Absolut energy efficient. Mucho respect for these modern day Da Vinci’s at Festo!
Where some people hear noise, Jeong Ho You hears energy. “Acoustic energy is everywhere,” he says. And with the help of a tiny resonating chamber, he wants to trap some of that energy and convert it into a low-amperage current for use in small electronic devices. You, a mechanical engineer at Southern Methodist University, in Dallas, will be presenting the results of a computer simulation of a resonating chamber design at next month’s Acoustical Society of America meeting in Seattle. He then plans to build a device to see how his idea holds up in the lab. Read more…
Each day for 30 consecutive days Dominic attempted to make something creative. In hope to force himself into making quick decisions, creating things instinctively.

Electric vehicles had many advantages over their competitors in the early 1900s. They did not have the vibration, smell, and noise associated with gasoline cars. Changing gears on gasoline cars was the most difficult part of driving, while electric vehicles did not require gear changes. While steam-powered cars also had no gear shifting, they suffered from long start-up times of up to 45 minutes on cold mornings. The steam cars had less range before needing water than an electric’s range on a single charge. The only good roads of the period were in town, causing most travel to be local commuting, a perfect situation for electric vehicles, since their range was limited. Read more here. (via liftlab)

Scientists from Korea have turned the main ingredient of calamine lotion into a tiny material that converts sound waves into electricity. The research could lead to panels that can charge a cell phone from a conversation or provide a boost of energy to the nation’s electrical grid generated by the noise during rush hour traffic.
“Just as speakers transform electric signals into sound, the opposite process — of turning sound into a source of electrical power — is possible,” said Young Jun Park and Sang-Woo Kim, the two corresponding authors of a new article in the journal Advanced Materials.
“Sound power can be used for various novel applications including mobile phones that can be charged during conversations and sound-insulating walls near highways that generate electricity from the sound of passing vehicles,” the co-authors added.

Interesting to see how angel investors think or make their decisions. It’s really useful knowledge if you like to pitch your idea to one or just to see and judge if your business idea is in a good spot.
1) “Drill more holes”. Investing in many companies is the only way to balance the risks of markets, teams and competition. Maintain a relatively large portfolio.
2) If you can’t judge the team, market and product thoroughly, it’s probably not a wise investment.
3) Keep some powder dry for subsequent rounds. While the best return in a successful investment comes from investing earlier, holding some cash back can mitigate some risk.
4) Don’t make assumptions during the honeymoon. While making an investment, you’re probably seeing the company in its best light. Things will likely get worse before they get better.
5) Team over idea – Ideas are cool, but quality teams are cooler. A great team can make a mediocre idea soar or morph it into a better one over time. Often, mediocre teams struggle to create success even when they start with a great idea. I have to believe that the team can knock the ball out of the park. Only then do I consider the idea itself. As a corollary to this, I need to trust the CEO. Surprisingly, I find this to be a real issue from time to time.
6) There has to be a grownup involved – For all the energy, drive, brains and talent in most startups, there’s often a dearth of wisdom. Someone needs to be involved to provide it and be a sounding board for the startup team. This person or these people should be on the company’s Board of Directors. They can come from inside or outside of the investor group (inside preferable).
7) You can’t and don’t even want to try to tie up every loose end – As much as you’d like everything in the investment to be taken care of and completely thought out, it ain’t gonna happen. Things change along the way. The investor and founding team need to feel like they will make adjustments together as warranted.
8) Friend’s before business – This is a personal rule of mine that I’ve broken more than once. Fortunately, it’s never backfired on me. I take both my friendships and my involvement with companies seriously. As such, the potential for conflict is high if I mix them – things never go the way you plan. There are always going to be situations in which the investor needs to support either the company or the management team. Can you support the company over your friend? Your friend over the company? Why even put yourself in that position? (via Venturebeat)
Thermoelectric wellies that charge your mobile phone using heat from your feet
Orange today unveils the Orange Power Wellies, a groundbreaking and innovative eco mobile phone charging prototype created to keep Glastonbury Festival goers connected with their friends across the weekend.
The Orange Power Wellies, created in collaboration with renewable energy experts GotWind, use a unique ‘power generating sole’ that converts heat from your feet into an electrical current. This ‘welectricity’ can then be used to re-charge your mobile phone. Orange, Official Communications Partner for the Glastonbury Festival, will be showcasing the Orange Power Wellies prototype onsite…(read more)
Toulouse, in south-east France, is experimenting a new pedestrian crossing system.
The local authorities have set up a temporary pavement made from eight suspended Plexiglas slabs. The vibration caused by walking on the plates sets off a series of vertical and micro movements which are converted into electricity. That is enough to generate up to 50 watts, sufficient to illuminate a set of LEDs and a street light.
The system is supplied by the Dutch company, Sustainable Dance Club who gained their reputation by setting up anexperimental energy-generating dance floor where part of the lighting was supplied by the movement of the dancers themselves.
