Geothermal Steam

I woke up this morning with excitement in my veins. It's a chemical thing - I ate the right food yesterday or something - but I was wired to brainstorm. As I assessed my life and where I should go, I confirmed once again that for me, happiness will come from truly making a difference while I'm here on this planet. And the holy grail, once again, is developing abundant clean sustainable renewable power. And the idea came next: tap into geothermal energy deep within the earth's crust, ideally generating steam from water. Drill deep enough, inject water, and receive steam. Tap the steam either below the crust or at the surface. The catch: is "deep enough" too deep?

I called my brother, the jack of all trades, to vet the idea. He knows something about everything. And true to form, he knew something about this idea already. He had seen a documentary on a similar concept that is nearing production in the Australian outback.

Further research

The Australian site is covered briefly here:

• Small news blurb about GeoDynamics
• video

Alternatively called an Enhanced geothermal system (EGS) and Hot Dry Rock (HDR), it is a system where water is injected into hot rocks found a few kilometers below ground. The Wikipedia entry says "this technology has the potential to power the world at little or no cost to the population." Bullseye!

Geothermal energy has been around for a long time. In the US, it was investigated extensively back in the 1970's at Los Alamos. It has since been researched all over the world. Since the 1970's until recently, funding in the US has been minimal. The enhanced version of geothermal energy, where water is injected into the system, is now causing a lot of buzz. MIT led an interdisciplinary panel that produced this substantial report in 2006. MIT Energy Lab: (617)253-3401. The DOE has now targeted EGS with new funding.

List of resources:

• EGS and HDR entries at wikipedia
• MIT report that began the evangelizing of HDR
• EGS described by MIT professor
• information on HDR from the EERE office
• Started in 1970's
• California plant brought back after being abandoned
• 2007 funding status looked bleak with George Bush at the helm, until Senator Harry Reid objected
• Overview of a (non-HDR) geothermal plant

Research funding

Since much research has already been done, I will focus on expanding upon it towards achieving the following goals:

• conduct a survey of geothermal resources within 4km of the earth's surface
• include earthquake risk assessment in the survey
• compare benefits and costs of open vs. closed systems
• determine the project size (including number of injection and production wells) that has the maximum benefit/cost ratio
• determine the smallest project size that has a positive benefit/cost ratio (likely one injection and one production well)
• design a 4km well with minimal installation and maintenance costs
• create a working prototype

We're excited to try to get some research funding. I want to keep the research totally open and cooperative. No copyrights, no patents, no marketing. Ideally, the results of any research will be the ability of anyone with enough motivation to tap into this energy source. Opportunities:

• NSF funding
• Dan suggested Google Venture, but "overriding investment criteria will be ROI", which may not fit my philanthropic agenda. UPDATE: the more you dig, the more you find - google already funds it!

I am going to work on a grant application next.

Application

There is a currently a well-funded comprehensive grant opportunity available! Amazing, the stars are aligned.

Here's the application.
