Methane is responsible for ~30% of the planetary warming we experience today. While it is short-lived in the atmosphere, it is far more potent while alive than carbon dioxide: around 85x more.
At Moxair, we are developing systems that convert methane into carbon dioxide and water using our proprietary catalysts and reactors -- greatly reducing the emissions impact of coal mining, dairy production, and oil & gas operations.

Over 80% of Americans are worried about climate change, but 99% of Americans don’t have the option to make climate-friendly investments. Sphere makes climate-friendly investing available to everyone, by making it easy for employers to offer climate-friendly options in 401(k) retirement plans.
A number of family offices and institutions have already stoped investing in the fossil fuel industry, often citing worrying economic factors and a need to protect long-term value as a driving force for decisions, including the Rockefeller Foundation, the New York State Pension Fund, and the Harvard Endowment.
Sphere helps advisors and employers demonstrate their commitment to fiduciary duty with a high-quality product at reasonable fees while satisfying a deeply personal desire of clients, without having to choose between the two. The Sphere 500 Fossil-Free Index tracks the Top 500 US companies by market capitalization and excludes fossil fuel companies to avoid stranded asset risk. The fund votes shares for the planet, not for the status quo.

The impetus for Virtus Solis is to provide clean, low-cost renewable energy that directly supplants primary energy production for all terrestrial uses and eventually even extra-terrestrial. Fossil fuels power 85% of the world in a non-sustainable fashion. This must change. There are limited options for disruption because terrestrial renewable power is intermittent - it is seldom available when and where needed. Ubiquitous, inexpensive and clean energy are desperately needed. Cleaning up electric power requires replacing the equivalent of more than a million tons of coal use every day for the next 30 years. But even that is not enough. Globally, most of the planet’s population suffers from energy poverty, and access to low cost energy is the greatest lever for universal prosperity. Limitless low-cost energy solves these problems and promotes sustainable growth and harmony.
Virtus Solis is the first low-cost space solar power system able to address the entire $8T energy market.
