Delta T - getting more power from Magma.
There are only two “sources” of energy: sun and earth.
Sun creates solar energy, heat, wind and waves. Earth has geothermal heat and momentum. Earth’s rotational momentum manifests itself in tides, because of the moon’s pull on water. Geothermal energy is everywhere, but can be hard to access. We’ve got to get creative.
Make it stand out.
Delta T is about making (or saving) energy using earth’s heat.
Tapping into the heat underneath the earth’s crust is risky and expensive. To defray that cost and risk, Delta T is all about tapping abandoned oil and gas wells to find the heat. In 2002 and again in 2011, I researched the “Idle Well Programs” in California and Texas in an effort to find more cost effective heat. We did a data science exercise to focus on the top 5,000 wells - using proximity to the grid, energy demand, prices, incentives and temperatures from old well logs to narrow the search from 2 Million wells. Today, it is a viable strategy to find heat for energy, heating and even cooling. It can also be a cost-effective source of minerals like Lithium.
Delta T is everywhere
Why not use tap water and waste water as a temperature sink?
Water has a tremendous amount of latent energy in its temperature, and water flows through pipes underground every day to the tune of 34 billion gallons per day. By using pipes to cool or heat our buildings by 10 degrees, we could save up to 830,000 MWh per day. That’s 60 full time coal plants! (Think: water treatment plants as a source of thermal energy and organic matter).
