time to move beyond the windmill.
modern physics bring wind energy to the new millenium.
from 100 kW to 10 MW – the safest, most cost-effective, and truly scalable solution
at 300 m, wind blows 24/7 and is 1.6x more powerful than at 100m
catching high altitude wind offers a continuous, reliable source of energy:
our patented system is designed to harness the power of airflow:
the wing is filled with helium, making it lighter-than-air and crash-proof
this innovation allows a safe, automated continuous flight:
-90% less than an equivalent wind turbine

recycled and recyclable technical textile & tethers
no concrete foundations required on the ground
low wing travelling speed
a unique scalable design that adapts project of all sizes
our product scales to fit projects of all markets: from a small remote farm to a large wind farm for utilities
the key: no matter the project size, our product relies on the same three simple principles (high altitude wind, Magnus effect, lighter-than air)
we produce more energy daily
and MAG production peaks in evening when price spikes
autonomous solution for remote sites and small industries delivered in a container
3x to 5x cheaper than diesel, 100% renewable

Joseph S. Spence II is a global strategist whose career spans NASA, international diplomacy, institutional finance, and frontier technology. His work focuses on building systems that connect advanced engineering with financial architecture, enabling large-scale scientific and industrial transformation.
Joseph began his career at the NASA Goddard Space Flight Center Academy, conducting research in neural networks, semiconductors, satellite communications, genetic algorithms, and fuzzy logic under Dr. Gerald Soffen, architect of the Viking Mission to Mars. These early experiences shaped a lifelong commitment to engineering-driven problem solving and complex systems design.
He later served in international relations with the Government of Japan (Monbushō), developing professional fluency in Japanese and deep cultural insight while studying Zen, Japanese swordsmanship, and traditional cognitive disciplines. This global orientation continues to inform his approach to leadership, analytical rigor, and cross-border strategy.
Joseph went on to build a finance career across J.P. Morgan, Bank of New York Mellon, Standard & Poor’s, Goldman Sachs, and AllianceBernstein. At S&P, he rose to Chief Operating Officer and Co-Lead Analyst for a $144B portfolio, pioneering early AI-based approaches to credit modeling. At Goldman Sachs, he oversaw credit and risk for Technology, Media & Telecom; Structured Finance; and Real Estate across the Americas and EMEA. At AllianceBernstein, he served as Global Head of Risk Management for a $60B alternatives platform spanning real assets, private credit, venture capital, and special situations.
Joseph also works through his family office, Champion24x7 — collaborating with sovereign funds, royal families, and global innovation clusters. His family’s multi-generational focus on education, performance, and scientific progress has been featured in bestselling author Adam Grant’s Hidden Potential.
At wind fisher, Joseph serves as Chief Financial Officer, responsible for strategic finance, business development, sovereign partnerships, and capital architecture. His work centers on positioning Wind-Fisher as a next-generation renewable-energy platform—integrating high-altitude wind power, advanced aeronautical engineering, and multi-vector energy systems into scalable, globally deployable infrastructure. He leads efforts across investment strategy, industrial partnerships, commercial expansion, and long-term financing structures for utility-scale and frontier-market deployment.
Joseph is an alumnus of Columbia Business School (MBA, Dean’s List). He serves on the board of the NASA Academy Alumni Association and collaborates with the XPRIZE Foundation on global technology and innovation initiatives.
