Review of Topics in Business (PMBA)

In preparation for a business-related internship, I’m reviewing topics in micro- and marco-economics, and after that will review topics in business. I’d like to point out that my favourite book on MBA and business so far is, hands-down, the Personal MBA


Buy it, and read it twice. Take a look also at the list of books i recommend.

Similarly, the Harvard Business Review offers a lot of interesting articles on business, and is available here:

Water Harvester: This new solar-powered device can pull water straight from the desert air

So who is working on having this mass-produced? Obviously some organizations and maybe governments would be interested in seeing this generally available.


You can’t squeeze blood from a stone, but wringing water from the desert sky is now possible, thanks to a new spongelike device that uses sunlight to suck water vapor from air, even in low humidity. The device can produce nearly 3 liters of water per day for every kilogram of spongelike absorber it contains, and researchers say future versions will be even better. That means homes in the driest parts of the world could soon have a solar-powered appliance capable of delivering all the water they need, offering relief to billions of people.

The new water harvester is made of metal organic framework crystals pressed into a thin sheet of copper metal and placed between a solar absorber (above) and a condenser plate (below).

There are an estimated 13 trillion liters of water floating in the atmosphere at any one time, equivalent to 10% of all of the freshwater in our planet’s lakes and rivers. Over the years, researchers have developed ways to grab a few trickles, such as using fine nets to wick water from fog banks, or power-hungry dehumidifiers to condense it out of the air. But both approaches require either very humid air or far too much electricity to be broadly useful.

To find an all-purpose solution, researchers led by Omar Yaghi, a chemist at the University of California, Berkeley, turned to a family of crystalline powders called metal organic frameworks, or MOFs. Yaghi developed the first MOFs—porous crystals that form continuous 3D networks—more than 20 years ago. The networks assemble in a Tinkertoy-like fashion from metal atoms that act as the hubs and sticklike organic compounds that link the hubs together. By choosing different metals and organics, chemists can dial in the properties of each MOF, controlling what gases bind to them, and how strongly they hold on.

Cold Lead Generation

How do you find startups that need project work? I posed this question to my brother in a phone conversation the other day. I said to him, tech crunch / crunch base comes to mind, and he said that the top earners on upwork and odesk and elancer are a good list of potential clients.

From my point of view, the interesting companies are those that are in high tech and just got the money to spend on R&D (research and development). Notably, tech crunch publishes lists of such companies.

From my brother’s point of view, remembering the days when he was a freelancer, his analysis was as follows. The majority of projects on elancer (or any freelance site) are <$100, or $100-$500. However, top earners pick the >$500 projects. And those projects are likely to run for months or years. And the clients who need such projects, are the interesting clients.

There is also cold calling, of course. Grab a yellow pages book and start looking at each company, one by one. I feel that I should try doing something like this, just to get experience with sales.

And with that, I saw a whole lot of companies to reach out to. So I think it’s not a tremendous problem finding the companies that need the services that we offer. It’s more important to maintain a good presence (online and in-person), and most importantly, offer relevant & competitive services.

Here are some lists of companies that may need tech, just for reference:
