    • Some of you have noticed that when you start a conversation on Cake there is a placeholder to choose a panel. We're still working on this feature. I imagine panels being similar to this Q&A with Bill & Melinda, where a small group is allowed to post without a thousand people interrupting the flow.

      I found this panel-like Q&A to be fascinating about where they donate their money and why.

    • Chris, I have only started one conversation so far and I think I have noticed it. In general, I believe Cake's interface is very clean and I love that.

      I am reacting to Bill's comment on climate change (#3), as it is a space I am intimately involved with:

      "Personally, we’re investing in innovations that will cut back on greenhouse gases (what’s called climate-change mitigation). The world needs new sources of reliable, affordable clean energy, but it has been dramatically underfunding the research that would produce these breakthroughs.

      This funding gap is different from the problems we work on at the foundation. In philanthropy, you look for problems that can’t be fixed by the market or governments. The clean-energy problem can be fixed by both—as long as governments fund basic research and create incentives to reduce greenhouse gas emissions and investors are patient while companies turn that research into marketable products. That’s why I’m working on it personally rather than through our foundation." - B. G.

      Compared to all other sectors, industrial cleantech is the hardest to commercialize. Even big pharma does not require the capital (hundreds of millions) and time (>10 years) that it takes to innovate on energy. Those who talk directly to Bill Gates report that even he is disillusioned, as he does not see a way to break the stranglehold of petrochem and chemical giants, especially when petroleum and natural gas remain tanked, and nobody puts a price on carbon emissions.

    • I worked for 10 years as a geophysicist in environmental, natural gas, and oil. After 10 years, I was disillusioned too and migrated to the computer industry.

      The hardest thing for me was environmental cleanup. When there is a major chemical spill and it gets into the water table, how do you clean that up? If it spilled on your shirt, that would be hard to clean. But 100 feet into the soil, being transported by groundwater? I think that's a job that's even too tough for Tide, and it gets out the toughest stains. 😢
