Pedal Power Book

Here is a link to a free pedal power book, including making your own bicycle powered generators:

Low Tech Magazine

Hi, I recommend Low Tech Magazine for reviews of all kinds of proposals for energy alternatives. They do the research and crunch the numbers on how viable these things really are.

It turns out that direct use of the rotary power is great but generating electricity is not so great. Of course they are not costing it out using salvaged alternators from old cars either.

Human-generated electricity is expensive (but batteries moreso).

In round numbers, you can literally crank out about 100W for about 10 hours per day, so a good day's labor is 1 kiloWatt*hour (kWh), and you'd have to pay about $100 in wages for the crank-turner.  (That seems to me like a reasonable amount of energy to expect from a home-size wind turbine, too.)  From the grid, we currently pay about $0.15 (fifteen cents!) for that much energy.

An "AA" alkaline battery, for which we pay $0.50-$1.00, is good for about 1 Watt*hour (or at least $500/kWh). 

My "5 kW" solar array, on a sunny day in December, is putting out about 10 kWh ($1.50), but put out a little more than 30 kWh ($4.50) on a sunny day in June. (Installed cost, with no energy storage, was about $15,000 in 2014, before subsidy incentives.)

Thanks for this

What an amazing book. I now have it as a PDF file on my computer, and will hopefully print it out.





Contraception, Natural - post peak oil

Cooking with wood - adobe ovens, rocket stoves

Only the first Link works

Only the link to the first pdf works. All the other links fail, by returning me to the Green Wizards Introduction page - this seems to be the behaviour whenever a link is non-existent. Can somebody correct the links please or put the files where they are expected. Thanks.

gaiatechnician youtube channel for new alternative sustainable stuff.

This is not really a plug for my youtube channel.  Several of my projects have won prizes and one of them is on wikipedia.  Plese check out for a new pallet garden concept, the lean away greenhouse, dripper (not drip) irrigation, the pulser pump and various videos about windowfarms, solitary bee habitat and solar cooking.  It is aranged in playlists and I think the playlists are by far the best way to access the informatio that you want.

Almost all my stuff is new. You will not find it in any book but it is all real. Some of it is there in more detail under the same username on

Great Fruit Tree Book: Pacific Northwest

If anyone is looking for a great book on how to grow fruit trees in the pacific northwest--from the Bay Area to Vancouver--I just found the best little book: FROM TREE TO TABLE, by Barbara Edwards & Mary Olivea.  Not only does it give you excellent advice on which trees do best in the climates and soils of your area, it helps you figure out how to trouble shoot any problems you're having as they grow.  It discusses everything from pruning & pests to how to preserve or cook your sweet bounty.
