Geothermal Energy. Extremely simplified, all you need to do is drill a hole deep enough for a high temperature difference. Then stick in two pipes, on for sending water down, one for steam to come up. Run a turbine, add a valve to regulate how much water you want to converted into steam to be able to regulate output, enjoy your first mover advantage and price the competition out of the market. ... It's not that I do…

On bigger scale, it seems this can sometimes cause earthquakes... One geothermal power plant is going to close in France https://www.connexionfrance.com/French-news/Geothermal-power...

That is correct, but not for the "two pipe approach" I outlined in my post.

There is a form of geothermal energy generation that is being used here, that injects water into the ground and taps into the heated water. This is somewhat similar to the way fracking is performed to extract oil and gas from the ground, but it's not the only method.

But to your point - to me it is surprising that these issues aren't being "worked on more".

Yup. The earth's crust is less than 1% of the earths radius. Just below the crust is all the energy we would ever need for a long long time.

Effectiveness and chemical makeup of home remedies/ancient medicine. I know there is no money in researching non patentable chemicals, but I'm surprised that governments are not sponsoring the research

Collection of environmental/lifestyle information of cancer patients. I know it would lead to a ton of stupid headlines, and correlation does not equal causation, but I think if you have cancer they should ask where you live what you eat what products you use and whatnot. Atleast for the cancers that do not have well known causes.

Superficially, why is there no standard video streaming api. Do content/platform owners really want to be in the app business? They are all bad it.

Computing tools for non—programmers. In the early days of computing, we quickly came up with the spreadsheet and the user-friendly relational database (Access, FileMaker). Then we just sort of stopped. The no-code thing today is a step in that direction, but we could do so much better. I’m actually ashamed of the software industry that we have done so poorly at this.

I recently thought about this, too. Is there any cloud-based, simple relational database, aimed at non-programmers?

Innovation in the mental health care space. Right now most of the top funded startups are working on either 1) Simplifying access for wealth people to the already available supply of therapists; or 2) Removing the human component entirely by creating with apps which have very little evidence to back them up.

I see mental health care as one of the most important problems of out time, at the root of so many of the issues we see in society today. Yet government has been very slow to act, which in turn means insurance companies don't modernize their reimbursement policies, which then stifles innovation.

Markdown for academic papers. We have this https://github.com/tompollard/phd_thesis_markdown (which is the best template I know and on a personal note I've written my thesis with that too) but the whole ecosystem can be still improved.

I wrote my thesis with Markdown, combined with pandoc. Worked out allright. I think Overleaf supports Markdown now as well, which might be a more practical approach for those not familiar with git/make/shell.
