The PowerLeap: Harnessing Human Energy With Floor Tiles
Our friend Ruben Miller sent us an email on an alternative energy concept him and his wife submitted to the Metropolis’ Next Generation 2007 competition and we think it’s pretty cool. While the idea of harnessing human energy has been around for awhile, this one actually seems feasible. From the article,
“Imagine a nightclub where dancers generate the venue’s electricity just from the impact of their steps. With Redmond’s innovative flooring system, this vision of a human-powered energy source may be close to a reality. The floor tiles, cast in durable concrete and recycled glass, are fitted with piezoelectric brass-reinforced ceramic plates covered in nickel electrodes. With the impact of each footstep, a metal pointer inside the tile compresses the ceramic plate, generating an electric impulse. The resulting voltage activates four LED lights, visible through the glass surface, allowing energy-generating participants to see the power of their steps.”
This type of technology is intended for high-traffic areas; sidewalks, playgrounds, school hallways, etc. Obviously, you could do away with the LED lights and incorporate the idea into flooring that makes the whole thing less obvious. We love the concept, however, and hope Elizabeth and Ruben keep pushing to make it a reality.
Solar Powered Wireless Means Backcountry Internet For Eco Geeks.
So you’ve got the backwoods hobbit house, the flexible solar panel for charging your laptop, and a wind-powered chimney for everything else. Problem is, you’re three acres away from the nearest wireless signal and you’d love to actually get some work done. Up until now, there weren’t many options — besides some homebrew kits — for making it all come together. Thankfully, a company called Meraki has introduced a $549 router/repeater kit powered by solar and capable of forming a WiFi mesh network with other units. Not only does this thing stand up to rain, snow, sleet, wind, hail, and direct sunlight, but it also optionally allows you to charge for people to access your network — including the ability to run ads and other clever marketing.
Right now San Francisco is currently the test market for these solar WiFi networks. Backed by Google, Meraki is making some serious waves in distributing wireless to the world. This innovation will be especially useful for setting up networks in developing countries a good distance away from electricity or network access. The solar kit will be available sometime in late 2007. Stay tuned.
Introducing The Wind-Powered Cell Phone Charger. Yup.
Looking for a portable charger? The world of renewable energy has lately been flooded with gadgets of all kinds featuring solar panels and hand cranks offering you endless opportunities to stick it to the man and get your juice for free. Up until now, wind energy has been left out in the breeze. No longer.
Orange, the U.K.-based telecommunications firm, has announced plans to launch The Orange Mobile Wind Charger, a mini turbine that “latches on to the top of a tent and stores power in a separate “control box” that users can plug into when their mobiles need juice.”
The Smart Jitney: Rapid, Realistic Transport
Community Solutions recently issued a report about modifications necessary to our transportation infrastructure in a future world where we experience declining oil supplies. (Community Solutions, if you aren’t familiar with them, is the group that created the documentary “The Power of Community: How Cuba survived Peak Oil”) They are proposing a system they are calling the Smart Jitney, which is essentially a souped up ride share program designed to reduce the amount of cars on our roads. And I have to say, I like it. I like it a lot.
I recently read through a report by Alliance Bernstein about the future of automobiles where they placed all the marbles for our future transportation needs in the plugged in hybrid basket. Essentially making quite a few difficult, and risky, assumptions that we will be able to sequester power plant emissions (unproven), generate clean energy for our homes and cars (not at the levels we are generating now), and create a new infrastructure built around a totally new type of car (to the tune of hundreds of billions of dollars). In short, they are making some huge leaps there to support their given choice for transportation.
Summer Groove: Solar Pool Fence and Solar Garden Shower
Even though it’s April 16th and there’s 16 inches of snow on the ground here in Ithaca, NY, I’d like to think that I might have a use for these innovative products sometime soon. That is, if I can even get my hands on them.
