ALTERNATIVE ENERGY

CalSol: UC Berkeley Solar Vehicle Team


CalSol, the UC Berkeley Solar Vehicle Team, is a non-profit organization whose purpose is to design, build, test, and race fully solar-powered vehicles. Composed of over 50 undergraduate students from a variety of disciplines, CalSol provides students with hands-on experience with real world engineering, project management, and business aptitude. They will display their 7th-generation car named Impulse, which placed 4th in the 2012 American Solar Challenge.

Solving Climate Change with Biomass


To solve climate change, we need to do more than just plug in solar panels — we have to get carbon out of the sky and back into the ground. Biomass gasifiers do that by turning organic waste into on-demand, renewable, carbon-negative energy. All Power Labs will bring a compact biomass gasifier genset, which will turn waste nutshells into electricity. The remaining residue, known as biochar, is a great fertilizer — they’ll offer free sample ziplock bags to the public to put in their gardens.

Siege X-Stove


Come try the Siege X-Stove, the most versatile, rugged, and affordable camping and survival stove system on the planet. In addition to being the favorite stove of countless outdoors enthusiasts, campers, backpackers, preppers, and bushcraft/survival instructors, the California-made Siege Stove is also uniquely suited to developing nations and disaster relief. Its efficient use of minimal biofuel wood scraps (instead of bulky, expensive resource-intensive gas and synthetic fuels) can help reduce deforestation, with the unique benefit of giving common cans a second life (reuse is even better than recycling!). This and its ability to make a cleaner-burning gasifier stove from two interlocking cans gives it advantages that no other stove has. Siege X-Stove is also practically indestructible, unlike most other proposed cooking solutions.

Homemade Microbial Fuel Cells


Los Gatos High School student Cassandra Melax will showcase how to make simple microbial fuel cells mostly with materials one can find at home. All you need is a plastic container, mud, wires, and thin sheets of carbon cloth. She’ll be bringing a few fully functioning fuel cells as well as the individual parts to explain how it’s set up. The exhibit will include an explanation of how bacteria power these fuel cells, how batteries generally work (including those that use salt bridges), and the types of environmentally friendly energy production that are available today.

Biomass Rocket Stoves


InStove (Institutional Stove Solutions.) is a nonprofit that designs institutional biomass rocket stoves and allied technologies for use where fossil fuels or electricity are insufficient or unavailable. Come learn about how biomass can be used to sustainably meet energy needs at home and abroad! InStove (Institutional Stove Solutions) is dedicated to relieving suffering, improving health, and reducing harm to the environment through renewable energy technology and education.

The BellyRacer


Behold this electric go-cart where you lay on your belly. Originally built for Burning man by lifelong maker Karen Schwartz, this go-kart initially ran off of a lithium-ion battery but it has gone solar and now uses a 250-watt solar panel.

PEDAL POWER

Cyclecide


Come ride with Cyclecide’s pedal-powered carnival! They’ll have the Bike Coral, 20 modified bikes, including tall bikes, choppers, sidecar bikes, bumper bikes, swing bikes, and more! Plus, check out the 32-foot-high Axe-Grinder, the four-person Cyclo-fuge, the Whirl-n-Hurl, and the Kiddie Carousel.

Frankentrike


What if you could ride a bike that was sort of like a car with most of a car’s features and few of the drawbacks? Meet Frankentrike, the all-purpose ideal form of personal transport for the dense urban environment. Frankentrike is all about showing people that we can get around without a car in our cities, but in a way where the benefits far outweigh the challenges.

The Pedal-Powered Stage


Rock the Bike invites you to come pedal-power live music performances from talented local bands and take part in the Energy Challenges, where you can go head-to-head with common electrical devices, trying to power them with your legs. This year, the Pedal-Powered Stage will feature 24 bikes, all kid-friendly, plus four adult-specific bikes.

FANTASTIC PLASTIC RECYCLERS

Green Engineers: The Tool Chain

For the last two years, Steven Mosbrucker’s main focus at his one-man invention shop The Green Engineers has been the Tool Chain, a recycling micro fab including a shredder for recycling thermoplastics (The Reclaimer), a filament maker (Multistruder/FilaFactory) to turn the recycled thermoplastics into 3D printer filament, and a 3D printer (Simple Cubic) to use the recycled filament. With these three machines, you’ll either be able to make endless filament and print from pellets or go completely green by recycling plastic or recycling failed prints.

The Super-Amazing Plastic Bottle Boat


The Super Amazing Plastic Bottle Boat Project team is comprised of four 2nd-grade students from Oak Knoll Elementary in Menlo Park, California (plus one little brother). They tested the best way to tie string together in order to build a boat out of plastic bottles, string, and twine.
