins in goods and services
2) make informed decisions (money talks)
3) Do detailed analysis of any product
4) Design around the positive of a product
5) Reinvent constantly, go back and change, update and change all the time.

I think in the big picture, complex problems defy simple solutions. The world can't be cleaned up if everyone sells their cars and start walking. We need to commit to a total 'big picture' solution for our problems. We needs to remember though, that almost all solutions will hurt someone too. What or who we hurt and who or what we fix I think is the hardest part of the problem to solve.

bookreport for Radical Simplicity.

It's Saturday Night. I should be out at the bars I suppose, but instead I'm spending the evening in. I just finished Jim Merkel's book Radical Simplicity: Small Footprints on a Finite Earth.

Its similar to another book I read a few years ago called Your Money or Your Life that teaches people ways to manage their money so they don't live paycheck to paycheck no matter how little the take home pay. Its actually another book I'd highly recommend for anyone who wants to not be married to a job and have a life outside of just earning one.

So Radical Simplicity: Small Footprints on a Finite Earth is somewhat based of these same principles of conserving what you have and still living well. Think of Radical Simplicity: Small Footprints on a Finite Earth like a 12 step programs for the average consumer.

Merkel starts with the basics, so this book is good for someone who has no knowledge of conservation or their impact on this earth. He explains the carbon footprint and the impacts we have in everyday living and how its things you usually read about, hear about on the news, from global warming to electrical shortages and water problems that are the domino affect of those choices we each make. He also sites examples of people who are living sustainably in the US right now (farms from Georgia to Wisconsin).

The bottom line is "there are 28.2 billion acres of productive land on Earth - when divided between six billion people, each person gets a 4.7 acres" Although this is assuming that humans use all of the earth for ourselves (which as 98% of all species are currently extinct, that isn't such a radical notion). I think a better question for him to pose would be instead, "how much of my acres share do I want to share with other animals or even my grandchildren?"

People are selfish by nature and will not change unless they see a benefit in the change for themselves.

I was disappointed that he didn't talk more about population control (too many children) or what a major affect veganism could have, in a positive way, if it was embraced in the mainstream population (for example 20% of greenhouse gas is a product of livestock slaughtering houses or if America alone stopped eating meat it would essentially solve world hunger as there would then be enough land for crops to grow and feed starving nations). I also hoped he would talk more about consumerism and its effect on animal extension and mass starvation. However, there is much much more to be covered then can be covered in 288 pages.

The truth is, coming to terms with your own demise (or your children's or your children's children) isn't all rainbows and sunshine but there are some simple things we can do to make the world a little bit nicer in the mean time.

For my sustainable practices class, I'll be reviewing this book.