First up is a “Professional Solar Garden Shower System” called the Solar Fizz. This portable showering unit uses reflector tubes to capture solar energy and heat water to 70+ degrees Celsius. Each tube can hold 15 liters — with a complete system capable of providing hot water for an entire family. Each of the units displayed on the website is claimed to be portable; but even the 15 liter version might be a little unwieldy if you plan on roughing it somewhere. The only problem is that the technology is limited to a few countries in Europe and Asia. They’re looking for distributors in North America; no any of you eco-entrepreneurs out there — have a look! Outdoor showers are the bomb-diggity — especially pollution-free, hot showers.
The Transparent Banana?
There was something slightly obscene yet engaging about the title of this post, so I had to re-use it. Chews Wise, written by Samuel Fromartz, the author of “Organic, Inc“, has a very interesting post up about how transparency is beginning to show up in the grocery store:
Dole revealed a shape of things to come in the food market – Transparency! – by allowing customers to see where their bananas come from.
Visit its Dole Organic web site and punch in the number on your banana SKU sticker. (Not the SKU code, which is 94011 for organic bananas but a three-number code that identifies the farm.) The web site shows you where this code is located.
Citizenre PV: Coming to a Roof Near You?
Imagine if to go wireless, mobile phones companies made you purchase a kit to install your own tower for $8k, and then shipped you a box of minuscule widgets and a soldering gun that you have to somehow assemble into a Razor. I’m pretty sure the market density of cell phones would be about as weak as that of PV, because that is the marketing strategy that Solar Energy is currently operating under.
Now imagine you could sign a contract, and have clean, green solar energy installed at your home by professionals and pay a nominal monthly fee based on your usage with no initial outlay. Tempted? The Citizenre Corporation is counting on it. What they are offering is the chance for average Americans to have the privilege of a Solar Array on their roof. According to their website it will be as simple as having one of their technicians do a site assessment, the signing of a 1,5,or 25 year forward rental agreement (FRA) and a safety deposit of $500 (reasonable for $25k in equipment!). At the signing of the agreement you will lock in your current cost per KwH and pay Citizenre that amount for any watts their equipment sends into your home thru an interconnected inverter. For anyone who is remotely Eco Aware this is Earth Shattering. But that elation is followed immediately by “where’s the catch?”. Talk to a REnU rep and they answer simply “there is none!”. Hmmm.
EcoForms
Wow, here’s another West Coast only first! In Santa Rosa, CA (just north of San Francisco) there is a company that makes pots for your plants, flowers, herbs, and such out of sustainable crops, mainly grain husks. They’re called EcoForms.
Now from what I understand, such a product already exists in Canada, the UK, and Australia. EcoForms is the first here in the US (but correct me if I’m wrong). They are a husband wife team who run an organic nursery called Sweetwater Nursery. Like most things borne out of necessity; they wanted an alternative to the plastic pots. They had already converted their greenhouses to solar power and their trucks to biofuels, but the plastic containers for their organic plants just seems contradictory, hence an idea was borne!
They are designed to last 5 years in all climates. and come in a variety of earthy colors and different sizes. If you decide to discard it into a landfill, it will breakdown into a nutrient-rich organic matter with a PH value of 7.0. You can find them at Whole Foods or contact them directly for wholesale orders, or custom designs.

Amish Busted Over Raw Milk
A recent article on the illegality of selling raw milk caught my eye.
“Arlie Stutzman was busted in a rare sting when an undercover agent bought raw milk from the Amish dairy farmer in an unlabeled container.”
On the surface it would seem that the government agency responsible for this sting has way too much time on its hands. Further investigation into unpasteurized milk reveals that it can carry harmful bacteria. It is also true however that the pasteurization of milk does has negative effects that are seldom discussed in the press.
The pasteurization of milk:
- Can be used as an excuse to sell low quality milk
- Can be used to cover up unhealthy milk production practices
- Destroys beneficial bacteria
- Reduces the nutritional value of milk
- Reduces the vitamin content of milk
- Destroys valuable enzymes
- Provides an excuse for harmful animal husbandry practices
- Diminishes the taste of the milk
- Provides a false sense of security in this fallible practice
