I like this idea. If any rent-seeking group achieves market dominance, the government should regulate their prices. For example, the price of prescription drugs and higher education should be set by the government. Laissez-faire capitalism

Actually, the US is described as the Saudi Arabia of wind. Most of the potential is on-shore which has better economics than off-shore also. http://www.pickensplan.com/wind/

There is also the option of part-time consulting to pay the bills while building the startup. As a Django consultant, this person could probably make $50k annual income by consulting a few days per week. The rest of his time could be dedica

Was the Xbox 360 really a huge success? It came second or third in sales for its generation of consoles. 75 million units in seven years is a small number compared to mobile devices. Android sold 144 million devices in Q4 2012 alone. I thin

I like the Australia idea, but I'd save up $10k before departing. Relocating to another country is expensive. I suggest to find some freelance programming jobs online. He could make some money writing articles about the stock market for See

Stefan, Lower your expectations. Be grateful for your health and living in a developed country like Switzerland. You have awesome mountains there. Startups are an escapist fantasy for millions of people. I would guess 99% of web startups ma

I agree that home robots will be task specific and not anthropomorphic. Examples I would buy if they were cheap: -robot to stack and unstack the dishwasher -robot wheels to put the garbage bin out for weekly collection -robot mower to cut t

Air pollution has dropped 50% judging by the chart in this article. Much better than the LA Times prediction. http://www.mnn.com/green-tech/transportation/stories/study-c... I guess they were too optimistic on the home robot. Hopefully, t

OK, I am sold on Go as my next language for web applications. Unfortunately, I can't throw away the existing PHP/MySQL code. Any suggestions on how to integrate Go and PHP into a single web server? Should I be using FastCGI for Apache to ca

If it hits Mars, it could help to terraform the planet. The CO2 ice caps would melt and heat the atmosphere. It would melt a significant amount of frozen water in the soil and thicken the Martian air with water vapor too. Wikipedia is predi

Yes natural gas overtook coal as the leading source of electricity in the USA. The transition was in 2012.

I enjoy driving electric too. Electric motors are quiet, clean and responsive. There are 18 models of plug-in hybrid coming to the market by 2018. I think the hybrids will sell better than the pure battery vehicles as they don't cause range

The Chevy Volt has a data link and remote apps for IOS and Android. There's a web API that allows sites like Volt Stats to download from thousands of cars. The Chevy is not a $15000 car, but the prices are dropping. The Nissan Leaf can be b

Let's hope they land humans on the Moon and Mars in the next 13 years. Elon has much more capital now than back in 2002. They are the most likely company to settle space.

Good point about false positives. The device could upload images to a human operator who would activate the defenses. This would add some reaction time, but it would reduce the potential for false positives. If the device has image recognit

A low-cost clone could be mounted on the ceiling in a room. Some stun grenades and tear gas would disable the shooter anywhere in the room. This would be a cheap solution. Include a wireless mesh network connecting the devices, and they cou

An automatic gun defense device like a smoke detector that is cheap and ubiquitous. The device should cost $100-$200 and could be installed in schools, shopping malls, cinemas and street lamps. If the device detects a gun-shot, it locates t

We need the FDA to regulate drugs and medical devices. There's too much potential for quackery. I don't think removing the FDA is going to find a cure for diabetes. It's a fundamental research problem at this stage. Stem cells are showing s

Totally agree. Learning object oriented frameworks gives me a headache. I learned C back in 1991 for first-year CS classes. Consider all the software built in C: Linux, FreeBSD, Apache, etc. It's the dominant infrastructure of the web. What

I think the point is to ride in a limousine across the tarmac and then step directly onto your jet without any hassles. Direct point-to-point travel to any airport is convenient too. The Citation X can fly coast-to-coast in under four hours
