Here’s another flashy concept that uses solar energy for transportation: the solar speedboat! Unlike the solar sailor we talked about earlier, the Dutch MK1 prototype is designed to travel at speeds up to 30 knots! In 2006 the Delft Technical University Solarboat Team raced the speedboat to first place in the Nuon Frisian Solar […]
Mother Earth News recently featured an extensive article covering instructions on building your own small-scale solar heating system for as low as $30. The 9 page tutorial includes step by step instructions from Don R. and George Waterman of Springfield, Missouri, and is based on their experience installing the system on their 30×40 insulated […]
According to a recent article from Greentech Media, a Massachusetts aerospace company called FloDesign is working on a wind turbine concept that could potentially be at least twice as efficient as traditional rotor blade turbines, which force air around them instead of through them. It works by channeling wind into a vortex that spins […]
California based company Green Vehicles recently began selling an affordable $20,000 electric car called the Triac. The small but efficient 3-wheeled car has a range of 120 miles and can travel up to 70mph on the highway. Charging the lithium-ion batteries that power the 20kw electric motor takes about 6 hours, and there is […]
With oil prices crossing the $135-dollar barrier the alternative energy company executives are really rubbing their hands in anticipation. In just May the oil prices have risen 20% and consequently the stock markets are panicking big time. Rising raw material costs, if not tackled in time, is definitely going to trigger an economic slowdown. […]
Google recently launched Earth Outreach as part of an effort to provide non-profit and public benefit organizations the knowledge and resources they need to reach hearts and minds in the ongoing struggle to raise awareness about global warming and climate change. Their environment and science showcase provides links to some of the more helpful […]
Remember the Solar Lily Pads? Well, Swiss inventor Thomas Hinderling has taken that idea to the next level with his solar islands concept (check out the video). The 5km wide, 20m height island concept would be mobile and would adjust according to the sun’s movement across the sky. Each island would generate hundreds of […]
The flowing waters in the rivers and tidal waves can be a good source of alternative energy. With 70% of the earth’s surface covered with water, a great amount of energy can be produced by placing turbines at strategic locations under strong currents. This method of generating electric power is called hydrokinetic power generation. […]
General Electric and the C-MAR Group recently announced plans to work together on the development of hybrid engine technologies for tugboats, in an effort to offer lower costs for customers and while lowering carbon emissions. The tugboat platform builds on current hybrid technology projects for locomotives, city buses and off-highway vehicles. These hybrid technologies […]
For the past several months the San Francisco Public Utility Commission (SFPUC) has begun picking up used cooking oil from restaurants and businesses for free in an effort to find fuel alternatives for its municipal fleet. The city hopes to expand the grease recycling program (called SFGreasecycle) to include small-scale household pickups and eventually […]
Bicycle sales have been booming in North America in recent years, with some sources saying high gas prices may be responsible for the trend. Bike shops are reporting high profits, bike lanes are expanding, and the web is exploding with useful blogs and websites designed to help cyclists. A few of our favorites are […]
The soaring oil prices and the rising level of awareness among the masses regarding the rapidly deteriorating environmental conditions are compelling many car makers to switch over the developing hybrid cars. There are already more than one million hybrid vehicles running on American roads (May, 2008). Big car companies like GM and Toyota have […]
Canadian Inventor Ben Gulak of BPG-Technologies has developed a wild new green motorcycle that uses gyro technology to stay upright on its two side-by-side wheels. Acceleration is controlled by leaning forward to go faster, and leaning back to slow down. The gyro tells the ECU how much to accelerate and that in turn delivers […]
The National Research Council of Canada’s Biotechnology Research Institute has begun research and development of a process that will extract hydrogen from organic waste materials like fermentable feedstock and manure. The materials are processed to hydrogen by dark and photofermentation. The goal is to “come up with biosystems that could be grouped into a […]
Business is often viewed as an enemy of the environment, but still we feel positive when the stocks of the alternative energy companies begin to do well. Business, by its very logic, is always about money. We know this is a flawed logic because in the end not everything boils down to money. There […]
Researchers from Florida University recently began testing a new field hospital design in the Honduran jungle. U.s. Military and emergency response teams are hopeful that the project will be a success, as each unit would be able to desalinate up to 400 gallons of water per day, and produce enough electricity to power an […]
Scotland based firm ZM Architecture was recently awarded a prize by the International Design Awards for its promising solar technology concept known as the solar lily pad. What makes the most sense about this concept is that it can be implemented with very little environmental impact while saving precious land resources for other uses. […]
The government of California is backing an initiative between the Linde Group and Waste Management to build a liquefied natural gas facility that will produce clean liquid fuel from landfill gas using minicipal waste incinerators. The facility is expected to open in 2009 and will produce up to 13,000 gallons of fuel per day. […]
The X-Prize Foundation, most commonly known for it’s space exploration challenges, has launched a new generation of contests that they hope will have a global impact aned encourage a positive influence on global warming and progress toward clean, green, renewable energy. $100 million will be awarded to prize concepts that promote a world where […]
Eugene Tsui has designed a concept city called The Ultima Tower that would help solve the global population crisis. Acting as a human termite nest, and costing $150 billion, these two mile high green towers would house over one million people in a one mile wide area. Instead of floors, the building’s interior would […]
