The hottest Technology Innovation Substack posts right now

American wildcatters, known for oil and gas, are now turning to nuclear energy. This shift shows a big change in how the U.S. thinks about its energy sources.
The new energy policies focus on nuclear power, marking a major change since the 1973 oil crisis. This push aims to reorganize America's entire energy system towards nuclear and away from renewables.
Key players in promoting nuclear energy are experienced in the shale industry. Their background might help speed up the development of new nuclear technologies and reactors.

Technology change isn't straight and slow; it can grow rapidly in an S-curve pattern. This means innovations can spread faster than some people expect.
We should focus on the new technologies coming into play instead of just looking at what we have now. What's happening in the present will give us a better idea of what's to come.
Energy efficiency has a bigger impact than many realize. It's important to pay attention to how we can use less energy rather than just relying on new sources.

Capturing CO2 at scale won’t magically solve emissions because most industrial uses of captured CO2 release it back to the atmosphere, and the market for permanently storing or using that CO2 is tiny compared to global emissions.
Doing this properly would need massive, expensive infrastructure—millions of miles of pipelines, huge geological storage, and rebuilt steam networks—which is likely economically and logistically unrealistic at the scale needed.
Even if the technology works, investors and policymakers can create a lot of costly, symbolic projects (virtue theater) that don’t deliver permanent climate benefits and may just enrich startups or rely on short-term subsidies.

Investing in space tech has huge potential. It's becoming a key part of important industries like defense, agriculture, and communication.
When looking to invest early, focus on the founding team and the size of the customer market. Successful relationships can be built before a product even exists.
Finding big problems to solve is better than starting with a tech idea. Look for large markets that could benefit from smart space applications.

Space missions allow for important medical research that can't be done on Earth. This research helps us understand health impacts from weightlessness and cosmic radiation.
Space medicine focuses on preventing and treating health issues astronauts face during missions. It's essential to manage their wellbeing in orbit, especially for long-duration flights.
The future of space medicine includes private companies conducting research in space. This could lead to breakthroughs in treatments for diseases like cancer and Alzheimer's.

Guns are currently outdated technology that requires a lot of training to use effectively. Most people find it hard to learn how to shoot well, which is a problem for self-defense.
There are newer technologies being developed, like electromagnetic guns and suppressors, that could make self-defense easier and safer. These innovations could provide better options than traditional firearms.
In the future, it’s important to focus on creating better self-defense tools. Making these tools easier to use will help more people feel confident and capable in protecting themselves.

It's important to consider the original goals of organizations, like Y Combinator, which focused on providing fast experimentation and proof-of-growth.
Deep tech VC can benefit from a model inspired by mid-20th century research organizations that focused on profitable problem-solving and spinoff companies.
Collaboration with applied research professors at universities and shaping projects for future VC investment can enhance the quality and viability of deep tech investments.

Single primitives are the smallest problem-solving units in creating best-in-class products.
Building primitives with existing technology ensures stability and relatability to users.
Stacking primitives and emphasizing features over forks can lead to exponential product value over time.
