Your roommates steal all the phone chargers so you have to charge your phone at work.
Just make biodiesel from these crazy life forms that sequester carbon from the CO2 air using energy from the sun, I think they call them "plants". Or Audi could buy out the patent and make cars that just run off of vegetable oil. This seems like a really convoluted way to get diesel when you can just take hempseed oil and add methanol.
He's not going to get a building named after him ever...
Provided you make a warning against doing just that it's okay. During alcohol prohibition breweries used to sell malt extract with a warning that went something like "don't add water and yeast and leave in a dark room for 3 weeks, it will make alcohol and that's illegal!"
Here in Milwaukee it already takes a couple of hours to get a cab at 2am, that is, unless you call uber
I've lived here in Milwaukee on and off for the last decade or so, and I can tell you right now this is the right decision for our town. Milwaukee is a city whose economy is entirely based on alcohol, that being said we have had awful cab service for as long as I've lived here. All summer long drunks flood the street for this festival and that festival, and every weekend the wait for a cab is frequently over an hour, sometimes it takes 20 or 30 minutes just to get on the phone with a dispatcher. Seeing as how the underfunded and overpriced bus system stops running an hour before bar close what we end up with is a plague of drunk drivers. Our cab companies have failed to provide us with the proper service we need (presumably because of the cost of keeping up an unused fleet in the winter months) , Uber gave the city an alternative and we made sure nothing would impede the solution to our problems.
' in which yeast eat the sugar and excrete ethanol.'.
This is not exactly correct either, the yeast do not 'eat sugar and poop alcohol', in actuality the yeast, after running out of oxygen in the air (or without access to air in the case of bottom fermenting yeast) 'breath' the exposed oxygen off of the sugar molecule, what's left behind is alcohol.
Think of the implications when criminals and everyday citizens get ahold of the police GPS data. How convenient would it be to have a map of the city with a little blip showing the position of each cop car if you were say, trying to plan a murder, or smuggling methamphetamine. You could track the rounds each squad car takes over the course of weeks and plan the perfect route to avoid any intervention. Not to mention the end of speed traps as we know it.
The free point to point mesh internet needs to become a reality. The internet will never be free and open if it is controlled by massive telecommunications conglomerates, we need an internet that relies on a P2P network of high powered wireless devices. The original computer networking relied on direct ham radio connections between points, if this method could be improved with higher bandwidth and disseminated on citizens band frequencies so the FCC couldn't touch it we could make the internet as untraceable as a Tor network. This is a challenge for engineers concerned with the direction internet regulation is going. With private space travel becoming a reality one could even foresee a network that relies on private satellites outside the jurisdiction of any nation, and the only cost to access it would be that of the devices you use to connect.
I have a theory that it's impossible to prove anything, but I can't prove it.
