   Thanks so much! It does look like it's had a little traction. I'm glad to see that. I'll check it out and pass this along to friends who have been asking.

   People will never understand Tesla's value if they don't understand that Tesla is more than just a car company. (But no comment on the current stock value.)

   Fixing our PPE supply chain was/is a solvable problem that our governments have utterly failed to address properly. It is shameful that our federal and state governments haven't better organized and incentivized solutions to fix t

    As I understand it, many COVID19 deaths could be prevented if cities didn't run out of ventilators. What open-source good-enough version can we mass-produce in a hurry? This isn't my project. But I was thinking along similar lines

    I experimented with a similar idea, but with a solution that I think is simpler. My idea is called "Skipper": A dead-simple password keeper that is end-to-end encrypted, open-source, and free. A master password syncs your encrypte

    In the chart from the article I see that capacitors are shown as having high specific power. Would it not work to use a hybrid approach of capacitors for takeoff and then Li-ion for most of the flight? I know it would make the system more c

    ^ That's pretty darn cool, thanks. Among the things you'll learn: - Around 4000 miles into Neptune's crust, there is a sea of hydrogen where carbon crystallizes into diamond which falls like rain to the center of the planet

    Good question, it doesn't really need to be, those numbers are partly just to visualize it. But we do have some reasons to keep it with more surface area: - less digging - less reinforcing needed - it's more stable - In some ca

    yup! More fun facts about a 1 km head height... Off-the-shelf turbines are actually spec'd for a max head height of something closer to .5 km. So the design calls for a double-drop. This design approach is taken from the DOE research

    Hmm, I think what you're alluding to is that pumped hydro is about 70-85% efficient and Li-ion is sometimes quoted at 100% efficient (in theory). But here are some more details. In reality, when Li-ion batteries are installed in a larg

    If we attach our installation to an existing reservoir, we'll take up nearly zero land above ground. If we build a new self-contained upper reservoir it will be about 0.5 miles on each side and 40 feet deep. It can be built with materi

    I love this quote: Hydro pumped storage is “astoundingly efficient…In this future world where we want renewables to get 20%, 30%, or 50% of our electricity generation, you need pumped hydro storage. It’s an incredible opportunity.” – U.S.

    Thanks! Yes, and our research agrees that the short-life of Li-ion is a problem, and it's one of the reasons why we believe our solution has so much more promise than Li-ion for grid scale storage. The pump/turbine technology we u

    Yup, though we don't consider it a problem, that's just the simple math. Our solution tunnels down 1 mile deep and excavates an underground reservoir. While this may sound extreme, it's entirely feasible and cost-effective. W
